Calif. is among 5 states in CDC's orange tier for substantial COVID spread
California was in the yellow and later the orange in the Centers for Disease Control and Prevention's COVID data tracker on Oct. 19, 2021.
CDCCalifornia was briefly the only U.S. state in the yellow tier Monday night into Tuesday morning in the Centers for Disease Control and Prevention's COVID Data Tracker. This level indicates "moderate" spread of the coronavirus
The state jumped back to the orange tier signaling "substantial" spread Tuesday afternoon. Connecticut, Florida, Hawaii and Louisiana were also in the orange Tuesday. Most other states across the country were in the red tier indicating "high" transmission with more than 100 total new cases per 100,000 in the last week.
The CDC's tracker uses the latest data to report on the severity of the COVID pandemic in each state. The Monday map is reportedly unreliable, especially for California as the state often lags in providing its weekend data.
"CDPH is aware of this data issue associated with the CDC COVID Data Tracker and has been working closely with CDC to correct it," the California Department of Public Health said in a statement to SFGATE. "For part of Mondays and Tuesdays for the last several weeks, CDC has shown California as being in the “yellow/moderate transmission” category and then has switched to show California as in the “orange/substantial transmission” category later on Tuesday. This problem appears to be linked to California’s 5 day/week reporting cadence. CDC has notified CDPH that they will be implementing a change in their system to accommodate the CDPH reporting cadence."
The CDC's tracker also assigns tier levels to counties in all 50 states, and counties in the Bay Area were generally seeing lower community transmission than the rest of the country. Contra Costa, Napa, San Francisco, Santa Clara, Solano, Sonoma were all in the orange on Tuesday. Alameda, Marin, San Mateo were in the yellow.
Eight counties — all except Solano — in the Bay Area are using the tier levels as one factor in determining whether a county can fully lift its mask mandate.
A county must reach the "moderate" (yellow) tier of case rates, as determined by the Centers for Disease Control and Prevention's data tracker, and remain there for three weeks.
The counties set two other criteria to lift the mask mandate. One, 80% of a county's total population must be fully vaccinated against COVID-19, or eight weeks removed from when the COVID-19 vaccine has been authorized for children ages 5 to 11. Marin is the only county in the Bay Area to meet this criteria and as of Tuesday 81% of its population was fully vaccinated.
Secondly, a county's health officer must determine that COVID-19 hospitalizations are "low and stable." In Marin, the only county that's close to meeting the criteria to end the mandate, Dr. Matt Willis, the county's health director has set the metric for when hospitalizations are at a point where it's safe to end the mask rules..
"Last week, there were 15 total COVID-19 hospitalizations in Marin," Willis said last week. "So we set that as the metric — we’ll want to see less than 15 people in the hospital for COVID-19 before lifting the mandate."
