Molecular Genotyping of Hepatitis A Virus, California, USA, 2017-2018

Emerg Infect Dis. 2019 Aug;25(8):1594-1596. doi: 10.3201/eid2508.181489.

Abstract

We implemented subgenomic and whole-genome sequencing to support the investigation of a large hepatitis A virus outbreak among persons experiencing homelessness, users of illicit drugs, or both in California, USA, during 2017-2018. Genotyping data helped confirm case-patients, track chains of transmission, and monitor the effectiveness of public health control measures.

Keywords: California; United States; genotyping; hepatitis A virus; outbreak; public health; viruses.
