Stringent social distancing measures imposed by state and local governments in the U.S. led to slower spread of the coronavirus, according to a new study in Health Affairs.

Why it matters: One of the most effective measures was COVID-19 shelter-in-place orders, which many states are lifting before public health experts say is safe.

Details: The study examined the impact of several social distancing measures.

  • It found that government-imposed shelter-in-place orders and closures of entertainment venues, gyms, bars, and restaurant dining areas had a significant impact on the spread of the virus.
  • But the study didn't find evidence that school closures or large event bans had an impact on spread.

The big picture: "Holding the amount of voluntary social distancing constant, these results imply 10 times greater spread by April 27 without [shelter in place orders] (10 million cases) and more than 35 times greater spread without any of the four measures (35 million)," the authors write.

President Trump said during an interview with conservative radio host Hugh Hewitt Tuesday he'd love to hold campaign rallies, but he "can't because of the covid. ... you can't have people sitting next to each other."

Why it matters: Trump is known for electrifying crowds at rallies and connecting with loyal supporters on a huge scale. But Trump stressed to Hewitt and in a separate radio interview earlier Tuesday that it wouldn't work while social distancing is required to prevent the spread of COVID-19. "You can’t have empty seats," Trump told with Fox News Radio.
