FRESNO, Calif. — The Fresno County Department of Public Health and Sheriff's Office are investigating a possible Mumps virus outbreak at the Fresno County Jail after several inmates reported symptoms to medical staff.

Authorities said they are investing one inmate who may have contracted the virus, and are testing several other inmates who reported symptoms.

Due to the possibility some inmates have contracted the Mumps virus, several pods in the North Jail have been quarantined to ensure there is no additional spread of the virus.

"We are working closely with the Department of Public Health to ensure the health and safety of all the inmates and employees within the jail," the Fresno County Sheriff's Office said in a release.

Inmates in the specific housing areas are being assessed daily and immunizations are being offered to both inmates and jail staff as soon as they become available.

The Sheriff’s Office is aware that the Mumps virus has been diagnosed in several California prisons and jails and recently underwent specific training to identify any potential inmates who may have contracted the virus.

The Fresno County Superior Court has been made aware of the situation and will only call inmates to court if necessary.
