A research by the microbiology laboratory of the Civil hospital of Brescia highlighted a less aggressive version of the coronavirus. To announce it to “Fourth degree” is Arnaldo Caruso, the president of the Italian Virology Society who explains: “The first isolated virus we had was very aggressive. After a long time, we found this second weaker version. ”
The discovery was made possible thanks to the swab performed on an asymptomatic but high viral load patient. Other virologists, however, warn that the different behavior of the virus could depend on the characteristics of the host and not on its weakening.
