The rate of Covid hospitalization in intensive care is equal to 26.7 per 100 thousand for the unvaccinated and 0.7 per 100 thousand for vaccinated with full cycle plus additional dose / booster: 38 times higher. This is one of the data emerging from the extended report of the Higher Institute of Health on the progress of the Covid-19 epidemic in Italy.
REINFECTIONS – “From August 24, 2021”, the day in which Covid reinfection cases were included in the daily data stream, “as of January 12, 2022, 70,629 cases of reinfection” by Sars-CoV-2 were notified, “equal to 2, 5% of the total number of cases reported (total first diagnoses since 24 August) “. In particular, “up to 13 December each week, reinfections represented about 1% of the total number of notified cases”. With the spread of Omicron, more capable of ‘breaking’ immunity than Delta, the percentage has risen and yet, “although the figure is still in the consolidation phase, in the last week the percentage of reinfections (3.3% ) out of the total number of cases reported is stable compared to the previous week (3.1%) “.
“The probability of contracting a reinfection – underlines the ISS – is higher in the unvaccinated than in those vaccinated with at least one dose, and in health workers compared to the rest of the population”.
BOOSTER – “In subjects vaccinated with an additional dose / booster, the effectiveness in preventing the diagnosis of” Covid-19 “and cases of severe disease is respectively 68.8% and 98%” underlines the Higher Institute of Health, in the extended report on the progress of the epidemic in Italy.
“The effectiveness of the vaccine (risk reduction compared to non-vaccinated people) in preventing the diagnosis of Sars-CoV-2 infection – details the ISS – is equal to 71% within 90 days of the completion of the vaccination cycle, 57% among 91 and 120 days, and 34% beyond 120 days. Vaccination efficacy in preventing cases of severe disease remains high: 95% in vaccinated with a full course of less than 90 days, 93% in vaccinated with a full course of 91 and 120 days and 89% in the vaccinated who have completed the vaccination cycle for more than 120 days “.
DEATH – “During the period 27 December 2021-9 January 2022, 1,701,009 new cases were reported, of which 1,004 died” for Covid-19. A value, the latter, which “does not include the people who died in the period with a diagnosis prior to December 27”, reads the report.
The ISS reports a “strong delay in notification in the last week. In particular, the number of cases notified by the Regions of Calabria, Friuli Venezia Giulia, Sardinia, Sicily, Tuscany and the Autonomous Province of Bolzano are affected by a strong delay of notification due to technical-organizational difficulties and strong pressure on health services “.
STRONG INCREASE IN CASES IN 16-19 YEARS AND ADMISSIONS TO UNDER 5 – “In the last week there is an increase in the incidence” of Covid-19 “in all age groups” from 0 to 19 “compared to the previous week: in particular, the incidence in the population aged 12- 19 years is equal to 2,489 cases per 100 thousand vs 1,840 cases per 100 thousand in the previous week. In the age group 5-11 years, starting from the second week of October, there is a greater increase in the incidence compared to the rest of the aged population. In the last 2 weeks there has been a sharp increase in the incidence in particular for the 16-19 age group and a sharp increase in the hospitalization rate in the less than 5 year group (more than 10 hospitalizations per million inhabitants) , and a smaller increase in the 16-19 age group “.
“In the last week – it continues – the percentage of cases reported in the school age population remains stable (20%). 31% of school age cases were diagnosed in the 5-11 age group, 59 % in the 12-19 age group and only 10% in children under 5 “.
Overall, “from the beginning of the epidemic to 12 January, 1,403,640 confirmed cases of which 37 died were reported to the integrated Covid-19 surveillance system in the population 0-19 years old”. As for the “period 27 December 2021 – 9 January 2022, 340,005 new cases were reported in this population, of which 1,245 hospitalized, 14 hospitalized in intensive care and one death (the reported values do not include hospitalized people, hospitalized in intensive care and deaths diagnosed before December 27) “.
INFECTIONS BETWEEN HEALTHCARE – “The percentage of cases” of Covid-19 “in health care workers, out of the total number of cases reported, is slightly down from 2.0% in the previous week to 1.8%” it is highlighted.
Infections among healthcare professionals, which decreased after the start of the administration of the booster doses of the vaccine, had marked an increase in the last 2 weeks, in which the diffusion of the Omicron variant has increased.
