Furthermore, the risk of infection varies by geographic region and demographic factors, with certain populations, such as those born in countries with high incidence rates, being at higher risk. Vaccination is recommended for all infants at birth and for individuals at increased risk of the disease, including healthcare workers and those with multiple sexual partners.

Hepatitis A is a contagious virus that spreads through person-to-person contact or by eating contaminated food or drink.

Anyone can get hepatitis A, but certain groups are at a higher risk, including:

  • International travelers
  • Sexual contact with an infected person
  • People who use or inject drugs
  • Those with chronic liver disease, HIV, or who anticipate close contact with an international adoptee are also at increased risk for severe disease from hepatitis A.
