California brought back the mask mandate it lifted in June 2021 in December as part of a winter surge in COVID cases. Now it will lift that mask mandate from December next week on February 16. However, several large cities/counties will still keep their own mask mandate, such as with Los Angeles and San Francisco (that only makes sense).
For us as a state to effectively stop the spread, I really think we ought to utilize proof of vaccination more; it’s not hard since it’s so easy to obtain. Locally, my college (FCC) requires proof of vaccination/negative test to enter certain buildings, like the library, and the only business I’ve seen thus far requiring vaccination is Splash (night club).
