For detailed information on specific data sets, including definitions and limitations, see the one-page narrative for the data set on the Open Data Portal.

Cases are counted by the episode date, which is calculated by California Reportable Disease Information Exchange (CalREDIE) as the earliest of the following dates (if the dates exist): date lab received, date of diagnosis, date of symptom onset, specimen collection date, or date created in CalREDIE.

Vaccination doses include data from the California Immunization Registry (CAIR) provided by Alameda County and data received from the University of California, Berkeley (UCB).
