COVID-19 Dynamics in an Ohio Prison



Keywords (Tags): ,

A retrospective study of the April 2020 outbreak at the Marion Correctional Institution in Ohio showed rapid, widespread infection, with nearly 80% of inmates infected within three weeks of the first reported case. The authors suggest three scenarios that could have given rise to the outbreak: 1) a single initially infected inmate with a basic reproduction number, R0, greater than 14; 2) a super-spreading event with an R0 = 3; or 3) undetected virus circulation among inmates prior to April.
