COVID-19, the disease caused by the novel coronavirus that first appeared in Wuhan, China in late 2019, reached San Diego County in mid-March, just as the World Health Organization declared it a pandemic.

This data is not a full representation of cases. Totals are based on patients' resident zip code, and are not a representation of where someone contracted COVID-19. Because not every single resident is tested regularly, officials with the County Health and Human Services Agency say the number of people infected with COVID-19 in the county is likely much higher than the reported total.
Other Data: Is San Diego County "flattening the curve?"; COVID-19 case totals by age and gender; Map of case totals by city of residence; Case totals by race/ethnicity; Tests reported by day; Statistics regarding hospitalized patients.
