Figure 1

Incidence rates for hepatitis A virus (HAV) in source plasma donors, United States, 2016‒2020. Shown are monthly HAV incidence rates based on routine viral marker testing. Incidence rates correspond to monthly number of previously HAV RNA-negative donors with a first positive HAV nucleic acid testing result per 100,000 donors.
