The San Mateo County Health Department announces new cases and deaths each day, though bottlenecks in testing and reporting lags can introduce delays.

Experts say the true number of people infected is unknown and likely much higher than official tallies.

Cumulative cases by day

State and local officials are closely watching the latest figures as they weigh when and how to reopen. One metric is whether counties have kept the number of new cases reported over the last 14 days to less than 100 per 100,000 residents.

San Mateo County currently fails that test. Over the last two weeks, officials have confirmed 774 new cases, which amounts to 101 per 100,000.

Hospitals and patients

Lockdown measures aim to slow the virus in hope of preventing hospitals from being overrun. To keep tabs on capacity, officials watch out for rapid increases in the number of confirmed COVID-19 patients. The state asks counties with more than 20 patients to keep recent increases under 10%.

Currently, 10 of the state's 58 counties fail the test. San Mateo County meets the standard.

There are now 48 patients admitted to county hospitals with a confirmed case of COVID-19, according to the latest figures from the state. Of those, 13 are in an intensive-care unit.
