Covid today in Italy, infections in school age have been stable in the last month. This is 31% of the population according to the latest report of the Higher Institute of Health (Iss). “In the last week, 20% of school-age cases were diagnosed in children under 5, 44% in the age group 5-11, 36% in the age group 12-19”.
CASES BETWEEN 0-19 YEARS – From the beginning of the epidemic at 12 noon on 23 February 2022 “2,805,320 cases in the population 0-19 years old were diagnosed and reported to the integrated surveillance system, of which 14,544 hospitalized, 339 hospitalized in intensive care and 48 deceased“.
REINFEZIONI – “In the last week, the percentage of reinfections out of the total number of reported cases was 3.1%, a slight decrease compared to the previous week (3.2%)”. From 24 August 2021 to 23 February 2022, 232,818 cases of reinfection were reported, equal to 3% of the total cases notified. According to the ISS report, the analysis of the risk of reinfection starting from December 6, 2021, the date considered to be the reference date for the start of the spread of the Omicron variant, “highlights an increase in the adjusted relative risk of reinfection: in subjects with the first notified diagnosis for over 210 days compared to those who had the first diagnosis between 90 and 210 days previously; in subjects not vaccinated or vaccinated with at least one dose for over 120 days compared to vaccinated with at least one dose within 120 days; in females compared to males – suggests the report -. The greater risk in female subjects may probably be due to the greater presence of women in school, over 80%where an intense screening activity is carried out and the fact that women perform the role of caregiver in the family more often “.
And then “in the younger age groups (from 12 to 49 years) compared to people with the first diagnosis between the ages of 50-59. Probably the greater risk of reinfection in the younger age groups is attributable to behaviors and exposures at greater risk, compared to the age groups over 60; finally, in health workers compared to the rest of the population “.
