COVID Live Updates: Some Walgreens And CVS Stores Close As Staff Battle Omicron

A new study from UK scientists suggests some who test positive for COVID-19 could be contagious for longer than 10 days.

Researchers at the University of Exeter conducted the study on a group of 176 people, all tested positive for the virus on standard PCR tests.

The study found 13 percent of patients, or about 1 in 10, had "clinically-relevant levels" of the virus after 10 days, meaning they could still be infectious.

"In some settings, such as people returning to care homes after illness, people continuing to be infectious after ten days could pose a serious public health risk," University of Exeter Medical School lead author Merlin Davies said.

"We may need to ensure people in those setting(s) have a negative active virus test to ensure people are no longer infectious. We now want to conduct larger trials to investigate this further."

The test used in the study only gives a positive result when the virus is active and potentially capable of ''onward transmission.''

In comparison, conventional PCR tests work by testing for the presence of viral fragments. The findings explain these tests can tell if an individual has recently had COVID-19 but cannot determine if the virus is still active or if the person is infectious.
