As Stay at Home Order Lifts, COVID-19 Testing Remains One of the Most Important Tools in Pandemic Response

Jan. 30, 2021

Testing opportunities will be available this week in San José, Gilroy, Los Altos Hills, Mountain View, Cupertino, Campbell, and Palo Alto

Santa Clara County, CA - As the Stay at Home Order was lifted statewide last week, public health officials in Santa Clara County remind residents to continue vigilantly testing for COVID-19. It remains one of the most important tools in the pandemic response, especially now that more activities are resuming while community transmission of the virus remains high.

“Since the Stay at Home Order has been lifted, some activities with high risk of exposure will resume so it is more important than ever to be mindful of our actions to keep our communities, friends, and families safe,” said Dr. Marty Fenstersheib, COVID-19 Testing and Vaccine Officer for the County of Santa Clara. “Mask up, keep your distance, and get tested regularly if you are at risk of exposure. These public health measures are still our best tools.”

Testing opportunities are being continually expanded, rotating to new neighborhoods each week. Mobile testing buses will be offering appointment-based testing in San José, Campbell, and Gilroy this upcoming week. Drop-in testing may be accommodated if space allows. Appointment-based testing continues seven days a week at the Santa Clara County Fairgrounds, along with standing walk-in sites in San José and Gilroy. Rotating appointment-only city sites next week will be in Los Altos, Mountain View, Cupertino, Campbell, and Palo Alto.

Appointments can be made starting seven days in advance of the testing date until all slots are reserved at Appointment-based testing is also available in San José at the Fairgrounds, with appointments now available five days in advance. Testing is free at all these sites. Appointments are essential for reserving a testing slot.

The County would like to remind people that hospital emergency departments are not the appropriate venue for a COVID-19 test when symptoms are not present and there is no emergency medical issue. Emergency Departments are for people who need emergency care and are currently very busy caring for patients with urgent medical needs.

The County test sites provide COVID-19 tests free of charge, regardless of immigration status, and no doctor’s note is needed. At some County test sites, people with insurance may be asked to provide their insurance information, so that payment from the insurance company can be collected. However, patients won’t be billed for any co-pay, deductible, or any other cost for testing. Those without health insurance or those who do not provide insurance information can still get a test at those sites.

For people without COVID-19 symptoms, the County currently offers indoor and drive-through sites. People with symptoms are directed to drive-through sites to reduce the chance of getting others sick.

For those with healthcare coverage, systems such as Kaiser Permanente, Sutter/Palo Alto Medical Foundation and others are required by County order to offer free testing to symptomatic persons, persons who have been exposed to a confirmed COVID-19 case, and all “essential workers.” Examples of “essential workers” include teachers, healthcare workers, grocery store clerks, and persons who work in agriculture or food manufacturing.

For more information on testing rights, see our Frequently Asked Questions page. The County also collects and publishes data on testing by large healthcare systems:

All test sites are mapped on the County’s website at The site is available in English, Spanish, Vietnamese, Chinese, and Tagalog. Information is also available by calling 2-1-1.
