The local COVID-19 adjusted case rate has steadily increased and has reached 7.0 cases per every 100,000 residents, placing the County in danger of being moved into the state’s more restrictive Purple Tier or Tier 1.

Should the case rate reach 7.1 or higher for two consecutive weeks, indoor activities will not be allowed at restaurants, movie theaters, gyms and a number of other locations.

County health officials are asking San Diegans to be vigilant and continue following the local health guidance to slow the spread of the novel coronavirus.

“San Diegans must take action and do it now. We need everyone’s support so that we can prevent the region from moving into the most restrictive level,” said Wilma Wooten, M.D., M.P.H., County public health officer. “People should stay home as much as possible, telework if they can and avoid gatherings to prevent the spread of COVID-19.”

The County’s COVID-19 unadjusted case rate for the week of Oct. 4 through Oct. 10 increased from 7.2 to 7.8. The adjusted metric also rose from 6.8 to 7.0 cases per 100,000 people during the same time.

Should the region post Purple Tier numbers for two weeks in a row, the County would be forced to follow the more restrictive state guidance.

“We must bring our numbers down and the only way to do that is to limit our contact with people outside our households,” Wooten said. “San Diegans who need to be out in public should wear a mask and maintain their distance from people outside their household. Avoid large crowds or gatherings to prevent getting or passing the virus.”

Given the data reported for the week of Oct. 4 through Oct. 10, the County is expected to still be in the Red Tier when the state announces the region new standing Oct. 20.

State Metrics:
