LA County Brings Back Mask Mandate Indoors — Even If You're Vaccinated

A rapid and sustained increase in COVID-19 cases in the nation's largest county requires restoring an indoor mask mandate even when people are vaccinated, Los Angeles County's public health officer said Thursday.

Dr. Muntu Davis said at a virtual press conference that a public health order requiring masks indoors will go into effect Saturday.

"This is an all-hands-on-deck moment," he said.

Davis didn't fully detail what he said would be some exceptions but said for example, people could still go out to eat and take off their masks only while eating and drinking.

The county has been recording more than 1,000 new cases each day for a week, and there is now "substantial community transmission," Davis said.

San Francisco Encouraging Vaccinations

San Francisco city officials released a statement Thursday, shortly after LA County's indoor masking announcement, encouraging residents to get vaccinated as the delta variant of COVID-19 is spreading in the region.

All Bay Area counties have seen at least a doubling of new COVID-19 cases over the last three weeks, according to the statement.

“In particular, the Black community has the lowest vaccination rate compared to the citywide rate, which means more people who are already struggling with significant disparities in this City might get sick," Mayor London Breed said in the statement.

As of July 13, 83% of people ages 12 and older in San Francisco have received at least one dose and 76% are fully vaccinated.

Average daily new cases of COVID-19 have increased four-fold from mid-June to early July. The city recorded 9.9 new cases per day on June 19 which jumped to 42 new cases per day on July 7. The city estimates that number will increase to at least 73 new cases per day this week.

“As we have seen since the beginning of the pandemic, COVID-19 infections are not distributed evenly throughout all neighborhoods and communities in San Francisco,” said Dr. Grant Colfax, Director of Health for the City and County of San Francisco, in the statement.

“Bayview-Hunters Point is still one of the hardest hit areas with COVID-19 infections, particularly in the African American community. With the new delta variant that is more transmissible, it is critical that our community gets vaccinated as soon as possible,” said Shamann Walton, President of the Board of Supervisors, in the statement.

A Shelter Has Been Hit With a Cluster of Cases

Meanwhile, in Northern California, at least 59 residents at a homeless shelter have tested positive for the virus, half of whom were vaccinated, health officials said.

Of those infected at the shelter in Santa Rosa, 28 were fully vaccinated, Dr. Sundari Mase, Sonoma County's health officer, said Wednesday. Officials were reviewing an additional 26 possible positive cases.

Of the 59 people with confirmed infections at Samuel L. Jones Hall, nine were hospitalized, including six who were fully vaccinated and had "multiple, significant" underlying health conditions, including diabetes and pulmonary disease, health officials said. Four have since been discharged, and five remain hospitalized.

Officials said that fewer than half of the 153 residents had received at least partial vaccination and they do not know whether the outbreak started with a vaccinated or unvaccinated resident.

"We know congregate settings are at much higher risk," Mase said. "We also know there is a very high proportion of unvaccinated individuals that were in this setting."

Most of the 69 vaccinated residents had received the single-shot Johnson & Johnson dose but Mase said it was hard to determine whether that was a factor in the outbreak.

Vaccines Protect Against Severe COVID Consequences

Vaccines decrease the severity of the illness, reduce hospitalizations and decrease the risk of death. Clinical trials showed that a single dose of the J&J vaccine was 72% effective against moderate to severe COVID-19 in the United States, compared to 95% for the Pfizer and Moderna vaccines. A Food and Drug Administration analysis cautioned that it's not clear how well the vaccines work against each variant.

The outbreak is only the second time the coronavirus has been detected at the Sam Jones shelter. There was a smaller cluster of cases in January during the peak of the pandemic, said Jennielynn Holmes, head of homelessness services at Catholic Charities in Santa Rosa, which manages the shelter.

The shelter first became aware of the most recent outbreak on July 2, when it reported 20 positive cases.

"Something is different. This is different than what we've seen the entire pandemic," Holmes said.

Holmes and city officials had said last week the outbreak was caused by the delta variant, which is far more contagious than the original strain of the virus. County officials said they had not confirmed that and need more time to review the infections.

Clarissa Millarker, a Sam Jones resident since March, said that prior to the outbreak, shelter staff had been lax in enforcing health protocols, particularly masking.

"I feel like it's entirely likely that I'm going to turn up infected," Millarker, who is vaccinated, told The Press Democrat of Santa Rosa.

Millarker said staff have since ramped up sanitation, been more vigilant about masks and started testing every few days. Still, there is confusion and anger over how the situation was handled by shelter operators, she said.

"People are upset, and they're right to be," she said.
