Covid 19 re-infections in Italy are on the rise, supported in particular by the Omicron variants. And the people most at risk are women, the young and the unvaccinated. “In the last week, the percentage of reinfections out of the total number of reported cases was 8.4%, an increase compared to the previous week (7.5%)”. This is what emerges from the weekly extended report of the monitoring of the Higher Institute of Health (Iss) – Ministry of Health. “The analysis of the risk of reinfection starting from 6 December 2021, the date considered to be the reference date for the start of the spread of the Omicron variant, – reads the Report – highlights an increase in the ‘adjusted relative risk’ of reinfection”: in people “with the first diagnosis of Covid-19 notified for over 210 days compared to those who had the first diagnosis of Covid-19 between the previous 90 and 210 days; in people 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 “. The greater risk in women, recalls the ISS, “may probably be due to the greater presence of women in the school environment where an intense screening activity is carried out and to the fact that women more often perform the role of caregiver in the family environment. a higher risk of reinfection was also highlighted “in the younger age groups (from 12 to 49 years) compared to people with the first diagnosis between the ages of 50-59 years. Probably – indicates the ISS – 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 years “. Finally, a greater risk is found” in the health workers than the rest of the population “.
