Tests conducted in patients who were discharged from the hospital about a month ago showed that the re-infection rate is from 3% to 10%. At the same time, it is not completely clear how the virus appeared again in their organisms – either it remained inside and during their discharge from the hospital, or they became infected again.
At the same time, doctors from Tongji Hospital in Wuhan, the first to detect the disease, claim that there is no evidence so far that patients who again had a positive result for coronavirus became infectious to healthy people. To do this, scientists constantly check their family members.
The publication also notes that positive results on coronavirus can also speak about the problems of the nucleic acid test, which simply detected traces of viruses in some recovered patients. In addition, antibodies were found in their blood that effectively protected the body from the nucleic acid of the virus.
Nevertheless, all patients who are discharged from hospitals need to spend at least a few more weeks in quarantine at home, doctors say. Patients who again have found traces of coronavirus in their blood will be re-hospitalized.
To confirm whether it is possible to get COVID-19 coronavirus infection again and infect other people, many similar studies have to be done, scientists say.
In addition, many international organizations note that now in Wuhan, the quality of the diagnosis of coronavirus infection and the quarantine condition in which patients are kept has sharply decreased.
