How low precisely is COVID-19 transmission within the San Francisco Bay Space proper now?
As the COVID-19 pandemic increases in other locations around the country, cases and deaths are declining in California, and the San Francisco Bay Area is doing particularly well. But how low are the transfer rates in the nine-circle region exactly?
The well-vaccinated region is generally better off than the rest of the country. Here’s a look at the seven-day positivity rate, the seven-day average of cases per 100,000 people, or
California: 3.4% test positive (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 positive, 11.1 cases per 100,000, 0.01 deaths per 100,000
Contra Costa: 3.2% test positive, 15.2 cases per 100,000, 0.2 deaths per 100,000
Marin: 2.1% test positive, 8.3 cases per 100,000, 0 deaths per 100,000
Napa: 3.8% test positive, 18.8 cases per 100,000, 0.2 deaths per 100,000
San Francisco: 2.0% positivity, 10.1 cases per 100,000, 0.2 deaths per 100,000
San Mateo: 1.9% test positive, 9.5 cases per 100,000, 0.04 deaths per 100,000
Santa Clara: 1.7% test positive, 11.3 cases per 100,000, 0.1 deaths per 100,000
Solano: 4.1% test positive, 19.9 cases per 100,000, 0.4 deaths per 100,000
Sonoma: 2.6% test positive, 13.2 cases per 100,000, 0.1 deaths per 100,000
The numbers are all going down, nearing where the state and the Bay Area were in June, when the pandemic experienced a lull just before the state reopened and most restrictions were lifted on June 15, an average of 2, 1 cases per 100,000 and 0.04 deaths per 100,000 over seven days. On June 1, the 7-day positivity rate was 0.8%.
The Bay Area has some of the toughest COVID restrictions in the country. All counties in the region mandate indoor masks, with the exception of Solano.
San Francisco and Berkeley require proof of vaccination to enter indoor bars, restaurants, clubs, gyms, and large indoor events. Customers under the age of 12 are excluded. 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, although proof of full vaccination and a negative coronavirus test are both acceptable.

The Centers for Disease Control and Prevention’s COVID Data Tracker card also provides an overview of how the counties are doing. The map is based on a county’s moving seven-day number of new COVID-19 cases and the percentage of positive COVID-19 tests.
The severity of the pandemic in each county is represented by four levels: high, significant, moderate and low.

In the San Francisco Bay Area, Marin, San Francisco, San Mateo, Santa Clara, and Alameda are all in the formidable category starting September 16. Contra Costa, Napa, Solano and Sonoma are in the top group. Just south of the Bay Area are Monterey and Santa Cruz.
The rest of the state is largely a sea of red, with the exception of a few counties with low transmission: Lassen, Modoc, Mono, and Sierra. While central California is a sea of red and the majority of the counties have high levels of COVID-19 community transmission
