NEW YORK- A 33-year-old man was diagnosed with coronavirus for the second time, more than four months after his first infection. However, he has not experienced any symptoms this time around. This shows that his body has created some sort of immune response to the virus that has allowed him to feel completely normal. Although he is asymptomatic, he is still able to spread it to many people, which is obviously the issue. Doctors around the world are saying this is a textbook example of how immunity works.
This man had no antibodies after his first infection, but had them after his second bout. He then received another test after traveling to Europe and it showed he had been infected with a strand of the virus that had been circulating in that region. Scientists believe he was infected with different 'versions' of the virus. It is still unclear how common it is for someone to be reinfected and what that reinfection might look like for different people. Researchers also say that it is possible to have a worse reaction at the time of second infection.
Experts still do not know how often a person can become reinfected and how soon after the first diagnosis they are able to be infected and test positive.
