Michael Ryan, director of the World Health Organization (WHO) emergency program, praised the coronavirus in Italy in December 2019. It is reported by RIA Novosti.
According to him, the identification by Italian scientists of COVID-19 in wastewater at this stage does not change the situation with the origin of the virus.
At the same time, Ryan called the study interesting and noted that it must be continued. He also added that it is not currently known what effect the presence of COVID-19 in the environment had on the outbreak of coronavirus infection in Italy and whether imported cases could have triggered it.
Earlier, the Italian National Institute of Health (ISS) said that traces of coronavirus infection were found in samples taken from the wastewater of Italian Milan and Turin. Experts explained that the results indicate that the coronavirus could penetrate the country back in December 2019.
In May, French scientists announced the possible timing of the appearance of coronavirus in Europe: a new infection could have entered there in November – two months before the first infection was officially confirmed in the country. In addition, 12 cases of coronavirus were detected in December and early January.
