In the middle of a hepatitis outbreak, US shutters the one Atlanta-based CDC lab that could help

After people started testing positive for hepatitis C in a coastal Florida town in December, state officials collected blood from patients, wrapped their specimens in dry ice and mailed them straight to the Centers for Disease Control in Atlanta, Georgia.

The hepatitis C virus, which is spread through contact with infected blood and can lead to deadly liver cancer, is notoriously hard to identify. But if anyone could understand what was happening in Florida, it would be the Division of Viral Hepatitis in the CDC’s headquarters.

Using samples from the laboratory’s collection of nearly 1 million frozen specimens, scientists helped make the initial discovery of the hepatitis C virus in the 1980s. In 2020, that research was awarded the Nobel Prize in Medicine.
