The US Centers for Disease Control and Prevention has said that the coronavirus could be a prolonged illness, even among young adults without underlying chronic medical conditions.
About 35 per cent 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. The results were reported in the CDC’s Morbidity and Mortality Weekly Report.
Of those surveyed, 94 per cent said they had at least one symptom when they went in for a Covid-19 test.
People reported having a median number of seven of the 17 symptoms listed by the CDC.
Fatigue was the most common complaint, followed by cough and a headache.
For the people whose symptoms lingered, 43 per cent said they had a cough, 35 per cent said they felt tired, and 29 per cent said they were short of breath.
The median time that they had been interviewed was 16 days from when they tested positive.
65 per cent of those surveyed said they had returned to their usual state of health five to 12 days after they had a positive Covid-19 test.
Age seemed to play a role in whether someone still felt sick weeks after a positive test.
More of the people in the 50-and-older demographic, 47 per cent said they still had symptoms weeks after their test.
By comparison, among people ages 18 to 34, 26 per cent said they still had symptoms. For people in the 35-to-49 age range, 32 per cent said they still weren’t back to full health.
The more chronic conditions someone had, the more likely it was that they still had lingering symptoms.
But even 1 in 5 younger people ages 18 to 34 who had no chronic medical conditions said they had not fully recovered.
Earlier studies have shown that hospitalized patients can have lengthy recovery times.
One survey of patients in Italy done two months after they became ill, found that more than 87 per cent still had at least one symptom and more than half said they still had three or more symptoms.
Some doctors expressed concerns that the symptoms could linger for years and some may never fully recover.
There are studies underway to gauge the long-term effects and some clinics have started to set up programs that help people with long-term Covid-19 symptoms.
