A recent study by the University of Barcelona found that Covid 19 traces were found in wastewater samples as early as March 2019.
Tom Jefferson, a volunteer senior research fellow from the Center for Evidence Based Medicine at Oxford University, has speculated that the coronavirus may be at a “dormant” stage.
He told the Daily Telegraph: “We may see a dormant virus that has been activated by environmental conditions.”
Professor Jefferson referred to one case that was discovered in the Falkland Islands in early February of this year, and another in which a cruise ship full of people who had originally been tested for the virus experienced an outbreak in the middle of the trip.
He said, “The explanation could only be that these agents are not coming or going anywhere. They̵
Melita Vujnovic, the representative of the World Health Organization in Russia, told the RIA Novosti news agency that she “could not rule out” the theory of COVID-19 that existed before the pandemic broke out.
“The WHO has built a large team that will work with Chinese scientists to analyze the origin of the virus.
“This virus lived in animals and was eventually transmitted to humans. It is difficult to say when and where this happened. It is being examined. Viruses can be found in wastewater. But nothing can be said specifically. “
James Wood, director of veterinary medicine at the University of Cambridge, said the idea that the virus was inactive was “weak”.
Instead, he claimed that COVID-19 was present in animals in front of humans, but it took some time for it to spread.

The study said: “This remarkable finding indicates the spread of the virus in Barcelona long before a COVID-19 case was reported worldwide.
“Barcelona is a business and commercial center as well as a popular venue for large events that visitors from many parts of the world attend.
“However, similar situations are likely to have occurred in several other parts of the world and unnoticed COVID-19 cases have spread to the community.”
However, some observers have expressed doubts as to whether what they discovered was really a corona virus.
A user of the medical journal MedRxiv doubted that the genes of the detected virus – called “E” and “N” in the study – really matched those of COVID-19.
They wrote: “The authors do not recognize SARS-CoV-2 in samples from March 2019. Rather, they recognize IP2 / IP4, which is similar to SARS-CoV-2. Whatever the virus is, it does not have the E and N1 / N2 of SARS-CoV-2. “
Other observers claim that the test samples may have been accidentally contaminated with existing COVID-19 traces during laboratory handling.
