Which population is considered high risk for Hepatitis A prophylaxis in public health guidelines?

• A. Elderly
• B. Homosexual men
• C. Pregnant women
• D. Healthcare workers

Answer: (B)

Hepatitis A is mainly spread through the fecal-oral route, so vaccination and prophylaxis focus on groups with higher exposure to the virus. Men who have sex with men are considered high risk because sexual practices in this group have been linked to HAV transmission and outbreaks; public health guidelines target vaccination to help prevent these clusters. The other groups don’t have the same exposure pattern. While older adults may have more severe disease if infected, they aren’t automatically a high-exposure group for HAV prophylaxis. Pregnancy doesn’t by itself create higher exposure risk, though vaccination can be considered if indicated by risk. Healthcare workers aren’t singled out as a high-risk population for HAV prophylaxis unless they have direct exposure or are in a setting with increased risk.
