Hong Kong authorities reported that a patient that had the virus and recovered on April, was reinfected. This has shown that reinfection is possible months after first exposure.
The 33 year old individual was returning back to Hong Kong from Europe. He was detected by airport screening. He did not present with any symptoms, which researchers believe that, ‘subsequent infections may be milder.’
Kwok-Yung Yuen described his findings on Monday. ‘Our findings suggest that SARS-CoV-2 may persist in humans. Even if patients have acquired immunity via natural infection or via vaccination.’
The researchers said in a statement that it is ‘the world’s first documentation of a patient who recovered from COVID-19, but got another episode of COVID-19 afterwards.’
The researchers of the University of Hong Kong said ‘Before this report, many believe that recovered COVID-19 patients have immunity against re-infection, however, there is evidence that some patients have a waning antibody level after few months.’
