Abstract
Water plays a vital role as a natural resource since life is unsustainable without it. If water is polluted or contaminated, it results in several health issues among people. Millions of people are infected with waterborne diseases globally, and India is no exception. In the present review, we have analyzed the outbreaks of waterborne diseases that occurred in several Indian states between 2014 and 2020, identified the key infections, and provided insights into the performance of sanitation improvement programs. We noted that acute diarrheal disease (ADD), typhoid, cholera, hepatitis, and shigellosis are common waterborne diseases in India. These diseases have caused about 11,728 deaths between 2014 and 2018 out of which 10,738 deaths occurred only after 2017. The outbreaks of these diseases have been rising because of a lack of adequate sanitation, poor hygiene, and the absence of proper disposal systems. Despite various efforts by the government such as awareness campaigns, guidance on diet for infected individuals, and sanitation improvement programs, the situation is still grim. Disease hotspots and risk factors must be identified, water, sanitation, and hygiene (WASH) services must be improved, and ongoing policies must be effectively implemented to improve the situation. The efforts must be customized to the local environment. In addition, the possible effects of climate change must be projected, and strategies must be accordingly optimized.

Abstract
This scientific review paper explores international and country-specific healthcare guidelines for non-communicable diseases with the highest burden among individuals aged 75 years and above. The study aims to identify the best vaccination practices and standardize healthcare practices to improve vaccination adherence in this vulnerable population. Given that older people are more prone to infectious illnesses and have higher rates of morbidity and mortality, vaccinations are essential for disease prevention. Despite the proven efficacy of vaccinations, adherence has plateaued in recent years, partly due to a lack of accessibility, public education, and variability in disease-specific guidelines. This paper highlights the need for a more robust and standardized international vaccination model to improve quality of life and reduce disability-adjusted life years among the elderly. The findings of this study call for further research to review the guidelines as more implementations are put in place, including non-English guidelines.

Abstract
BACKGROUND Health Care workers (HCWs) have an approximate four-fold increased risk of contracting hepatitis B infection than the normal population. A lack of knowledge and practices regarding precautions has been frequently observed. We aimed to do a knowledge, attitude, and practices (KAP) study regarding hepatitis B prevention measures among HCWs. METHODS The study enrolled 250 HCWs. A questionnaire-based proforma regarding KAP towards hepatitis B, its causation, and prevention was filled out by each participant. RESULTS Mean age (SD) of participants was 31.8 ± 9.1 years with 83 males and 167 females. Subjects were divided into two groups: Group I (House Surgeons and Residents) and Group II (Nursing staff, Laboratory Technicians, Operation Theatre Assistants). All Group I and 148 (96.7%) of Group II subjects had adequate knowledge regarding the professional risk of hepatitis B virus transmission. Knowledge regarding different modes of transmission was less in Group II subjects (Blood (96.1%), Sex (84.3%), percutaneous route (85.6%), and During Birth (83%)) as compared to Group I (100% in all). All subjects in Group I and 134 (90.9%) Group II subjects knew about vaccination as a preventive measure. There was a slight discordance between attitude and practices towards universal precautionary measures in Group II subjects (Use of gloves 96.1% vs 94.8%; Safe needle disposal 96.7% vs 96.1%; Vaccination 94.8% vs 67.9%). Of the subjects in Group I, 94.8% were vaccinated and 67.9% were vaccinated in Group II, with complete vaccination rates being 76.3% and 43.1%, respectively, and the difference was statistically significant (P < 0.001). CONCLUSION Better knowledge and attitude led to more adoption of preventive practices. But, still, there is a gap in the KAP towards hepatitis B preventive practices and knowledge is not getting transformed into practices. We recommend that all HCWs should be questioned about their vaccination status. In addition, vaccination coverage, various preventive campaigns, and the hospital infection control committee (HICC) need to be strengthened.

Abstract
Viral hepatitis is a major public health problem affecting children globally. Clinical presentation varies from asymptomatic illness to hepatitis, and liver failure. Data on clinical features and laboratory parameters were collected and analysed on 300 children, aged 1-12 years, admitted with confirmed viral hepatitis. A small majority (52%) were boys. The mean age of presentation was 6.9 ± 2.8 years with the commonest symptoms being anorexia or vomiting (in 98%), fever (in 89%) and jaundice (in 71.3%). Tender hepatomegaly was seen in 31.7%. Almost all (97.6%) had hepatitis A, though mixed infection (A & E) was seen in 1.7%. Only 8% had serum bilirubin levels >200 µmol/L. Significantly elevated (>20 μkat/L) levels of aspartate transaminase and alanine transaminase were seen in 19% and 25.3% of cases respectively. Coagulopathy (PT >15 s) was present in 11.0% cases. HAV remains the most common cause of viral hepatitis in children in our environment. Public awareness and universal vaccination should be the focus to prevent morbidity and mortality due to these pathogens.

Abstract
AIMS The objective of this study was to compare diagnostic accuracy of elastography point quantification (ElastPQ) with transient elastography (TE) and liver histology for measuring liver stiffness in patients with chronic viral hepatitis (CVH) and nonalcoholic fatty liver disease (NAFLD). METHODS Thirty-two patients with chronic liver disease (CVH and NAFLD) were evaluated by ElastPQ and TE within 7 days of liver biopsy. Within the CVH group, subgroup analysis was carried out in patients with end-stage renal disease (ESRD) and without ESRD. Area under the receiver operating characteristic (AUROC) curves were calculated for ElastPQ and TE. RESULTS There were 15 patients with CVH and 17 patients with NAFLD. In the CVH group, there were 8 patients with ESRD and 7 patients without ESRD. Taking liver histopathology as the gold standard, liver stiffness measurement by ElastPQ (ρ = 0.826;P < 0.0001) and TE (ρ = 0.649; P < 0.0001) correlated significantly with the stage of fibrosis. AUROCs of ElastPQ and TE for the diagnosis of any fibrosis (F ≥ 1), significant fibrosis (F ≥ 2), and advanced fibrosis (F ≥ 3) were 0.907, 0.959, 0.926 and 0.870, 0.770, 0.881, respectively, in both CVH and NAFLD groups. However, the accuracy of both these techniques was poor in patients with CVH and ESRD (AUROCs for ElastPQ and TE of 0.667 and 0.167 for the diagnosis of significant fibrosis, respectively, and 0.429 and 0.143 for the diagnosis of advanced fibrosis, respectively). The diagnostic accuracy of both ElastPQ and TE for detecting significant fibrosis was excellent in patients with NAFLD (AUROC of 1.000 and 0.936, respectively). ElastPQ was superior to TE in the diagnosis of significant fibrosis in the combined analysis (P = 0.0149) and in the CVH group (P = 0.0391), while both modalities were comparable in patients of the NAFLD group (P = 0.2539). CONCLUSION ElastPQ may be equally accurate as Fibroscan, and large prospective studies are required to validate the same.

Antibody avidity-based approach to estimate population-level incidence of hepatitis C. J Hepatol 2020; 73:294-302.

Abstract
BACKGROUND & AIMS Accurate HCV incidence estimates are critical for monitoring progress towards HCV elimination goals, including an 80% reduction in HCV incidence by 2030. Moreover, incidence estimates can help guide prevention and treatment programming, particularly in the context of the US opioid epidemic. METHODS An inexpensive, Genedia-based HCV IgG antibody avidity assay was evaluated as a platform to estimate cross-sectional, population-level primary HCV incidence using 1,840 HCV antibody and RNA-positive samples from 875 individuals enrolled in 5 cohort studies in the US and India. Using samples collected <2 years following HCV seroconversion, the mean duration of recent infection (MDRI) was calculated by fitting a maximum likelihood binomial regression model to the probability of appearing recent. Among samples collected ≥2 years post-HCV seroconversion, an individual-level false recent ratio (FRR) was calculated by estimating the probability of appearing recent using an exact binomial test. Factors associated with falsely appearing recent among samples collected ≥2 years post seroconversion were determined by Poisson regression with generalized estimating equations and robust variance estimators. RESULTS An avidity index cut-off of <40% resulted in an MDRI of 113 days (95% CI 84-146), and FRRs of 0.4% (95% CI 0.0-1.2), 4.6% (95% CI 2.2-8.3), and 9.5% (95% CI 3.6-19.6) among individuals who were HIV-uninfected, HIV-infected, and HIV-infected with a CD4 count <200/μl, respectively. No variation was seen between HCV genotypes 1 and 3. In hypothetical scenarios of high-risk settings, a sample size of <1,000 individuals could reliably estimate primary HCV incidence. CONCLUSIONS This cross-sectional approach can estimate primary HCV incidence for the most common genotypes. This tool can serve as a valuable resource for program and policy planners seeking to monitor and reduce HCV burden. LAY SUMMARY Determining the rate of new hepatitis C virus (HCV) infections in a population is critical to monitoring progress toward HCV elimination and to appropriately guide control efforts. However, since HCV infections are most often initially asymptomatic, it is difficult to estimate the rate of new HCV infections without following HCV-uninfected people over time and repeatedly testing them for HCV infection. Here, we present a novel, resource-efficient method to estimate the rate of new HCV infections in a population using data from a single timepoint.

Abstract
BACKGROUND Although hepatitis B vaccinations have been integrated in the Universal Immunization Program (UIP) in India over a decade, only half of the children are immunized against hepatitis B. The national average in hepatitis B vaccination conceals large variations across states, districts and socio-economic groups. In this context, the aim of this paper is to examine the spatial heterogeneity and contextual determinants of hepatitis B vaccination across the districts of India. METHODS Using data of 199,899 children aged 12-59 months from the National Family Health Survey-4 (NFHS-4), 2015-16 we have examined the district level spatial distribution and clustering of hepatitis B vaccination with the help of Moran's I and Local Indicator of Spatial Autocorrelation (LISA) measures. We investigated the low coverage of HBV vaccination using spatial autoregressive models (SAR) at the meso scale. And we applied multivariate binary logistic regression analysis to understand the micro-level predictors of hepatitis B vaccination. RESULTS In 2015-16, 45% of the children aged 12-59 months were not vaccinated against hepatitis B in India. The coverage of hepatitis B vaccine across the districts of India showed a highly significant spatial dependence (Moran's I = 0.580). Bivariate Moran's I confirmed the spatial clustering of hepatitis B vaccination with mother's education, full antenatal care (ANC) utilization, post natal care (PNC) utilization, institutional births and registration of births at the district level. Districts with a very low coverage of HBV vaccine are clustered in the western, north-eastern regions and in some parts of central India. At the unit (child) level, children's hepatitis B immunization status is mostly determined by the socio-economic and demographic characteristics like their mother's educational status, caste, religion, household's wealth condition, birth order, year of birth and the region they belong to. CONCLUSIONS District level variation in hepatitis B vaccination is spatially heterogeneous and clustered in India with a strong neighbourhood effect. Uptake of hepatitis B vaccine among Indian children is predominantly dependent upon their socio-economic and demographic characteristics.

Abstract
Purpose The major cause of chronic hepatitis is infections with hepatitis B virus and hepatitis C virus (HCV) globally. However, there exists sparse epidemiological data regarding the prevalence of HCV infection from India. Methodology We carried out a cross-sectional study to estimate the prevalence of anti-HCV antibody among acute febrile illness cases aged between 1 and 65 years in Idar Taluk, Sabarkantha district, Gujarat state located in West India. A total of 702 serum samples collected from the study area during the year 2017, were screened for anti-hepatitis C IgG by enzyme-linked immunosorbent assay. The serum samples screened positive were then subjected to molecular testing for confirmation. Results Among the 702 study participants screened, 16 cases were reported to be anti-HCV IgG positive with an estimated seroprevalence rate of 2.3% (95% confidence interval: 1.4%-3.7%). Out of the 16 cases, two samples were confirmed positive by molecular testing indicating active infection. When analysed phylogenetically, one strain was genotyped as HCV1b genotype, and the other one was clustered along with HCV3a genotype. Both the patients with hepatitis C infection were observed to be having a probable 1-year survival rate of 100% and a 2-year survival rate of 85% when the Child-Turcotte-Pugh classification was applied. Conclusion The estimated seroprevalence of hepatitis C in Idar Taluk, Sabarkantha district, west India was 2.3%. HCV genotypes 1b and 3a were observed to be circulating in the study area.

Objective of this study was to analyze such outbreaks and to explore hypothesis pertaining the transmission mode. Methods Retrospective observational study involving cases of acute hepatitis B acquired between 1 January 2015 and 31 December 2015 and their family members residing in Mazhuvanoor village in Ernakulam district of Kerala State in southern India. Results 59 houses were included in the survey. The number of patients diagnosed to have acute viral hepatitis B was 59. Majority (66.10%) were over 50 years old. There were no cases below the age of 15 years. All 59 patients claimed to have been bitten frequently by a fly which was identified as “deer fly” belonging to the genus Chrysops. Conclusion Given the current understanding of mechanical transmission of pathogens in both humans and animals by insects belonging to the Tabanidae family which also includes Chrysops, it is plausible that the same mechanism may hold true for hepatitis B also. However this needs to be proven in further studies both at the laboratory level and at field studies.

Abstract
The study aimed to determine the prevalence of occult hepatitis B virus infection among HIV-infected persons and to evaluate the use of a pooling strategy to detect occult HBV infection in the setting of HIV infection. Five hundred and two HIV-positive individuals were tested for HBV, occult HBV and hepatitis C and D with serologic and nucleic acid testing (NAT). We also evaluated a pooled NAT strategy for screening occult HBV infection among the HIV-positive individuals. The prevalence of HBV infection among HIV-positive individuals was 32 (6.4%), and occult HBV prevalence was 10%. The pooling HBV NAT had a sensitivity of 66.7% and specificity of 100%, compared to HBV DNA NAT of individual samples. In conclusion, this study found a high prevalence of occult HBV infection among our HIV-infected population. We also demonstrated that pooled HBV NAT is highly specific, moderately sensitive and cost-effective. As conventional HBV viral load assays are expensive in resource-limited settings such as India, pooled HBV DNA NAT might be a good way for detecting occult HBV infection and will reduce HBV-associated complications.

Abstract
Most cases of chronic hepatitis E virus (HEV) infection in solid organ transplant recipients are attributable to genotype 3. Although India is hyperendemic for HEV genotype 1, chronic infection in transplant patients has not been reported. In this study, 30 liver transplant recipients were followed up by systematic testing for various markers of HEV (IgM, IgG, HEV-Ag, and RNA) on blood and stool samples obtained pre-transplant, and then at 3 and 6 months post-transplant to look for HEV exposure and persistence. Evidence of HEV infection was found in 6 (20%) cases post-transplant but none of the recipients demonstrated active viremia or antigenemia. This suggests that the circulating genotype of HEV in our population might have limited potential to cause chronic infections.

Abstract
BACKGROUND Polymorphisms of the IL28B gene (rs12979860 and rs8099917) have been shown to impact treatment responses in hepatitis C virus (HCV) infected patients. The association of these polymorphisms with sustained viral response (SVR) has been studied in HCV genotype 3 infected patients in India, but not in genotype 1. OBJECTIVES This study aimed to determine the association of IL28B gene polymorphisms and other host and viral factors with treatment response in patients with HCV genotype 1 and 3 infection. MATERIALS AND METHODS DNA from 42 HCV-infected patients on antiviral therapy was analysed for the IL28B polymorphisms using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Bidirectional sequencing was performed on a subset of samples for verification of PCR-RFLP results. Information on age, weight, height, diabetic status, pre-treatment viral load and alanine aminotransferase (ALT) levels was obtained from clinical records. The IL28B genotypes and the other factors were analysed for their association with SVR. RESULTS The frequency distribution of rs12979860 CC/CT/TT genotypes was found to be 66.7%, 26.2% and 7.1%, respectively. For rs8099917 genotype, the TT/GT/GG distribution was 73.8%, 21.4% and 4.8%, respectively. SVR was seen in 61.9% of cases (55.6% in genotype 1 and 62.5% in genotype 3). CC genotype at rs12979860 and TT genotype at rs8099917 were significantly higher in responders (P = 0.013 and 0.042, respectively). Lower baseline ALT and rapid viral response were also found to be associated with SVR. On logistic regression analysis, CC genotype at rs12979860 emerged as the most powerful predictor of treatment response. CONCLUSION IL28B polymorphisms are strong predictors of SVR in patients from the Indian subcontinent infected with HCV genotype 3 and genotype 1.

Abstract
Background - Hepatitis B virus and hepatitis C virus are among the principal causes of severe liver disease. There is limited data of epidemiology of Hepatitis B in community, more so in rural population. Objective - To find the prevalence of hepatitis B and C infection in community and study the risk factors for their transmission. Methods - This was a community based cross sectional study. A total of 1833 randomly selected subjects from a rural area were interviewed for risk factors for transmission and tested for markers of hepatitis B and hepatitis C infection. All the positive card tests were confirmed by ELISA. Results - Out of 2400 subjects, rate for participation was 76.38%. None of the subjects was positive for anti hepatitis C virus antibody. Point prevalence for HBsAg positivity was 0.92. Being healthcare worker and having tattoo were significantly associated with HBsAg positive results. Nose and ear piercing was reported by almost. History of blood or blood product transfusion, I/V drug abuse, multiple sexual partners, unsafe Injections, hemodialysis and any h/o surgery was not associated with HBsAg positivity. Conclusion - Health care workers are at high risk for transmission of hepatitis B. Educating common people regarding mode of transmission of Hepatitis B and C will help to reduce their transmission.

Abstract
Although only a single serotype of hepatitis E virus (HEV), the causative agent of hepatitis E, has been identified, there is great genetic variation among the different HEV isolates reported. There are at least four major recognized genotypes of HEV: genotypes 1 and 2 are mainly restricted to humans and linked to epidemic outbreaks in nonindustrialized countries, whereas genotypes 3 and 4 are zoonotic in both developing and industrialized countries. Besides human strains, genotype 3 and 4 strains of HEV have been genetically characterized from swine, sika deer, mongooses, sheep, and rabbits. Currently, there are approximately 11,000 human and animal sequences of HEV available at the International Nucleotide Sequence Database Collaboration. HEV is the major cause of waterborne outbreaks of hepatitis in areas of poor sanitation. Additionally, it is responsible for sporadic cases of viral hepatitis in not only endemic but industrialized countries as well. Transmission of HEV occurs predominantly by the fecal-oral route, although parenteral and perinatal routes have been reported. HEV infection develops in most individuals as a self-limiting, acute, icteric hepatitis; with mortality rates around 1%. However, some affected individuals will develop fulminant hepatic failure, a serious condition that is frequently fatal without a liver transplant. This complication is particularly common when the infection occurs in pregnant women, where mortality rates rise dramatically to up to 25%. Among the preventive measures available to avoid HEV infection, two separate subunit vaccines containing recombinant truncated capsid proteins of HEV have been shown to be highly effective in the prevention of disease. One of them, HEV 239, was approved in China, and its commercialization by Innovax began in November 2012 under the name Hecolin(®).

Abstract
This prospective study was designed to evaluate whether early changes in actin-free Gc-globulin levels were associated with complications and outcomes and to identify factors associated with persistent low actin-free Gc-globulin levels in acute liver failure (ALF). Thirty-two consecutive ALF patients admitted from October 2011 to December 2012 were followed up until death or complete recovery. All had serum actin-free Gc-globulin estimation at admission and at day three or expiry. Logistic regression analysis was performed to identify independent predictors of mortality. A receiver operating characteristic curve analysis was also performed. Nonsurvivors had significantly lower median actin-free Gc-globulin levels than survivors (87.32 vs 180 mg/L; P < 0.001). A receiver operating characteristic curve analysis revealed an area under curve (AUC) of 0.771 and showed that serum actin-free Gc-globulin level of ≤124 mg/L would predict mortality with 92% sensitivity and 71.4% specificity. Patients with lower serum actin-free Gc-globulin levels and decreasing trend in serum actin-free Gc-globulin levels were found to have more mortality and developed more complications. Logistic regression analysis showed that serum actin-free Gc-globulin, total leucocyte count and serum creatinine at admission were independent predictors of mortality. Incorporating these variables, a score predicting mortality risk at admission was derived. The scoring system was compared to MELD score and King's College Criteria as individual predictor of mortality. Serum actin-free Gc-globulin level at presentation is predictive of outcome and can be used for risk stratification. Its persistent low-level predicts mortality and is correlated with various complications.

Abstract
Globally, approximately 240 people have been infected worldwide with hepatitis B Virus (HBV). India has approximately HBV carrier rate of 3.0% with a high prevalence rate in the tribal population. With a population of more than 1.25 billion, India has more than 37 million HBV carriers and contributes a large proportion of this HBV burden. While horizontal transmission in childhood appears to be a major route of transmission, the role of vertical transmission is probably underestimated. Blood transfusion and unsafe therapeutic injections continue to be important modes of transmission of HBV. There is a need for large field studies to better understand HBV epidemiology and identify high prevalence areas, and public health measures to prevent disease transmission and decrease the burden of the disease.

Abstract
Background: Pregnant women are at increased risk of complications in hepatitis E virus (HEV) infection, with the risk increasing as the pregnancy progresses, often leading to fulminant hepatic failure and adverse fetal outcome. Aims: The primary objective of the following study is to evaluate the maternal and fetal complications of this infection and secondary aim is to compare the clinical features of hepatitis E in pregnant women to those in non-pregnant women. Subjects and Methods: This was a hospital based case-controls study, carried out from July 2008 to June 2010. Over a period of 2 years, cases were serologically confirmed pregnant women with hepatitis E, selected by screening in antenatal clinic. Controls were serologically confirmed non-pregnant women with hepatitis E, selected by screening in Medicine Outpatient Department. We studied 96 women with HEV infection, of which 52 were pregnant and 44 were non-pregnant. Clinical and laboratory profile of patients in both groups were studied. Patients were treated as per protocol and the outcome was studied in both groups. Pregnant women were followed-up for fetal and maternal outcome. We used t-test and z-test to compare normally distributed data and non-normally distributed data, respectively. Chi-square test was used to compare discrete values between groups. Results: Mean (standard deviation [SD]) age in pregnant patients was 24.1 (3.3) years while 32.6 (10.5) years in non-pregnant patients. 71.1% (37/52) of the patients were primigravida and 28.8% (15/52) patients were multigravida, by natural occurrence. Mean (SD) gestational age when infection occurred was 27.5 (7.2) weeks. Among pregnant women, 63.4% (33/52) were in 3rd trimester. Jaundice 1-5 days before presentation was seen in 51.9% (27/52) pregnant and 44.2% (23/44) non-pregnant women. Myalgia/arthralgia, fever, nausea/vomiting, right upper quadrant pain, jaundice, dark urine, light-colored stools, pruritus, diarrhea, altered sensorium and hematemesis/melena were presenting features. In pregnant group, 46.1% (24/52) patients developed encephalopathy while in non-pregnant group 34% (15/44) developed this complication. Among pregnant cases, 67.3% (35/52) survived and 32% (17/52) cases died. In non-pregnant group, nearly 90% (40/44) patients survived and only 9% (4/44) patients died. This difference was statistically significant (P < 0.01). Adverse fetal outcome was seen in 71.1% (37/52) pregnant women with acute hepatitis E, including pre-term delivery in 23% (12/52), stillbirth in 23% (12/52), abortion in 3.8% (2/52) and intra-uterine fetal death in 21.1% (11/52) patients. Conclusions: There is significantly higher occurrence of hepatitis E infection in pregnant women than in non-pregnant women, which increases with gestation, with associated fulminant hepatic failure, maternal mortality and worse fetal outcome.

Abstract
The aim of the study was to assess the blood safety in India through prevalence in thalassaemic population. Safety of the blood supply is a subject of great concern for all recipients. This review attempts to assess the relevance and format of tests for viruses in the context of transfusion transmitted infection (TTI) prevalence in India. Serological marker testing for human immunodeficiency virus-1/2 (HIV-1/2), hepatitis C virus (HCV) and hepatitis B virus (HBV) is mandatory in India. Numerous TTI incidents in the repeat recipients supported by results from nucleic acid technology (NAT) testing indicate the deficiencies in blood safety. The β-thalassaemic population (3-17%) in India has been used to reflect on blood safety. The prevalence of HIV-1/2, HCV and HBV in the Indian donor population, the limitations in accessing safe donors, quality of serological tests and the impact on repeat recipients is evaluated. The reports point to prevalence of ˜2% of viral diseases in the blood donor population, and the insufficiency of serology testing resulting in up to 45% TTIs in thalassaemics. The revelation by individual donation (ID) NAT testing, of 1 per 310 units being serology negative-NAT reactive is alarming. Extrapolating the serology negative NAT reactive yields, for an annual blood supply of 7.9 million units, 23,700 units or nearly 100,000 blood components are likely to be infectious. Though the cost for ID-NAT testing is considered unaffordable for a medium development country such as India, the enormity of TTIs will place an unmanageable cost burden on the society.

Abstract
The likelihood of developing chronic hepatitis B infection and its complications is most when infection is transmitted vertically. Awareness of the current recommendations for managing babies of mothers who are hepatitis B carriers is not universal, resulting in failure of follow up, despite the serious long term implications, including development of hepatic carcinoma. We review the current guidelines of managing babies born to mothers who are hepatitis B carriers.

Abstract
BACKGROUND Recently, strategic planning was initiated by the National Blood Transfusion Services Pakistan to improve its blood bank facilities. Emphasis has been placed on appropriate screening of blood products. Located in the southern region, Aga Khan University Hospital is a 700-bed tertiary care academic institute with comprehensive blood banking. Screening of blood donors has been based on verbal screening and serologic testing to date. Additionally, the need of implementing nucleic acid testing (NAT) was considered in 2011 because of an upsurge in hepatitis epidemiology. The aim of this study was to analyze the efficacy of this additional donor screening program and to evaluate the impact of NAT on the yield and residual risk of transfusion-transmissible viral infections. STUDY DESIGN AND METHODS A total of 42,830 blood donations collected between 2011 and 2012 were screened for routine serologic assays. Only serologically negative donors (n=41,304) were tested for NAT. The frequency of viral infections was evaluated through serologic techniques and NAT yield for viral agents was estimated for computing window period donors. Residual risk per million donors was computed for viral infections in seronegative blood donors. RESULTS Serologic work-up showed 1571 abnormal screening results in 1526 blood donors with the following results: hepatitis C virus antibodies (anti-HCV; n=708), hepatitis B surface antigen (n=555), human immunodeficiency virus antibodies (anti-HIV; n=29), malaria (n=30), VDRL (n=249), and coinfection (n=45). Thirty-five NAT-reactive samples were identified: HIV-1, one; HCV, 27; and hepatitis B virus (HBV), seven. Incident rates per 10(5) donors were highest for HCV (453.3) followed by HBV (171.5) and HIV (72.2). Calculated residual risk per million donors was highest at 1 in 10,900 for HBV, intermediate at 1 in 13,900 for HCV, and least at 1 in 62,600 for HIV. CONCLUSION Incidence rates and estimated residual risk indicate that the current risk of transfusion-transmitted viral infections attributable to blood donation is relatively high in this country. The study recommends the parallel use of both serology and NAT screening of donated blood in countries that have high seroprevalence of these viral infections.
