Many areas of the South "that have been rapidly reopening their economies are in danger of a second wave of coronavirus infections over the next four weeks, according to a research team that uses cellphone data to track social mobility and forecast the trajectory of the pandemic," The Washington Post reports.

"The model, developed by ­PolicyLab at Children’s Hospital of Philadelphia and updated Wednesday with new data, suggests that most communities in the United States should be able to avoid a second spike in the near term if residents are careful to maintain social distancing even as businesses open up and restrictions are eased."

Anthony Fauci, director of the National Institute for Allergy and Infectious Diseases, told the Post this week that he has no doubt there will be a second wave of cases this fall, and that the nation should take this time to prepare for it.
