Social distancing a week earlier could have saved 36,000 American lives, study says

On March 8, it was mostly business as usual in the United States. As the Lakers faced the Clippers in a much-anticipated Los Angeles basketball matchup, Sen. Bernie Sanders (I-Vt.) rallied before a packed crowd in Michigan. In Miami, thousands squeezed onto the beach for a massive dance party. With 500 coronavirus infections reported nationwide at the time, the outbreak seemed like a distant threat to many Americans.





But by the following Sunday, the nation had entered a different universe: 2,000 confirmed cases, dozens of deaths, and shutdown orders in Illinois, Ohio and New York City, among other parts of the country. What if those sweeping measures imposed by March 15 — a federal warning against large gatherings, health screenings at airports, states of emergency declared by governors and mayors — had been announced a week earlier?


New research from Columbia University epidemiologists offered one possible answer on Wednesday. If the same kind of social distancing had been in place seven days earlier, their study found, the United States could have prevented 36,000 deaths through early May — about 40 percent of fatalities reported to date.


“If you don’t take steps to fight the growth rate aggressively, you get much worse consequences,” Jeffrey Shaman, an environmental health sciences professor who led the study, told The Washington Post.


His team’s analysis used infectious-disease modeling to examine the spread of the virus from March 15, when many people nationwide began staying home, until May 3. The researchers examined transmissions within each county, movement between counties and deaths to chart how the virus spread — and killed — over seven weeks.
