Up to 10 per cent of recovered virus patients in Wuhan study test positive
Hospital staff in the city say there is no evidence that these patients became infectious after recovery. Tests carried out on patients suggest between 3 to 10 per cent gave positive tests after being discharged.
About 3 to 10 per cent of patients who recovered from Covid-19 tested positive again after being discharged from hospital, doctors in Wuhan have found.
Researchers around the world are trying to determine whether recovered patients can still infect people with the coronavirus that causes the disease and if they have developed antibodies offering them immunity to the disease.
Doctors from Tongji hospital in the city, where the disease was first identified, told state broadcaster CCTV that they have found no evidence that these patients who again tested positive became infectious , based on close observations of their family members and laboratory tests.
In spite of its relatively small sample size, the Tongji hospital research is especially relevant as China now has far more recovered patients than new confirmed cases.
