Objective: To study the frequency of Hepatitis A Virus and Hepatitis E Virus infections in adult patients of acute hepatitis in a Tertiary Care Hospital in Lahore. Methods: All samples received from medical units (indoor and outdoor) of Mayo hospital Lahore from 26 Feb.2019 to 26.Sept.2019, for Hepatitis A & E IgM antibody testing by ELISA were included in the study. The results and other relevant information were recorded on proforma. Results: Out of 690 study subjects, 62% were male and 38% were female. The mean age ± SD was 33.8 + 7.4years. The percentage of HAV or HEV infected cases was 59%,and 41% were not infected with HAV or HEV. The frequency and percentage of Hepatitis AVirus was 62(15%),whereas the frequency and percentage of HEV was 327(80%) and that of co-infection with HAV and HEV was 21(5%). The mean + SD age of Hepatitis AVirus was 35.2 + 5.0,whereas the mean + SD age of Hepatitis E Virus and co-infection with Hepatitis A and Hepatitis E Virus were 31.45 + 2.3 and 22.6 + 6.3 years, respectively. Conclusion: Hepatitis E Virus is the commonest cause of acute hepatitis in our study,followed by hepatitis A Virus and coinfection of HAV and HEV. Key words: Frequency, Hepatitis A infection, Hepatitis E infection, Co- infection Hepatitis A & Hepatitis E.

Background: Hepatitis A virus (HAV) and hepatitis E virus (HEV) cause acute hepatitis in humans and are transmitted mainly through the fecal-oral route. They pose major health problems in developing countries. This study was done to determine prevalence of HAV and HEV in patients presenting with AVH and the co-infection of HAV and HEV in these patients.Methods: The study was conducted in the virology research and diagnostic laboratory, PGIMS Rohtak during the study period of August 2017-December 2018. The study population included sera of individuals from all age group who were suspected of acute viral hepatitis (AVH). All the sera were screened for IgM antibody to HEV and HAV using IgM capture ELISA.Results: HEV IgM ELISA test   was performed in 307 patients (mean age 34 years;), with an overall seroprevalence rate of 138(44.9%). HAV antibodies were detected in 109 subjects, with a median age of 9.5 years the seroprevalence of HAV was 34 (31.1%). HEV seropositivity was highest in the age group 20-30 years. Mean age was 34 years whereas the interquartile range was from 14-71 years. HAV infection was positive mainly in the age group <10 years. With interquartile range from 6-16 years. Out of total 34 patients positive for HAV infection males were 20 (58.8%), whereas females were 14(41.1%). HEV IgM was positive in 138 patients, out of which male were 96 (69.56%) and females were 42 (30.43%). HEV IgM was positive in 138 patients, out of which male were 96 (69.56%) and females were 42 (30.43%). HAV and HEV seen to be prevalent all with highest predominance seen towards the end of monsoons (August and September) and beginning of winters.Conclusions: The present study also points toward HEV being the prime etiological agent for outbreaks of acute hepatitis in the studied region of Haryana (Rohtak), India. A comparatively lower HAV prevalence may be the consequence of an overall declining trend due to improved living standards and environmental hygiene.

ABSTRACT Foodborne viruses including hepatitis A virus (HAV), norovirus (NoV), rotavirus (RoV) and hepatitis E virus (HEV) are easily transmitted through contaminated seafoods. The current research was done to assess the incidence of RoV, NoV GI and GII,hAV and hEV in fish and shrimp samples caught from the Persian Gulf, Iran. Three-hundred and twenty fish and shrimp samples were collected. The presence of foodborne viruses were assessed by the real-time PCR. Forty-nine out of 320 (15.31%) fish and shrimp samples were positive for foodborne viruses. Distribution of hAV, NoV GI and NoV GII amongst all studied samples were 0.93%, 5.93% and 8.43%, respectively. hEV and RoV viruses were not found in studied samples. Parastromateus niger and Scomberomorus commerson fish and Penaeus monodon shrimp were the most frequently contaminated samples. Simultaneous incidence of hAV and NoV GI and hAV and NoV GII were 0.31% and 0.93%, respectively. Distribution of foodborne viruses in samples collected through spring, summer, autumn and winter seasons were 14.28%, 9.33%, 11.76% and 24.44%, respectively. Findings revealed that the incidence of foodborne viruses was significantly associated with seafood species and also season of sampling.
