San Joaquin County COVID-19 cases continue to surge at a rapid pace as of Tuesday, county health officials said.

In a presentation to the county’s Board of Supervisors, county Public Health Officer Maggie Park said the county’s case rate as of Tuesday is 87.8 per 100,000 people, up from 45.7 the previous week.

“With the omicron variant mixed in with some delta still hanging around, we have far surpassed the peak of last winter’s surge and passed the peak of the summer surge we just got through,” Park said.

As of Tuesday, the county has also reported a testing positivity rate of 28.1 percent, up from 21.8 percent last week.

Data from San Joaquin County’s Public Health Services showed that since last Wednesday, there have been 17 new deaths related to COVID-19, and 156 people were hospitalized with COVID in the county as of Tuesday.

Due to high testing demands, the county has opened one new testing site and increased operating hours at two other locations.

People can now receive COVID-19 testing at the San Joaquin County Agricultural Center located at 2101 E. Earhart Ave. from 9 a.m. to 4 p.m. Mondays through Fridays.

Hours for testing have also been expanded at 19 S. Central Ave. in Lodi, and at San Joaquin General Hospital.

Additional testing sites opening soon will be at the Lodi Grape Festival grounds and the San Joaquin Delta College Mountain House campus.
