Kings County on Sunday reported 130 additional people have tested positive for COVID-19, including 115 inmates at Avenal State Prison.
Positive cases of coronavirus at the prison have increased significantly since May 18, when the first cases were reported there.
As of Sunday evening, Kings County has reported a total of 647 cases since the outbreak started. Of those, 197 cases were reported from Avenal State Prison.
The Kings County Department of Public Health says the jump in positive cases in the prison is due to extensive testing being carried out through a multi-agency partnership.
A spokesperson for the California Department of Corrections and Rehabilitation says the prison is currently testing as many inmates and staff as possible and following isolation and quarantine guidance to help slow the spread of the virus.
