(CNN) – An influential model tracking the coronavirus pandemic in the United States now predicts that fewer people will die and fewer hospital beds will be needed compared to its estimates from last week.
As of Monday, the model predicted the virus will kill 81,766 people in the United States over the next four months, with just under 141,000 hospital beds being needed. That’s about 12,000 fewer deaths — and 121,000 fewer hospital beds — than the model estimated on Thursday. 
A “massive infusion of new data” led to the adjustments, according to the model’s maker, Dr. Christopher Murray, who serves as director of the Institute for Health Metrics and Evaluation at the University of Washington School of Medicine.
Additional data on the pandemic’s trajectory — in the United States and around the world — has always been expected, along with methodological changes to fine-tune the predictions. And from the start, researchers at IHME, who built the model, have emphasized that it would change.
But the newest version of the model underscores just how important social distancing continues to be: It assumes that those measures — such as closing schools and businesses — will continue until August, and it still predicts tens of thousands of deaths.
While the analysis has been repeatedly cited by Dr. Deborah Birx, the White House’s coronavirus response coordinator, the administration’s current guidelines only recommend social distancing through April 30.
