Analysis of blood samples on nearly a thousand patients who had participated in lung cancer screening revealed the presence of specific antibodies five months before the discovery of the first patient with Covid-19

The SarsCov2 virus was circulating in Italy as early as September 2019, well before what has been hypothesized so far. The confirmation comes from a study by the Cancer Institute of Milan and the University of Siena, which has as its first signatory the scientific director Giovanni Apolone, published in the "Tumori Journal".
Analyzing the samples of 959 people, all asymptomatic, who had participated in lung cancer screenings between September 2019 and March 2020, 11.6% of these people had antibodies to the coronavirus, of which 14% as early as September , 30% in the second week of February 2020, and the largest number (53.2%) in Lombardy.
The study was possible precisely because the researchers decided to go and find the possible presence of specific antibodies in the blood samples taken from 959 people and thus trace the appearance, frequency and temporal and geographical variations of SarsCov2 infection in various Italian regions.
The results, i.e. the presence of these antibodies in 111 patients, show that the SarsCov2 virus began to circulate in Italy asymptomatically several months before the first Covid-19 patient was identified in February in Codogno - Mattia, the famous patient 1 for whom it seemed impossible to reconstruct the chain of contagion - and clarifies the emergence and spread of the pandemic virus, 'rewriting' the history of the epidemic.
