Seroprevalence of IgG antibodies against hepatitis-A infection among individuals aged 6-30 years in India, 2021: a nationwide population-based cross-sectional study.

ABSTRACT:

Background

India accounts for one-fifth of the global hepatitis A virus (HAV) infections and half of HAV-related deaths. There is a lack of nationally representative population-based data on the endemicity of HAV to inform vaccination policy. We aimed to estimate the age-specific seroprevalence of HAV infection among individuals aged 6-30 years.

Methods

We used serum samples collected during the fourth national COVID-19 serosurvey conducted between 14 June and 6 July 2021 to estimate the seroprevalence of HAV infection. The survey was conducted in 70 randomly selected districts across 20 Indian states and one union territory. We tested the serum samples from individuals aged six to 30 years for IgG antibodies against HAV. We estimated the overall and state-specific seropreva
