San Diego County public health officials have reported 143 new COVID-19 infections and three virus-related deaths, raising the cumulative caseload to 51,470 and the number of fatalities to 847, amid a rise in confirmed community outbreaks.
One woman and two men died between Oct. 2-14, and their ages ranged from early 70s to late 80s. All had underlying medical conditions, according to the county Health & Human Services Agency.
Of the 8,315 tests reported Thursday, 2% returned positive, keeping the 14-day rolling average percentage of positive cases at 3%. The seven-day daily average of tests was 10,100.
Of the total number of cases in the county, 3,720 — or 7.2% — have required hospitalization and 862 — or 1.7% of all cases — had to be admitted to an intensive care unit. There are currently 233 COVID-19 patients in the region's hospitals; 72 of them in ICUs.
A total of 17 new community outbreaks were reported Thursday — 10 in business settings, three in restaurant/bar settings, two in faith-based institutions, one in a food processing setting and one in a restaurant.
In the past seven days, 47 community outbreaks were confirmed, well above the trigger of seven or more in a week's time. A community setting 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 outbreak to get a larger sense of the pandemic locally, but the state does not include the statistic in its weekly report.
On Tuesday, state data confirmed the county will remain in the red, or substantial, tier of the state's four-tier COVID-19 reopening plan for at least another week.
County Supervisors Greg Cox and Nathan Fletcher said staying in red wasn't good enough. Cox said the red tier's restrictions still made it incredibly difficult for small businesses to stay open.
Fletcher agreed, saying the county needed to drive down positive tests and new case numbers.
"The overwhelming majority (of county residents) are doing everything right, but we need to see numbers go down," he said. "We need to get off this weekly cliff we stare down."
For several consecutive weeks, the county has remained in the red tier, but within very close range of the most restrictive purple tier, which would shutter almost all indoor businesses.
The California Department of Public Health reported Tuesday that San Diego County's state-calculated, adjusted case rate is 6.8 daily infections per 100,000 residents, up from 6.5 the previous week. The unadjusted case rate is 7.2, up from 6.9 last Tuesday. The adjusted rate is due to San Diego County's high volume of tests.
The testing positivity percentage is 3%, below last week's 3.5%, and is in the third — or orange — tier.
To remain in the second tier of the four-tier COVID-19 reopening plan, the county must continue to have an adjusted case rate of less than 7.0 per 100,000 residents and a testing positivity percentage of less than 5%.
The county is preparing additional health and safety guidelines as the school year moves forward, county Public Health Officer Dr. Wilma Wooten said Wednesday. A survey of the San Diego County Office of Education found that of the 42 school districts, 27 are reopen to at least some students for in- person learning, six will open later this month, three have a target date of January 2021, one is looking for a start date in October or November and two are still determining a start date.
Another metric the state released Tuesday is the health equity metric, which finds the positivity rate of the county's least healthy quartile. San Diego County's health equity is 5.7%, slightly less than double the county's positive testing average.
The metric will be used to determine how quickly a county may advance through the reopening plan.
Counties with a large disparity between the least and most sick members of a community will not be punished for the disparity by sliding back into more restrictive tiers, but such a disparity will stop counties from advancing to less-restrictive tiers.
To advance to the orange tier, the county would need to report a metric of less than 5.3%.
According to the state guidelines, the health equity metric will measure socially determined health circumstances, such as a community's transportation, housing, access to health care and testing, access to healthy food and parks.
Neighborhoods are grouped and scored by census tracts on the Healthy Places Index, healthyplacesindex.org.
The California Department of Public Health will update the county's data next Tuesday.
