According to the study, published in the American Journal of Preventive Medicine, close to 17 per cent of patients considered fully recovered from Covid-19 tested positive for the virus in follow-up screening.
This suggests the persistence of these two symptoms should not be underestimated and should be adequately assessed in all patients considered recovered from Covid-19.
The only two symptoms that were higher and significantly prevalent in patients with a positive test were sore throat (18 per cent vs four per cent) and signs of rhinitis (27 per cent vs two per cent).
