The new pandemic exercise will debut in early 2021 with partners in the United States and Italy.
A new nationwide study of more than 50,000 individuals—coordinated by Columbia researchers—is now underway to determine factors that predict disease severity and long-term health impacts of COVID-19.
As politics grows increasingly polarized, a new global study finds people often exaggerate political differences and negative feelings of those on the opposite side of the political divide, and this misperception can be reduced by informing them of the other side’s true feelings. The study replicates earlier research in the United States, finding the phenomenon to be generalizable across 25 countries.
Reducing contact rates contributed to around a 70 percent reduction in the transmission of COVID-19 in New York City during the spring pandemic wave. Widespread use of face coverings contributed an additional 7 percent reduction. The study led by scientists at Columbia University Mailman School of Public Health appears in the preprint server medRxiv.

In one of the most robust studies of COVID-19 mortality risk in the United States, researchers estimate an infection fatality rate more than double estimates from other countries, with the greatest risk to older adults. Columbia University Mailman School of Public Health scientists and New York City Department of Health and Mental Hygiene colleagues published the findings on the pre-print server medRxiv ahead of peer review.
Data modeling projections by Columbia University Mailman School of Public Health scientists evaluate potential policies to reduce new infections, hospitalizations, and deaths in coming months, including by limiting school capacity by 50 percent or capping capacity of certain industries to 25 percent during Phase Four, as well as by implementing an “adaptive PAUSE” system to re-implement social distancing rules during a rebound. The researchers have been working with the New York City Department of Health and Mental Hygiene on COVID-19 planning. Their new report is posted on Github.
Columbia fertility experts have developed a one-step saliva test for COVID-19 that could expand access to testing.
A new study shows there was substantial social distancing inequalities throughout New York City during the COVID-19 pandemic. Researchers reported that areas with the lowest individual income and a greater percentage of non-white and/or Hispanic/Latino individuals, used the subway to a greater degree during the pandemic, and the strongest driver of subway use in communities of color was the percent of individuals in essential work. This is one of the first studies to assess the interrelationship between sociodemographic factors, mobility, and COVID-19. Findings are online in the preprint of medRxiv ahead of peer-reviewed publication.
New projections from Columbia University scientists find that delays in reimplementing social distancing following a relaxation of control measures could result in a stronger rebound of COVID-19 infections and deaths. If control measures had been in place earlier, a large portion of infections and deaths could have been prevented.
Lowering testosterone may prevent the new coronavirus from entering lung cells and lessen COVID-19 severity, new Columbia University research suggests. A trial has now begun in three VA hospitals.
The latest data modeling projections by Columbia University Mailman School of Public Health scientists estimate that, nationally, new COVID-19 cases and deaths will rebound in late May, as states ease stay-at-home orders and social contacts increase. By June 1, one projection scenario gives median estimates of 43,353 cases per day and 1,841 deaths per day in the United States. A second scenario with a greater progressive loosening of restrictions projects median estimates of 63,330 cases per day and 2,443 deaths per day by June 1.
Research by Columbia University Mailman School of Public Health experts finds that reinfections with endemic coronaviruses are not uncommon, even within a year of prior infection. The study on the four endemic coronaviruses—not including SARS-CoV-2, which causes COVID-19—found that when reinfection occurred, it was not associated with less severe symptoms.
