Hennepin County Adult Detention Center's Response to a 2019 Hepatitis A Outbreak in Minnesota.

Hennepin County Adult Detention Center (Jail) is Minnesota's largest jail. In August 2019, the Minnesota Department of Health declared a statewide hepatitis A outbreak. Within three days, Hennepin County Jail Health Services made significant changes to vaccination protocols that increased vaccination rates from 0.6% to 7.1% among detainees, who have a greater risk of contracting hepatitis A. We highlight the opportunity for jails to develop sustainable public health interventions in the setting of community outbreaks.
