Omicron variant, who strikes and how: the first data from South Africa

How contagious is it really and who most affects the Omicron variant? Now they are starting to filter the first data that begin to better frame this umpteenth mutation which, according to virologists, is destined to replace the Delta in a short time. Its contagiousness, in fact, is considered very high and although a few more days of observation will be needed, scientists are already able to provide interesting data on Omicron’s propagation capacity and above all on how serious it is in terms of effects.
