Professor Tom Jefferson of the University of Oxford's Center for Evidence-Based Medicine said that Corona virus "Covid 19" may have been dormant in many regions of the world before it became active when environmental conditions became favorable to it. He pointed out that recent discoveries confirm the presence of the Corona virus in a number of countries in the world before its appearance in Wuhan last December, and from these countries there are samples of the virus in sewage in Spain, Italy, and Brazil in times before it appeared in China. According to the newspaper "Daily Mail".
"Weird things like this happened during the Spanish influenza pandemic. In 1918, 30% of the population of Western Samo, a country made up of two islands in the Atlantic, died from the Spanish flu," Professor Jefferson said during his discussion of the possibility of the virus not appearing in China. They have no contact in the outside world, "he added." And the explanation of this is that these viruses do not transmit anywhere but are always present, and perhaps they activate as a result of population density appropriate environmental conditions, and this is what we must look for. "
Viral pathologists in Spain said they found traces of the disease in sewage samples dating back to March 2019, about a year before the epidemic appeared in Europe. Italy's health officials said they found the virus in sewage in cities such as Milan and Turin in December. The researchers in Brazil said they found the effects of the virus in sewage samples taken from the city of Floriapolis last November.
But scientists are still confused about how the virus transmitted to humans, after it was linked to mice and pangolin and snakes. Some experts believe that the virus has been present in animals for decades before it adapts and becomes able to infect humans. "It is definitely not a new virus. Perhaps it was circulating among animals in China or in other regions of Asia, perhaps for several years, maybe decades," Sir Sir Jeremy Farrar, director of the British Wellcome charity for global health, told The Mail Online in January. It has had an effect on humans only now. "
