The new strain of corona virus (SARS-CoV-2) that caused the Covid-19 epidemic appeared in Italy starting in September 2019, suggesting that the epidemic may have spread outside of China earlier.
The information above was provided by the National Cancer Institute (INT) in Milan. INT offers evidence that the first Italian Covid-19 patient was discovered on September 21, 2019 in a small town near Milan, in the northern Lombardy region of the country.
According to the article published in the scientific journal Tumori Journal of INT, more than 11% of the samples (111 people) presented antibodies characteristic of the new coronavirus strain. All of them showed no symptoms.
This explains why some 23 positive cases of Covid-19 in Italy date back to September last year. The above conclusion is based on the analysis of blood samples from 959 people, collected at the time of lung cancer detection from September 2019 to March 2020.

The University of Siena, in the Tuscany region, is conducting a more specific study of antibodies against SARS-CoV-2 entitled “Unexpected detection of antibodies against SARS-CoV-2 in pre-pandemic Italy”.
Research has shown that four cases analyzed since the first week of October 2019 are also positive for antibodies that neutralize the SARS-CoV-2 virus. Giovanni Apolone, a co-author of the study, said that this means they have been ill since September 2019.
Earlier in March, researchers in Italy revealed to Reuter that they had recorded unusually severe cases of pneumonia and flu in the Lombardy region in the fourth quarter of 2019. It was an indication of the possibility of vaccination. The SARS-CoV-2 virus can spread sooner than we think.

According to the World Health Organization (WHO), the SARS-CoV-2 virus and the Covid-19 epidemic were not known before the first outbreak of outbreaks was recorded in the Chinese city of Wuhan in December 2019. However , WHO says “it is impossible to rule out the possibility that the virus has spread silently to other places.”
On November 16, the pharmaceutical company Moderna announced that its experimental vaccine was 94.5% effective in preventing Covid-19, based on temporary data from an advanced-stage trial, from becoming a manufacturer. The second largest US drug maker reported results that far exceeded expectations.
Along with the vaccine from pharmaceutical company Pfizer, which is also more than 90% effective and awaits additional safety data and regulatory review, the US may have two vaccines approved for emergency use in December. with around 60 million doses of vaccines available this year.
The information caused the commotion of the WHO but said that there were still many problems to be solved and that there was no time to be complacent. Only a very limited amount of vaccine will be available in the first half of 2021, WHO officials say.
Soumya Swaminathan, WHO chief scientist, said Moderna’s results were “encouraging” and that participants should be monitored for two months for side effects. Ms Soumya Swaminathan added that clinical trials should continue to collect more data and more vaccine trials will show more results in the coming weeks.
WHO Director-General Tedros Adhanom Ghebreyesus during a press conference: “Although we continue to receive encouraging news about the Covid-19 vaccine and remain cautiously optimistic. is extremely concerned about the increase in Covid-19 cases in European and American countries. “
