After testing negative twice in a row, a coronavirus patient in Wuhan ” the former epicenter of the coronavirus outbreak ” was discharged recently from one of China™s mobile hospital units.
But her celebration of freedom had barely begun before she got a call from the local health authority who told her the last test she took before leaving the hospital was positive.
œI had to go back to the hospital immediately, the patient said on Weibo, China™s Twitter-like platform. œMy residential compound is under lockdown again.
As China releases more patients who have recovered from the coronavirus, there are an increasing number who are testing positive for the second time. The State Council ™s Joint Prevention and Control Mechanism said last Saturday that second-time infections have been reported in many regions, including Guangdong, Sichuan, Hunan, and Hubei province, where Wuhan is the capital city.
It is not understood why some patients test positive after testing negative.
But most virologists believe true second-time infections are extremely rare. Recovered patients have high amounts of antibodies in their blood that fought off the COVID-19 infection, protecting them against a recurrence. That is why in many countries recovered patients are now donating blood plasma for transfusions into sick patients.
Another explanation for the positive tests could be inaccurate testing.
