Abstract
Despite ongoing control efforts, rabies remains an endemic zoonotic disease in many countries. Determining high-risk areas and the space-time patterns of rabies spread, as it relates to epidemiologically important factors, can support policymakers and program managers alike to develop evidence-based targeted surveillance and control programs. In this One Health approach which selected Thailand as the example site, the location-based risk of contracting dog-mediated rabies by both human and animal populations was quantified using a Bayesian spatial regression model. Specifically, a conditional autoregressive (CAR) Bayesian zero-inflated Poisson (ZIP) regression was fitted to the reported human and animal rabies case counts of each district, from the 2012–2017 period. The human population was used as an offset. The epidemiologically important factors hypothesized as risk modifiers and therefore tested as predictors included: number of dog bites/attacks, the population of dogs and cats, number of Buddhist temples, garbage dumps, animal vaccination, post-exposure prophylaxis, poverty, and shared administrative borders. Disparate sources of data were used to improve the estimated associations and predictions. Model performance was assessed using cross-validation. Results suggested that accounting for the association between human and animal rabies with number of dog bites/attacks, number of owned and un-owned dogs; shared country borders, number of Buddhist temples, poverty levels, and accounting for spatial dependence between districts, may help to predict the risk districts for dog-mediated rabies in Thailand. The fitted values of the spatial regression were mapped to illustrate the risk of dog-mediated rabies. The cross-validation indicated an adequate performance of the spatial regression model (AUC = 0.81), suggesting that had this spatial regression approach been used to identify districts at risk in 2015, the cases reported in 2016/17 would have been predicted with model sensitivity and specificity of 0.71 and 0.80, respectively. While active surveillance is ideal, this approach of using multiple data sources to improve risk estimation may inform current rabies surveillance and control efforts including determining rabies-free zones, and the roll-out of human post-exposure prophylaxis and anti-rabies vaccines for animals in determining high-risk areas. Bayesian spatial regression was used to quantify location-based risk of dog-mediated rabies Available and publicly accessible data from disparate sources were gathered Risk was estimated using the association between Risk estimates were compared over time to determine the prediction ability Study suggests while active surveillance is ideal, using multiple data sources may improve risk estimation

Abstract
OBJECTIVES The World Health Organization recommends a 2-dose rabies pre-exposure prophylaxis (PrEP) regimen. This study aimed to compare the immunogenicity of rabies PrEP regimens co-administered with inactivated quadrivalent influenza vaccine (IIV4). METHODS Children aged 3 to 9 years were randomly assigned (2:2:1) to receive 0.25 mL of chromatographically purified Vero cell rabies vaccine intramuscularly: Group A at day 0, 7 with IIV4; Group B at day 0, 28 with IIV4; Group C at day 0, 7. A booster-dose of CPRV was given on day 365. Primary outcome was the proportion of children with protective rabies virus neutralizing antibody (RVNA) ≥ 0.5 IU/mL, on day 42 and 7 days post-booster. RESULTS From November 2019 to January 2020; 100 children with a median age (IQR) of 5.4 years (4.8-7.3) were enrolled. All participants achieved protective RVNA titers on day 42 and 7-days post booster. Geometric mean titers (GMT) at day 42 were Group A, 8.98(95%CI 7.06-11.42); Group B, 23.89(95%CI 19.33-29.51); Group C, 9.94(95%CI 7.03-14.06). Likewise, RVNA GMT at 7 days post-booster were Group A, 42.53(95%CI 18.41-66.64); Group B, 23.19(95%CI 17.28-29.10); Group C, 57.75 (95%CI 35.86-79.67). CONCLUSIONS The 2-dose PrEP regimen of rabies vaccine produces adequate immune response either 0,7 or 0, 28 regimens.

Abstract
BACKGROUND Human coexistence with other animals can result in both intentional and unintentional contact with a variety of mammalian and non-mammalian species. International travellers are at risk for such encounters; travellers risk injury, infection and possibly death from domestic and wild animal bites, scratches, licks and other exposures. The aim of the present analysis was to understand the diversity and distribution of animal-related exposures among international travellers. METHODS Data from January 2007 through December 2018 from the GeoSentinel Surveillance Network were reviewed. Records were included if the exposure was non-migration travel with a diagnosis of an animal (dog, cat, monkey, snake or other) bite or other exposure (non-bite); records were excluded if the region of exposure was not ascertainable or if another, unrelated acute diagnosis was reported. RESULTS A total of 6470 animal exposures (bite or non-bite) were included. The majority (71%) occurred in Asia. Travellers to 167 countries had at least one report of an animal bite or non-bite exposure. The majority (76%) involved dogs, monkeys and cats, although a wide range of wild and domestic species were involved. Almost two-thirds (62.6%) of 4395 travellers with information available did not report a pretravel consultation with a healthcare provider. CONCLUSIONS Minimizing bites and other animal exposures requires education (particularly during pretravel consultations) and behavioral modification. These should be supplemented by the use of pre-exposure rabies vaccination for travellers to high-risk countries (especially to those with limited access to rabies immunoglobulin), as well as encouragement of timely (in-country) post-exposure prophylaxis for rabies and Macacine alphaherpesvirus 1 (herpesvirus B) when warranted.

Abstract
Since its reintroduction in 2015, rabies has been established as an enzootic disease among the dog population of Arequipa, Peru. Given the unknown rate of dog bites, the risk of human rabies transmission is concerning. Our objective was to estimate the rate of dog bites in the city and to identify factors associated with seeking health care in a medical facility for wound care and rabies prevention follow-up. To this end, we conducted a door-to-door survey with 4,370 adults in 21 urban and 21 peri-urban communities. We then analyzed associations between seeking health care following dog bites and various socioeconomic factors, stratifying by urban and peri-urban localities. We found a high annual rate of dog bites in peri-urban communities (12.4%), which was 2.6 times higher than that in urban areas (4.8%). Among those who were bitten, the percentage of people who sought medical treatment was almost twice as high in urban areas (39.1%) as in peri-urban areas (21.4%).

Abstract
BACKGROUND Reducing the number of doses required for pre-exposure prophylaxis (PrEP) would make it more feasible and cost-effective to implement in children at the highest risk of rabies exposure in Asia. We studied immune response of 2-site intradermal (ID) injection of rabies vaccine on days 0 and 28 for rabies PrEP simultaneously administrated with live-attenuated Japanese encephalitis chimeric virus vaccine (JE-CV) for children living in endemic area. RESEARCH DESIGN AND METHODS Seronegative children (n = 49) aged 12-16 months were randomized 2:1 into two groups: Group A subjects were vaccinated with 0.1-mL ID injection of purified Vero cell rabies vaccine (PVRV), each at two sites on day (D) 0 and D28; Group B subjects were vaccinated with conventional 0.5-mL intramuscular PVRV on D0, D7 and D28. Both groups received one dose of JE-CV subcutaneously on D0 and D365. Rabies virus neutralizing antibody (RVNA) titers were measured on D0, D42 and D365 after vaccination; Japanese Encephalitis (JE) neutralizing antibody titers were determined on D0, D42, D365 and D379. RESULTS All children had RVNA ≥ 0.5 IU/mL on D42 (geometric mean titers [GMTs] of RVNA 14.35 IU/mL [Group A] and 14.83 IU/mL [Group B], p > 0.05]). On D365, RVNA GMTs of subjects in group A and B were 1.50 IU/mL and 2.00 IU/mL (p > 0.05), respectively. All children had seroprotection following booster dose of JE-CV. There were no vaccine-related SAEs observed. CONCLUSION The 2-site ID PrEP with PVRV on days 0 and 28 co-administrated with JE-CV are safe and immunogenic.

Abstract
BACKGROUND World Health Organization changed the recommendation for pre-exposure rabies prophylaxis from 3-dose to 2-dose regimen in 2018. Given limited data of 2-dose regimens in pediatric population, this study aimed to compare the immunogenicity between 2-dose and 3-dose pre-exposure rabies immunization. METHODS This study was conducted among healthy children aged 2-12 years. They were randomized to 2-dose vaccination (2D) on days 0 and 28 or 3-dose vaccination (3D) on days 0, 7, and 28. Purified Vero cell rabies vaccine (PVRV-Verorab™) was administered intramuscularly. Rabies virus neutralizing antibody (RVNA) titers were measured at 3 time points: 14-day after complete vaccination, 1-year pre-booster vaccination, and 7-day post-booster dose to mimic scenario of rabies exposure. RVNA titers ≥0.5 IU/ml were considered adequate antibody. T cell specific response to rabies vaccine antigen was measured using the interferon-gamma enzyme linked immunospot assay. RESULTS From September to October 2017, 107 participants (51% males), 78 in 2D group and 29 in 3D group were enrolled. Median age was 5.8 years (IQR 4.4-7.3). All participants had RVNA titers ≥0.5 IU/ml after primary vaccination [GMT 2D: 18.6 (95%CI 15.9-21.8) and 3D: 16.3 (95%CI 13.2-20.1 IU/ml), p = 0.35]. At 1-year prior to receiving the booster, only 80% of the children in 2D group maintained RVNA titers ≥0.5 IU/ml compared to 100% of the children in 3D group (p = 0.01). However, all participants in both groups had RVNA ≥0.5 IU/ml at 7-day post booster vaccination [GMT 2D: 20.9 (95%CI 17.4-25.3) and 3D: 22.2 (95%CI 15.8-31.4) IU/ml (P = 0.75)]. The median number of IFN-γ secreting cells at 7-day post-booster dose was 98 and 128 SFCs per 106 PBMCs in the 2D and 3D groups, respectively (P = 0.30). CONCLUSIONS Two-dose primary rabies immunization provided adequate antibody at post primary vaccination and post booster. The results support 2-dose regimen of pre-exposure rabies immunization in the pediatric population.

Abstract
(1) Background: As part of the ongoing endeavor to eliminate dog-mediated human rabies in Thailand, renewed interest has been shown in oral vaccination of dogs as a supplementary tool to increase vaccination coverage of the dog population. (2) Methods: Three different bait types were tested using a hand-out model on the campus of the Kasetsart University and the surrounding temples in Thailand during September 2017, consisting of two industrial manufactured baits (fish meal and egg-flavored) and one bait made from local material (boiled pig intestine placed in collagen casing). A PVC-capsule containing dyed water was inserted in the bait. (3) Results: The fishmeal bait was significantly less often accepted and consumed (50.29%) than the other two baits (intestine bait—79.19%; egg bait—78.77%). Delivery and release of the dyed water in the oral cavity was highest in the egg-flavored bait (84.50%), followed by the intestine bait (76.61%) and fishmeal (54.85%) baits. Bait acceptance was influenced by sex, age, and body size of the dog. Also, the origin of the dogs had a significant effect: temple dogs accepted the baits more often than street dogs. (4) Conclusion: A significant portion of the free-roaming dog population in this study can be vaccinated by offering vaccine baits.

Abstract
PURPOSE OF REVIEW This review highlights current knowledge in travel-related neuroinfectious diseases, providing insight on approaches to prevention, diagnosis, and treatment of infections of the central nervous system (CNS) in travelers and immigrants. RECENT FINDINGS Updates on travel vaccine recommendations including vaccine-specific interactions with immunosuppressive agents, advances in Zika virus and dengue virus vaccine development, new diagnostic criteria for neurocysticercosis, updates on treatment approaches for tuberculosis meningitis. Increasing rates of travel are leading to the spread of known infectious diseases and the emergence of new diseases in travel medicine. Among these infections, neuroinfectious diseases carry significant morbidity and mortality. To reduce the effect of travel-related illness, appropriate pre-travel measures and up-to-date diagnostic and treatment strategies are essential for optimal outcomes. This review highlights important travel information relevant to neuroinfectious diseases for several populations including immunocompetent, immunocompromised, pregnant, and infant/children travelers. It also outlines the travel risk, clinical presentation, diagnosis, and management of a select list of neuroinfectious diseases by region, including neurocysticercosis, Zika virus, tuberculosis meningitis, rabies, and tick-borne encephalitis.

Abstract
BACKGROUND In canine rabies endemic countries the World Health Organization recommends post-exposure prophylaxis (PEP) be initiated immediately after exposure to an animal suspected to have rabies. Limited capacity in low and middle income countries to assess biting animals for rabies may result in the over prescription of rabies biologics. Few guidelines exist to determine the risk of whether a dog that has bitten someone is rabid. Given PEP cost and access limitations in many countries, accurate and timely assessment of dogs that have bitten people may reduce unwarranted PEP use and improve healthcare seeking behaviors. METHODS Haiti's animal rabies surveillance program utilizes veterinary professionals to conduct rabies assessments on reported biting dogs and records characteristics of the dog, health outcomes, and laboratory results in a national database. Characteristics of rabid dogs were assessed through a retrospective cohort study of biting dogs investigated during the period from January 2013⁻December 2015. 1409 biting dogs were analyzed; 1361 dogs that were determined to not have rabies were compared to 48 laboratory-confirmed rabid dogs. Rate ratios, sensitivity, specificity, positive predictive values, negative predictive values, likelihood ratios, quarantine survival of biting dogs, and a risk matrix were developed. FINDINGS The assessor's determination that the animal likely had rabies was the most significant predictive factor for a rabid dog (RR = 413.4, 95% CI 57.33⁻2985, Sn = 79.17, Sp = 91.92). Clinical factors significantly associated with rabid dogs included hypersalivation, paralysis, and lethargy (RR = 31.2, 19.7, 15.4, respectively). Rabid dogs were 23.2 times more likely to be found dead at the time of the investigation compared to case negative dogs (95% CI 14.0⁻38.6). Rabid dogs were also significantly more likely to lack a history of rabies vaccination or be unowned (RR = 10.3 95% CI 2.5⁻42.3 and RR = 4.5 95% CI 2.0⁻10.1, respectively). Rabid dogs were four times more likely to have bitten multiple people (RR = 4.0 95% CI 1.9⁻8.3). Most rabid dogs died or were killed before quarantine (75%) and all died by day 3 of quarantine, compared to <1% of quarantined case-negatives. The greatest risk of death was predicted to be for persons bitten on the head or neck from symptomatic dogs. Bites from dogs deemed healthy by veterinary assessors and which were available for quarantine presented less than a 0.05% risk of rabies death to the victim. CONCLUSIONS Vaccination of all persons exposed to a suspected rabid dog is a highly effective approach to minimize human rabies deaths. However, this may place undue financial burden on bite victims that have had a low-risk exposure and over-prescription may contribute to regional supply shortages. The results here indicate that in a low-resource country such as Haiti, a well-trained veterinary assessor can provide an accurate risk assessment of biting dogs based on a standard case investigation protocol. In canine rabies endemic countries with limited access to PEP, or where PEP costs may cause undue burden on bite victims, structured risk assessments by trained professionals may be a reliable method of triaging PEP for bite victims. Evaluating rabies risk through a matrix of bite location and risk factor in the dog presents a clear delineation of high and low risk encounters and should be used to develop data-derived PEP recommendations.

Abstract
Many vector-borne and zoonotic diseases are considered to be emerging; since they are either newly reported to cause human disease, or are causing disease in geographical locations or species not previously documented. In the past 15 years, significant outbreaks of Severe Acute Respiratory Syndrome (or SARS) and Middle Eastern Respiratory Syndrome (or MERS), Nipah and Hendra, Ebola virus disease and Zika fever and others have been reported. In this chapter the clinical characteristics, epidemiological aspects, treatment and prevention and information related to the laboratory investigation of important zoonotic and vector-borne diseases that have emerged in the past 10 years, and how this affects children, will be discussed. Furthermore rabies, considered a neglected viral disease with the majority of victims in Africa being children, will also be addressed.

Abstract
Background Rabies in China remains a public health problem. In 2014, nearly one thousand rabies-related deaths were reported while rabies geographic distribution has expanded for the recent years. This report used surveillance data to describe the epidemiological characteristics of human rabies in China including determining high-risk areas and seasonality to support national rabies prevention and control activities. Methods We analyzed the incidence and distribution of human rabies cases in mainland China using notifiable surveillance data from 1960–2014, which includes a detailed analysis of the recent years from 2004 to 2014. Results From 1960 to 2014, 120,913 human rabies cases were reported in mainland China. The highest number was recorded in 1981(0.7/100,000; 7037 cases), and in 2007(0.3/100,000; 3300 cases). A clear seasonal pattern has been observed with a peak in August (11.0% of total cases), Human rabies cases were reported in all provinces with a yearly average of 2198 from 1960 to 2014 in China, while the east and south regions were more seriously affected compared with other regions. From2004 to 2014, although the number of cases decreased by 65.2% since 2004 from 2651 to 924 cases, reported areas has paradoxically expanded from 162 prefectures to 200 prefectures and from southern to the central and northern provinces of China. Farmers accounted most of the cases (65.0%); 50–59 age group accounted for the highest proportion (20.5%), and cases are predominantly males with a male-to-female ratio of 2.4:1 on average. Conclusions Despite the overall steady decline of cases since the peak in 2007, the occurrence of cases in new areas and the spread trend were obvious in China in recent years. Further investigations and efforts are warranted in the areas have high rabies incidence to control rabies by interrupting transmission from dogs to humans and in the dog population. Furthermore, elimination of rabies should be eventually the ultimate goal for China. China is a high-risk environment for rabies, with human rabies cases second only to India globally. This paper reviews 55 years of rabies epidemiology in mainland China, and detailed analysis of data in recent years. In this study, notifiable surveillance data were analyzed and found that rabies still remains a serious public health problem in China, the east and south regions were more seriously affected compared with other regions, however, the occurrence of cases in new areas and the spread trend were obvious in China in recent years. Moreover, males in rural areas had higher risk of infection than residents in urban areas, a clear seasonal pattern has been observed with a peak in August. These findings indicated a clear need to increase government and public consciousness with regard to the potential risk of rabies and the means of avoiding the disease. Further efforts should be strengthen specially in the high spot areas.

Abstract
Community awareness regarding rabies and treatment seeking behaviours are critical both for the prevention and control of the disease in human and animals. We conducted a study to explore people's awareness about rabies, their attitudes towards dogs and practices associated with treating dog bites in Satkhira Sadar, a south-western sub-district of Bangladesh. Of the total 3200 households (HHs) surveyed, the majority of the respondents have heard about rabies (73%) and there was a high level of awareness that dog bite is the main cause of rabies (86%), and that rabies can be prevented by vaccination (85%). However, 59% of the dog bite victims first seek treatment from traditional healers instead of visiting the hospitals, 29% received the rabies vaccine, 2% practiced proper wound washing with soap and water, while 4.8% have not taken any measures. None of the victims have received rabies immunoglobulin (RIG). Of the respondents, 5.2% reported a history of dog bite in at least one family member, and 11.8% reported a history of dog bite in domestic animals during the previous year. The HHs having a higher number of family members (OR: 1.13, 95% CI: 1.07-1.2), having a pet dog (OR: 2.1, 95% CI: 1.4-3.2) and caring or feeding a community dog (OR: 2.1, 95% CI: 1.4-2.9) showed an increased risk of getting a dog bite. Among the bite victims, 3.6% (n = 6) humans and 15.8% (n = 60) animals died. As a measure for dog population management (DPM), 56% preferred sterilization while the rest preferred killing of dogs. The current treatment seeking behaviours of the respondents should be improved through additional education and awareness programme and better availability for the provision of post-exposure prophylaxis in Bangladesh. We recommend scaling up national mass dog vaccination and DPM to reduce the burden of rabies cases and dog bites in Bangladesh.

Abstract
BACKGROUND Rabies is an invariably fatal zoonotic viral disease. New Zealanders going abroad are largely unaware of the risk of contracting the disease. Prevention is the key to controlling the spread of this disease. METHODS Data from 363 individuals presenting to New Zealand travel health clinics between 1998 and 2012 for post-travel consultations on potential rabies exposure were collated retrospectively. The data focused on traveler demographics, the country and nature of exposure, the purpose of travel, and pre-travel rabies awareness. RESULTS The female-to-male ratio of subject travelers presenting was almost equal (1.1 : 1 ratio, respectively); the subjects were typically between 16 and 30 years (44.6%), tourists (64.5%), traveling less than 1 month (55.3%), and likely to have been exposed to animal contact in either Thailand (31.1%), China (13.2%), or Indonesia (12.3%). The animals to which they were exposed were usually dogs (59.5%) or monkeys (28.7%). Most potential exposures were penetrating (69.9%). Injury caused by the animal was more common in the lower limbs (50%) than in the upper limbs (43.4%); 89.4% of exposures were of World Health Organization (WHO) category III. Travelers were more likely to have received pre-travel rabies advice if they had been seen by a travel medicine specialist (96.1%) compared to a general practitioner (GP) (53.3%). Sixteen percent of travelers received rabies preexposure prophylaxis. Of the subjects who were managed following exposure, 79.7% did not receive immunoglobulin when indicated, and 21.5% did not receive any vaccine. Of the travelers that did receive a vaccine, 62.5% did so on the day of exposure. Of the travelers assessed, 16.7% had traveled without insurance. CONCLUSIONS New Zealanders require better guidance in understanding the need for travel-related rabies vaccination, as they are not managed abroad according to WHO guidelines. Few travelers had had pre-travel immunization, and only 20.3% of them had received WHO-advised postexposure management. Thus, 79.7% of the cohort theoretically remained at risk for contracting rabies because of inappropriate management following possible exposure to the disease.

Abstract
Rabies is one of the most feared human diseases as it is almost uniformly fatal once clinical symptoms set in. The majority of deaths were due to a lack of rabies post-exposure prophylaxis (PEP). We review the profile of travellers to Southeast Asia (SEA) seeking rabies PEP in Singapore General Hospital (SGH). Thirty-seven patients visited our travel clinic for rabies PEP from Dec 2010 to Dec 2013. Their mean age was 27.0 years. Twenty-four (65%) received rabies PEP within 24 hours of exposure. Rabies immunoglobulin (RIG) was indicated in 28 cases (76%) but only half were administered; two-thirds were given in our clinic. Only two received rabies pre-exposure prophylaxis and both were non-residents. There is an urgent need to increase the awareness of potential rabies infection amongst Asian travellers.

Abstract
OBJECTIVES This study aimed to describe for the first time the prevalence of the passively-reported rabies virus among different domestic and wild animals submitted to the Central Veterinary Laboratory from various areas in Yemen, and to study prevalence proportion ratios (PPR) that contributed to the spread of rabies among animals, and its transmission to humans. METHODS A brain sample was obtained from each of the 180 animals and tested for rabies virus by a direct fluorescent antibody test. RESULTS Out of the total number of animals involved in attacks on humans, 63.3 % were positive for rabies. Of these, dogs were the main animal involved in attacks with a percentage of 92%, of which 62.7% were positive for rabies. Of animals involved in attacks, 70.6% were males of which 60.6% were positive, and 29.4% were females of which 69.8% were positive. Males comprised 68.9% of the total human individuals attacked, of whom 62.9% were attacked by rabies-positive animals. The significant risk factors that contributed to the spread of rabies in general included the presence of poultry carcasses and other waste in the vicinity of the attacks (PPR = 9.5) with a percentage of 84.8%, followed by the time of year, in particular school vacations (PPR = 3.8) with a percentage of 78%. CONCLUSION Rabies is endemic in Yemen with a very high rabies-positive rate for animals involved in attacks, particularly for stray male dogs. Male children were most often involved in attacks by rabies-positive animals. The presence of food waste (particularly poultry carcasses) and school vacation periods were found to correlate significantly with increased risk for human exposure to rabies.

Abstract
Human dog-bite injuries are a major public health problem, particularly where there are large populations of free-roaming or street dogs. Dog bites are also the major source of human rabies infections. There is little information on the means to reduce these injuries. Monthly human animal-bite injury records from January 2003 to June 2011 were obtained from the main government hospital in Jaipur, India. The data were analysed and compared with records of pregnancy in street dogs in Jaipur obtained from a street dog sterilisation programme. Human animal-bite injuries showed a seasonal pattern which followed by approximately 10 weeks the seasonal peak of street dog breeding. The number of human animal bites has declined significantly since 2003. It is concluded that a street dog sterilisation programme can reduce human dog-bite injuries by reducing the maternal protective behaviour of the street dogs, as well as reducing the total size of the roaming dog population.

Abstract
Rabies is a major public health problem in Bangladesh, where most of the population live in rural areas. However, there is little epidemiological information on rabies in rural Bangladesh. This study was conducted in 30 upazilas (subdistricts) covering all six divisions of the country, to determine the levels of rabies and animal bites in Bangladesh. The total population of these upazilas was 6 992 302. A pretested questionnaire was used and data were collected by interviewing the adult members of families. We estimated that in Bangladesh, 166 590 [95% confidence interval (CI) 163 350-170 550] people per year are bitten by an animal. The annual incidence of rabies deaths in Bangladesh was estimated to be 1·40 (95% CI 1·05-1·78)/100 000 population. By extrapolating this, we estimated that 2100 (95% CI 1575-2670) people die annually from rabies in Bangladesh. More than three-quarters of rabies patients died at home. This community-based study provides new information on rabies epidemiology in Bangladesh.

Abstract
BACKGROUND Dog bites represent a significant health concern leading to a variety of consequences. Nursing students should be appropriately educated in order to manage and help prevent such injuries. AIM This paper is the first to report the lifetime experience and characteristics of dog bites among Greek nursing students and their knowledge in managing the above injuries. METHODS A cross-sectional quantitative study was performed using an anonymous questionnaire distributed to first and fourth year nursing students from April though June 2009. A knowledge score based on key questions was set on a scale from 0 to 7, to assess their competence on bite injuries management. RESULTS Of 237 nursing students recruited, 56 (23.6%) had experienced a dog bite. Men outnumbered women as dog bite victims [n = 15 (39.5%) vs. n = 41 (20.6%), P = 0.012]. Mean age at the attack was 11.1 (standard deviation = 5.6) years and legs sustained the majority of injuries (n = 31; 55.4%). Most bites (n = 39; 69.9%) involved a dog known to the victim, were provoked (n = 30; 53.6%) and occurred in a public place (n = 35; 62.5%). Ten (17.9%) of the victims sustained a moderate or severe injury. The majority (67.9%) of students answered correctly to less than or equal to three out of seven key knowledge questions. After multiple linear regression analysis, previous educational course attendance was the only factor associated with increased score (b = 0.48, standard deviation = 0.17, 95% confidence interval = 0.12-0.84, P = 0.009). CONCLUSIONS Dog bites were common and presented characteristic patterns among nursing students, but knowledge in their management was suboptimal. Improved education should be provided during undergraduate studies.

Abstract
BACKGROUND Dog bites in humans are a public health problem worldwide. The issues of increasing stray dog populations, rabies outbreaks, and the risk of dogs biting humans have been frequently reported by the media in Bhutan. This study aimed to estimate the bite incidence and identify the risk factors for dog bites in humans, and to estimate human deaths from rabies in rabies endemic south Bhutan. METHODS A hospital-based questionnaire survey was conducted during 2009-2010 among dog bites victims who visited three hospitals in Bhutan for anti-rabies vaccine injection. Decision tree modeling was used to estimate human deaths from rabies following dog bite injuries in two rabies endemic areas of south Bhutan. RESULTS Three hundred and twenty four dog bite victims were interviewed. The annual incidence of dog bites differed between the hospital catchment areas: 869.8 (95% CI: 722.8-1022.5), 293.8 (240-358.2) and 284.8 (251.2-323) per 100,000 people in Gelephu, Phuentsholing and Thimphu, respectively. Males (62%) were more at risk than females (P<0.001). Children aged 5-9 years were bitten more than other age groups. The majority of victims (71%) were bitten by stray dogs. No direct fatal injury was reported. In two hospital areas (Gelephu and Phuentsholing) in south Bhutan the annual incidence of death from rabies was 3.14 (95% CI: 1.57-6.29) per 100,000 population. The decision tree model predicted an equivalent annual incidence of 4.67 (95% CI: 2.53-7.53) deaths/100,000 population at risk. In the absence of post exposure prophylaxis, the model predicted 19.24 (95% CI: 13.69-25.14) deaths/year in these two areas. CONCLUSIONS Increased educational awareness of people about the risk of dog bites and rabies is necessary, particularly for children in rabies endemic areas of Bhutan.

Abstract
The aim of this study was to understand the use and distribution of human rabies post exposure prophylaxis (PEP) vaccine in Bhutan and to identify risk factors for receiving an incomplete course of the vaccine. We analyzed post exposure treatment records from 28 medical hospitals from 2005 to 2008. Males (59%) accounted for significantly more PEP events than females (41%) across all age groups (P<0.001). Children - particularly 5-9 years of age - received more rabies PEP than other age groups. Animal bite and non-bite accounted for 27% (n=2239) and 16% (n=1303) of rabies PEP, respectively, whilst 57% (n=4773) of the PEP events had no recorded information about the reasons for post exposure treatment. Post exposure treatment was provided throughout the year with a higher number during the winter and spring months. The number of PEP events significantly (P<0.001) increased between 2005 and 2008, from <1000 to >2800 events, respectively. Significantly (P<0.001) more PEP events were reported from the southern parts of Bhutan that are endemic for rabies or those areas in eastern Bhutan that have reported rabies outbreaks than other parts of Bhutan. Forty percent (n=3360) of the patients received an incomplete course of vaccine (<5-doses of vaccine intramuscular). Results suggest that patients with animal bite injury were less likely to receive an incomplete vaccine course than non-bite recipients, and patients presented to hospitals in rabies endemic or outbreak areas were less likely to receive an incomplete course than in non-rabies areas or rabies free areas. Similarly, patients presenting to hospitals for PEP during spring and summers months were less likely to receive an incomplete vaccine course than those during other seasons. Public education campaigns need to be conducted in Bhutan to reduce dog bite incidents and also to prevent mass exposures to rabies. A thorough assessment of each individual case based on the WHO guidelines would reduce unnecessary PEP (and therefore costs) in Bhutan.

Abstract
Epidemiological factors related to animal bites in humans and other animals were obtained from a database with 10,616 records of animal specimens sent for rabies diagnosis in northwest São Paulo State, Brazil, from 1993 to 2007. Of this total, 61.5% contained information on the bites, and among the biting animals (25%), the majority were dogs (67%), followed by cats (21.8%), and bats (8.1%). In 92.1% of the reports the victims were humans, and 82.3% of the animals were home pets. The majority of the biting dogs were less than a year old. There was a significant association (p < 0.0001) between aggressiveness and gender (with male animals more aggressive than females). Of the rabies-positive animals, 75.9% (183/241) were biters. The data are important for establishing bite prevention programs based on the profile of both victims and biting animals, besides identifying risk factors for animal bites.

Abstract
INTRODUCTION Dog attacks are a major public health concern worldwide. Dogs bite over 4 million people resulting in the hospitalization of 6000 to 13,000 people each year in the United States. Rarely deaths may occur after an attack. METHODS This study utilized the compressed mortality files from CDC WONDER to evaluate deaths from dog attacks over the 27-year period 1979-2005. RESULTS An average of approximately 19 deaths was reported annually from dog attacks during this time period. Males and children less than 10 years of age had the highest rate of death from dog attacks. Deaths have been reported in 49 states with Alaska reporting the highest death rate from dog attacks. The number of deaths and death rate from dog attacks appear to be increasing. CONCLUSIONS Deaths from dog attacks appear to be increasing as the population of both humans and dogs has increased during this time period. Children have the greatest risk of death. There is a need for a national reporting system on dog bites to fully capture the extent of fatalities and look at risk factors surrounding the attack. The development of effective prevention practices is dependent upon examination of these risk factors.

Abstract
Children have a high risk of exposure to rabies in countries where the disease is endemic. This prospective, 5-year study followed two groups of children who had received diphtheria, tetanus, whole-cell pertussis and inactivated poliomyelitis vaccine (DTP-IPV) at 2, 3, 4 months and 1 year (Group B) or concomitant with three doses of purified Vero cell rabies vaccine (PVRV), given at 2, 4 months and 1 year (Group A). Antibody determinations were made annually for 5 years. Data were available from a total of 72 subjects; 30 in Group A and 32 in Group B. In Group A, the percentage of patients immunized against rabies (anti-rabies > or = 0.5 IU/ml) decreased from 100% after the third vaccination to 63%, 5 years later. After 5 years, 93.8% in Group A and 96.7% in Group B had seroprotective diphtheria antibody titers > or = 0.01 IU/ml, and all subjects had anti-polio (type 1, 2 and 3) seroprotective titers > or = 5 1:dil. We conclude that co-administration of PVRV with DTP-IPV elicited protective antibody concentrations to all antigens that persist for at least 5 years, with continued protection against rabies in over 60% of subjects. These results are consistent with integration of pre-exposure rabies vaccination into the Expanded Program on Immunization (EPI) in countries where rabies is endemic.

Abstract
BACKGROUND Rabies is a fatal disease, and travelers going to endemic areas need to take precautions. Little is known about the rabies postexposure management of travelers from New Zealand. METHODS A total of 459 post-travel records from October 1998 until February 2006 at two travel medicine clinics, in Auckland and Hamilton, were examined for those who reported postexposure management to animals while abroad. RESULTS Fifty-four patients were included, 48 (88.9%) were New Zealand residents and 52.0% were male. The mean age of exposed travelers was 30.4 years (SD = 15.5). There was an adult to child ratio of 5:1. The highest exposure risk group was those aged 16 to 30 years. South and Southeast Asia were the most prominent geographical regions where exposure occurred, with 45 (83.3%) of subjects being potentially exposed to rabies. Dogs were the commonest animals involved, accounting for two thirds of incidents (36; 66.7%). The commonest sites of animal exposure on the body were the thigh and lower leg (26; 48.1%) and the hand (10; 18.5%). Forty-six (85.2%) of the animal exposures were graded as World Health Organization (WHO) category III. Forty-nine (90.7%) of the travelers had not had preexposure prophylaxis. Once in New Zealand, the correct WHO postexposure prophylaxis regime was applied on 44 of 52 (84.6%) occasions. However, overall, only 25% of the sample received postexposure treatment consistent with WHO guidelines, reflecting inappropriate management abroad. CONCLUSIONS Post-travel consultations at two New Zealand travel clinics were analyzed for prophylactic rabies postexposure management. The majority were travelers aged 16 to 30 years, who sustained WHO category III exposures to the lower limb in Asia, predominantly from dogs. Few of these travelers had been immunized prior to travel, and only 25% of them received postexposure prophylaxis consistent with WHO guidelines. Thus, 75% of the study sample remains at theoretical risk of contracting rabies due to inappropriate management overseas.

Abstract
BACKGROUND Skin disorders are common in travelers. Knowledge of the relative frequency of post-travel-related skin disorders, including their geographic and demographic risk factors, will allow for effective pre-travel counseling, as well as improved post-travel diagnosis and therapeutic intervention. METHODS We performed a retrospective study using anonymous patient demographic, clinical, and travel-related data from the GeoSentinel Surveillance Network clinics from January 1997 through February 2006. The characteristics of these travelers and their itineraries were analyzed using SAS 9.0 statistical software. RESULTS A skin-related diagnosis was reported for 4594 patients (18% of all patients seen in a GeoSentinel clinic after travel). The most common skin-related diagnoses were cutaneous larva migrans (CLM), insect bites including superinfected bites, skin abscess, and allergic reaction (38% of all diagnoses). Arthropod-related skin diseases accounted for 31% of all skin diagnoses. Ill travelers who visited countries in the Caribbean experienced the highest proportionate morbidity due to dermatologic conditions. Pediatric travelers had significantly more dog bites and CLM and fewer insect bites compared with their adult counterparts; geriatric travelers had proportionately more spotted fever and cellulitis. CONCLUSIONS Clinicians seeing patients post-travel should be alert to classic travel-related skin diseases such as CLM as well as more mundane entities such as pyodermas and allergic reactions. To prevent and manage skin-related morbidity during travel, international travelers should avoid direct contact with sand, soil, and animals and carry a travel kit including insect repellent, topical antifungals, and corticosteroids and, in the case of extended and/or remote travel, an oral antibiotic with ample coverage for pyogenic organisms.

Abstract
BACKGROUND To estimate the prevalence of dog bites to primary school children between the ages of 8-12 years using a semi-structured interview process. With the increase in the pet population and popularity of dangerous breeds of dog and a high stray dog population combined with a dearth of information on the risk of dog attacks to children in Trinidad, a semi-structured interview process was used to determine risk factors associated with dog attacks. METHODS A questionnaire survey of 1109 primary school children between the ages of 8-12 years was conducted in Trinidad from November 2002 to September 2003. The survey was conducted to determine the risk factors such as age, gender, size of dog and relationship of dog and victim, in dog bite incidents. The chi-square statistic and odds ratios were used to estimate risk factors for a bite incident. RESULTS Twenty-eight percent of children were bitten at least once by a dog. Gender (male) and owning a dog were statistically significant risk factors (p = 0.003 and 0.008 respectively, chi2 df, 95% confidence). Most attacks occurred outside of the home (58.0%) followed by the victims' home (42.0%) and were by a dog known but not owned (54.6%) by the victim. Many victims (33.0%) were bitten without having any interaction with the dog and the majority (61.9%) of victims did not receive professional medical assistance. Overall, the lower leg or foot was most often injured (39.3%). CONCLUSION A public educational campaign is needed on responsible pet ownership. In addition, children must be taught effective ways of avoiding attacks or reducing injury in the event of a dog attack. The Dangerous dogs Act 2000 must be proclaimed in parliament by the Government of Trinidad and Tobago to exert more pressure on pet owners to safeguard the public from the menace of dog attacks.

Abstract
As a direct consequence of the current increase in international mobility, a significant increase in family travel is occurring. Protection against vaccine preventable diseases in the travelling child plays a key role both from an individual and a public health perspective: pre-travel immunisation protects travelling children and, at the same time, prevents the importation of pathogens that can spread throughout the community. Children immunisation presents unique challenges in travel medicine practice: some vaccines cannot be given below a definite age for several reasons and altering the standard schedule of routine vaccines is sometimes needed to ensure early protection. Furthermore, the risk for some travel-related diseases is higher among children. The aim of this review is to analyse the main epidemiological and clinical aspects relevant to immunisation of travelling children and to provide travel medicine practitioners with a practical approach to this issue.
