“Rancho Cordova had a lot of cases in one of the communities starting about three or four weeks ago and Oak Park has a lot of staff members from UC Davis and a lot of UC folks were tested,” said Dr. Peter Beilenson, Director of the Sacramento County Department of Health Services.

Dr. Beilenson says the county is now expanding testing.

“Most importantly we will be testing asymptomatic patients,” he explained.

Dr. Beilenson said more testing will give county officials a better picture of how widespread COVID-19 really is.

“We will be doing some walk-up clinics in neighborhoods in vulnerable communities,” Dr. Beilenson said.

Community member Damitra Barnes said she isn’t taking chances and is continuing to take social distancing seriously.
