Laboratory Testing for Hepatitis A and E
Incidence of Acute Hepatitis A by Year

September 2008
Let’s review the current epidemiology of acute Hepatitis A in the United States. In the last 20 years, you can see that the incidence of acute Hepatitis A has decreased remarkably from about 12-14 cases per 100,000 people in population to 2 or fewer cases per 100,000 people in population in the last 10 years. This observation is due in part to improved sanitation and water treatment as well as immunization recommendation from the advisory committee on immunization practice at the CDC. The Hepatitis A vaccine is now a routine vaccination for children.
