More than 4 million people in the U.S. have tested positive for the coronavirus and more than 150,000 have died. Though growth in new cases slowed in late spring, by mid-June new cases began to trend upward nationally.

In the graphics below, explore the trend in new cases in your state to see whether cases are rising, falling or staying level. You can view the data via a heat map (immediately below), a curve chart and a table with details on each state's case trends over the last three weeks. Or to see states' total cases and deaths on a map, click here.

The following chart displays states' trends in new daily case counts, total cases, and per capita totals. To compare state outbreaks, the trend lines for average new daily cases are graphed against each state's total case count to date. This highlights a state's daily growth relative to the overall size of its outbreak.

As States Reopen, Do They Have The Workforce They Need To Stop Coronavirus Outbreaks?

When both new and total case counts grow quickly, the curve bends upward. As cases slow, the curve levels or bends down. In New York, site of the country's largest outbreak, the state's curve rose sharply before reaching over 170,000 total cases in April. Since then, new cases have fallen from about 10,000 per day in mid-April to under 800 per day in mid July. 

Conversely, Florida peaked around 1,200 new cases per day on average in April, only to surge again to nearly 12,000 per day in mid-July

Coronavirus case totals are much greater in some states than others. In the spring, a large share of U.S. cases were centered around New York City. As of mid July, other large, populous states such as California, Florida and Texas have reached high totals as well. Some other states such as Arizona and Louisiana show a heavy burden of infection relative to their population size.

For more detail on your state, the table below shows the change in average new cases per day in each state, week over week. States marked in shades of red are showing growth, those in shades of green, are showing declines.

Methodology

The graphics on this page pull from data compiled by the Center for Systems Science and Engineering at Johns Hopkins University from several sources, including the Centers for Disease Control and Prevention; the World Health Organization; national, state and local government health departments; 1point3acres; and local media reports. The JHU team automates its data uploads and regularly checks them for anomalies. This may result in occasional data discrepancies on this page as the JHU team resolves anomalies and updates its feeds. State-by-state recovery data are unavailable at this time. There may be discrepancies between what you see here and what you see on your local health department's website. Figures shown do not include cases on cruise ships.

In early June, Michigan health authorities started including probable cases in its totals. This resulted in a brief spike in the state's daily numbers until the JHU team was able to reconcile the historical data. On June 25, New Jersey included 1,854 previously-unreported probable deaths in its totals, resulting in a spike in the state's daily death numbers.
