Since people can transmit COVID-19 without even knowing it, testing people with and without symptoms is an important part of California’s pandemic control strategy.
“COVID-19 testing is critical to ensure prompt diagnosis, treatment and isolation to protect others,” said Heather Riden, program director of the Western Center for Agricultural Health and Safety at the University of California, Davis. “It’s especially important to regularly test people who work in close proximity to others or indoors for long periods of time.”
