COVID-19 forecasting


Nicholas Reich has been on the forefront of analyzing models that forecast infectious diseases, including COVID-19. His work has been featured in publications around the world, including the New York Times, Science magazine and Foreign Policy.

Reich runs the UMass-based CDC Influenza Forecasting Center of Excellence, one of two in the nation. It has produced some of the world’s most accurate models in recent years, In April 2020 he developed a COVID-19 forecasting hub that unified multiple models in an effort to produce a more accurate picture of the potential impacts of the novel coronavirus. These forecasts were used by the Centers for Disease Control and Prevention and helped inform the public health response to the pandemic.

The outside group of modelers that the Centers for Disease Control and Prevention relies on to forecast trends in the virus are also planning to continue producing their projections with the agency. "We do expect to continue running COVID hospitalization and likely death forecasts too for perhaps at least another year. Case forecasts I'm not as sure about," saod Nicholas Reich, professor of biostatistics at the University of Massachusetts.

Nicholas Reich comments about the current state of COVID-19. He says, "We’ve seen COVID hospitalizations increase to around 5,000 new admissions each day from just over 1,000 in early April. But deaths due to COVID have only increased slightly over the same time period."

New White House Covid projection puzzles experts and catches some Biden officials off guard

CNN  tv


Nicholas Reich comments on the White House's latest COVID projection that the U.S. could see 100 million new COVID infections in the fall and winter if Congress doesn’t approve additional funding to fight the pandemic. Reich says, “It's an outcome that we should be thinking about and preparing for. Does it mean it's absolutely going to happen? No.”

With 60% of Americans vaccinated, Nicholas Reich says, “I wouldn't be surprised if we kept at a slow burn trajectory over the winter. I wouldn't be surprised if we continued to decline, if the childhood vaccinations really were able to help continue to push the curve down, and I wouldn't be surprised if we saw continued growth.”

The Pandemic’s Lethal Twilight

New York Magazine  print


At a time when about 40,000 people per day were getting sick, modelers forecast that that rate would hold steady for the next four weeks. Instead, infections soared past 105,000 per day and kept climbing into the new year. “We’ve seen the limitations of what these models can do,” says Nick Reich, a professor of biostatistics and epidemiology at UMass Amherst. “At these moments of change, unfortunately, they have not been as accurate at these moments where we really want them to be.”

‘Flu-like’ data might help track coronavirus spread. Why did Florida stop publishing it?

“In times like this, not having that raw data easily available to researchers limits our ability to analyze and report effectively on emerging trends of respiratory infections in Florida,” said Nicholas Reich, a professor of biostatistics and epidemiology at the University of Massachusetts Amherst.

“It seems that the press has been eager to push the narrative of ‘we are near the peak!’ and ‘the end is in sight,’ but given the strong uncertainty about the future and lack of clear consensus among modelers, I think these messages are premature,” UMass infectious disease researcher Nicholas Reich argued.
