Coronavirus, antibodies in over 1.4 million Italians: 6 times more than the recorded cases

The first results of the serological survey conducted on 64,600 people by the Ministry of Health and Istat. The hardest hit by Covid Healthcare workers and restaurateurs.

Sabbadini: “The data says that the infected are a small part. But that one cannot absolutely lower one’s guard, individual responsibility counts a lot.

More than one million and 400 thousand Italians have developed antibodies to SarsCov2. Which means that people who came into contact with the virus are six times more than the total number of officially registered cases during the pandemic.

The serological survey carried out on 64,660 individuals revealed a million and 482 thousand people with positive IgG, 2.5% of the population residing in the family.

In illustrating the data. Istat and the Ministry of Health have specified that the emergency conditions in which the survey took place. Did not allow to reach the 150 thousand subjects expected. However, the techniques adopted have allowed the production of estimates consistent with both the contagion and mortality data. The results of surveys conducted at local level.

All the plots and maps of the epidemic.

The territorial differences are very “accentuated” and Lombardy reaches the maximum with 7.5% of Seroprevalence. That is seven times the value found in the regions with the lowest diffusion, especially in the South.

“notes the report. 27.3% of people” who developed covid-19 antibodies did not experience any symptoms.

“The data tells us that the infected people are a small part, but also that you cannot absolutely. Which have been strongly followed by the population “.

Interesting data on antibodies.

The prevalence of the development of antibodies to SarsCov2 is similar for all age groups. The lowest level at 1.3% is for young children and the elderly is 1.8% and “This perhaps because there is” a protective effect of family members for these segments “. Healthcare workers affected by 9.8% and catering workers exceed 4%. There are no gender differences, added director Istat Linda Sabbadini.

“The 2.5% seroprevalence figure may seem small. It can turn into something problematic if we do not respect prudence”, clarified. Gian Carlo Blangiardo, president of Istat. “It seems little, but it is the territorial variation that is the important element. This means that the probability of meeting a positive person is 2.5: if I meet 20 people. I have a 50% chance of meeting a positive person” , concluded Blangiardo.

The Minister of Health Speranza announced the continuation of the government’s rigor.

“The study on seroprevalence is one of the decisive building blocks for studying coronavirus and finding adequate answers. The data tell us that the impact has been important. Also considering the international difficulties, the Government will continue with the line of caution and rigor”
