Although the overall incidence rate of HAV
infections has decreased within all age groups, a large population of susceptible, unvaccinated adults who were not infected by being exposed to the virus during childhood remain vulnerable to infection by contaminated foods (typically imported from countries with endemic HAV
transmission) and recently, on a much larger scale, through behaviors that increase risk for infection in certain vulnerable populations, such as drug use (3).

(1) In these regions, there are high levels of circulating hepatitis A virus (HAV
), infecting the majority of the population during the first decade of life.
Hepatitis A virus (HAV
), which is from the Picornaviridae family, is an envelope-free and single-stranded RNA virus with linear positive polarity.
Hepatitis A virus (HAV
) infection is the most common cause of acute viral hepatitis, with approximately 1.5 million cases reported globally each year.1 The primary modes of HAV
transmission are contact with an infected person and ingestion of contaminated water or food.2 Although HAV
infection mainly causes self-limited symptoms, acute liver failure following HAV
infection is occasionally observed.

) disease has changed.
