The Corona virus-Pandemic continues to expand. Covid-19 was first discovered in late December 2019 in the city of Wuhan in the Chinese province of Hubei. The researchers are still debating whether this was actually the first case worldwide. A team of scientists now even claims that this is dangerous virus has already spread “among people for years or even decades”.

Coronavirus news up to date: Covid 19 pathogens are said to have spread for years
As is currently the case with the British “Daily Star” To read, the researchers believe that a coronavirus strain had grown from an animal a decade ago man could have jumped. At that time, however, the virus strain was said not to have caused a disease in humans. The results of the research were published in the journal “Nature Medicine” after a team of experts had analyzed the pandemic around the world.
Researchers claim that coronavirus may have developed over decades
Dr. Francis Collins, director of the US National Institute of Health, described the virus “… as the result of gradual evolutionary changes that have spanned years or maybe decades. The virus eventually gained the ability to spread from human to human and serious , often causing life-threatening changes. ” The researcher added, “Since many early cases of Covid-19 have been linked to the Huanan market in Wuhan, it is possible that an animal source was present at this location.”
Did Covid-19 come to Europe in 2019? New investigations should bring clarity
They found that bats and pangolins had been infected with coronaviruses similar to those found in Covid 19 disease. So far, however, it has not been possible to conclusively clarify whether the virus has actually spread from animal to human. Meanwhile, Italian researchers are investigating whether the higher number of severe pneumonia and flu cases in Lombardy in the last quarter of 2019 could be a signal that the novel coronavirus may have spread beyond China earlier than previously thought.
Experts are examining old deadly flu cases for possible corona indications
Adriano Decarli, epidemiologist and professor of medical statistics at the University of Milan, said that the number of patients treated for pneumonia and flu in the areas of Milan and Lodi increased “significantly” between October and December last year. Even back then, the doctor said that patients with pneumonia and flu-like symptoms were hospitalized and died a little later.
Decarli is now planning to examine the hospital records of these cases, including those who later died at home, to find out if the coronavirus may be in much better shape Europe has spread than previously thought. “We want to know if the virus was here in Italy by the end of 2019 and if so, why it remained undetected for a relatively long time so that we have a clearer picture in case we have to face a second wave of the epidemic,” said Decarli.
Discussions about exact corona outbreak are ongoing
Other experts question the hypothesis that the novel virus had spread to Europe before the end of 2019. “I think it is extremely unlikely that the virus was spread to Europe before January,” said Paul Hunter, professor of medicine at the University of East Anglia in the UK.
