Italy: In the fourth quarter of last year, the new coronavirus was in the incubation period

A recent study published by the National Cancer Institute in Milan, Italy, showed that new coronavirus antibodies were detected in blood samples taken by some residents in September last year, the Italian Evening Post reported Friday. This means that the new coronavirus spread in Italy as early as February this year.
17th, Montomori, a professor of public health at siena University and one of the lead authors of the study paper at the National Cancer Institute in Milan, gave an exclusive interview to reporters to explain why the new coronavirus did not have a large-scale outbreak in Italy in the fourth quarter of 2019.
Montomori, Professor of Public Health, University of Siena, Italy: If a virus develops into a pandemic requires an incubation period, we generally describe the development of the epidemic as a "bell curve", with lows and highs, so last October, November and December may be the low point of the outbreak curve, the outbreak curve began to rise in January, continued to rise in February and there was a small spike in the outbreak in Lombardo and other places.
the world, the traceability of the new coronavirus is advancing. A study published in June by Italy's Institute of Advanced Health showed that the new coronavirus may have been present in northern Italy in December, with experts detecting nucleic acids in wastewater sampled in Milan and Turin in December and bologna at the end of January.
addition, the University of Barcelona in Spain announced in June that a team led by the university had detected the new coronavirus in a sample of Barcelona wastewater collected in March last year. A study published in July by the Federal University of Santa Catarina in Brazil found that a team led by the university detected the new coronavirus in wastewater samples collected on November 27 last year in Florianopolis, the capital of santa Catarina state.Professor Montomory said that china's measures to review the outbreak of neo-crown pneumonia were impeccable, and that the virus traceability process was extremely complex and required the joint efforts of scientists from all fields around the world to conduct a wider range of analytical research, and he was willing to work with Chinese researchers.
Montomori , professor of public health at siena University in Italy , said : At that time , people knew almost nothing about the new coronavirus , but the strain was quickly isolated , And Wuhan took strict restrictions to contain the spread of the epidemic to the maximum extent possible . We are more than happy to work with our Chinese colleagues in the scientific community, and the virus can infect everyone everywhere, so to contain the epidemic and contain new infectious diseases, we must work together internationally.
