Bologna, 22 October 2021 – I am growing In Italy i contagion gives Covid 19. “On theincrease in infections in Italy you have to understand if it is due tothe high number of tampons, since we have gone from 300 thousand on average to over half a million per day. I spoke yesterday with Minister Speranza, in a few days we will know “, said the prime minister Mario Draghi, at a press conference in Brussels at the end of the European Council.
And in Emilia Romagna today the new cases of Coronavirus they come back to exceed 300 (315 new positives), recording a slight growth compared to yesterday when they were 294.
Two dead in the region related to pandemic, have passed away a 52-year-old man in the province of Piacenza e an 84-year-old woman in the province of Modena.

Coronavirus in Italy: data from 22 October
It was yesterday 3,794 new cases of positivity coronavirus recorded in the last 24 hours in Italy compared to 574,671 swabs carried out, for an incidence rate of 0.7%. 36 people died, for a total of 131,724 victims since the beginning of the pandemic. The number of beds occupied in intensive care increased by one unit (356), while ordinary hospitalizations fell by 25. This afternoon the Ministry of Health will disseminate the updated report and we will report it in this article.
The national RT is at 0.86 “below the epidemic threshold and slightly higher than the previous week” (0.85). This is what emerges from the note of the Higher Institute of Health (Iss) with the main data of the latest monitoring of the Queen’s Cabin. “It slightly increases the transmissibility index based on cases with hospitalization”, specifies the ISS.
The percentage of cases detected through is slightly increasing, the report notes the appearance of symptoms (48% vs 47%). The percentage of cases diagnosed through activities remains stable screening (19% vs 19%).
The weekly incidence is slightly up nationally: 34 per 100,000 inhabitants (15/10 / 2021-21 / 10/2021) vs 29 per 100,000 inhabitants (08/14 / 2021-07 / 10/2021), data from the Ministry of Health. The incidence is below the weekly threshold of 50 cases per 100,000 inhabitants which could allow the control of transmission based on containment or on the identification of cases and the tracing of their contacts.
Covid Bologna today: the infections
Among the 62 new cases of positivity in the province of Bologna, 50 swabs for the presence of symptoms, 4 were identified through contact-tracing activities, 1 case through serological screening, 1 case through tests by professional category, 2 cases through pre-tests hospitalization, while epidemiological investigations are still ongoing for 4 cases. Among the 62 new infections, 33 are sporadic and 29 are inserted in outbreaks. No cases were imported from other regions, nor from abroad.
How long the antibodies last
Those who have fallen ill with Covid have protection against the risk of becoming infected again it can last up to almost 2 years, unless you take precautions like getting vaccinated and wearing a face mask. This is indicated by the bioinformatic models, based on the genetic relationship between the SarsCov2 virus and other coronaviruses, published by Yale University in the journal Nature.
To estimate the duration of immunity from Covid, researchers led by Jeffrey Townsend wanted to understand how antibody levels from a previous infection affect the risk of re-infection. Data from a previous study allowed him to track this effect over the years on ‘endemic cold’ endemic coronaviruses, as SarsCov2 is too new to have long-lasting data.
To fill this gap, they combined the genetic data of SarsCov2, with those of three endemic coronaviruses and others linked to the SARS-CoV and MERS-CoV family, to build a viral family tree and model its evolution over time. The results obtained suggest that the average risk of re-infection increases by approximately 5% four months after the initial infection, up to 50% 17 months later. Overall natural protection appears to last less than half that of the three cold coronaviruses.
