The Los Angeles County Department of Health updated its COVID-19 safety measures Wednesday and mandated that all of the county's businesses must provide N95 or KN95 masks to employees who work indoors.
"Well-fitting medical grade masks, and surgical masks," are also acceptable under the order.
"Everyone needs to be sensible about how to protect themselves and those they love by layering on protections whenever around non-household members," LA County's health director, Dr. Barbara Ferrer, said in a statement. "At work, this means upgrading your mask if you work indoors and you are in contact with other workers or members of the public."

2022 Grammy Awards postponed due to omicron variant
The 2022 Grammy Awards have been postponed due to the surge in COVID-19 cases linked to the omicron variant.
"After careful consideration and analysis with city and state officials, health and safety experts, the artist community and our many partners, thx have postponed the 64th Annual GRAMMY Awards Show," CBS and the Recording Academy said in a joint statement.
The statement continued, "The health and safety of those in our music community, the live audience, and the hundreds of people who work tirelessly to produce our show remains our top priority. Given the uncertainty surrounding the Omicron variant, holding the show on January 31 simply contains too many risks."
A future date for the Grammys has yet to be announced.
The awards show was scheduled to be held at the Arena in Los Angeles and hosted by "The Daily Show's" Trevor Noah.
This is the second year in a row that the Grammys has been postponed. Last year, the show was held in March after its original date was canceled in January.
COVID vaccinations in US drop 42% over last three weeks
The number of COVID-19 vaccinations in the U.S. has declined over the last three weeks despite the surging number of cases due to the omicron variant.
In the past, surges have driven Americans to get vaccinated. However, data from the Centers for Disease Control and Prevention shows the average number of total doses administered has fallen 42% since Dec. 14.
An average of 304,000 Americans are currently receiving their first dose every day and 165,000 are reaching "full vaccination" status.
This is a drop from three weeks prior, when 455,000 were getting their first dose every day and 402,000 were reaching "full vaccination" status.
Additionally, the average number of people receiving booster shots every day has declined to 623,000 from more than one million.
A total of 67.4 million eligible Americans -- aged five and older -- remain completely unvaccinated.

CDC director responds to criticism of COVID-19 guidance
Dr. Rochelle Walensky, director of the U.S. Centers for Disease Control and Prevention, is standing by her agency's new quarantine and isolation guidance for COVID-19, which the nation’s largest association of physicians has criticized as "confusing."
The CDC updated its guidelines on Dec. 27, saying asymptomatic people who test positive for COVID-19 should self-isolate for five days rather than 10. In a scathing statement released Wednesday night, the American Medical Association (AMA) said the new recommendations "are risking further spread of the virus."
"The American people should be able to count on the Centers for Disease Control and Prevention (CDC) for timely, accurate, clear guidance to protect themselves, their loved ones, and their communities. Instead, the new recommendations on quarantine and isolation are not only confusing, but are risking further spread of the virus," the AMA's president, Dr. Gerald E. Harmon, said in the statement. "With hundreds of thousands of new cases daily and more than a million positive reported cases on January 3, tens of thousands -- potentially hundreds of thousands of people -- could return to work and school infectious if they follow the CDC’s new guidance on ending isolation after five days without a negative test."
But Walensky defended the new guidance, telling ABC News' Cecelia Vega in an interview Friday on "Good Morning America" that the CDC "make[s] these recommendations in the context of science, in the context of ongoing epidemiology and in the context of what is feasible in collaboration with our public health and local and state public health partners."
"I've read the AMA statement and I have deep respect for the AMA," Walenskey said, "but I will also say we've heard a lot of support for ongoing guidance from public health partners, from other clinical and laboratory partners as well."
Walensky referenced "dozens of studies" that have shown a COVID-19 patient is most infectious in the one to two days before symptoms and the two to three days after symptoms.
"So by five days after your symptoms, the vast majority of your contagiousness is really behind you," she said. "And what we say at day five then is, are your symptoms gone? Are you feeling better? Is your cough gone, sore throat gone? And if so, then it is safe to go out if you are wearing a mask all the time. And that means not going out to restaurants, not going out to gyms, not going out and visiting grandma, but really conscientiously wearing your mask for those last five days."
Walensky noted that people may choose to take an antigen or at-home test at day five, if they have access to one. But it's not required.
"If that test is positive, you should stay home for those extra five days. But if that test is negative you should go out and continue to wear your mask," she said. "You know, these tests are actually not authorized for the purpose of evaluating contagiousness."
