The viral load is rising to very high levels, that is the number of copies of the genetic material of the new coronavirus present in a milliliter of biological material taken with the swab, so much so that "in 80% of positive cases it is now over one million" virologist Francesco Broccolo, from the Milan Bicocca University and director of the Cerba laboratory in Milan, told ANSA.
"Very often - he added - the viral load is even higher, up to billions in asymptomatic or symptomatic subjects between 30 and 60 years of age". The data indicates that the infections are recent: "a very high viral load - Broccolo noted - is an indication of a new active infection". That is, it indicates that "the infection is recent and primary, that is, it has not persisted for months".
