Iss: jump of the Delta variant from 5.2 in May to 27.7% in June

In Italy, “based on the data currently available, the percentage of cases” from Kappa and Delta variants (Indian family) “reported to the integrated Covid-19 surveillance increased from 5.2% in May 2021 to 27.7% in June; almost all of which are attributable to the Delta variant ». This is what we read in the report of the Higher Institute of Health «Prevalence and distribution of variants of Sars-CoV-2 of interest for public health in Italy», updated on 5 July. The report highlights the need for “great attention” to the circulation of variants. “The frequency and diffusion of cases caused by the variants Kappa (lineage B.1.617.1) and Delta (lineage B.1.617.2) is increasing – underlines the report whose key data were illustrated by ISS president Silvio Brusaferro yesterday at the Ministry of Health, during the press conference on the monitoring of the control room of the Higher Institute of Health-dicastery – These are mainly associated with limited outbreaks identified in different areas of the country “. “The variant of Sars-CoV-2 prevalent in Italy throughout the period continues to be the Alpha variant (lineage B.1.1.7), although there is a decreasing trend in percentage compared to the other variants”, notes the ISS. “The Gamma variant (lineage P.1) shows a greater diffusion in some Italian Regions / Autonomous Provinces, with an overall prevalence of 11.8% with a steady trend in the reference period”.
