According to a report on the 15th by the Italian “Evening Post”, a study recently published by the National Cancer Institute of Milan, Italy showed that the institute detected antibodies to the new coronavirus in some residents’ blood samples collected in September last year. This means that the spread of Coronavirus in Italy is much earlier than this February.
On the 17th, one of the main authors of the research paper at the National Cancer Institute of Milan, Monto Mori, a professor of public health at the University of Siena, accepted an exclusive interview with a reporter from the main station and explained why Coronavirus did not exist in the fourth quarter of 2019. The cause of the large-scale outbreak in Italy.
Monto Mori, professor of public health at the University of Siena, Italy: If a virus develops into a pandemic, it takes a period of incubation. We generally describe the development of the pandemic with a “bell curve”. There are lows and highs. Therefore, in October last year, November and December may be the low point of the pandemic curve. In January this year, the pandemic curve began to rise, and it continued to rise in February with small peaks in Lombardy and other places.
Around the world, the traceability of the new coronavirus is constantly advancing. A study published by the Italian Institute of Advanced Health in June showed that Coronavirus may have appeared in northern Italy in December last year. Experts sampled wastewater from Milan and Turin in December last year, and at the end of January this year. The new coronavirus nucleic acid was detected in the wastewater of the city of Bologna.
In addition, the University of Barcelona in Spain issued an announcement in June that a research team led by the school had detected the Coronavirus in Barcelona wastewater samples collected in March last year. A research report published by the Federal University of Santa Catarina in Brazil in July pointed out that a research team led by the university collected data from Florianópolis, the capital of Santa Catarina State, on November 27 last year. The new coronavirus was detected in wastewater samples.
Virus traceability requires the joint efforts of scientists from all countries
Professor Monto Mori said that looking back on Coronavirus pandemic, China’s measures are impeccable; and the virus traceability is extremely complicated and requires scientists from all over the world to work together on a larger scale of analysis and research. He is willing to research with China. People work together.
Monto Mori, professor of public health at the University of Siena, Italy: At that time, people knew almost nothing about Coronavirus, but the virus strain was quickly isolated. Wuhan also adopted strict restrictions to curb the spread of the pandemic with the greatest effort. China has made its best efforts, and I think no other country can achieve this level. We are very willing to cooperate with colleagues in the Chinese scientific community. Viruses can infect everyone everywhere. Therefore, to contain the pandemic and contain new infectious diseases, we must achieve international cooperation.
