Please note that the dashboards displayed as of 11/22/20 reflect improvements aimed at aligning what the public can see from our County-level details with the State Blueprint metrics.  Importantly, as of today, tests reflected on the COVID-19 Lab Results Dashboard are now shown by numbers of samples rather than numbers of people tested. This shift in data reporting should NOT in any way be interpreted as reflecting a decrease in cases in the last week. San Mateo County is experiencing among the highest level of cases we have seen since the pandemic’s beginning and all our collective actions are necessary. You can see the specific trend for the past 30 days, distinct from the historical totals, by clicking on the applicable button on the Lab dashboard.

Recent data are incomplete.

This dashboard provides information on the number of COVID-19 tests administered daily in San Mateo County, including positive, negative and pending results. The health office monitors testing to ensure enough capacity to isolate those who test positive, use contact tracing to notify anyone who may have been exposed, and ultimately slow the spread of COVID-19.
