China News Service, November 16th. According to Euronet, the report of the Ministry of Emergency Civil Defense of Italy on the 15th showed that as of 18:00 on the 15th local time, the cumulative number of confirmed cases in Italy increased to 1,178,529, including 45,229 deaths. .
A study by the National Cancer Institute of Milan, Italy shows that the new coronavirus has spread in Italy since September 2019.
Data map: On October 24, local time, Rome, Italy, the Colosseum was empty after the curfew.
According to reports, on the 15th local time, the National Tumor Research Institute of Milan, Italy, informed the media that an official research report on the new crown virus signed by the director of the institute, Apolone, "The new crown virus was accidentally detected before the Italian new crown pneumonia pandemic Antibody, was officially published in the medical academic journal "Journal of Oncology" on November 11.
The research report shows that in the blood samples of Italian residents collected in early October 2019, antibodies to the new coronavirus have been successfully discovered and isolated. The researchers presume on this that the new coronavirus has begun to spread in Italy in September 2019.
The results of the study mean that the spread of the new coronavirus in Italy can be traced back to the summer of 2019, which is a full 5 months earlier than when researchers found that there were cases of new coronavirus transmission in the country in February 2020.
Earlier, in a lung cancer detection research project jointly cooperated by researchers from the National Cancer Institute of Milan, the University of Milan and the University of Siena, a total of 959 healthy people were recruited from September 2019 to March 2020. Volunteers and collected blood samples.
After the outbreak of the new crown virus, the researchers carried out the new crown virus detection and virus strain isolation studies on all 959 blood samples stored.
The results of the study showed that a total of 111 blood samples were positive for the new coronavirus, of which 16 were positive for immunoglobulin G antibodies and 97 were positive for immunoglobulin M antibodies.
Of the 111 positive blood samples, 6 were positive for the new coronavirus neutralizing antibody, 4 of which were collected in early October 2019.
The study author also mentioned that in November 2019, many doctors in Italy have found severe respiratory diseases in the elderly and vulnerable people. Since no information about the new coronavirus was found at that time, the medical department classified such diseases as Seasonal flu.
On February 20, 2020, Italy discovered the first case of indigenous new coronavirus infection.
Researchers believe that looking for virus antibodies from asymptomatic people before the outbreak of the new crown epidemic in Italy will reshape the history of the new crown epidemic.
In response to the presumption by the Italian national authoritative research institution that the Italian new crown virus has begun to spread in September 2019, Gali, the director of the infectious disease department of Milan Sacco Hospital and a famous infectious disease expert, said that he can hardly imagine the new crown virus in September 2019. It has already begun to spread.
If the facts are as stated in the research report, then why the virus did not have a large-scale outbreak at an earlier time will once again become another new research topic in the medical community.
