COVID: New sub-variant BA.2.3 accounts for 20% of new cases

(ANSA) - ROME, APR 13 - The new COVID-19 sub-variant BA.2. 3 currently accounts for around 20% of new coronavirus cases being reported in Italy, geneticist and Naples university COVID task force coordinator Massimo Zollo told ANSA Wednesday.
    He said BA.2.3 "originated from the BA.2 sub-variant but has more mutations than it does".
    The new strain originally descends from BA.1. said Zollo.
    He added that since March 1 Italy had filed some 10,000 virus sequences in international COVID-19 mapping data banks. (ANSA).
