Abstract
Several hepatitis A outbreaks have recently been reported in Kerala state, India. To inform coverage decision of hepatitis A vaccine in Kerala, this study aimed to examine the cost-effectiveness of 1) hepatitis A vaccination among children aged 1 year and individuals aged 15 years, and 2) serological screening of individuals aged 15 years and vaccination of susceptible as compared to no vaccination or vaccination without serological screening. Both live attenuated hepatitis A vaccine and inactivated hepatitis A vaccine were considered in the analysis. A combination of decision tree and Markov models with a cycle length of one year was employed to estimate costs and benefits of different vaccination strategies. Analysis were based on both societal and payer perspectives. The lifetime costs and outcomes were discounted by 3%. Our findings indicated that all strategies were cost-saving for both societal and payer perspectives. Moreover, budget impact analysis revealed that vaccination without screening among individuals aged 15 years could save the government's budget by reducing treatment cost of hepatitis A. Our cost-effectiveness evidence supports the inclusion of hepatitis A vaccination into the vaccination program for children aged 1 year and individuals aged 15 years in Kerala state, India.

Rising trend of symptomatic infections due to Hepatitis A virus infection in adolescent and adult age group: An observational study from a tertiary care liver institute in India. Indian J Med Microbiol 2024; 50:100653. [PMID: 38906330 DOI: 10.1016/j.ijmmb.2024.100653] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Revised: 05/27/2024] [Accepted: 06/19/2024] [Indexed: 06/23/2024]
Abstract
BACKGROUND Hepatitis A Virus (HAV) is the most common cause of Acute Viral Hepatitis (AVH) in children. It causes self-limiting illness and rarely acute liver failure. The shifting pattern in HAV endemicity is rendering adolescents and adults vulnerable to infection. METHODS In this retrospective study, samples received from 14,807 patients with acute onset icteric illness from January 2014-December 2022 were analyzed. HAV infection was detected by anti-HAV IgM positivity. The cases were divided into 3 age groups, pediatric, adolescents and adults, and clinical presentations were compared. RESULTS Overall, 7.72%(1144) were positive for anti-HAV IgM. Of these, 60%(690) were finally included in the study. The positive cases were divided into adults, ≥18 years (44%, 304); pediatric, <12 years (31%, 212) and adolescents (25%,174) age groups. Overall males were predominant [72.4%(500)], with a median age of 16 (IQR:9-21) years. Cases were characterised into AVH (68.1%, 470/690), Acute Liver Failure (ALF) (31.4%, 217/690) and Acute-on-Chronic Liver Failure (0.43%, 3/690). AVH in the pediatric age group was 69%(146/212), adolescents was 67%(117/174), and adults was 68%(207/304). ALF cases among the 3 groups were 30%(65/212), 33%(57/174), and 31%(95/304) respectively. Overall mortality was seen in 6.52%(45/690), maximum in adolescents with ALF presentation [10.3%(18/174)]. On molecular characterization of infection, viremia was seen in 28.9%(200/690) and all the isolates were Genotype IIIA. CONCLUSIONS The number of adults experiencing symptomatic HAV infection was seen to increase over the years in the present study. Infection in adolescents was associated with higher mortality and ALF as the clinical presentation.

Standard-Volume Is As Effective As High-Volume Plasma Exchange for Patients With Acute Liver Failure. J Clin Exp Hepatol 2024; 14:101354. [PMID: 38406612 PMCID: PMC10885581 DOI: 10.1016/j.jceh.2024.101354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Accepted: 01/26/2024] [Indexed: 02/27/2024] Open
Abstract
Background/Aims Acute liver failure (ALF) is associated with fatal outcomes without liver transplantation. Two randomized studies reported standard volume (SV) and high volume (HV) plasma exchange (PLEX) as effective therapeutic modalities for patients with ALF. However, no studies have compared the safety and efficacy of SV with HV PLEX, which we aimed to assess. Methods This retrospective study included patients with ALF admitted between March 2021 and March 2023 who underwent PLEX. All patients underwent HV PLEX until May 2022, and then thereafter, SV PLEX was performed. The objectives of the study were to compare transplant-free survival (TFS) at 30 days, efficacy in reducing severity scores, biochemical variables, and adverse events between SV (total plasma volume x 1) and HV (total plasma volume x 1.5-2) PLEX. Results Forty two ALF patients (median age: 23.5 years; females: 57.1%; MELD Na: 34.67 ± 6.07; SOFA score- 5.24 ± 1.42) underwent PLEX. Of these, 22 patients underwent SV-PLEX, and 20 underwent HV-PLEX. The mean age, sex, etiology distribution, and severity scores were similar between the groups. The median number of PLEX sessions (2) was similar in both groups. On Kaplan-Meier analysis, TFS was 45.5% in SV group and 45% in HV group (P = 0.76). A comparable decline in total bilirubin, PT/INR, ammonia, and MELD Na scores was noted in both groups. The cumulative number of adverse events was similar between the HV group (77.3%) and SV group (54.5%; P = 0.12). Conclusions SV PLEX is safe and as effective as HV PLEX in patients with ALF. Further randomized controlled trials with a larger sample size are needed to validate these findings.

Indian J Gastroenterol 2024; 43:505-512. [PMID: 38664345 DOI: 10.1007/s12664-024-01577-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Accepted: 03/19/2024] [Indexed: 05/28/2024]
Abstract
BACKGROUND AND OBJECTIVES Hepatitis A virus (HAV)-related hepatitis is witnessing an epidemiological transition with increasing trends in adults. While uncomplicated hepatitis remains common, evidence suggests it to be a growing cause for acute liver failure (ALF). In between the two extremes exists severe acute liver injury (s-ALI) which has a propensity to transition to ALF. We aimed at describing the clinical profile of patients with HAV-related s-ALI and identifying potential predictors of progression to ALF. METHODS This was a single-center retrospective analysis of adult patients admitted with HAV-related s-ALI between April 2022 and December 2023. Demographic and laboratory parameters were compared between patients with only s-ALI and those with ALF. Predictors of progression from s-ALI to ALF were identified using logistic regression. RESULTS Forty-three patients satisfied criteria of s-ALI, of which 33 (76.7%) had only s-ALI, while 10 (23.3%) had ALF. Patients with s-ALI had lesser leukocytosis (6.3 ± 3 vs. 13.2 ± 4.8), less incidence of acute kidney injury (9.1% vs. 40%) and lower model for end-stage liver disease (MELD) (20 [18-24.5] vs. 31.5 [26-42]), arterial lactate (2.1 [1.3-3.1] vs. 6.3 [5.2-8.0]), arterial ammonia (94 [72-118] vs. 299 [188-573]), procalcitonin (0.5 [0.28-1.25] vs. 3.2 [1.2-6.1]) and ferritin (482 [213-1633] vs. 5186 [1341-11,053]) compared to HAV-ALF (p < 0.05 for all). Three patients (9.09%) with s-ALI progressed to ALF of whom one (3%) died. Baseline ammonia levels (unadjusted odds ratio [OR] 1.03 [1.01-1.06]) and leukocyte count (OR 1.00 [1.00-1.01]) tended to be associated with ALF progression, although none was significant after multi-variable adjustment. Ammonia levels had an area under receiver operating curve of 0.816 (0.64-0.93) (p = 0.009) (cut-off of 144 μmol/L). Additional comorbidities did not impact overall outcomes. CONCLUSION HAV presents as s-ALI in young adults, with almost one in 10 progressing to ALF. Baseline ammonia may be an important predictor of progression even in s-ALI, but mandates larger well-designed studies.

Abstract
Adolescents and young adults are the driving force of social development, and the prevalence of acute viral hepatitis (AVH) in this population cannot be ignored. At present, there are few studies on the disease burden of AVH in this age group, and most studies focus on chronic liver disease. In this study, we identified global trends in the burden of AVH among adolescents and young adults (15-29) to help policymakers implement precise disease interventions. In this observational study of disease trends, we collected data exclusively from the Global Burden of Disease (GBD) 2019 study. This study examined the trends in the prevalence, incidence and mortality of AVH among adolescents and young adults in 21 regions of the world from 2009 to 2019. Age-specific disease trends were analysed with a joinpoint regression model. The overall global disease burden of AVH declined. The prevalence rate per 100,000 people decreased from 316.13 in 2009 to 198.79 in 2019, the incidence rate decreased from 3245.52 in 2009 to 2091.93 in 2019, and the death rate decreased from 0.87 in 2009 to 0.43 in 2019. During the study period, the prevalence of hepatitis B virtues (HBV) in the young population decreased, but the downward trend of other types of hepatitis other than HBV was not obvious, especially HAV, which even showed an upward trend. Among adolescents and young adults aged 15-29 years, Western Saharan Africa had the highest prevalence of AVH in 2019. There were significant differences in mortality rates among different age groups; 20-24 was the age group with the highest mortality rate from 2009 to 2019, followed by the 15-19 and 25-29 age groups. Although the overall global AVH disease burden declined, some causes of AVH, such as HAV, showed an upward trend during the study period. In addition, the prevalence of AVH among adolescents and young adults in Asia and Africa was higher than that in other parts of the world and warrants more attention. Finally, more research should be conducted on mortality in the 20-24 age group.

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 cross-sectional study aimed to assess seroprevalence of hepatitis A virus (HAV) antibodies and identify factors associated with HAV seropositivity among children and adolescents aged 1-18 years who resided in Chiang Mai, Thailand. Sociodemographic characteristics, sanitation/hygiene, and history of HAV vaccination were collected. Anti-HAV IgG antibody was determined, and a level ≥ 1.0 S/CO defined HAV seropositivity. We enrolled 300 participants; median age 8.7 years, 54% male, and 13% overweight (BMI z-score: + 1 to + 2 standard deviation [SD]). Sixty-five participants (22%) were vaccinated against HAV. Overall, 84/300 participants (28%) demonstrated HAV seropositivity, of whom 55/65 (85%) and 29/235 (12%) were among vaccinated and unvaccinated participants (P < 0.001), respectively. Previous HAV vaccination (adjusted odds ratio [aOR] 47.2; 95% CI 20.0-111.8) and overweight (aOR 4.4; 95% CI 1.7-11.3, compared with normal weight [BMI z-score: - 2 to + 1 SD]) were significantly associated with seropositivity of HAV. In the stratified analyses, crowded bedroom (aOR 3.2; 95% CI 1.3-7.8, per one person increase) and overweight (aOR 5.0; 95% CI 1.8-13.7) were factors associated with HAV seropositivity among vaccinated and unvaccinated participants, respectively. Seroprevalence of HAV antibodies in healthy Thai children and adolescents was relatively low. Recommendation of HAV vaccination for these populations, particularly those with high-risk conditions, should be considered.

Abstract
Street foods play important socioeconomic and cultural roles and are popular worldwide. In addition to providing convenient and low-cost meals for urban populations, street food offers an essential source of income for vendors, especially women, and it can reflect traditional local culture, which is an important attraction for tourists. Despite these benefits, the microbiological safety of street food has become a worldwide concern because it is often prepared and sold under inadequate safety conditions, without legal control and sanitary surveillance. Consequently, high counts of fecal indicator bacteria and several foodborne pathogens have been detected in street foods. This review provides insight into the microbiology of street food, focus on the associated microbiological safety aspects and main pathogens, and the global status of this important economic activity. Furthermore, the need to apply molecular detection rather than traditional culture-based methods is discussed to better understand the actual risks of microbial infection associated with street foods. Recognition is always the first step toward addressing a problem.

Abstract
With the changing hepatitis A epidemiology in India, focal viral outbreaks are being reported from different parts of the country. This study presents Hepatitis A Virus (HAV) strain characterization (period 2009-2020) from 18 states of India. For that, blood and stool samples (n = 280) were screened for HAV RNA and sequences for 5'non-coding and VP3 regions were generated from positive samples (n = 68). Presence of a single IIIA genotype in all samples indicated IIIA being the only HAV genotype currently circulating in India. Interestingly, it was evident that these strains form two distinct groups suggesting independent evolution of these two clusters.

Abstract
Viral infections by hepatotropic viruses can cause both acute and chronic infections in the liver, resulting in morbidity and mortality in humans. Hepatotropic viruses, including hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV), and hepatitis E virus (HEV), are the major pathogens that cause acute and chronic infections in humans. Although all of these viruses can cause acute hepatitis in humans, HAV and HEV are the predominant causative agents in Bangladesh, where the occurrence is sporadic throughout the year. In this review, we provide an overview of the epidemiology of hepatotropic viruses that are responsible for acute hepatitis in Bangladesh. Additionally, we focus on the transmission modes of these viruses and the control and prevention of infections.

Abstract
Vaccination is undoubtedly the most effective and economical way of dealing with the diseases which can affect masses. Pediatric immunization against vaccine preventable disease (VPD) is being supported by most of the international health agencies, making them accessible and affordable to even the poorest of the countries. However, adult vaccination is needed to protect the most productive age group and improve the quality of life of the aging population and is left to those who can afford it. In most of the low- and middle-income countries including India, adult vaccination did not even find a mention in national vaccination policies. Although recommendation exists from various health associations in India for adult vaccination, they have not been given enough publicity as data on burden of VPDs and cost-effectiveness of these vaccines in adults are not available. Most of the general population and a substantial proportion of health care professionals in India lack awareness on the availability and need for these adult vaccinations. Now with improved childhood immunization and increased life expectancies, many diseases are showing epidemiological shift to the later part of life, thereby bringing the focus on adult immunization through the life course approach to reduce morbidity and mortality because of VPDs in adults and improve the quality of life of those left vulnerable because of aging or their existing medical condition.

Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) pandemic has brought fundamental changes to our problems and priorities, especially those related to the healthcare sector. India was one of the countries severely affected by the harsh consequences of the COVID-19 pandemic.
AIM To understand the challenges faced by the healthcare system during a pandemic.
METHODS The literature search for this review was conducted using PubMed, EMBASE, Scopus, Web of Science, and Google Scholar. We also used Reference Citation Analysis (RCA) to search and improve the results. We focused on the published scientific articles concerned with two major vital areas: (1) The Indian healthcare system; and (2) COVID-19 pandemic effects on the Indian healthcare system.
RESULTS The Indian healthcare system was suffering even before the pandemic. The pandemic has further stretched the healthcare services in India. The main obstacle in the healthcare system was to combat the rising number of communicable as well as noncommunicable diseases. Besides the pandemic measures, there was a diversion of focus of the already established healthcare services away from the chronic conditions and vaccinations. The disruption of the vaccination services may have more severe short and long-term consequences than the pandemic’s adverse effects.
CONCLUSION Severely restricted resources limited the interaction of the Indian healthcare system with the COVID-19 pandemic. Re-establishment of primary healthcare services, maternal and child health services, noncommunicable diseases programs, National Tuberculosis Elimination Program, etc. are important to prevent serious long-term consequences of this pandemic.

Abstract
BACKGROUND Hepatitis A virus (HAV) infection is a leading cause of viral hepatitis in children, yet the HAV vaccine is not included in the national immunization program (NIP) in Mexico. This study addresses an identified evidence gap of the burden of hepatitis A disease, complications, and associated costs in Mexico by analyzing surveillance and healthcare data. Data review included disease morbidity (incidence and hospitalization), mortality, and healthcare resource utilization costs. METHODS In this observational, retrospective database study, we conducted a systematic screening, extraction, and analysis of outcome data from the national surveillance system in Mexico from January 2000 to December 2019. RESULTS During the analysis period (2000-2019), the average incidence rate/year of HAV cases was 14.7 (5.4-21.5) per 100,000 inhabitants. Children 1-9 years of age (YoA) had the highest average incidence rate/year with 47.8 (14.7-74.5). The average hospitalization rate/year due to HAV infection was 5.8% (2.9-9.6%). Although the highest burden of HAV continued to be in children (1-9 YoA), an increase in incidence and hospitalizations (with complications) in older age groups (≥ 10-64 YoA) was observed. The annual average fatality rate was estimated to be 0.44% (0.26-0.83%) of which 28.8% of deaths were concentrated in adults ≥ 65 YoA. The total direct costs of medical attention due to HAV and related complications were estimated at $382 million Mexican pesos. CONCLUSION The overall results suggest an uptrend in HAV infections in adolescents/adults compared to children in Mexico. Therefore, as the overall incidence risk of HAV infection decreases, the mean age of infection increases. This consequently increases the risk of severity and complications in older age groups, thus increasing the demand for healthcare resources. Our findings provide evidence for including the inactivated HAV vaccine in the Mexican NIP.

Abstract
Hepatitis is defined as inflammation of the liver and is commonly due to infection with The hepatotropic viruses - hepatitis A, B, C, D and E. Hepatitis carries one of the highest disease burdens globally and has caused significant morbidity and mortality among different patient populations. Clinical presentation varies from asymptomatic or acute flu-like illness to acute liver failure or chronic liver disease, characterized by jaundice, hepatomegaly and ascites among many other signs. Eventually, this can lead to fibrosis (cirrhosis) of the liver parenchyma and carries a risk of development into hepatocellular carcinoma. Hepatitis B and C are most notorious for causing liver cirrhosis; in 2019, an estimated 296 million people worldwide had chronic hepatitis B infection and 58 million are currently estimated to have chronic hepatitis C, with 1.5 million new infections of both hepatitis B and C, occurring annually. With the help of latest serological biomarkers and viral nucleic acid amplification tests, it has become rather simple to efficiently screen, diagnose and monitor patients with hepatitis, and to commence with appropriate antiviral treatment. More importantly, the development of vaccinations against some of these viruses has greatly helped to curb the infection rates. Whilst there has been exceptional progress over the years in the management of viral hepatitis, many hurdles still remain which must be addressed in order to proceed towards a hepatitis-free world. This review will shed light on the origin and discovery of the hepatitis viruses, the global epidemiology and clinical symptoms, diagnostic modalities, currently available treatment options, the importance of prevention, and the journey needed to move forward towards the eradication of its global disease burden.

Abstract
Background Hepatitis A is a vaccine-preventable, feco-oral infection due to poor sanitary conditions. It is predominantly acquired during early childhood and results in lasting acquired protective immunity. However, it results in severe disease which can end up in acute fulminant hepatitis and hepatic failure when acquired during adolescence and adulthood. The prevalence of acute hepatitis A is increasing among children, adolescents, and young adults from higher-income households. They acquire this infection at a later age when they are exposed for the first time to contaminated food and drinks after being brought up in a relatively clean environment. This calls for the introduction of the Hepatitis A vaccine in Ethiopia; possibly as part of the Expanded Program on Immunization (EPI). Methods Socio-demographic and clinical data were collected from patients who were diagnosed to have hepatitis A infection at Adera Medical Center in 2020. Results This study showed that clinical acute hepatitis A is becoming common among children, adolescents, and young adults from relatively high-income families. Among patients with acute hepatitis, 89% were from middle and high-income families. Conclusions There is a need for the incorporation of hepatitis A vaccine in the Ethiopian EPI program.

Abstract
As South Africa transitions from endemic to intermediate endemicity, hepatitis A surveillance needs strengthening to monitor trends in disease incidence and to identify outbreaks. We used passive laboratory-based surveillance data from the National Health Laboratory Services to calculate national hepatitis A incidence and to establish thresholds for outbreaks. Incidence was calculated by age and geographic location. The static threshold used two or three standard deviations (SDs) above the mean hepatitis A incidence in 2017–2019, and a cumulative summation (CuSum2) threshold used three SDs above the mean of the preceding seven months. These thresholds were applied to hepatitis A data for 2020. From 2017 to 2020, the mean incidence of hepatitis A IgM was 4.06/100,000 and ranged from 4.23 to 4.85/100,000 per year. Hepatitis A incidence was highest in the Western Cape province (WCP) (7.00–10.92/100,000 per year). The highest incidence was in the 1–9-year-olds. The incidence of hepatitis A in 2020 exceeded the static threshold in two districts of the WCP: Cape Winelands in January and Overberg district in August. The provincial incidence did not exceed the static and CuSum2 thresholds. District-level analysis using either threshold was sensitive enough to monitor trends and to alert district health authorities, allowing early outbreak responses.

Abstract
The Biological E inactivated hepatitis A (HAPIBEV™) vaccine was developed by importing the Healive® vaccine bulk from China and fill-finish it in India. Healive® vaccine is approved in China for both children and adults. This study assessed the safety and immunogenicity of HAPIBEV™ vaccine as compared to the Havrix 720® vaccine of GlaxoSmithKline (GSK) pharmaceuticals when administered intramuscularly (IM) 6 months apart in 1-15 years old hepatitis A virus (HAV) vaccine naive children in India. This Phase 3, single blind, parallel, randomized, active-controlled, two-arm study was conducted at 8 centers in India in healthy HAV vaccine-naive children. Subjects were stratified into 2 age subsets (1-7 and 8-15 years) and randomly assigned to either BE-HAPIBEV™ or GSK's Havrix® vaccine and administered 2 IM injections 6 months apart. The immunogenicity evaluations included: (1) proportion of subjects who achieved the following at Day 210 from baseline: (a) seroconversion (≥20 mIU/mL) with anti-HAV immunoglobulin G (IgG) antibodies, (b) ≥4-fold increase in anti-HAV IgG antibodies, and (c) ≥2-fold increase in anti-HAV IgG antibodies concentration who were already seroconverted at baseline and (2) geometric mean concentrations (GMC) of anti-HAV IgG antibodies at baseline and Day 210. Safety was evaluated throughout the study. A total of 467 (89.8%) subjects completed the study. The non-inferiority criterion was met by HAPIBEV™ vaccine as seroconversion rates in both vaccine groups were 100%. Overall, other immunogenicity evaluations were either similar in both vaccine groups or higher in the HAPIBEV™ group compared with the Havrix® group. The safety profile was also comparable between HAPIBEV™ and Havrix® groups. The most common adverse event (AE) was injection site pain, and the majority of AEs were mild in severity. The HAPIBEV™ vaccine demonstrated an immunological and safety profile on par with Havrix® in 1-15 years old healthy HAV vaccine-naive Indian children. This study is registered with clinical trial registry of India bearing no: CTRI/2019/04/018384 on 02 Apr 2019.

Abstract
Healthcare providers (HCPs) are at increased risk of acquisition and transmission of infectious disease. Vaccinating HCPs is an essential preventive measure to protect them and their patients against communicable diseases, while positively and directly impacting the functioning of the healthcare system. In India, healthcare represents one of the largest employment sectors with 3.8 million HCPs; however, there is limited awareness of national immunisation guidelines for the Indian HCP population. Data from communicable disease outbreaks across India suggest inadequate vaccination rates amongst HCPs; studies have reported influenza and varicella vaccination rates as low as 4.4% and 16%, respectively. In this review, we discuss data highlighting the impact of insufficient vaccination coverage, barriers to vaccination, and the lack of immunisation guidelines amongst HCPs in India. COVID-19 vaccination programmes for HCPs have been critical in slowing the pandemic in India. This provides an opportunity to raise awareness about the importance of vaccines amongst HCPs in India.

Abstract
In most countries of the Middle East and Northern African (MENA) region, a high hepatitis A virus (HAV) endemicity has been documented. Few others, such as Saudi Arabia and Turkey, are transitioning from high to intermediate endemicity. There is a paucity of recently published HAV disease burden that could be useful to inform or strengthen relevant national hepatitis A vaccination policy and other prevention strategies in the region. This review summarizes information on HAV epidemiology before and after the implementation of a childhood hepatitis A vaccination program in Saudi Arabia and Turkey. In both countries, a clear shift in the age of first HAV exposure has been documented, with more homogeneous trends across regions in Saudi Arabia compared to Turkey. Utilizing the experience of Saudi Arabia and Turkey with hepatitis A vaccination, countries in the region are encouraged to foster discussions on potential vaccination strategies suitable for their own setting.

Abstract
The burden of chronic liver disease (CLD) in India is high, particularly among middle-aged men, with nearly 220,000 deaths due to cirrhosis in 2017. CLD increases the risk of infection, severe disease (e.g. hepatitis A virus or HAV superinfection, acute-on-chronic liver failure, fulminant hepatic failure), and mortality. Hence, various countries recommend HAV vaccination for CLD patients. While historic Indian studies showed high seroprevalences of protective HAV antibodies among Indian adults with CLD, the most recent ones found that nearly 7% of CLD patients were susceptible to HAV infection. Studies in healthy individuals have shown that HAV infection in childhood is decreasing in India, resulting in an increasing population of adults susceptible to HAV infection. As patients with CLD are at increased risk of severe HAV infection, now may be the time to recommend HAV vaccination among people with CLD in India.

Abstract
Hepatitis A virus (HAV) infection is still an important health issue worldwide. Although several effective HAV vaccines are available, it is difficult to perform universal vaccination in certain countries. Therefore, it may be better to develop antivirals against HAV for the prevention of severe hepatitis A. We found that several drugs potentially inhibit HAV internal ribosomal entry site-dependent translation and HAV replication. Artificial intelligence and machine learning could also support screening of anti-HAV drugs, using drug repositioning and drug rescue approaches.

Abstract
In the last two decades, outbreaks due to the foodborne hepatitis A virus (HAV) have been frequently reported in India, with adolescents and adults primarily affected. In India, most food handlers are adolescents and young adults who might be exposed to unsatisfactory environmental conditions and poor water quality. This increases the risk of HAV infection and consequently compounds the risk of HAV transmission from food handlers to susceptible populations. Given the shift in hepatitis A endemicity from high to intermediate levels in India, implementing the vaccination of food handlers has become important as it can also contribute to the elimination of hepatitis A in India. This narrative review makes a case for hepatitis A immunization of food handlers in India considering the growing food industry, evolving food culture, and the substantial burden caused by hepatitis A outbreaks.
What is the context?
Hepatitis A disease is a common form of viral hepatitis and is transmitted through contaminated food and water or through close contact with an infected person. The virus with stands high temperature and can survive on surfaces for long periods of time. In India, the burden of hepatitis A has shifted from children to adolescents and adults who are more culnerable to infection. They present a high risk of complications, often requiring hopitalization. The prevention of the disease has often bee neglected, inadequate safety measures for the preparation of food (via food handlers) is a known risk factor for the transmission of hepatitis A.
What is new?
Our review highlights the relationship between food handling and hepatitis A infection among adolescents and adults in Inida. The lack of knowledge of food safety regulations and hygiene measures among food handlers and the organizations that guide them may contribute to the spread of hepatitis A.
What is the impact?
Sanitation efforts, awareness and educational programs for food are needed to help reduce the transmission of hepatitis A virus and disease, yet these measures alone may not be sufficient. Vaccination among high-risk populations such as food handlers can prevent hepatitis A infection and its complications as well as transmission.

Abstract
BACKGROUND Hepatitis A virus (HAV) is a global health concern as outbreaks continue to occur. Since 1999, several countries have introduced universal vaccination (UV) of children against HAV according to approved two-dose schedules. Other countries have implemented one-dose UV programs since 2005; the long-term impact of this schedule is not yet known. METHODS We conducted a systematic literature search in four electronic databases for data published between January 2000 and July 2019 to assess evidence for one-dose and two-dose UV of children with non-live HAV vaccines and describe their global impact on incidence, mortality, and severity of hepatitis A, vaccine effectiveness, vaccine efficacy, and antibody persistence. RESULTS Of 3739 records screened, 33 peer-reviewed articles and one conference abstract were included. Rapid declines in incidence of hepatitis A and related outcomes were observed in all age groups post-introduction of UV programs, which persisted for at least 14 years for two-dose and six years for one-dose programs according to respective study durations. Vaccine effectiveness was ≥95% over 3-5 years for two-dose programs. Vaccine efficacy was >98% over 0.1-7.5 years for one-dose vaccination. Antibody persistence in vaccinated individuals was documented for up to 15 years (≥90%) and ten years (≥74%) for two-dose and one-dose schedules, respectively. CONCLUSION Experience with two-dose UV of children against HAV is extensive, demonstrating an impact on the incidence of hepatitis A and antibody persistence for at least 15 years in many countries globally. Because evidence is more limited for one-dose UV, we were unable to draw conclusions on immune response persistence beyond ten years or the need for booster doses later in life. Ongoing epidemiological monitoring is essential in countries implementing one-dose UV against HAV. Based on current evidence, two doses of non-live HAV vaccines are needed to ensure long-term protection.

Abstract
At present, humanity is confronting with a novel life-threatening challenge from the COVID-19 pandemic infectious disease caused by the novel coronavirus SARS-CoV-2. To date, the various transmission modes of SARS-CoV-2 have not been completely determined. Food products might be carriers for SARS-CoV-2. The COVID-19 pandemic not only can spread through the respiratory tract like SARS and MERS but also the presence of the SARS-CoV-2 RNA in feces of several patients, shows the possibility of their fecal-oral route spread. Besides, people with gastric problems, including gastric intestinal metaplasia and atrophic gastritis, may be susceptible to this kind of COVID-19 infection. Accordingly, food may act as a potential vehicle of SARS-CoV-2 due to whether carry-through or carry-over contaminations. Considering carry-over, SARS-CoV-2 spread from personnel to food products or food surfaces is feasible. Beyond that, some shreds of evidence showed that pigs and rabbits can be infected by SARS-CoV-2. Thus, viral transmission through meat products may be conceivable, indicating carry-through contamination. As the spread rate of SARS-CoV-2 is high and its stability in different environments, especially food processing surfaces, is also remarkable, it may enter foods in whether industrialized processing or the traditional one. Therefore, established precautious acts is suggested to be applied in food processing units. The present review elucidates the risk of various staple food products, including meat and meat products, dairy products, bread, fruits, vegetables, and ready-to-eat foods as potential carriers for transmission of SARS-CoV-2.

Abstract
INTRODUCTION Hepatitis A virus infection is more severe in adults than children. Although vaccination can protect adults, current childhood programs cover a large population more successfully. Childhood vaccination is, therefore, a solution to protecting adults if it induces lasting immunity. Fifteen-year protection has been demonstrated in children, but longer-term data are only available for adults. We aimed to predict long term persistence of antibody in children beyond 15 years and assess if immunological mechanisms triggered by vaccination support longer-term protection. METHODS Long-term clinical studies using hepatitis A (HAV) or A/B vaccines (HAB) containing 720 or 1440 Enzyme-linked immunosorbent assay Units (EU) of hepatitis A virus antigen were identified. Duration of persistence of antibodies and possible protection was determined by descriptively comparing antibody geometric mean concentration (GMC) kinetics, as well as GMC (95% confidence interval) at 15 years post-vaccination across studies. Immunological mechanism studies describing hepatitis A vaccination were identified. RESULTS One study in children 12-15 years (2-dose HAB 720) and four in adults (2-dose HAV 1440 and 3-dose HAB 720) showed comparable GMC kinetics and per year rates of change up to 15 years. At 15 years, the GMC in children [414.7 mEU/ml (336.9; 510.5)] was in the same range as in adults [range 282.6 (217.6; 367.0) to 550.1 (416.0; 727.4)]. Based on these data, mathematical model predictions from adult studies (showing > 85% protected at 50 years) were deemed likely to also apply to children. Studies identified, both humoral and cell-mediated responses are induced following vaccination. CONCLUSION Based on comparable antibody data in adults and children up to 15 years, similar longer-term antibody persistence is expected in children with 2-dose inactivated hepatitis A 720 containing vaccine at least up to 50 years. Accordingly, improving routine childhood hepatitis A vaccination coverage could protect against more severe disease in adulthood.

Abstract
Purpose Suddenly, many cases of fever with jaundice were reported from Sodala area at Jaipur. This outbreak of acute hepatitis at Jaipur Rajasthan was investigated for aetiology and subsequent phylogenetic analysis. Methods Blood samples were collected from 106 symptomatic patients of acute hepatitis and 39 pregnant females (with or without symptoms of hepatitis) during an outbreak at Jaipur. The samples were tested for hepatitis A virus (HAV) and hepatitis E virus (HEV) by serological and molecular methods (polymerase chain reaction [PCR]). Sequencing of nested PCR product was done for phylogenetic analysis. Hepatitis B surface antigen (HBs antigen), anti-hepatitis C virus (HCV), anti-Leptospira and anti-scrub typhus IgM enzyme-linked immunosorbent assay (ELISA) was done for patients negative for HEV and HAV. Results Among 106 symptomatic patients, HEV IgM was positive in 84/106 (79.2%) patients and HEV RNA in 72/106 (67.9%) patients. Among pregnant women, 6/39 (15.4%) were HEV IgM positive and 5/39 (12.8%) for HEV RNA. One (2.5%) pregnant woman died due to hepatitis. All the isolates belonged to genotype 1A of HEV. All HAV, HEV-negative samples were negative for HBs antigen, HCV antibody, Leptospira and scrub typhus IgM ELISA. Conclusion The outbreak was due to HEV genotype 1A. The municipal water supply was contaminated and sanitary conditions and waste disposal were poor in the area. Boiling of drinking water, fixing the water supply pipes and frequent hand washing helped in controlling the outbreak.
