Uncontrolled coronavirus spread continuing in 24 states, study estimates

The Washington Post reports:

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.

It is a snapshot of a transitional moment in the pandemic and captures the patchwork nature across the country of covid-19, the disease caused by the virus. Some states have had little viral spread or “crushed the curve” to a great degree and have some wiggle room to reopen their economies without generating a new epidemic-level surge in cases. Others are nowhere near containing the virus.

The model, which has not been peer reviewed, shows that in the majority of states, a second wave looms if people abandon efforts to mitigate the viral spread.

“There’s evidence that the U.S. is not under control, as an entire country,” said Samir Bhatt, a senior lecturer in geostatistics at Imperial College.

The model shows potentially ominous scenarios if people move around as they did previously and do so without taking precautions. In California and Florida, the death rate could spike to roughly 1,000 a day by July without efforts to mitigate the spread, according to the report. [Continue reading…]
