Doctors in Wuhan, China where the virus emerged reported that between 3 and 10% of cured patients became reinfected with the illness, though it’s unclear whether they were contagious for the second time.

Tongji Hospital, which identified the first COVID-19 case, confirmed that five of 145 patients — a little over 3% — tested positive again in nucleic acid tests, according to state broadcaster CCTV.

So far there is no evidence to suggest that they are infectious,” said Wang Wei, the hospital’s president.

He said the five patients who tested positive again did not have any symptoms and none of their close contacts had been infected.

Wang added that surveillance of similar patients showed that 80 to 90% had no trace of the virus in their system one month after being discharged from the hospital, according to the report.

But, he said, these are just “small samples” and “not enough to assure us of the validity of our initial findings.”

“We need a large-scale epidemiological study to guide our disease surveillance and prevention works,” Wang said.

Meanwhile, other quarantine facilities in Wuhan have seen about 5 to 10% of their recovered patients test positive again.

The studies come as health officials around the world are testing the concept of taking plasma from someone who has been infected, processing it and injecting the antibodies into a sick person to stimulate their immune system.

Meanwhile, there is fear in China that there may be a second coronavirus outbreak in the country, only weeks after the country had recovered from their first Covid-19 outbreak.

People in Hubei, the first epicenter of the pandemic have been allowed to leave the province for the first time in two months, following a sixty-day lockdown. With the threat of a new outbreak, Chinese residents may be forced to go back into lockdown.

Currently, there is no cure/vaccine for Covid-19, even though many of the people that contract the virus recover from it, they don’t become immune to the virus. You can contact the coronavirus multiple times.

The mortality rate may be relatively low, but without a working vaccine Covid-19 is unlikely to go away.

Leaders all over the world have been pleading with citizens to take this pandemic very seriously.

There is over Five-thousand confirmed cases of Covid-19 worldwide and that number is increasing every day. It will be a long time until the world can go back to normal.
