Scientists from Hong Kong clinically confirmed the world’s first case of reinfection of Covid-19, so preventive measures will begin to be taken, to check how immunity to the virus works, in addition to controlling new strains of coronavirus if they are developing.
The reinfected patient is a 33-year-old man, who first contracted the disease in April, after traveling to Spain. His case was asymptomatic and he had a normal recovery. However, four months after contracting the disease, he has tested positive again, but with a clinical picture completely different, depending on the doctors who treat you.
Scientists studying this reinfection by coronavirus point out that:
“Many believe that patients recovered from COVID-19 they have immunity against reinfections because most developed a response based on neutralizing antibodies in serum. He SARS-CoV-2 could persist in the human population, as is the case with other common human coronaviruses associated with colds, even though patients have gained immunity through a natural infection“
With this, how the coronavirus immunity acts is studied SARS-CoV-2, causing the Covid-19Although it has been believed to be a long-term protective immunity, it may only last for a few months. This means, at the same time, that during this period of time and towards the end of the year we will be able to check if this is the case in case reinfections soar as infections did at the time.
This could also indicate that the virus is mutating and finding new infection mechanisms, which would make handling much more dangerous. epidemiological of the crisis that we are currently facing; therefore, the health authorities of Hong Kong and China they began to expand security measures for all people who at the time contracted the disease.
