Over 1,000 inmates in California jails test positive for COVID-19

California, the most populous U.S. state, is combating the coronavirus outbreak in jails, with thousands of inmates infected with COVID-19.

More than 500 people at the state's Fresno County Jail have tested positive for COVID-19, the Fresno County Sheriff's Office reported Monday.

Among the nearly 1,200 people tested, at least 507 returned positive for the virus and 472 were negative. An additional 186 people are still waiting for their test results.

Earlier this month, inmates were quarantined after 13 inmates who had transferred from the Fresno County Jail to the Wasco State Prison tested positive for the coronavirus.

Meanwhile, over 1,000 confirmed cases have been reported in California's San Quentin State Prison. 

Some 1,021 people incarcerated at San Quentin tested positive for COVID-19 as of 3:30 p.m. local time on Monday, according to data from the California Department of Corrections and Rehabilitation. The data indicates nearly 1 in 3 of the prison's total population of 3,507 has been infected. 

A total of 89 staff members at San Quentin have also been infected with the virus.
