A group of researchers at the Scripps Research Institute in La Jolla, California, said they had identified the first case of a person twice infected with the coronavirus in the United States. It is not the first time that similar episodes have been reported, but news of this type must be contextualized and taken with caution, and does not deny the shared thesis that an immunity to the coronavirus develops after being infected with it.

The American case concerns a 25-year-old man from Nevada who tested positive for the first time in April, showing mild symptoms of COVID-19: After testing negative, he had more severe symptoms again in May and turned positive. to the pad. Researchers from the University of Nevada, Reno School of Medicine and the Nevada State Public Health Laboratory said they isolated the viruses responsible for the two infections, verifying that it was two separate events and not a relapse.
It is news that must be taken with great caution: the American researchers announced it in a statement, waiting for their discovery to undergo the necessary review process for scientific publications. A few days ago, in the same way, a group of Hong Kong researchers had presented a similar investigation, documenting another case of reinfection. But similar cases reported so far in the world have been few and far between, due to the many things that we still do not know about our body’s immune response to the coronavirus and must be studied further before reaching conclusions.
Currently, there is optimism among scientists studying COVID-19 that the human body develops immunity against the coronavirus, as confirmed by many studies and research so far. Immunity, however, is a more complex concept than one might intuitively think: “it’s never 100 percent,” the US researchers said.
