Abstract
Rotavirus (RV) is the most common cause of severe gastroenteritis (GE) in infants and young children worldwide and is associated with a significant clinical and economic burden. The objective of this study was to analyze the characteristics, healthcare resource utilization and the direct medical costs related to RVGE hospitalizations in Spain. An observational, multicenter, cross-sectional study was conducted from June 2013 to May 2018 at the pediatric departments of 12 hospitals from different Spanish regions. Children under 5 years of age admitted to the hospital with a confirmed diagnosis of RVGE were selected. Data on clinical characteristics, healthcare resource use and costs were collected from patient records and hospital databases. Most children hospitalized for RVGE did not have any previous medical condition or chronic disease. Forty-seven percent had previously visited the Emergency Room (ER), 27% had visited a primary care pediatrician, and 15% had received pharmacological treatment prior to hospital admission due to an RVGE episode. The average length of a hospital stay for RVGE was 5.6 days, and the mean medical costs of RVGE hospitalizations per episode ranged from 3,940€ to 4,100€. The highest direct medical cost was due to the hospital stay. This study showed a high burden of health resource utilization and costs related to the management of cases of RVGE requiring hospitalization. RV vaccination with high coverage rates should be considered to minimize the clinical and economic impacts of this disease on the health-care system.

Abstract
BACKGROUND Rotavirus (RV) vaccines are available in Spain since 2006 but are not included in the National Immunization Program. RV vaccination has reached an intermediate vaccination coverage rate (VCR) but with substantial differences between provinces. The aim of this study was to assess the ratio of RV gastroenteritis (RVGE) admissions to all-cause hospitalizations in children under 5 years of age in areas with different VCR. METHODS Observational, multicenter, cross-sectional, medical record-based study. All children admitted to the study hospitals with a RVGE confirmed diagnosis during a 5-year period were selected. The annual ratio of RVGE to the total number of all-cause hospitalizations in children < 5 years of age were calculated. The proportion of RVGE hospitalizations were compared in areas with low (< 30%), intermediate (31-59%) and high (> 60%) VCR. RESULTS From June 2013 to May 2018, data from 1731 RVGE hospitalizations (16.47% of which were nosocomial) were collected from the 12 study hospitals. RVGE hospital admissions accounted for 2.82% (95 CI 2.72-3.00) and 43.84% (95% CI 40.53-47.21) of all-cause and Acute Gastroenteritis (AGE) hospitalizations in children under 5 years of age, respectively. The likelihood of hospitalization due to RVGE was 56% (IC95%, 51-61%) and 27% (IC95%, 18-35%) lower in areas with high and intermediate VCR, respectively, compared to the low VCR areas. CONCLUSIONS RVGE hospitalization ratios are highly dependent on the RV VCR. Increasing VCR in areas with intermediate and low coverage rates would significantly reduce the severe burden of RVGE that requires hospital management in Spain. Clinical trial registration Not applicable.

Abstract
Vaccination has reduced rotavirus hospitalizations by 25% in European regions with low-moderate vaccine availability. We aimed to quantify the reduction in hospital costs after the longest period in which Rotarix® and Rotateq® were simultaneously commercially available in Spain. Cases, length of stay (LOS), and diagnosis-related groups (DRGs) were retrieved from the Minimum Basic Data Set. Healthcare expenditure was estimated through the cost accounting system Gescot®. DRGs were clustered: I, non-bacterial gastroenteritis with complications; II, without complications; III, requiring surgical/other procedures or neonatal cases (highest DRG weights). Comparisons between pre (2003-2005)- and post-vaccine (2007-2009) hospital stays and costs by DRG group were made. Rotaviruses were the most common agents of specific-coded gastroenteritis (N = 1657/5012). LOS and extended LOS of rotaviruses fell significantly in 2007-2009 (β-coefficient = -0·43, 95% confidence intervals (95% CI) -0·68 to -0·17; and odds ratio 0·62, 95% CI 0·50-0·76, respectively). Overall, costs attributable to rotavirus hospitalizations fell approximately €244 per patient (95% CI -365 to -123); the decrease in DRG group III was €2269 per patient (95% CI -4098 to -380). We concluded modest savings in hospital costs, largely attributable to cases with higher DRG weights, and a faster recovery. A universal rotavirus vaccination program deserves being re-evaluated, regarding its potential high impact on both at-risk children and societal costs.

Abstract
Rotavirus is a major burden on the Spanish Healthcare System. Rotarix(®) and RotaTeq(®) were simultaneously commercialized in Spain by February, 2007. The objective is to analyze the incidence and seasonality of rotavirus hospitalizations (RH) in Castile-La Mancha (CLM), following the first 3 y of commercialization. A cross-sectional study of the hospital discharge registry's Minimum Basic Data Set (MBDS) in CLM between 2003 and 2009 was performed. We used the Poisson regression model to quantify the percentage of change in the rotavirus incidence rate (IR) for 2007-09 vs. 2003-05, adjusting for age, sex, and province. To analyze changes between epidemic seasons the chi-square test was used. The median IR in 2003-09 was 224.71 per 10(5) [interquartile range (IQR): 185.24-274.70], which represents 60% of hospital admissions due to infectious acute gastroenteritis. The median rate in 2007-09 decreased [incidence rate ratio (IRR): 0.86, 95% CI: 0.78-0.96], significantly in Toledo (IRR: 0.54, 95% CI: 0.39-0.75). An incipient decline at the beginning of the last cold season was observed, preceded by a significant decrease of 68% in the autumn season of 2009. Despite its limited coverage, the rotavirus vaccine may have contributed to decrease RH in CLM.

Abstract
Severe rotavirus gastroenteritis is common in children under 5 years of age. A literature review was performed to investigate the economic and psychosocial impact of rotavirus infection in children in this age group. We retrieved 56 articles on the economic burden of the disease in Europe, 18 of them reported data from Spain; 8 articles were retrieved analysing its psychosocial impact. In Spain, rotavirus is responsible for 14% to 30% of all cases of gastroenteritis, and a quarter of these require hospitalisation. It is also associated with high use of health care resources (emergency and primary care visits). Rotavirus gastroenteritis costs the Spanish national health system EUR 28 million a year and causes productivity loss in two-thirds of parents (mean of 4 days). Taking into account these costs, it was estimated that implementing universal vaccination could prevent 76% to 95% of hospital admissions due to rotavirus gastroenteritis, as well as reduce emergency and paediatric visits, nosocomial infections, and days missed from work (77% reduction). Rotavirus gastroenteritis also has a considerable psychosocial impact on the family, although it is difficult to compare results due to the diversity of study designs and the low specificity of the measurement tools used. It also causes high stress among parents, adding to their workload and adversely affecting their quality of life.

Abstract
BACKGROUND A substantial number of surveillance studies have documented rotavirus prevalence among children admitted for dehydrating diarrhea. We sought to establish global seasonal patterns of rotavirus disease before the introduction of widespread vaccination. METHODS We reviewed studies of rotavirus detection in children with diarrhea published since 1995. We assessed potential relationships between seasonal prevalence and locality by plotting the average monthly proportion of diarrhea cases positive for rotavirus according to geography, country development and latitude. We used linear regression to identify variables that were potentially associated with the seasonal intensity of rotavirus. RESULTS Among a total of 99 studies representing all 6 geographic regions of the world, patterns of year-round disease were more evident in low- and low-middle income countries compared with upper-middle and high-income countries where disease was more likely to be seasonal. The level of country development was a stronger predictor of strength of seasonality (P = 0.001) than geographic location or climate. However, the observation of distinctly different seasonal patterns of rotavirus disease in some countries with similar geographic location, climate and level of development indicate that a single unifying explanation for variation in seasonality of rotavirus disease is unlikely. CONCLUSION While no unifying explanation emerged for varying rotavirus seasonality globally, the country income level was somewhat more predictive of the likelihood of having seasonal disease than other factors. Future evaluation of the effect of rotavirus vaccination on seasonal patterns of disease in different settings may help understand factors that drive the global seasonality of rotavirus disease.

Abstract
BACKGROUND Despite its high incidence among children under the age of five, little is known about the burden of pediatric gastroenteritis outside the medical setting. The objective of this study was to describe the burden of acute gastroenteritis among children residing in the United Arab Emirates, including those not receiving medical care. METHODS A quantitative cross-sectional survey of 500 parents of children under 5 years of age who had suffered from acute gastroenteritis the preceding three months was conducted in the cities of Abu Dhabi and Al Ain. Data collected included respondent characteristics, disease symptoms, medical care sought, and parental expenditures and work loss. Data were analyzed using parametric and non-parametric statistical methods. RESULTS Vomiting and diarrhea episodes lasted on average between 3 and 4 days. Overall, 87% of parents sought medical care for their children; 10% of these cases required hospitalization with an average length of stay of 2.6 days. When medical care was sought, the average parental cost per gastroenteritis episode was US$64, 4.5 times higher than with home care only (US$14). Nearly 60% of this difference was attributable to co-payments and medication use: 69% of children used oral rehydration solution, 68% antiemetics, 65% antibiotics and 64% antidiarrheals. Overall, 38 parents missed work per 100 gastroenteritis episodes for an average of 1.4 days. CONCLUSIONS Given its high incidence, pediatric gastroenteritis has an important financial and productivity impact on parents in the United Arab Emirates. To reduce this impact, efforts should be made both to prevent acute gastroenteritis and to optimize its treatment.

Abstract
BACKGROUND Rotavirus affects 95% of children worldwide by age 5 years and is the leading cause of severe dehydrating diarrhea. The objective of this review was to estimate the burden of rotavirus gastroenteritis (RVGE) in the Western European pediatric population. METHODS A comprehensive literature search (1999-2010) was conducted in PubMed and other sources (CDC; WHO, others). Data on the epidemiology and burden of RVGE among children < 5 years-old in Western Europe --including hospital-acquired disease--were extracted. RESULTS 76 studies from 16 countries were identified. The mean percentage of acute gastroenteritis (AGE) cases caused by rotavirus ranged from 25.3%-63.5% in children < 5 years of age, peaking during winter. Incidence rates of RVGE ranged from 1.33-4.96 cases/100 person- years. Hospitalization rates for RVGE ranged from 7% to 81% among infected children, depending on the country. Nosocomial RVGE accounted for 47%-69% of all hospital-acquired AGE and prolonged hospital stays by 4-12 days. Each year, RVGE incurred $0.54- $53.6 million in direct medical costs and $1.7-$22.4 million in indirect costs in the 16 countries studied. Full serotyping data was available for 8 countries. G1P[8], G2P[4], G9P[8], and G3P[8] were the most prevalent serotypes (cumulative frequency: 57.2%- 98.7%). Serotype distribution in nosocomial RVGE was similar. CONCLUSIONS This review confirms that RVGE is a common disease associated with significant morbidity and costs across Western Europe. A vaccine protecting against multiple serotypes may decrease the epidemiological and cost burden of RVGE in Western Europe.

Abstract
BACKGROUND In Bolivia, in 2008, the under-five mortality rate is 54 per 1000 live births. Diarrhea causes 15% of these deaths, and 40% of pediatric diarrhea-related hospitalizations are caused by rotavirus illness (RI). Rotavirus vaccination (RV), subsidized by international donors, is expected to reduce morbidity, mortality, and economic burden to the Bolivian state. Estimates of illness and economic burden of RI and their reduction by RV are essential to the Bolivian state's policies on RV program financing. The goal of this report is to estimate the economic burden of RI and the cost-effectiveness of the RV program. METHODS To assess treatment costs incurred by the healthcare system, we abstracted medical records from 287 inpatients and 6751 outpatients with acute diarrhea between 2005 and 2006 at 5 sentinel hospitals in 4 geographic regions. RI prevalence rates were estimated from 4 years of national hospital surveillance. We used a decision-analytic model to assess the potential cost-effectiveness of universal RV in Bolivia. RESULTS Our model estimates that, in a 5-year birth cohort, Bolivia will incur over US$3 million in direct medical costs due to RI. RV reduces, by at least 60%, outpatient visits, hospitalizations, deaths, and total direct medical costs associated with rotavirus diarrhea. Further, RV was cost-savings below a price of US$3.81 per dose and cost-effective below a price of US$194.10 per dose. Diarrheal mortality and hospitalization inputs were the most important drivers of rotavirus vaccine cost-effectiveness. DISCUSSION Our data will guide Bolivia's funding allocation for RV as international subsidies change.

Abstract
BACKGROUND Current assessments of the burden of rotavirus (RV)-related gastroenteritis are needed to evaluate the potential benefits of RV immunization interventions. The objective of the present study was to characterize the burden of RV gastroenteritis among children presenting in outpatient settings with gastroenteritis. METHODS Between January and June 2005, 395 children younger than three years of age presenting with gastroenteritis symptoms (at least three watery or looser-than-normal stools, or forceful vomiting within the previous 24 h period) were recruited from 59 Canadian clinics and followed for two weeks. Stool specimens were tested for the RV antigen. Gastroenteritis-related symptoms, health care utilization, parental work loss and other cases of gastroenteritis in the household were assessed by questionnaires and daily symptom cards that were completed by caregivers. RESULTS Of 336 conclusive test results, 55.4% were RV positive (RV+). In addition to diarrhea, 67.2% and 89.3% of RV+ children experienced fever or vomiting, respectively. Compared with RV-negative (RV-) children, RV+ children were more likely to experience the three symptoms concurrently (57.0% versus 26.7%; P<0.001), to be hospitalized (12.9% versus 3.9%; P=0.008) and to induce parental work loss (53.8% versus 37.3%; P=0.003). The median duration of gastroenteritis was eight days for RV+ children (nine days for RV- children). Additional cases of gastroenteritis were present in 46.8% of households in the RV+ group (51.3% of households in the RV- group). CONCLUSIONS RV gastroenteritis cases were more severe than other gastroenteritis cases, were hospitalized more often and were associated with considerably more work loss.

Abstract
Background Rotavirus is the most common cause of severe gastroenteritis among young children in Spain and worldwide. We evaluated hospitalizations due to community and hospital-acquired rotavirus gastroenteritis (RVGE) and estimated related costs in children under 5 years old in Catalonia, Spain. Results We analyzed hospital discharge data from the Catalan Health Services regarding hospital admissions coded as infectious gastroenteritis in children under 5 for the period 2003-2008. In order to estimate admission incidence, we used population estimates for each study year published by the Statistic Institut of Catalonia (Idescat). The costs associated with hospital admissions due to rotavirus diarrhea were estimated for the same years. A decision tree model was used to estimate the threshold cost of rotavirus vaccine to achieve cost savings from the healthcare system perspective in Catalonia. From 2003 through 2008, 10655 children under 5 years old were admitted with infectious gastroenteritis (IGE). Twenty-two percent of these admissions were coded as RVGE, yielding an estimated average annual incidence of 104 RVGE hospitalizations per 100000 children in Catalonia. Eighty seven percent of admissions for RVGE occurred during December through March. The mean hospital stay was 3.7 days, 0.6 days longer than for other IGE. An additional 892 cases of presumed nosocomial RVGE were detected, yielding an incidence of 2.5 cases per 1000 child admissions. Total rotavirus hospitalization costs due to community acquired RVGE for the years 2003 and 2008 were 431,593 and 809,224 €, respectively. According to the estimated incidence and hospitalization costs, immunization would result in health system cost savings if the cost of the vaccine was 1.93 € or less. At a vaccine cost of 187 € the incremental cost per hospitalization prevented is 195,388 € (CI 95% 159,300; 238,400). Conclusions The burden of hospitalizations attributable to rotavirus appeared to be lower in Catalonia than in other regions of Spain and Europe. The relatively low incidence of hospitalization due to rotavirus makes rotavirus vaccination less cost-effective in Catalonia than in other areas with higher rotavirus disease burden.

Abstract
Background The effect of rotavirus in developed countries is mainly economic. This study aimed to assess the indirect costs induced by rotavirus acute gastroenteritis (RVAGE) in Spain. Methods A prospective observational study was conducted from October 2008 to June 2009. It included 682 children up to 5 years of age with acute gastroenteritis (AGE) who attended primary care (n = 18) and emergency room/hospital settings (n = 10), covering the regions of Galicia and Asturias (North-west Spain). All non-medical expenses incurred throughout the episode were recorded in detail using personal interviews and telephone contact. Results Among the 682 enrolled children, 207 (30.4%) were rotavirus positive and 170 (25%) had received at least one dose of rotavirus vaccine. The mean (standard deviation) indirect cost caused by an episode of AGE was estimated at 135.17 (182.70) Euros. Costs were 1.74-fold higher when AGE was caused by rotavirus compared with other etiologies: 192.7 (219.8) Euros vs. 111.6 (163.5) Euros (p < .001). The costs for absenteeism were the most substantial with a mean of 91.41 (134.76) Euros per family, resulting in a loss of 2.45 (3.17) days of work. In RVAGE patients, the absenteeism cost was 120.4 (154) Euros compared with 75.8 (123) for the other etiologies (p = .002), because of loss of 3.5 (3.6) vs 1.9 (2.9) days of work (p < .001). Meals costs were 2-fold-higher (48.5 (55) vs 24.3 (46) Euros, p < .001) and travel costs were 2.6-fold-higher (32 (92) vs 12.5 (21.1) Euros, p = .005) in RVAGE patients compared with those with other etiologies. There were no differences between RVAGE and other etiologies groups regarding costs of hiring of caregivers or purchase of material. Patients with RVAGE were admitted to hospital more frequently than those with other etiologies (47.8% vs 14%, p < .001). Conclusions Rotavirus generates a significant indirect economic burden. Our data should be considered in the decision-making process of the eventual inclusion of rotavirus vaccine in the national immunization schedule of well developed countries.

Abstract
BACKGROUND Rotavirus is the most common cause of gastroenteritis in young children worldwide. The aim of the study was to assess the health outcomes and the economic impact of a universal rotavirus vaccination programme with RotaTeq, the pentavalent rotavirus vaccine, versus no vaccination programme in Spain. METHODS A birth cohort was followed up to the age of 5 using a cohort model. Epidemiological parameters were taken from the REVEAL study (a prospective epidemiological study conducted in Spain, 2004-2005) and from the literature. Direct and indirect costs were assessed from the national healthcare payer and societal perspectives by combining health care resource utilisation collected in REVEAL study and unit costs from official sources. RotaTeq per protocol efficacy data was taken from a large worldwide rotavirus clinical trial (70,000 children). Health outcomes included home care cases, General Practioner (GP)/Paediatrician, emergency department visits, hospitalisations and nosocomial infections. RESULTS The model estimates that the introduction of a universal rotavirus vaccination programme with RotaTeq (90% coverage rate) would reduce the rotavirus gastroenteritis (RVGE) burden by 75% in Spain; 53,692 home care cases, 35,187 GP/Paediatrician visits, 34,287 emergency department visits, 10,987 hospitalisations and 2,053 nosocomial infections would be avoided. The introduction of RotaTeq would avoid about 76% of RVGE-related costs from both perspectives: euro22 million from the national health system perspective and euro38 million from the societal perspective. CONCLUSIONS A rotavirus vaccination programme with RotaTeq would reduce significantly the important medical and economic burden of RVGE in Spain.

Abstract
BACKGROUND The highest incidence of rotavirus gastroenteritis has generally been reported in children 6-24 months of age. Young infants are thought to be partially protected by maternal antibodies acquired transplacentally or via breast milk. The purpose of our study was to assess the age distribution of children with confirmed community-acquired rotavirus gastroenteritis presenting to an urban referral hospital. METHODS Children presenting to The Children's Hospital of Philadelphia with acute gastroenteritis have been monitored for the presence of rotavirus antigen in the stool by ELISA (followed by genotyping if ELISA-positive) since the 1994-95 epidemic season. RESULTS Over the last 12 rotavirus seasons prior to the introduction of the pentavalent rotavirus vaccine in 2006, stool specimens from 1646 patients tested positive for community-acquired rotavirus infection. Gender or age was not recorded in 6 and 5 cases, respectively. Overall, 58% of the cases occurred in boys. G1 was the predominant VP7 serotype, accounting for 72% of cases. The median (IQR) age was 11 (5-21) months. A total of 790 (48%) cases occurred in children outside the commonly quoted peak age range, with 27% in infants <6 months of age and 21% in children >24 months of age. A total of 220 (13%) cases occurred during the first 3 months of life, and the highest number of episodes per month of age [97 (6%)] was observed during the second month of life. CONCLUSIONS The incidence of community-acquired rotavirus gastroenteritis monitored over 12 seasons in the prevaccine era at a major university hospital was nearly constant for each month of age during the first year of life, revealing an unexpectedly high incidence of symptomatic rotavirus disease in infants <3 months old. A sizeable fraction of cases occurred in children too young to have been vaccinated according to current recommendations.

Abstract
This study assessed the immunogenicity and safety of a human rotavirus vaccine RIX4414; the effect of co-administration of childhood vaccines on the immune responses was also assessed. Healthy infants aged 6-14 weeks received two doses of RIX4414/placebo concomitantly with the primary childhood vaccination (Infanrix hexa, Infanrix quinta,Meningitec and/or Prevnar), respecting the vaccination schedule of each country. Anti-rotavirus IgA seroconversion rate (ELISA cut-off 20 U/ml) was measured pre-vaccination and 1-2 months post-Dose 2. Immune response against diphtheria, tetanus, pertussis, hepatitis B, Haemophilus influenzae type b, inactivated polio virus, pneumococcal polysaccharide conjugate (France and Germany) and meningococcal group C conjugate vaccines (Spain) were measured approximately 1-month post-Dose 3. An overall anti-rotavirus IgA seroconversion rate of 86.5%(95% CI: 83.9-88.8) was observed in the RIX4414 group 1-month post-Dose 2. The seroconversion rate in Finland and Italy (3 and 5-month schedule) was 94.6%(95% CI: 90.0-97.5) and 92.3%(95% CI: 64.0-99.8), respectively. Immune response to the childhood vaccines was unaffected following co-administration with RIX4414. Reactogenicity profile was similar for RIX4414 and placebo groups. RIX4414 was immunogenic and well tolerated in European infants and the co-administration of routine childhood vaccines with RIX4414 did not negatively impact the immune responses to these vaccines.

Abstract
OVERVIEW Hospital discharge forms with specific codes for rotavirus gastroenteritis in children 0 to 14 years of age were reviewed in the period 2003-2005 in the province of Ferrara. RESULTS A total of 4,238 children were admitted to the pediatric departments; 151 patients were diagnosed with rotavirus gastroenteritis. The average annual rate of hospitalization for rotavirus gastroenteritis was 1.54/1,000 children <14 years of age and 2.9/1,000 children <5 years of age. Most hospitalizations (72%) involved children aged <60 months. The average length of hospital stay was about 5 days. Considering the Emilia Romagna regional reimbursement codes referable to rotavirus disease, the estimated costs of our 151 cases range from 214,033 euros to 341,832 euros. CONCLUSIONS The results of this study contribute to the awareness of rotavirus epidemiology in Italy and underline the potential impact of rotavirus vaccination in our province.

Abstract
BACKGROUND A thorough epidemiological surveillance and a good understanding of the burden of diseases associated to VZV are crucial to asses any potential impact of a prevention strategy. A population-based retrospective epidemiological study to estimate the burden of herpes zoster requiring hospitalization in Spain was conducted. METHODS This study was conducted by using data from the national surveillance system for hospital data, Conjunto Mínimo Básico de Datos (CMBD). Records of all patients admitted to hospital with a diagnosis of herpes zoster (ICD-9-MC codes 053.0-053.9) during a 7-year period (1998-2004) were selected. RESULTS A total of 23,584 hospitalizations with a primary or secondary diagnosis of herpes zoster in patients > or = 30 years of age were identified during the study period. Annually there were 13.4 hospitalizations for herpes zoster per 100,000 population in patients > or = 30 years of age. The rate increases with age reaching a maximum in persons > or = 80 years of age (54.3 admissions per 100,000 population >80 years of age). The mean cost of a hospitalization for herpes zoster in adult patients was 3,720 euro. The estimated annual cost of hospitalizations for herpes zoster in patients > or = 30 years of age in Spain was 12,731,954 euro. CONCLUSION Herpes zoster imposes an important burden of hospitalizations and result in large cost expenses to the Spanish National Health System, especially in population older than 50 years of age.

Abstract
Diarrhoeal illnesses are the most frequent of notifiable diseases in Aragon. Physicians notify diarrhoea cases with presumed infectious origin on a weekly basis. Following an increase in 2005-2006, we aimed to identify the responsible organism(s) in order to inform control measures. We described seasonality of diarrhoea notifications for 1998-2004 and 2005-2006. We calculated correlations between diarrhoea notifications and enteric pathogens diagnosed in two Aragonese laboratories, and applied linear regression using coefficients of determination (r2). In 2005-2006 the winter peak of diarrhoea notifications increased from 2494 to 3357 weekly cases (34.6%) and the peak in Rotavirus diagnoses from 15 to 39 weekly cases. The correlation of diarrhoea notifications with Rotavirus was 0.05 in 1998-2004 and 0.42 in 2005-2006. The model for 1998-2004 included Salmonella enterica, Giardia lamblia and Clostridium difficile (r2=0.08) and for 2005-2006 Rotavirus and Astrovirus (r2=0.24). Our results suggest that Rotavirus contributed to the increase of diarrhoea notifications. We recommend determining the disease burden of Rotavirus in order to guide vaccination policies.

Abstract
BACKGROUND Rotavirus (RV), is a member of the Reoviridae family and an important etiological agent of acute viral gastroenteritis in the young. Rotaviruses have a wide host range infecting a broad range of animal species, however little is known about rotavirus infection in exotic animals. In this paper we report the first characterisation of a RV strain from a giraffe calf. RESULTS This report describes the identification and detailed molecular characterisation of a rotavirus strain detected from a 14-day-old Giraffe (Giraffa camelopardalis), presenting with acute diarrhea. The RV strain detected from the giraffe was characterized molecularly as G10P[11]. Detailed sequence analysis of VP4 and VP7 revealed significant identity at the amino acid sequence level to Bovine RV (BoRV). CONCLUSION This study demonstrates the need for continuous surveillance of RV strains in various animal populations, which will facilitate the identification of rotavirus hosts not previously reported. Furthermore, extending typical epidemiology studies to a broader host range will contribute to the timely identification of new emerging strain types.

Abstract
BACKGROUND Human rotavirus (HRV) is the most common pathogen causing severe diarrhea among infants and young children worldwide. This study aims to understand rotavirus epidemiology and its variation in the period of 2001-2006 in Lanzhou, Gansu Province, China, and to provide an epidemiological basis for the development of rotavirus vaccine. METHODS A total of 1019 stool specimens were collected from patients with acute diarrhea admitted to the First Hospital of Lanzhou University from 2001 to 2006, who were younger than 5 years old. Dako IDEIATM kits were used for detection of rotavirus, and RT-PCR was performed for determination of G serotype and P genotype of the rotavirus. RESULTS Rotavirus was present in 51.6% (526) of the 1019 specimens. G serotype identified G3 at 40.9%, G2 14.6%, G1 22.2% and G9 1.9%. Mixed-G infection was observed in 4.4% and non-typeable infection 16.0%. P genotype was observed in 372 samples, of which P[8] accounted for 186 cases (50.0%), P[4] 72 cases (19.4%), mixed-P infection 2 cases (0.5%), and non-typeable cases 112 (30.1%). G3 was the most prevalent G serotype found in this study from 2001 to 2004, G2 was the most prevalent G serotype (34.4%) from 2004 to 2005, and G1 (61.5%) was the most prevalent strain from 2005 to 2006. G9 was detected in 10 cases (1.9%) and G4 was not detected during this 5-year period. P[8] was the most prevalent P genotype found over the 5 consecutive years of this study, although there was a significant transition of P genotype from 2004 to 2005 with P[4] (45%) identified as the predominant P genotype, followed by P[8] (22.1%). The predominant G-P combination was P[8]G1 (33.6%), followed by P[8]G3 (32.1%) and P[4]G2 (17.2%). Rotavirus diarrhea admissions peaked between October and December. Continuous surveillance showed that the incidence rate of rotavirus was the highest in infants aged 6-23 months, averaging 11.0-11.9 months. CONCLUSIONS Five years of continuous surveillance showed that rotavirus remains the most significant viral agent causing diarrhea hospitalization among children under 5 years old in Lanzhou, China although the predominant strain of rotavirus varies between years. Mixed-G serotype infection also appears to occur at a relatively high rate in Lanzhou.

Abstract
Rotavirus is the main cause of severe, dehydrating diarrhoea in infants and young children. In industrialized countries, pediatric rotavirus gastroenteritis (PRGE) is responsible for high morbidity, particularly among children under 3 years of age attending day care centers (DCCs). The objectives of this study were to estimate the incidence, management and cost of PRGE in DCCs. We also described the nature of group A rotavirus genotypes. This study also compared the performance of different diagnostic techniques. The study was conducted from November 2004 to May 2005. Children aged less than 36 months, attending a participating DCC at least 4 times a week were included in the study. For any episode of acute gastroenteritis (AGE), defined as the occurrence of 3 or more watery or looser than normal stools and/or forceful vomiting within a 24 h period, a fecal specimen was tested by Elisa test IDEIA Rotavirus (Dako) and the immunochromatographic test VIKIA Rota-Adeno (BioMérieux). Sequencing by RT-PCR was performed to identify the rotavirus genotype. Among the 41 DCCs contacted, 18 (43.9%) agreed to participate. Out of 966 children, 547 attended a participating DCC at least 4 times a week and met the inclusion criteria. A total of 302 were included in the study. The clinical diagnosis of AGE was confirmed and validated, by the Elisa test, in 63 fecal specimens, of which 29 (46%) were positive for rotavirus antigen, with a predominance of P[8]G9 (86%). Our results showed good sensitivity and specificity for the VIKIA and Elisa methods when compared to RT-PCR. Among the PRGE cases, 36% were male and the median age was 12.2 months. The first rotavirus case was observed in December 2004 with a peak in January 2005. The incidence of PRGE cases was 2.2 [1.4-3.0] per 100 child-months in children aged less than 36 months of age, increasing to 3.4 per 100 child-months among children aged less than 24 months. Vomiting (P<0.0005) and behavior modification (P<0.001) were significantly more frequent for PRGE cases. A total of 85.7% PRGE cases sought medical attention. In 58.3% of these cases, at least one parent had to miss work for a mean duration of 2.1 days. The total cost of rotavirus cases seeking medical attention (with or without prescribed medication, days off work for parents or additional diaper consumption) was estimated at 275.54 euros/case. The PRGE incidence rate is similar to that estimated in European studies conducted in DDC. These findings confirm that rotavirus transmission occurs not only in DCCs but within the family. This is the first study to give an estimate of the incidence and the cost of rotavirus infection in DCCs in France.

Abstract
Rotavirus is one of the most common causes of gastroenteritis worldwide. With the commercialisation of effective rotavirus vaccines in Europe in sight, it is necessary to provide studies which evaluate the disease burden. The aim of this study is two-fold, on one hand, to determine the burden of the rotavirus disease in Spanish children under the age of five, and on the other, to estimate the economic cost of these hospitalizations. The study was undertaken during a 5 year period (2000-2004). The rotavirus hospitalization rate was determined using the Minimum Basic Data Set of the national hospital discharge register. The observed data were compared with those expected by applying a model developed by the Centers for Disease Control and Prevention (CDC) adapted for European Countries. The financial expense of these hospitalizations was estimated. Of all admissions coded as gastroenteritis, 31.6% were due to rotavirus. The hospitalization rate by rotavirus was 480 cases per 100,000 children under five. These data are within the confidence range proposed by the adapted CDC model. The financial expense due to hospitalizations reaches 123,262 euros yearly in a Spanish University Hospital. In conclusion, rotavirus contributes significantly to the hospitalization of acute gastroenteritis. The rate of hospitalization by rotavirus is higher compared to other studies carried out in Spain. In view of future commercialisation of rotavirus vaccines, more in-depth analysis considering direct and indirect costs are necessary.

Abstract
Background This study aims to describe and analyze hospital admissions in Spain due to rotavirus infections among children aged 5 years or under during the period 2001–2005, along with the associated health cost. Methods To update estimates of rotavirus hospitalizations rates in Spain, we conducted a retrospective study of 5 years of national hospitalization data associated with acute gastroenteritis using the Minimum Basic Data Set. Results During the study period, a total of 17.1% of all admissions due to acute gastroenteritis of any etiology in children aged ≤ 5 years were attributable to rotavirus infection as determined by the rotavirus-specific International Classification of Diseases, ninth revision, Clinical Modification code. A mean incidence of 135 hospital admissions attributable to rotavirus per 100,000 children aged ≤ 5 years was found. Hospitalizations associated with rotavirus had a marked winter-time seasonality. The estimated cost of hospital admission attributable to rotavirus has risen from 3 million euros estimated for 2001 to almost 7 million euros estimated in 2005. Conclusion Rotavirus gastroenteritis remains an important cause of hospitalizations in Spanish children, mostly during the winter season.

Abstract
Rotavirus is the most common cause of gastroenteritis in children aged <5 years old, two new vaccines have recently been developed which can prevent associated morbidity and mortality. While apparently safe and efficacious, it is also important to establish whether rotavirus immunization is cost effective. A decision analytical model which employs data from a review of published evidence is used to determine the cost effectiveness of a rotavirus vaccine. The results suggest that some of the health sector costs, and all of the societal costs, of rotavirus gastroenteritis in children can be avoided by an immunization programme. The additional cost to the health sector may be considered worthwhile if there is a sufficient improvement in the quality-of-life of children and parents affected by gastroenteritis; this study did not find any evidence of research which has measured the utility gains from vaccination.

Abstract
A group of European experts in infectious diseases and vaccinology has met on several occasions to assess the rationale for universal vaccination against rotavirus infection of infants in Europe. On the basis of the available data, we concluded that vaccination was the best approach to prevent severe rotavirus gastroenteritis, and that European countries should consider implementing rotavirus vaccination in their routine immunisation programmes. The main barrier to the implementation of rotavirus vaccination in Europe is a general lack of awareness of stakeholders, policymakers, health-care professionals, and parents about rotavirus disease and the advantages of vaccination. Further studies on the cost of the disease and the benefit of vaccination, together with raising awareness are necessary steps to ensure successful implementation of rotavirus vaccination in Europe.

Abstract
BACKGROUND AND OBJECTIVE Infectious intestinal diseases are highly prevalent, and among them sporadic cases are the most common processes. The aim of this study was to estimate the incidence of sporadic cases diagnosed in a healthcare district of Castellón (Spain) in the year 2004, and to compare them with those of the year 2000. MATERIAL AND METHOD Based on routine coprocultures and individual demographic data of each patient, we calculated the population rates by age for the more frequent microorganisms, especially detailed for children up to 5 years of age. We report the results of the year 2004, and compare these with the previous study of the year 2000. RESULTS Campylobacter showed the highest rate (1.01 x 103), followed by Salmonella (0.75), each without significant differences regarding the year 2000. The rate of rotavirus cases (0.65) was smaller than in 2000; and for adenovirus 2004 was an atypical seasonal year. In children younger than 3 years, rates were 26.54; 10.23 and 11.75. As in the previous study, the age-distribution in children < 5 years was very particular. An U inverted shape was seen for Campylobacer, and the rates for rotavirus decreased after the peak observed in the youngest group (< 6 months). Among hospitalized patients rotavirus was the most common and Campylobacter the less common. CONCLUSIONS The epidemiological traits of the rates by age until the age of five are characteristic for each microorganism, as are the proportions of hospitalization. Rates of Campylobacter and Salmonella in the year 2004 were similar to the year 2000, but a decrease in the rotavirus rates was observed.

Abstract
Rotavirus is the leading cause of diarrhea in infants. In developed countries, this infection leads to considerable morbidity with a high number of hospitalizations and medical interventions in the winter season, giving rise to substantial medical and social costs. In developing countries, rotavirus is a major cause of mortality in infants due to dehydration, with an estimated 600.000 deaths or more per year worldwide. A vaccine that is easy administrated, safe and with high efficacy would be the ideal means to reduce the burden of this disease and its high economic and social cost and to decrease the number of deaths in low-income countries. Recently, the results of two well-designed clinical trials with a large number of subjects have been reported. Both studies, which used different vaccines, reported high efficacy in the prevention of severe gastroenteritis and hospitalizations caused by rotavirus. When these vaccines become available in Europe, a reduction in hospitalizations, medical consultations, and days of work lost can be expected.

Abstract
BACKGROUND Rotavirus is the most common pathogen causing severe dehydrating diarrhea in infants and young children worldwide. Any decision on implementation of rotavirus vaccination will be strongly influenced by the expected reduction in severe and therefore costly outcomes associated with rotavirus infection. The aim of this study was to provide data on hospitalization of young children with rotavirus infection in Austria. METHODS The data were derived from active hospital-based sentinel surveillance for rotavirus during the period 1997 to 2003. RESULTS During this period 25,600 children<15 years of age were hospitalized with acute laboratory-confirmed rotavirus gastroenteritis, the infection showing seasonal peaks between February and March. In 5 % of the cases first symptoms of diarrhea occurred at a minimum of 48 hours after hospital admission, indicating healthcare-associated origin of infection. The mean annual incidence of hospitalization per 100,000 population for the age group<5 years was 766 and for those<2 years 1742, the latter meaning that 1 in 60 Austrian children up to 2 years of age required hospitalization. An average peak incidence was observed between 8 and 14 months of age, with an average of 68% of the reported cases occurring in children aged<or=24 months. The mean length of hospital stay was 4.7 days, resulting in 17,200 rotavirus-associated hospital days per year. CONCLUSIONS The observed incidence of hospitalization due to rotavirus in Austria is slightly higher than that reported in other industrialized countries. Our results reflect the considerable number of rotavirus-associated pediatric hospital in-patient days per year and the substantial annual direct costs of hospital care.

Abstract
Rotaviruses are a major cause of hospitalizations for acute gastroenteritis in developed countries. This review shows the burden of rotavirus disease in < 5-year-old children in Europe. An estimated 72,000-77,000 hospitalizations for community-acquired rotavirus disease occur annually in the 23 million under-fives living in the European Union (EU-25), with a median cost of Euro 1417 per case. Annual hospitalization incidence rates range from 0.3 to 11.9/1000 children < 5 years old (median 3/1000). The median proportion of hospital-acquired rotavirus disease among all cases of hospitalization for rotavirus disease is estimated to be 21%. Countries of the EU-25 require information on the burden of rotavirus disease to support introduction of rotavirus vaccines. Data on cases treated at home, medical visits, and emergency wards as well as rotavirus-associated deaths are limited. To fully evaluate the impact and effectiveness of rotavirus vaccination programmes in Europe, additional epidemiological studies will be critical and desirable.

Abstract
The number of cost-of-illness (COI) studies has expanded considerably over time. One outcome of this growth is that the reported COI estimates are inconsistent across studies, thereby raising concerns over the validity of the estimates and methods. Several factors have been identified in the literature as reasons for the observed variation in COI estimates. To date, the variation in the methods used to calculate costs has not been examined in great detail even though the variations in methods are a major driver of variation in COI estimates. The objective of this review was to document the variation in the methodologies employed in COI studies and to highlight the benefits and limitations of these methods. The review of COI studies was implemented following a four-step procedure: (i) a structured literature search of MEDLINE, JSTOR and EconLit; (ii) a review of abstracts using pre-defined inclusion and exclusion criteria; (iii) a full-text review using pre-defined inclusion and exclusion criteria; and (iv) classification of articles according to the methods used to calculate costs. This review identified four COI estimation methods (Sum_All Medical, Sum_Diagnosis Specific, Matched Control and Regression) that were used in categorising articles. Also, six components of direct medical costs and five components of indirect/non-medical costs were identified and used in categorising articles.365 full-length articles were reflected in the current review following the structured literature search. The top five cost components were emergency room/inpatient hospital costs, outpatient physician costs, drug costs, productivity losses and laboratory costs. The dominant method, Sum_Diagnosis Specific, was a total costing approach that restricted the summation of medical expenditures to those related to a diagnosis of the disease of interest. There was considerable variation in the methods used within disease subcategories. In several disease subcategories (e.g. asthma, dementia, diabetes mellitus), all four estimation methods were represented, and in other cases (e.g. HIV/AIDS, obesity, stroke, urinary incontinence, schizophrenia), three of the four estimation methods were represented. There was also evidence to suggest that the strengths and weaknesses of each method were considered when applying a method to a specific illness. Comparisons and assessments of COI estimates should consider the method used to estimate costs both as an important source of variation in the reported COI estimates and as a marker of the reliability of the COI estimate.

Abstract
Rotavirus is a major cause of gastroenteritis in children throughout Europe and the world. In addition to causing morbidity and mortality in children, rotavirus gastroenteritis (RVGE) creates a major economic burden on health care systems and families in Europe. The costs of hospital admissions for RVGE and nosocomial infections generate significant medical treatment costs throughout the region. Less information is available on the costs associated with less severe episodes and the costs borne by families, including lost time from work. The availability of rotavirus vaccines presents an effective opportunity to prevent RVGE and these associated economic costs, as well as providing protection to each child and hence benefiting the child's family. The adoption of rotavirus vaccine by health authorities in Europe will require a comparison of the costs and benefits. Economic evaluations that compare the costs of vaccination to the economic benefits of rotavirus vaccination will provide an estimate of its financial impact on health care systems and society. However, to provide a complete picture, economic evaluations of rotavirus vaccines will need to account for both the reduced costs and the reduced morbidity from prevented RVGE. Cost-effectiveness analyses based on quality-adjusted life years (QALYs) provide a systematic approach for assessing vaccination as a health investment, comparing the incremental costs associated with rotavirus vaccination and the reduced morbidity and mortality. QALYs provide a standardized approach for quantifying and comparing reductions in health-related quality of life and premature mortality. Although methodologic limitations exist in applying the QALY approach to childhood vaccines, their use in cost effectiveness analyses allows decision makers to consider the full health benefits of rotavirus and other vaccines.
