Indeed, the news is very worrying. According to reports
As a result, a growing number of coronavirus patients discharged from China and other parts of the world are reinfecting themselves after recovering from the disease, in some cases weeks after leaving the hospital, a situation that could make it difficult to eradicate the epidemic.
In late February, Osaka Prefecture in Japan reported that a woman working as a tour bus guide tested positive for the coronavirus for the second time. The case came after China reported that some patients discharged from the country were becoming ill again after leaving the hospital.
One such case occurred in the city of Xuzhou, where a father and daughter were readmitted after being released from hospital two weeks earlier. With news of the return of positive healings, Wuhan, the epicentre of Covid-19, is now imposing a 14-day solitary confinement on those who claim to be cured.
However, an official from China’s National Health Commission said on February 28 that these patients had not been considered infectious.
The possible reasons
Experts say there are many ways that discharged patients can get the same virus. Convalescing people may not have enough antibodies to develop immunity and are becoming infected again.
in China have been attributed to discrepancies in laboratory tests.
On February 21, a patient who was discharged from a health center in the Chinese city of Chengdu was readmitted 10 days later after testing positive in a follow-up exam.
Song Tie, deputy director of the Guangdong disease control center in southern China, said at a news conference that up to 14 percent of patients discharged from the province tested positive again and had returned to hospitals for observation.
He added, however, that a good sign is that none of those patients appear to have infected anyone else.
Normally, convalescent patients will develop specific antibodies that make them immune to the virus that infected them, but reinfection is not impossible, said Adam Kamradt-Scott, an infectious disease specialist at the University of Sydney.
He said Kamradt-Scott.
So far, China has released more than 70 percent of the 80,000 infected patients, according to WHO data released a week ago. If the 14% re-infection rate is accurate and remains constant, this could pose a significant public health risk.
