In Italy, the coronavirus has been spreading since September 2019. This is reported in a study for the scientific journal Tumori Journal, prepared by scientists from Milan, Siena and Parma.
Among 959 asymptomatic patients who were screened for lung cancer from September 2019 to March 2020, 111 (11.6%) were found to have antibodies to coronavirus, scientists say.
In four, antibodies were detected in the first week of October 2019, which means they became infected in September, one of the authors of the study, Giovanni Apolone, explained to Reuters.
This means that the new coronavirus can circulate among the population for a long time and with a low mortality rate, not because it disappears, but only in order to then trigger a new outbreak.
In Italy, the authorities officially discovered the first two cases of the virus at the end of January in Chinese tourists. The first case of domestic transmission was detected here on 21 February. At the same time, researchers in March told Reuters that they recorded an increased number of cases of acute pneumonia and influenza in the Lombardy region in the last quarter of last year.
Italy ranks tenth in the world in the number of cases of coronavirus infection, follows from data from Johns Hopkins University. More than 1.17 million cases and 45,229 deaths have been identified in the country.
