How low exactly is COVID-19 transmission in the San Francisco Bay Area right now? – SFGate

While the COVID-19 pandemic is surging in other places across the country, cases and deaths in California are declining and the San Francisco Bay Area is doing especially well. But exactly how low are the rates of transmission in the nine-county region?

The well-vaccinated region is generally doing better than the rest of the state. Here's a look at the seven-day positivity rate, seven-day average of cases per 100,000 people and seven-day average of deaths per 100,000, respectively, for California and each of the counties as of Sept. 16 based on the state's dashboard.

California: 3.4% test positivity (seven-day rate), 20.0 cases per 100,000 (seven-day average), 0.2 deaths per 100,000 (seven-day average)Alameda: 2.3% test positivity, 11.1 cases per 100,000, 0.01 deaths per 100,000Contra Costa: 3.2% test positivity, 15.2 cases per 100,000, 0.2 deaths per 100,000Marin: 2.1% test positivity, 8.3 cases per 100,000, 0 deaths per 100,000Napa: 3.8% test positivity, 18.8 cases per 100,000, 0.2 deaths per 100,000San Francisco: 2.0% positivity, 10.1 cases per 100,000, 0.2 deaths per 100,000San Mateo: 1.9% test positivity, 9.5 cases per 100,000, 0.04 deaths per 100,000Santa Clara: 1.7% test positivity, 11.3 cases per 100,000, 0.1 deaths per 100,000Solano: 4.1% test positivity, 19.9 cases per 100,000, 0.4 deaths per 100,000Sonoma: 2.6% test positivity, 13.2 cases per 100,000, 0.1 deaths per 100,000

The numbers are all headed in a downward direction and inching toward where the state and Bay Area were in June, when the pandemic saw a lull just before the state reopened for business and lifted most restrictions June 15. On June 2, the state was recording an average of 2.1 cases per 100,000 and 0.04 deaths per 100,000 across seven days. On June 1, the seven-day positivity rate was 0.8%.

The Bay Area has had some of the tightest COVID restrictions in the country. All counties in the region mandate masks indoors except Solano.

San Francisco and Berkeley require proof of vaccination to enter indoor bars, restaurants, clubs, gyms and large indoor events. Customers under age 12 are exempt. A negative COVID-19 test is not a substitute. Contra Costa County on Tuesday issued a similar mandate for entering indoor restaurants, bars and gyms though both proof of full vaccination or a negative coronavirus test are acceptable.

CDC released this map of the current seven-day case rate for the percent of tests returning positive for COVID-19.

The Centers for Disease Control and Prevention's COVID Data Tracker map also provides an overview of how counties are doing; the map is based on a county's moving seven-day number of new COVID-19 cases and COVID-19 test positivity percentage.

The severity of the pandemic in each county is represented by four tier levels: high, substantial, moderate and low.

In the San Francisco Bay Area, Marin, San Francisco, San Mateo, Santa Clara and Alameda are all in the substantial tier as of Sept. 16. Contra Costa, Napa, Solano and Sonoma are in the high. Just to the south of the Bay Area, Monterey and Santa Cruz are substantial.

The rest of the state is mostly a sea of red except for a few counties with low transmission: Lassen, Modoc, Mono and Sierra.While the center of California is a sea of red with the majority of counties seeing a high level of COVID-19 community transmission
