A California county has issued an order that face masks must now be worn inside certain healthcare facilities due to the "risk of COVID, flu and other respiratory virus-related illnesses" over fall and winter months.
Sonoma County interim health officer Dr. Karen Smith issued the order on Monday, and the mandate will come into effect on November 1.
A Sonoma County Health Department spokesperson told Newsweek, "The timing of this order was done in conjunction with other Bay Area counties and in anticipation of a winter surge in COVID and flu, which is typical nationally, if not globally."
Why It Matters
The order is designed to protect the county's "most vulnerable populations" including the elderly and cancer patients in health care facilities during the fall and winter months, a spokesperson for the Sonoma County Department of Health told Fox News. It is also designed to prevent medical staff from getting ill.
Influenza is believed to be emerging this year as even more deadly than COVID in the United States. Last winter, flu made between 47 to 82 million people sick in the U.S., with 27,000 to 130,000 people dying from the illness, according to estimates from the Center for Disease Control and Prevention (CDC).
What To Know
The order applies to the following health care facilities in Sonoma County: skilled nursing facilities, sections of long-term care facilities where nursing care is provided, acute and non-acute rehabilitation facilities, infusion centers and dialysis centers.
Masks will be required in areas including registration desks, waiting rooms, examination rooms, therapy rooms and other areas where patients and health care providers interact.
When asked whether it was possible the order could be extended to additional facilities, the Sonoma County Health Department spokesperson said it was "unlikely."
"That said, hospitals and other facilities can always issue their own masking orders, particularly if the situation becomes dire," the spokesperson added.
There will be some exemptions, including anyone "with a diagnosed medical condition, mental health condition, or disability that prevents the individual from wearing a face mask." People who are hearing impaired and need to see another person's mouth for communication will also be exempt.
The order says that appropriate face masks are surgical masks, or KN95, KF94, or N95 respiratory masks. However, informal masks such as a scarf, ski mask, balaclava, bandana, turtleneck, collar, cloth mask, or any face covering that has an "unfiltered, one-way exhaust valve" does not qualify.
Those who are not exempt and fail to comply with the order may face fines, imprisonment or both.
The Sonoma County health officer has been issuing similar orders since 2017. This year's order affects fewer health care facilities than in previous years, but the county has emphasized that all facilities are "strongly recommended to encourage the use of face masks throughout the respiratory virus season, regardless of vaccination status."
Additionally, Smith also "strongly" advised everyone over the age of six months to get the current COVID, flu and respiratory syncytial virus (RSV) vaccines if they are eligible.
What People Are Saying
A Sonoma County Health Department spokesperson told Newsweek: "Sonoma County is just coming off of the summer surge and anticipates the winter surge will begin around the winter holidays. Dr. Smith issued the masking order because patients and residents in the specified health care facilities are at greater risk for respiratory virus-related hospitalizations and death. Workers in health care facilities are also at risk for respiratory illness and can transmit the viruses to their clients, patients and coworkers. Moreover, respiratory virus-related illness in health care workers can cause absenteeism, placing strain on limited health care resources."
Dr. Karen Smith said in a statement: "The risk to vulnerable patients of COVID, flu and other respiratory viruses in health care facilities remains significant, so it continues to be important for face masks to be used in patient care areas when seasonal risk of exposure to one or more viruses is high."
She added: "In California, vaccines remain covered by insurance for residents of all ages — and they remain the best protection we have against respiratory virus infections."
What Happens Next
The order mandates that masks must be worn in the specified health care facilities from November 1, 2025, until March 31, 2026.
