(SACRAMENTO, Calif.) — California issued a new rule on Monday banning unmasked students from school campuses but then rescinded it just hours later.

The California Department of Health published its COVID-19 public health guidance for K-12 schools in the Golden State for the 2021-2022 school year, including a new mandate that said students “are required” to wear face masks indoors, unless they are exempt due to a medical condition, and “schools must exclude students from campus” if they refuse to do so. The guidance, which was initially published on Monday afternoon and took immediate effect, noted that schools “should offer alternative educational opportunities for students who are excluded from campus because they will not wear a face covering.”

But later, officials backtracked on that rule. The California Department of Health took to Twitter on Monday evening to signal a change of direction, saying, “California’s school guidance will be clarified regarding masking enforcement, recognizing local schools’ experience in keeping students and educators safe while ensuring schools fully reopen for in-person instruction.”

The guidance was ultimately revised, dropping the language about excluding unmasked students from classrooms statewide and instead allowing schools to decide how to deal with the issue.

“Consistent with guidance from the 2020-21 school year, schools must develop and implement local protocols to enforce the mask requirements,” the guidance now states. “Additionally, schools should offer alternative educational opportunities for students who are excluded from campus because they will not wear a face covering.”

The California Department of Health says the guidelines are “effective immediately and will be reviewed regularly.” The department further noted that it is operating within the updated recommendations released Friday by the U.S. Centers for Disease Control and Prevention, which continues to advise schools to promote COVID-19 vaccination and implement indoor mask requirements and physical distancing for those who are not fully vaccinated. But the CDC’s guidelines also state that schools “should not exclude students from in-person learning to keep a minimum distance requirement.”

“Students benefit from in-person learning, and safely returning to in-person instruction in the fall 2021 is a priority,” the CDC says.

Nevertheless, California’s COVID-19 measures are among the strictest of any U.S. state. Education and health officials alike are concerned about the so-called delta variant, a highly contagious version of the novel coronavirus, with infections on the rise as the new academic year draws closer.

As of July 7, there were 1,085 confirmed cases of the delta variant in California — a 71% rise from the previous week. Meanwhile, among the COVID-19 tests statewide that are genomically sequenced, the delta variant accounted for 43% on June 21 compared with just 5.8% on May 21, according to data from the California Department of Health.

Overall, California has reported more than 3.7 million confirmed cases of COVID-19 and over 63,000 deaths from the disease. More than 42.4 million doses of COVID-19 vaccines have been administered across to the state, which is home to some 39.5 million people, according to data from the California Department of Health.

(NEW YORK) — While all adults in the United States are now eligible for the COVID-19 vaccine, parents with young children find themselves in an uncomfortable limbo state. Fully vaccinated parents are protected against the virus, but their kids under 12 aren’t even eligible for a shot.

While children are less likely to have serious infection than in adults, with the Centers for Disease Control and Prevention noting that “most children with COVID-19 have mild symptoms or have no symptoms at all,” in rare instances, children have developed severe COVID-19 cases that led to hospitalization or death.

As of early June, 4,000 children nationwide had developed multisystem inflammatory syndrome in children (MIS-C), a rare but serious condition associated with COVID-19. There’s also an element of uncertainty associated with any COVID-19 infection, since the long-term health consequences of having COVID-19 are not yet known.

Navigating kids and COVID is complicated. Come fall, vaccines are likely to be approved for children younger than 12, but until then, some parents are wondering how to keep their kids safe as guidelines about masks and social distancing loosen.

ABC News spoke with Dr. Judith Flores, a pediatrician and former chief of ambulatory care at NYC Health + Hospitals, who has been in practice for more than 30 years, about how parents can lower their kids’ COVID risk.

Q: My kid is going back to school in person this year. What do I need to know?

You should start planning and ask questions, Flores says.

“I would also inquire who is vaccinated at school and keep an eye on what their environmental controls are,” Flores said.

According to the CDC’s guidelines for K-12 schools, “consistent and correct use of face masks reduces the spread of SARS-CoV-2 and, with some exceptions, is recommended for use indoors among people aged 2 and older who are not fully vaccinated.” The CDC also recommends handwashing, improving ventilation, staying home if sick, social distancing and testing in schools to mitigate the risk of COVID-19 outbreaks.

Depending on school guidance and your risk tolerance as a parent, send your child to school with a mask. Flores noted that if she had a small child, she would have them wear a mask at school, especially in the beginning, while you determine whether or not the school is doing a good job of keeping the environment safe.

But ultimately, it’s important to keep in mind that schools have been reasonably safe settings so far.

“It’s been well documented that kids get sicker when they’re home with family,” Flores said.

Despite that reality, some parents are rightfully nervous. Flores works with families that were hit hard by COVID-19’s initial wave in New York City. Some parents and children are anxious about returning in person, she explained, adding that behavioral and mental health support are critical, especially for kids who lost family members during the pandemic.

“It’s not just, ‘let’s make sure we have your supply list for the teacher this year,'” she said. “You really have to prepare your children mentally — and yourself,” she said.

Q: Is there anything I can do to lower my child’s COVID risk until they’re eligible for a vaccine?

“The best way to take care of your child is for you, your family and your community to be vaccinated,” Flores stressed. “Your kid’s risk goes up depending on the community you live in or go to school in. If your community has a low vaccination rate and high infection rate, there’s a greater risk your child will get sick.”

“If I were in Mississippi, I’d be very concerned, because the vaccination rate is low. So there, I’d keep a mask on my child and keep social distancing. If I lived in Massachusetts, I might breathe a little easier,” she said.

Mississippi’s vaccination rate trails the national average. As of Monday, 37% of residents had received at least one dose, and 33% were fully vaccinated, according to the CDC, compared with 71% of people in Massachusetts who’ve gotten at least one shot and 63% who are fully vaccinated.

Your child doesn’t need to wear a mask in most outdoor settings because the risk of transmission is low, Flores noted, but it’s a good idea to have them wear one in indoor public spaces, especially if ventilation is poor or if the space is crowded.

The same fundamental practices the CDC recommends for schools, like handwashing and social distancing, are useful for reducing kids’ risk in non-school settings. You can also model wearing a mask for your child, even if you’re vaccinated and don’t technically need one yourself. If you’re not going to wear a mask around your child, having a conversation as a family explaining why masks are important is key, Flores suggested.

“This is an added protection for you. Just like I would put a seatbelt on you, I would put a mask on you for this time,” she said. “Kids understand seatbelts.”
