Italy was the first European country to be hit hard by the new corona virus, where its first case was thought to have occurred in February.
But now a study by an Italian expert has revealed that the corona virus had reached at least two major cities in December.
In fact, the study suggests that the virus first appeared in Italy when it was first reported in China.
The discovery was made in a study by the Italian National Institutes of Health after analyzing sewage water.
Researchers found traces of the virus in sewage water from Milan and Turin in December last year, while samples from the virus were found in sewers in Bologna in January.
Earlier, it was thought that the first case had been reported in Italy in mid-February, but researchers said the new findings would help determine the origin of the virus.
He also confirmed international evidence that sewage samples could be used to catch the virus early.
Earlier, it was said that the virus had started spreading from a wildlife market in Wuhan in December, but now Chinese officials have recently said that the virus may have started spreading from somewhere else.
Some research reports then claim that the virus existed in China before December.
The first case of a Chinese tourist in the Lombardy region was reported in mid-February in Italy.
A severe lockdown was imposed across Italy in early March, and the virus has killed 34,500 people so far.
In this study, experts reviewed 40 samples of sewage water from October 2019 to February 2020.
The results were confirmed by 2 different methods in 2 different laboratories that the virus was present in Milan and Torres on 18 December 2019.
The virus was not detected in the October and November samples.
The findings reinforce the evidence that people in France were affected by the end of December.
Similarly, in Spain, it was recently discovered that corona virus was present in sewage water in Barcelona in mid-January, although the first official case was discovered 40 days later.
Adriano Deserley, a professor of epidemiology at the University of Milan, said in March that Lombardy and Milan hospitals had seen a significant increase in pneumonia and flu cases between October and December last year, according to Reuters.
He said he could not give exact figures yet, but during the last quarter of 2019, there were more cases than usual in hospitals in which patients experienced symptoms such as pneumonia and the flu, and some died.
They are now reviewing hospital records and other details of cases, such as the number of deaths at home, to help determine if the virus had spread to Italy in late 2019.
“We want to know if the virus reached Italy at the end of 2019 and if so, why it has not been caught for so long,” he said.
The Italian professor says that once his investigation is complete, the local medical authorities may consider examining the bodies of those who died of suspected symptoms.
A study by the University of Cambridge in the UK in April suggested that the Novel Coronavirus outbreak may have started in mid-September last year and did not start in the Chinese city of Wuhan.
The Umbridge University study is working to find the root cause of the Code 19 epidemic, and the research team hopes to identify the first person to become the first victim of the virus, after which it can spread. Started
While analyzing the virus’s spread network, they have so far been able to chart its spread, including genetic mutations, to determine how the virus spread from China to Australia, Europe and the rest of the world.
The study looked at more than 1,000 complete genomes of the corona virus, which were sequenced in human patients.
The virus was later divided into type A, B and C based on genetic mutations, and the type A type A virus may have been transmitted from bats to pangolins in humans.
Type A was discovered among Chinese and American citizens, with modified versions reaching Australia and the United States.
According to the research, in most of the cases in Wuhan, type A virus was not seen but type B virus was active, which indicates that it started to change from an event there.
The Type C version came from the abdomen of the Type B, which was seen in early cases in Europe, while patients were also found in South Korea, Singapore and Hong Kong, but no signs of it were found in China.
According to the researchers, the data collected show that the Corona virus epidemic began to spread between September 13 and December 7 and is based on the rate of change in the virus.
However, the scientists said that the time estimate may be wrong, but at the moment this estimate seems to be correct, in this regard, more patient samples will be analyzed.
Peter Forster, head of the research team, said the outbreak may not have started in Wuhan because the type B virus was found in all patients there, but in Guangdong Province, 500 miles from Wuhan, out of 11
Type A was seen in 7 genomes, a very small number because the number of genomes in the early stages of the epidemic was very small.
Referring to the identification of the root cause of the virus, he said that it was necessary to prevent it from happening again in the future and to find out the factors that led to the spread of Code 19.
For the first time, scientists tracked the spread of the virus using technology used to migrate humans to find the origin of the virus.
The findings were published in the journal Proceedings of the National Academy of Sciences.
A report in March states that the first case of the virus was reported on November 17.
This was stated by China Morning Post with reference to the analysis of cases of corona virus by the Chinese government.
The first possible case was reported on November 17, according to Chinese government data.
Since then, one to five new cases have been reported daily, and by December 15, the number of code 19 patients had risen to 27, while on December 17, 10 cases were reported for the first time, and on December 20, the number of certified cases had reached 60.
On December 27, Dr. Zheng Jixian of the Hubei Provincial Hospital of Integrated told Chinese medical officials about the new corona virus, which had more than 180 patients, but doctors still told him There was not much awareness about.
On the last day of 2019, December 31, the number of certified cases reached 266 and on January 1, it reached 381.
According to the report, the Chinese government’s record was not released to the public, but it does provide important clues about the rate of spread of the disease in the early days and how many cases were reported in China by that time. ۔
Scientists are also looking to find the first source of the new corona virus, which is thought to have spread from an animal-like bat to another animal and then to humans. Moved.
According to government data, it is possible that such cases were reported even before November and are being investigated
