According to professor and physician Matteo Bassetti, director of infectious diseases at the General Hospital of San Martino in Genoa, Italy, “the virus changes in severity.” Italian expert says that “the coronavirus is weakened and can die alone without a vaccine”.
In his words, the coronavirus, once an “aggressive tiger” of a disease, has weakened and become more of a “wild cat.”
For the researcher, this may be due to a genetic mutation in the virus that makes it less lethal, due to improved treatments or due to people not being infected by such large doses due to social distance.

Professor Bassetti suggests that one of the reasons why the virus can cause less serious illness is a genetic mutation that has made it less harmful to human lungs.
“The clinical impression I have is that the virus changes in severity,” says the expert.
“In March and early April, the patterns were completely different. “People came to the emergency room with a very difficult illness to deal with and needed oxygen and ventilation, some developed pneumonia and now, in the last four weeks, the picture has changed completely in terms of patterns,” he adds.
But other researchers have responded to allegations in the past, saying there is no scientific evidence that the virus has changed at all.
