"We extend our heartfelt sympathies to the patient's family and friends," said county health officer Dr. Nichole Quick. "This serves as a very unfortunate reminder to the community about the importance of staying at home and social distancing when leaving the household for essential activities, or to work at an essential business, in order to slow the spread of COVID-19 and help protect our most vulnerable neighbors."
Among the new cases was an inmate at Orange County Jail who tested positive for COVID-19, according to a news release from the Orange County Sheriff's Department.
Officials said the inmate, a man in his 40s, was booked into the Orange County Jail on June 17, 2018 on suspicion of child endangerment, torture, false imprisonment and assault with a deadly weapon.
The inmate was recently isolated for flu-like symptoms and tested for COVID-19. The positive test results were returned on Tuesday.
Officials said the inmate remains in isolation, is receiving medical treatment with moderate symptoms, and currently does not need to hospitalized.
The jail has an electronic card system in the facility that will allow the department to identify all inmates and staff who had contact with the inmate in order to notify them of the potential exposure, according to the news release.
Inmates who were potentially exposed will be closely monitored for symptoms. Their movement inside the jail will be restricted for up to 14 days.
