Our finds suggest that SARS-CoV-2 may persist in humans, as is the case for other common cold-associated human coronaviruses, even if patients have acquired immunity via natural infection or via vaccination," the researchers told CNN.A man living in Hong Kong has been infected by the novel coronavirus for the second time, according to a research by the University of Hong Kong."Natural infection created immunity that prevented disease but not reinfection," she said.Cases of presumed reinfection have been reported previously, but none have been confirmed with rigorous testing. Recovered people are known to carry viral fragments for weeks, which can lead to positive test results in the absence of live virus.The patient is believed to the world's first documented case of reinfection by SARS-CoV-2, the virus that causes COVID-19.A man living in Hong Kong has been infected by the novel coronavirus for the second time, according to a research by the University of Hong Kong.The patient is believed to the world's first documented case of reinfection by SARS-CoV-2, the virus that causes COVID-19.The patient is believed to the world's first documented case of reinfection by SARS-CoV-2, the virus that causes COVID-19.The patient is believed to the world's first documented case of reinfection by SARS-CoV-2, the virus that causes COVID-19."Patients with a previous COVID-19 infection should also comply with epidemiological control measures such as universal masking and social distancing," they said."Patients with a previous COVID-19 infection should also comply with epidemiological control measures such as universal masking and social distancing," they said....The findings also show that people who have had coronavirus already should nonetheless get vaccinated if and when a vaccine becomes available, the researchers was quoted as saying.-˽˰ģء΢10596229-
