Health Officials Encourage Continued COVID-19 Testing as Rates Drop 34 Percent in the Last 2 Months

April 10, 2021

It remains critical for those at risk of exposure to get tested frequently; Testing opportunities available this upcoming week in San José, Gilroy, Sunnyvale, Morgan Hill, Santa Clara, Campbell and Palo Alto

Santa Clara County, CA - The number of people getting tested for COVID-19 has decreased in recent months, worrying health officials who remind the public that testing is critical to understanding where the region stands in the pandemic, particularly as variants continue to circulate in the community. The COVID-19 testing rate in Santa Clara County has dropped approximately 34 percent over the past two months, with the number of tests per 100,000 residents falling from a seven-day average of 958 to 632.

“If we are not testing robustly in the community, it narrows our view of where the virus is circulating, and to what level it is spreading. Testing also allows us to break the chains of transmission and reduce spread, which gives the virus less opportunities to replicate and mutate,” said Dr. Marty Fenstersheib, COVID-19 Testing and Vaccine Officer for the County of Santa Clara. “I know it feels like we are close to the end, with expanded vaccinations and many activities resuming, but let’s not drop the ball right before we cross the finish line. If you are at risk of exposure, either from work or other activities, get tested regularly.”

The County’s public health officials continue urging community members to consistently use face coverings, even if vaccinated. For those who may have been exposed to the virus, testing remains free, easy, and confidential. It is available seven days a week and there are a number of options for different needs, including appointment or drop-in, drive-through or walk-up, and specimen collection by nasal swab or saliva. Frontline workers should get tested at least once a month and up to once every two weeks, and continue testing even after being vaccinated.

Appointment-based testing continues at the Santa Clara County Fairgrounds, with rotating appointment-only city sites this upcoming week in Sunnyvale, Morgan Hill, Santa Clara, Campbell, and Palo Alto. Walk-ins continue to be accepted at standing pop-up sites in Gilroy and San José. Mobile testing buses will be in San José and Campbell.
