Key coronavirus forecast predicts over 410,000 total U.S. deaths by Jan. 1

The U.S. will top more than 410,000 Covid-19 deaths by the end of the year as the country heads into the fall and winter, according to a new forecast from the Institute for Health Metrics and Evaluation at the University of Washington.

Covid-19 has already killed at least 186,800 people in the U.S., according to data compiled by Johns Hopkins University. The model by IHME, whose models have previously been cited by the White House and state officials, forecasts that the death toll will more than double by Jan. 1 and could reach as high as 620,000 if states continue to ease coronavirus restrictions.

“The worst is yet to come. I don’t think perhaps that’s a surprise, although I think there’s a natural tendency as we’re a little bit in the Northern hemisphere summer, to think maybe the epidemic is going away,” Dr. Christopher Murray, director of IHME, told reporters on a conference call Friday.

IHME released three projections based on different assumptions: a worst-case scenario, a best-case scenario and a most likely scenario. The most likely scenario estimates that Covid-19 will kill 410,450 people in the U.S. by Jan. 1. The worst-case scenario, which assumes that restrictions and mask directives will ease, projects up to 620,028 people in the U.S. will die by then and the best-case scenario, which assumes universal masking, predicts that 288,380 people in the U.S. will die from Covid-19 in 2020.

“We are facing the prospect of a deadly December, especially in Europe, Central Asia, and the United States,” Murray said in a statement. “But the science is clear and the evidence irrefutable: mask-wearing, social distancing, and limits to social gatherings are vital to helping prevent transmission of the virus.”

With widespread mask wearing and adherence to other public health guidance, the modelers estimate that more than 750,000 lives could be saved globally by Jan. 1. Covid-19 has so far killed at least 869,600 people around the world, according to Hopkins data.

IHME’s latest forecast is based on the assumption that cooler weather in the Northern hemisphere and will have people spending more time indoors where the coronavirus more easily spreads, keeping the death toll high.

“People in the Northern Hemisphere must be especially vigilant as winter approaches, since the coronavirus, like pneumonia, will be more prevalent in cold climates,” Murray said.
