“Today in Italy we only have the Omicron” variant of the covid “which has overwhelmed Delta, and has probably reached 100%.” Thus to Adnkronos Salute Mauro Pistello, director of the Virology Unit of the University Hospital of Pisa, vice president of the Italian Society of Microbiology and one of the founders of the sequencing network of the Higher Institute of Health, anticipating the results of the new survey of the Higher Institute of health care. The latest, dated 28 January, with the data collected on 17 January, reports Omicron at 95.8%.
“It must be said that in our laboratory we had to analyze a percentage of the first new cases on January 31, but the incidence is much lower – explains Pistello – so the cases we analyzed are 50 against the 80 studied on January 17 for the last. survey. At that time on the territory of Tuscany that we are considering, we had found two cases of Omicron 2, while this time we did not find it. Just as we did not detect other variants or sub-variants “.
On the question of the high number of deaths that still occur in Italy and whether they can still be attributed to Delta or are the effect of Omicron, the virologist hypothesizes that “there is a patchy situation, Delta has reduced and is almost disappeared early, but in some areas of the country this passage is slower and therefore – he concludes – some deaths from Covid that are recorded today could be a Delta queue “.
