Follow the latest data on COVID-19 cases and deaths in the US.
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.
US cases by location
This map shows locations in the US that have confirmed cases of COVID-19, scaled by the number of cases in each place. On Jan. 20, the CDC confirmed the first US case of COVID-19, a 35-year-old man in Snohomish County, Washington, who had recently traveled to Wuhan. Since then, cases have been confirmed across the country, with the largest outbreaks in California, New York, and Washington state.
Total confirmed US cases and deaths
This chart shows the number of confirmed cases in the US over time, divided into patients who are still sick, those who have recovered, and those who have died. These numbers are still small compared to the totals overseas, with the largest death tolls seen in China, Italy, and Iran.
Total confirmed US cases
This chart shows the cumulative total of confirmed cases in the US. There may be many more cases going undetected, however, because relatively few people have so far been tested for the virus. In Washington, the worst-affected state so far, the virus is believed to have been circulating for weeks before the outbreak was recognized.
New cases in the US by day
This plot of new cases diagnosed by day shows what experts call the “epidemic 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. New cases are expected to rise dramatically in the coming weeks as the US begins widespread testing for the disease.
