Cache Countyâs latest COVID-19 infection numbers include a spike in cases, much of which local epidemiologists are attributing to an outbreak at the Cache County Jail. On Friday, the Bear River Health Department reported 42 new coronavirus infections in Cache County, along with 74 on Thursday. Prior to Thursday, the countyâs rolling 7-day average had been hovering around 20 new cases daily. After the spike, that rolling average is up to about 27 new cases daily. âAside from the jail outbreak, itâs pretty normal growth from what we expected from where we were in the past two weeks,â said BRHD Epidemiologist Caleb Harrison. âA pretty slow and steady increase.â
