The study highlights a significant epidemiological shift in hepatitis A seroprevalence in South Korea, with teenagers and young adults becoming the most susceptible groups, emphasizing the need for targeted vaccination strategies.
Lee et al. (2011) conducted a cross-sectional in Hepatitis A virus (HAV) infection (n=25,140). Year of testing and age group was evaluated on Area-adjusted anti-HAV seroprevalence rate (p=<0.001). The most susceptible age group to HAV infection in South Korea was 10-29 years (11.9% seroprevalence for 20-29 years in 2009), while seropositivity in children under 10 increased from 33.4% to 69.9%.
