The sub-variant Omicron 2 is "30% more contagious than Omicron, it approaches measles and chickenpox but those who have the triple dose are protected from severe forms.
Unfortunately, those who had Covid with the Omicron wave in December can get reinfected today, we are talking about a 10% share ".
The director of IRCSS Galeazzi in Milan, Fabrizio Pregliasco, tells Rai Radio1, guest of Un Giorno da Pecora.
As for the hypothesis that the current one can be considered as a new pandemic wave, it is, explains Pregliasco, the "wave of a more peaceful virus, let's say that more than a fifth wave is a rise of the fourth".
