Abstract
We retrieved data from the on-line database of the Italian Ministry of Health concerning the previous and ongoing epidemic waves of SARS-CoV-2 in Italy, analyzing prevalence of variants, number of SARS-CoV-2 diagnoses, hospitalization and intensive care unit (ICU) admissions for coronavirus disease 2019 (COVID-19). Two similar days were compared, i.e., January 12, 2021 and January 12, 2022. Although the number of positive cases in 2022 was hence nearly 4-fold higher compared to the same period in 2021, presumably due to higher transmissibility of the Omicron variant, a considerable decrease of COVID-19 related hospitalizations (-82%) and ICU admissions (-84%) could be observed in the more recent period, when the Omicron variant was largely prevalent and COVID-19 vaccination was widespread.
