Covid in Italy, Delta variant now prevalent in the country with the Rt index rising to 1.26. It also accelerates the increase in incidence, but infections are still under control. 19 Regions at moderate risk and 2 at low risk, no Region is above the critical threshold both in intensive care and in ordinary hospitalizations. Cases not associated with transmission chains are also increasing. This is what emerges from the data of the weekly monitoring of the Istituto Superiore di Sanità on the epidemiological trend of Covid-19, relating to the period 12-18 July.
The Rt index jumps at a national level, passing to 1.26, increasing compared to the previous week and exceeding the threshold of 1. The average Rt calculated on symptomatic cases refers to the period 30 June-13 July and – we read in the Report – an increase in the transmissibility index based on cases with hospitalization is observed in a similar way (Rt 1.16 at 13/7/2021 compared to 0.97 the previous week).
“The high proportion of young and asymptomatic subjects highlighted by the epidemiological data published by the Istituto Superiore di Sanità – highlights the Report – must be considered when reading these transmissibility estimates”.
Strong increase in the incidence of Covid-19 cases in Italy which this week reaches 41 cases per 100 thousand inhabitants (according to data updated yesterday by the Ministry of Health) against the 19 cases of the previous week.
The data from the weekly monitoring of the Istituto Superiore di Sanità, referring to the period 12-18 July, reports an incidence of 31 cases per 100,000 inhabitants compared to 14 the previous week, but the Institute speaks equally of an “acceleration of ‘incidence “, specifying that” it is still below the value of 50 per 100,000 inhabitants every 7 days throughout the territory “. And adding that “the vaccination campaign continues and the incidence is currently at a level that could allow the containment of new cases”.
REGIONS AT MODERATE RISK
There are 19 Regions and Autonomous Provinces classified at moderate risk and two (Basilicata and Valle D’Aosta) are at low risk.
The circulation of the Delta variant is increasing in Italy and is now prevalent. This variant is leading to an increase in cases in other countries with high vaccination coverage, therefore it is advisable to carry out extensive tracking and sequencing of cases.
VACCINES, “HIGH COVERAGE NEEDED”
“It is necessary to achieve a high vaccination coverage and the completion of vaccination cycles to prevent further recurrences of episodes of increased circulation of the virus supported by emerging variants with greater transmissibility”. This is the recommendation contained in the draft weekly monitoring. “On the basis of ECDC data and forecasts, of the presence of outbreaks caused by the Delta viral variant in Italy and of the current vaccination coverage – it continues – it is advisable to maintain a high level of attention, as well as to apply and comply with the measures necessary to avoid a increased viral circulation “.
INTENSIVE CARE AND ADMISSIONS
No Region and Autonomous Province exceeds the critical occupancy threshold for beds in the intensive care or medical area. The employment rate in intensive care is stable at 2%, with a slight increase in the number of people hospitalized from 157 (as of 13 July) to 165 (20 July). The employment rate in medical areas nationwide remains at 2%. The number of people hospitalized in these areas is slightly increasing from 1,128 (13 July) to 1,194 (20 July).
“STRONG INCREASE IN CASES NOT ASSOCIATED WITH TRANSMISSION CHAINS”
There is a sharp increase in the number of new cases not associated with transmission chains (4,997 vs 2,408 the previous week). The percentage of cases detected through contact tracing activity drops further (30% vs 31% last week). The percentage of cases detected through the appearance of symptoms also decreased (44% vs 46%). Finally, 26% were diagnosed through screening activities, according to what emerges from the weekly monitoring.
