New IHME Forecasts Show More Than 200,000 US Deaths by November 1

SEATTLE, July 7, 2020 /PRNewswire/ -- In its first projections of COVID-19 deaths out to November 1, the Institute for Health Metrics and Evaluation (IHME) at the University of Washington is forecasting more than 200,000 deaths in the United States. 

The forecast shows 208,255 deaths (with a range of 186,087 to 244,541). Those numbers drop to 162,808 (157,217 to 171,193), if at least 95% of people wear masks in public.

"We can now see the projected trajectory of the epidemic into the fall, and many states are expected to experience significant increases in cases and deaths in September and October," said IHME Director Dr. Christopher Murray. "However, as we all have come to recognize, wearing masks can substantially reduce transmission of the virus. Mask mandates delay the need for re-imposing closures of businesses and have huge economic benefits. Moreover, those who refuse masks are putting their lives, their families, their friends, and their communities at risk."

IHME's new projections include the re-imposition of strong social distancing mandates when deaths per day reach a level of 8 per one million people, comparing that with a forecast if no action is taken, and a forecast if social distancing mandates are combined with at least 95% mask wearing in public spaces. Florida and Massachusetts 17,472 (11,275 to 32,577) and 12,906 (11,017 to 16,873), respectively, are expected to reach 8 per million deaths by November 1. The forecast for Florida, which is expected to reach 8 per million deaths on October 1, differs by 6,173 deaths if the state does not re-impose social distancing mandates. If mask wearing reaches 95%, that number drops to 9,849 (7,921 to 14,052).

The projections may increase if the current surge in infections spreads more widely in at-risk populations. Current data from states reporting the age breakdown of cases suggest that more cases are being detected in young people, who have a lower risk of death.

The forecasts also show deaths beginning to increase again in many states in mid- to late September, due to the expected seasonality of COVID-19. Current data show a strong statistical relationship between COVID-19 transmission and pneumonia seasonality, which is included as a covariate in the model.

"The US didn't experience a true end to the first wave of the pandemic," Murray said. "This will not spare us from a second surge in the fall, which will hit particularly hard in states currently seeing high levels of infections."

IHME will continue to forecast for different scenarios, including planned intermittent mandates in the fall when deaths per day are expected to reach higher levels within each state, recognizing that solutions are not uniform across communities.
