Healthcare-associated Exposure to the Hepatitis A Virus (HAV)

The HAV is transmitted primarily by the fecal-oral route, either person-to-person, i.e., close personal contact with an infected household member or sex partner; or consumption of contaminated food or water.22 HCP with close personal contact with HAV-infected patients should be tested for anti-HA. Anti-HA-positive HCP who have not been vaccinated previously should be administered PEP, i.e., a single dose of hepatitis A vaccine (Vaqta or Havrix) or immune globulin (IG) within 2 weeks after exposure.22
