High testing rate keeps San Diego in red tier as cases continue to rise


SAN DIEGO (CNS) – Despite an adjusted daily COVID-19 case rate of 7 per 100,000 population, San Diego County was again able to avoid being pushed into the most restrictive purple tier of California’s four-tier reopening system Tuesday.

High rates of testing helped the county stay in the red tier, county officials said. The positive adjustment is given by the state to counties that are testing at higher levels than the state’s median. That adjustment prevented the county from data which would have landed it in purple, which would have placed indoor activities at restaurants, movie theaters, gyms and a number of other locations in jeopardy.

“Remaining in the red tier is good news, but the new adjusted rate is not. The new figure clearly shows the region is not moving in the right direction,” said Dr. Wilma Wooten, San Diego County public health officer. “It is extremely important San Diegans follow the local health guidance to slow the spread of COVID-19 and keep the region from falling into the purple tier.”

The county’s unadjusted case rate for the week of Oct. 4-10 rose from 7.2 to 7.8 cases per 100,000 residents. It was adjusted down to 7 per 100,000. The data are reported on a one-week delay.

While the testing positivity percentage for the region also increased from 3% to 3.3%, it still remains low enough for this metric to remain in the orange tier. If a county reports statistics meeting metrics in a higher tier for two consecutive weeks, it will move into that more restrictive tier for a minimum of three weeks.

The state’s health equity metric, which looks at the testing positivity for areas with the lowest healthy conditions, dropped from 5.7 to 5.5% and remained in the red tier. This metric does not move counties backward to more restrictive tiers, but is required to advance.

County public health officials reported 265 new COVID-19 infections and four deaths related to the illness Tuesday, raising the region’s total case count to 53,000 and the death toll to 857.

Four men died between Oct. 11 and Oct. 18, and their ages ranged from mid-50s to early 80s. All had underlying medical conditions.

Of the 9,110 tests reported Tuesday, 3% returned positive, bringing the 14-day rolling average percentage of positive cases to 2.8%, far below the state-set target of less than 8%.

Of the total COVID-19 cases in the county, 3,788 or 7.1% have been hospitalized, with 876 — or 1.7% — spending at least some time in an intensive care unit.

Five new community outbreaks were reported Tuesday, two is businesses, one in a restaurant/bar setting, on in K-12 school setting and one in a faith-based setting. In the past seven days, 30 community outbreaks were confirmed, well above the trigger of seven or more in a week’s time.

A community outbreak is defined as three or more COVID-19 cases in a setting and in people of different households over the past 14 days.

The county uses community outbreaks to get a larger sense of the pandemic locally, but the state does not include the statistic in its weekly report.

Wooten said 95% of the county’s cases were not related to a marked community outbreak, a clear indicator the illness has spread throughout the county.
