Since recovering from an initial fight in April, a man caught the coronavirus in what scientists said was the first case which showed that reinfection could occur within a few months. On his return to Hong Kong from Europe this month, the 33-year-old ‘s second SARS-CoV-2 infection was confirmed through airport screening. Scientists at the University of Hong Kong used genomic sequence analysis to show that two separate strains infected him. The 33-Year-Old IT worker did not show any symptoms from his second infection, which may mean that subsequent infections could be milder, the researchers said.
Although some patients have been testing positive for the virus for several weeks, long after their symptoms have been resolved, scientists have not completely established whether these cases represent latent traces of the virus, a pre-eruption of an infection, or a new one. It is “the world’s first evidence of a patient healing from Covid-19 but then having another episode of Covid-19,” the researchers said in an emailed statement.
Covid-19 survivors reinfect with SARS-CoV-2 difficult to identify. It is if they do not show any signs, said Corey Smith. He is the head of translational and human immunology at the QIMR Berghofer Medical Research Institute in Brisbane.
Re-Infection Indications
One concern is that a person who reinfect can still transmit the SARS-CoV-2 virus. It is to someone who hasn’t been previously exposed. Reinfections are unavoidable, said Thomas File, president of the American Infectious Diseases Society. Also, chair of infectious diseases at Summa Health, a hospital system based in Akron, Ohio. Reinfection safety may differ among individuals and will rely on the specific patient. Thus, their immune system, whether the patient experienced symptoms of the first infection. Also, the existence of the second virus they expose to, File state in an interview Monday.
About 24 million people worldwide estimate to infect. It is with Covid-19, told reporters in Geneva Monday Maria Van Kerkhove. The technical lead of the World Health Organization on Covid-19. Some patients — including those with a mild case — install the infection with an immune response, she said.
Research that monitors large numbers of cases over time requiring to better understand the consistency. Also, durability of the neutralizing antibody response to SARS-CoV-2 in recovered patients, she said.
