How California turned the tide, achieved lowest coronavirus transmission rate in US
LOS ANGELES — A few months ago, it looked as if California’s long-awaited reopening following massive coronavirus closures might be derailed by the highly contagious delta variant.
Cases shot up in many areas, and then hospitals began to fill again.
There was a summer surge, but the curve has begun to flatten in many parts of California, which now has the lowest coronavirus case rate of any state in the nation.
How did this happen?
While California has not reinstituted the sort of sweeping restrictions seen earlier in the pandemic, the state — along with many local health departments and other systems — has taken steps to tackle the delta variant.
Notably, Los Angeles County reimposed a mandate in mid-July requiring all residents, regardless of vaccination status, to wear face coverings in public indoor places. A number of other counties have since followed suit.
Those who have yet to be vaccinated against COVID-19 must wear masks in indoor public settings throughout California, though state officials continue to only recommend — not require — that fully vaccinated people do likewise.
Some parts of the state also require that residents show they’ve either been vaccinated or recently tested negative before patronizing certain businesses or venues.
Statewide, such vaccine-or-testing proof is required for all attendees of indoor events with at least 1,000 people, according to the California Department of Public Health.
Other areas have gone further. In L.A. County, participants and workers at outdoor events with more than 10,000 attendees will need to provide proof of vaccination or show they’ve recently tested negative for the coronavirus, starting Oct. 7.
That requirement also applies to stadiums and large theme parks.
Proof of COVID-19 vaccination will also be required at indoor bars, wineries, breweries, nightclubs and lounges in L.A. County starting next month.
L.A. isn’t alone. San Francisco and Berkeley require customers 12 and older in indoor restaurants, bars and gyms to show proof of a COVID-19 vaccination. Contra Costa County has ordered those customers to show either proof of vaccination or a recent negative coronavirus test result. Palm Springs and neighboring Cathedral City have ordered patrons 12 and older to provide proof of COVID-19 vaccination or a recent negative coronavirus test to enter indoor restaurants and bars.
Given the protective power afforded by the vaccines, health officials have expanded the pool of people required to get shots.
California has ordered that healthcare workers statewide must be fully vaccinated against COVID-19. School employees also must be vaccinated or submit to at least a weekly coronavirus test.
Some cities and counties are also requiring their municipal employees to get vaccinated or tested regularly, and some individual businesses are doing likewise.
It’s not just workers, either. All children 12 and older in Los Angeles public schools also will have to be fully vaccinated by January.
Officials believe these types of measures helped slow the spread of the virus and also encouraged more people to get vaccinated.
What about vaccinations?
California has higher vaccination rates than some states hard hit by the summer surge.
Officials say unvaccinated Californians continue to be infected at higher rates than their vaccinated counterparts.
During the week of Aug. 29 through Sept. 4, the average case rate among unvaccinated individuals was roughly eight times higher than for those who had been inoculated, according to the California Department of Public Health.
Almost 66% of Californians have received at least one dose of COVID-19 vaccine. But the rates vary widely by community.
In 11 of the state’s 58 counties, more than 70% of residents have received at least one shot to date, according to data compiled by The Times. However, 14 other counties have yet to partially inoculate even half of their population.
Unvaccinated people are also at far greater risk of being hospitalized. Of the hundreds admitted to L.A. County’s public hospital system since June 15 for a diagnosis primarily linked to COVID-19, 93% have been unvaccinated.
Where does California stand now?
As of Monday, California’s seven-day case rate was 95.3 per 100,000 people. The next-closest state was Connecticut, at 126.5.
The comparable rates over the same period were 385.1 cases per 100,000 people in Texas; 287.2 in Florida; 250.1 in Arizona; 234.7 in Oregon; and 202.5 in Nevada, federal data show.
The Centers for Disease Control and Prevention categorizes states’ coronavirus transmission levels in four tiers: the worst — high — is color-coded as red, followed by substantial (orange), moderate (yellow) and low (blue).
