July 10, 2021 The percentage of genotyped cases of Covid-19 is up from around 0.5% in January to 6% in June. This is the data contained in the variant bulletin announced yesterday by the president of the Higher Institute of Health (Iss), Silvio Brusaferro, who highlighted that in Italy "the Alfa variant remains dominant" but "the Kappa and Delta variant are today at 27, 7% and the Gamma or Brazilian variant also remains in circulation at around 12% ".
