Study finds nearly 16% of Illinois COVID-19 cases linked to spread from Chicago jail

Using data from Cook County Jail, researchers analyzed the relationship between jailing practices and COVID-19 community infections. They found that cycling through Cook County Jail—which accounts for the period of time from arrest to awaiting hearings and trials—is associated with 15.9% of all documented COVID-19 cases in Chicago and 15.7% of those in Illinois.

Many animal species that lived in these habitats also disappeared.
