thursday in the individual competition where she is champion. but we'll begin with a major reversal. the centers of disease control is recommending everyone go back to wearing masks indoors even if you're vaccinated. it also said that people who are fully vaccinated can still pass the delta variant to others. here in the bay area, some business owners are already reposting masks required signs. the cdc says with cases surging nationwide, even vaccinated people should mask up. it's a recommendation every bay area county made more than a week ago. but solano's commissioner has not followed and calls the message misguided. >> what is causing the surge is all in people's homes, back yards, camping, it is not in the environment where these mask recommendations are going to apply. >> the health commissioner has

he will not be returning to a mask mandate. that means he will be the only county in the bay area requesting that people wear a mask indoors. the delta variant of covid is increasing. there is a new one now, delta plus, a new variant. we sat down with someone to learn about the new variant of the variant. >> reporter: they've gone to every hospital in the county, and so far they've detected 16 variants of the delta variant, named delta plus. >> it's a variant of a variant. >> reporter: the variant is called delta plus and has an additional mutation believed to also be highly contagious. according to the county's dashboard it sequenced 15 cases

of two new delta variants which scientists are now examining. >> i think it's a safe bet to assume that it is also more contagious, just like the delta variant is. >> reporter: it's not known yet if the current vaccines offer protection against the delta plus variants. however, deputy public health officer dr. george hahn says right now most people hospitalized with covid in the county is unvaccinated. and there is another change in cases compared to january. >> if the delta variant has increased rapidly in santa clara county and in the bay area, as you know, delta is now the predominant variant in california and in the country, and the same is true in santa clara county. >> reporter: so far there have been 152 delta variant cases in santa clara county. and while he says there have been breakthrough cases where fully vaccinated people are still diagnosed with covid, he stresses that getting vaccinated will offer the best protection

against extreme illness. even if you get the delta or delta plus variants. in san jose, marianne favro, nbc bay area news. the cdc also says kids should be masked up when they head back into the classroom this fall. the cdc made this new recommendation for all students k through 12. this includes kids who have already been vaccinated, as well as teachers and staff. this comes a week after the american academy of pediatrics recommended that children two or older should wear a mask in school. today the largest public university system in america joined a growing number of universities that will require the vaccine if you want to be on campus. the california state university system says it will require anyone using csu facilities to be fully vaccinated by the end of september. nbc's bay area damien tra --

trujillo says people's agreements are mixed. >> for some in california state, vaccines for everybody is the next step. >> to have everyone vaccinated is less of a chance to get covid, especially with the variant going around. i think it's a smart decision. >> reporter: csu says they will require vaccines for all the faculty, staff and students who visit any of the campuses. each student has until september 30 to work through the steps. the opinions here vary and there is no shortage of them. some students don't like that the choice is being taken from them. >> my education is on the line and it just feels like i'm

getting bribed for it. for me to get my education i need to do this other thing on top of paying my tuition and everything else. >> i think it's also a little unfair for those who have their religious beliefs and feel like everyone can come back to campus just so they don't feel excluded. >> reporter: csu says its policy will allow for verified religious and medical exemptions, and the university system says it's in the meet and confer process with labor unions, and employees will face no discipline while that process is underway. this as a nation faces a fourth surge largely driven by the unvaccinated. at the california campus, nbc bay area news. let's get back to our coverage of the olympics. a large look at the olympic flame. the world still buzzing about biles. it was a stunning turn in the women's gymnastics team competition in tokyo.

the ground. that's just not right. so there's a lot of work to be done, but i've spoken to the mayor, i've spoken to congresswoman lee. i feel very optimistic that change is coming. >> boxer says she supports more community policing in oakland. the 80-year-old served in the senate for 24 years and says despite this experience, she is not moving out of town. all right, it is gaining steam. that's the word from a new poll at uc berkeley suggesting that the effort to recall governor newsom is gaining momentum. the election now just seven weeks away. nbc's tom jensen is in san francisco today where the republican frontrunner looked to bolster his case. >> reporter: former san diego mayor kevin faulkner stumping in san francisco today to highlight what he calls the governor's failed policy on crime. >> californians are angry, ia k
