Covid-19 Can Be Prolonged Illness

(CNN) Covid-19 can be a prolonged illness, even among young adults without underlying chronic medical conditions, the US Centers for Disease Control and Prevention reported Friday.

Thirty-five percent of those surveyed by the agency said they still weren't back to their usual good health even two to three weeks after testing positive for the disease.

The CDC had survey results from 292 people who had a positive test for Covid-19 and were treated as an outpatient from April 15 until June 25.

The interviews were done 14 to 21 days after people were originally tested.
