COVID-19, the disease caused by a novel coronavirus first identified in late December in Wuhan, China, is now spreading in the US. The map and charts below will update automatically with the latest data compiled by researchers at Johns Hopkins University.

This map shows confirmed cases of COVID-19, relative to their populations. On Jan. 20, the CDC confirmed the first US case, a 35-year-old man in Snohomish County, Washington, who had recently traveled to Wuhan. Since then, cases have been confirmed across the country.

The intensity of color on this map will in large part reflect the extent to which different states have rolled out testing for the virus. New York has so far led the way.

This chart shows the cumulative total of confirmed cases in the US. There may be many more cases going undetected, however.

New confirmed cases in the US by day

This plot of new cases diagnosed by day shows what experts call the β€œepidemic curve.” As a disease outbreak continues, the number of new cases rises over time and then may fall as the outbreak is controlled or naturally declines. That has not yet happened with COVID-19 in the US.

You can also use this COVID-19 tracker to compare the US outbreak with those in other countries.

In addition to regularly updating the data in the charts and maps, this post will be updated with other information as it becomes available.
