This dataset includes information on worksite outbreaks reported to the Santa Clara County Public Health Department. Data are updated as the County receives information that is more complete or accurate, therefore the number of outbreaks and information about each outbreak may change through this process. Please note that there is a lag in the data due to the time required for outbreaks to be investigated, closed, and the data processed.

This table contains the daily 7-day average case rates for Santa Clara County residents by age and vaccination status as well as the 7-day average case counts and population estimates to calculate these rates. Residents are considered fully vaccinated two weeks after the final dose of the vaccine, and residents are considered unvaccinated if they have not received any doses of a COVID-19 vaccine. People who are partially vaccinated are not included in either category.

Counties are experiencing temporary fluctuations in vaccination data received from the State of California due to a data reconciliation process involving integration of vaccination data systems by the State. The data reconciliation process and associated fluctuations in county vaccination are expected to be resolved by mid-April 2022

Percentage of county residents with completed COVID-19 vaccination by census tract of residence. Source: California Immunization Registry. Note: Number of people with completed vaccination is the number of county residents who either received a vaccine requiring a single dose or received the final dose of a vaccine requiring multiple doses. Percent of residents vaccinated and population age 5 years and older is based in part on estimates of the number of people residing in the census tract from a population-based survey sample, which is subject to error. As a result, percent vaccinated may be over- or under-estimated. For this reason, the displayed percent of residents vaccinated in a census tract is capped at 95%.
