Coronavirus: Tracking And Mapping Cases

The coronavirus pandemic has spread rapidly across the world with the United States leading in the total number of positive cases and deaths. California, being the largest state, leads the nation in both cases and deaths.

Here in San Diego County, more than 37,000 people have tested positive for the virus and more than 600 people have died.

To help better see the spread of the virus in San Diego County, KPBS has compiled COVID-19 data into the following visualizations:

The San Diego County Health and Human Services Agency releases COVID-19 data daily about new cases and the latest deaths. However, there can sometimes be delays due to testing backlogs.

Though Mexico is behind the United States in terms of total number of coronavirus cases, the pandemic has hit the country hard. The country currently ranks among the top ten in total numbers of cases.

In July, San Diego County was added to the state's COVID-19 monitoring list. At that time, the county was averaging more than the state's threshold of 100 cases per 100,000 people.

On August 19, Gov. Newsom removed San Diego County from the monitoring list once the local case rate dropped to 88.4 positive COVID-19 tests per 100,000 people.

The county can be placed back on that list if its flagged for exceeding any one of six different metrics the state takes into account when placing counties on the list. They include everything from the case rate, the percentage of positive tests, the average number of tests a county is able to perform daily, changes in the number of hospitalized patients and the percentage of ventilators and intensive care beds available.

KPBS has mapped out COVID-19 cases across the regions using San Diego County data, which gets updated daily.

The data represents the residence of the person who was infected, not the site of transmission. County health officials have frequently stressed that they don't want the public to read too much into the data because the numbers only represent a portion of actual COVID-19 cases.
