Likelihood of COVID-19 Outbreaks in US Immigration and Customs Enforcement (ICE) Detention Centers, 2020‒2021

To determine facility-level factors associated with COVID-19 outbreaks in US Immigration and Customs Enforcement (ICE) detention centers. We obtained COVID-19 case counts at 88 ICE detention facilities from May 6, 2020, through June 21, 2021, from the COVID Prison Project. We obtained information about facility population size, facility type (dedicated to immigrants or mixed with other incarcerated populations), and facility operator (public vs private contractor) from third-party sources. We defined the threshold for a COVID-19 outbreak as a cumulative 3-week incidence of 10% or more of the detained population. Sixty-three facilities (72%) had at least 1 outbreak. Facilities with any outbreak were significantly more likely to be privately operated ( .001), to have larger populations (113 vs 37; .002), and to have greater changes in their population size over the study period (‒56% vs -26%;
