O BSH gives a clarification to patients who recover from COVID-19 and then are tested positive again

The declared recovered coronary patients, who later test positive, are still rooting out dead lung cells rather than contracting a new infection, broadcast news.net.

South Korean health authorities raised concerns about the coronary after reporting more than 300 cases of restored patients later tested positive.

If survivors of COVIDD-19 can reinfect the virus, it can complicate efforts to remove quarantine restrictions and produce a vaccine.

But such test results seem to be fake slides caused by remaining lung cells, but probably not infectious, and left out of the material.

For some viruses, such as measles, those who contract it are immune to life, while other coronarys such as SARS, immunity lasted from several months to two years, reports the Daily Mail. People infected with SARS-CoV-2 virus causing COVID-19 are building antibodies starting a week or more after infection or the beginning of symptoms, research has shown.

But it is still not clear whether the body builds enough immunity to remove a new attack from the virus, or if it happens, how long such immunity lasts.

O The BSH also said that more research is needed for recovering patients who initially tested negative and then tested positive later.
