96% of nearly 3,300 inmates with coronavirus were asymptomatic, survey shows

96% of 3,277 inmates in state prison systems in Arkansas, North Carolina, Ohio and Virginia who tested positive for the coronavirus did not show symptoms, Reuters reports.

Why it matters: The findings suggest that asymptomatic patients could be contributing to the spread of the virus at a far higher level than suspected, especially in prisons, which have proven to be a breeding ground for COVID-19 in the U.S.

  • This is especially noteworthy because health officials have prioritized testing and surveillance for people that show symptoms. 4,693 total tests were conducted.
  • “It adds to the understanding that we have a severe undercount of cases in the U.S.,” Leana Wen, adjunct associate professor of emergency medicine at George Washington University, told Reuters.

The big picture: Two prisons — Marion Correctional Institute in Ohio and Chicago's Cook County jail — are among the largest known sources of coronavirus infections in the U.S.

  • At Marion, close to 95% of the 2,028 inmates who tested positive for the virus were asymptomatic, according to Reuters.

Mass protests in Atlanta, New York City and Washington, D.C., sparked clashes with police on Friday, as demonstrators demanded justice for the death of George Floyd, a black man who died after at least one police officer knelt on his neck on Monday.

The big picture: The officer involved in the killing of Floyd was charged with third-degree murder on Friday, after protests continued in Minneapolis for three days.

Zuckerberg says Trump’s “shooting” tweet didn’t violate Facebook’s rules

Facebook did not remove President Trump's threat to send the National Guard to Minneapolis because the company's policy on inciting violence allows discussion on state use of force, CEO Mark Zuckerberg explained in a post on Friday.

The big picture: Zuckerberg's statement comes on the heels of leaked internal criticism from Facebook employees over how the company handled Trump's posts about the Minneapolis protests and his unsubstantiated claims on mail-in ballots — both of which Twitter has now taken action on.
