When analyzing samples from 959 people, all asymptomatic, who had participated in lung cancer screenings between September 2019 and March 2020, 11.6% (111 of 959) had antibodies against the coronavirus.
“There are no reliable data on the actual onset of the infection and on the spread in the pre-pandemic period throughout the world – reads the study -. We studied the presence of specific antibodies” linked to the onset of the coronavirus “in blood samples from 959 people asymptomatic patients enrolled in a prospective lung cancer screening study between September 2019 and March 2020 to control the date of appearance, frequency, and temporal and geographical variations in Italian regions. Antibodies specific to Sars-Cov-2 were detected EBR in 111 individuals out of 959 (11.6%), as of September 2019 (14%), with a cluster of positive cases (> 30%) in the second week of February 2020 and a higher number (53.2% ) in Lombardy “.
Of these 111 positives, 23 date back to September, October 27, November 26, December 11, January 3, and February 21. Those who tested positive come from 13 regions, half from Lombardy, followed by Piedmont, Lazio, Emilia-Romagna, Tuscany and Veneto.
“This study, to read again in the publication that has Giovanni Apolone as the first signatory, shows an unexpected very early circulation of Sars-Cov-2 among asymptomatic individuals in Italy several months before the identification of the first patient and clarifies the onset and the spread of the 2019 coronavirus disease pandemic (Covid-19). Searching for Sars-CoV-2 antibodies in asymptomatic people prior to the Covid-19 epidemic in Italy could reshape the history of the pandemic. “
Galli: “In Italy since September 2019? It’s hard to be so old” Massimo Galli, director of infectious diseases at the Sacco hospital in Milan, expresses strong doubts that the virus was in Italy already in September 2019. “Let’s see that we have real confirmations – he said -. It is really difficult to think that the virus is like this. If it was, you have to wonder why it didn’t spawn much earlier. One wonders about this virus in terms of such strong anticipation. In Milan it is said more slowly, more slowly “.
