New Imperial College Research Estimates Coronavirus Still Spreading Uncontrolled in 24 US States

The coronavirus may still be spreading at epidemic rates in 24 states, particularly in the South and Midwest, according to new research that highlights the risk of a second wave of infections in places that reopen too quickly or without sufficient precautions.

Researchers at Imperial College London created a model that incorporates cellphone data showing that people sharply reduced their movements after stay-at-home orders were broadly imposed in March. With restrictions now easing and mobility increasing with the approach of Memorial Day and the unofficial start of summer, the researchers developed an estimate of viral spread as of May 17.
