This dataset provides the daily & cumulative number of COVID-19 new confirmed cases, hospitalizations, and deaths among Marin County residents (does not include San Quentin inmates). Event Date corresponds to date that each status type occurred. For Confirmed Case this is Test Date, for Hospitalized this is Hospital Admit Date, and for Death it is the Date of Death. If a person first tested positive for COVID-19 on 11/1/2020, was admitted to the hospital on 11/15/2020, and died on 11/20/2020, their data would be contained in three rows for each status and event date.

Cases are lab-confirmed COVID-19 cases reported to Marin County Public Health by providers, commercial laboratories, and academic laboratories, including reporting results through the California Reportable Disease Information Exchange. A lab-confirmed case is defined as detection of SARS-CoV-2 RNA in a clinical specimen using a molecular amplification detection test.
