The counties of San Francisco and San Mateo fall purple

The counties of San Francisco and San Mateo have been classified as “purple” in the state’s reopening plan from Saturday. Marin County is the only Bay Area county to remain in the “red” (significant spread) layer.

San Francisco, Mayor of London Breed, announced Saturday afternoon through social media, called the latest COVID-19 data, “SF’s more aggressive surge to date”

“We are currently averaging 118 new cases a day, compared to 73 a day in the first week of November,” Breed wrote in his tweet series. “We had 768 diagnosed cases in the week of November 16, compared to 217 cases diagnosed in the week of October 12.”

At noon on Sunday, Breed announced that retail stores, including shopping malls and core retail businesses, should cut indoor capacity to 25 percent. This does not include stand-alone grocery stores, which can still operate at 50 percent capacity.

Outdoor entertainment attractions such as carousels and ferris wheels, as well as indoor movie theaters, indoor gyms and fitness centers, indoor museums, aquariums and zoos, should be closed.

San Francisco will begin the state’s restricted home residence policy Monday through 10 p.m., and will ban various households from gathering indoors and outdoors from 10 p.m. to 5 p.m., Dec. 21, Breed he continued.

County San Mateo has also stated that it will follow a home stay order in California beginning at 10 p.m., Monday.

According to the county announcement, the county of San Mateo reported an increase of about 85 percent in new COVID-19 cases from October to November. The county’s newly adjusted case ratio is now 7.6 / 100,000 inhabitants.

“We haven’t seen numbers like this in a long time, and we really need to reverse this incredibly worrying trend,” county chief Mike Callagy said in a county statement. “It’s important to note that we can reverse the trend as long as we follow common sense health and safety practices.”

The state system divides the counties into four counties – “purple” (widespread), “red” (significant), “orange” (moderate), or “yellow” (minimal) – which measures the prevalence of COVID-19 and what types it dictates. businesses and activities are open. The structure allows counties to be more restrictive and move more slowly than when the state is reopened, if desired.

The determination of the county level is based on two key indicators: the number of cases (number of new cases per 100,000 inhabitants) and the positivity rate (the percentage of individuals tested is positive for the virus). is also part of the equation, but only plays a role in helping a county move to a less restrictive level.

Counties in the purple category report more than seven new daily cases per 100,000 inhabitants, with a positivity rate of over 8%. In order for a county to be included in the red level, it must report less than seven cases per 100,000 inhabitants per day and report a test positivity rate of less than 8% for 14 consecutive days. The orange level requires less than 3.9 cases per 100,000 and the test positivity is below 4.9%, and the yellow requires less than one case at 100,000 and is less than 2% positive.
