The weekly incidence at a national level slightly rises: it marks 34 cases per 100 thousand inhabitants in the survey conducted by ISS and the Ministry of Health on behalf of the control room from 15 to 21 October 2021 against 29 cases per 100 thousand inhabitants in the previous week. However, the incidence remains below the weekly threshold of 50 cases per 100 thousand inhabitants which could allow the control of transmission based on the containment or identification of cases and the tracing of their contacts.
Rt slightly up to 0.86
In the period from 29 September to 12 October 2021, the mean Rt calculated on symptomatic cases was equal to 0.86 (range 0.82 – 0.90), below the epidemic threshold, but slightly increased compared to the week previous. Slightly increases the transmissibility index based on cases with hospitalization (Rt = 0.89 (0.84-0.93) at 12/10/2021 vs Rt = 0.83 (0.78-0.88) at 5/10/2021).
Slight decline for intensive care and medical areas
The employment rate in intensive care is slightly down to 3.7%. The employment rate in medical areas nationwide falls to 4.2 percent.
Four regions at moderate risk
Four regions are classified at moderate risk: Abruzzo, Campania, Friuli Venezia Giulia and Piedmont. The other regions and autonomous provinces are classified as low risk. One reports a resilience alert. None reports multiple resilience alerts.
New cases not associated with transmission chains are increasing
The number of new cases not associated with transmission chains is increasing: 4,759 against 4,551 the previous week. The percentage of cases detected through contact tracing activity is slightly down (33% versus 34% last week). On the other hand, the percentage of cases detected through the appearance of symptoms is slightly increasing (48% against 47%). The percentage of cases diagnosed through screening activities remains stable (19% versus 19%).
