Some Covid Patients Could Spread Virus After 10 Days, Study Says

  • Research comes as England cuts isolation period to five days
  • Study tested patients in 2020 when first strain was dominant

Some people with Covid were able to transmit the virus to others after the 10-day mark, at least in the early days of the pandemic, a new U.K. study shows.

That’s according to research by the University of Exeter, which used an adapted test that can detect whether the virus remains active in those with previously confirmed infections. It found that 13% of 176 people studied had levels high enough to be potentially infectious even after 10 days.
