Molecular characterisation of hepatitis A in the Western Cape province, South Africa in 2023.

In 2023, passive laboratory-based surveillance showed an increase in hepatitis A virus (HAV) infection. We investigated hepatitis A incidence using the notifiable medical condition surveillance system (NMCSS) data and molecularly characterised positive blood samples from the Western Cape province for 2023. All HAV IgM seropositive cases from the NMCSS from 1 January to 31 October 2023 in South Africa were investigated.

Exploring the Epidemiological Surveillance of Hepatitis A in South Africa: A 2023 Perspective.

Hepatitis A (HAV) presents a significant global health concern with diverse clinical manifestations primarily transmitted through fecal-oral routes, emphasizing the critical role of sanitation and water cleanliness in transmission dynamics. Age-related variations, notably asymptomatic presentation in children, add complexity. The World Health Organization's (WHO) endemicity classification aids in understanding prevalence and control strategies.
