Geographic distribution of hepatitis A virus–positive plasma donors, United States, 2016‒2020. Cumulative case counts are indicated: A) 2016; B) 2016–2017; C) 2016–2018; D) 2016–2019; E) 2016–2020. These counts reflect how hepatitis A outbreaks in the United States have spread and spilled over into the plasma donor population over time. No color indicates states for which no data are available (no plasma collection). Maps were created by using an Adobe Stock template (https://stock.adobe.com).
