New data from the Centers for Disease Control and Prevention shows activity of COVID-19 is increasing across a wide swath of the country.
As the U.S. approaches the midpoint of summer, the CDC is reporting cases of the virus are growing or likely growing in more than half of all states, including many in the South and Southeast.
The center’s July 18 report shows at least 26 states plus Washington, D.C., are encountering a summer surge, according to its epidemic trend modeling, using data from emergency department visits. The CDC notes its modeling indicates trends in overall cases, not the actual numbers of current infections.
