Humanity has covered almost 60% of the way in the fight against coronavirus, but new strains of Covid-19 could significantly delay the end of the pandemic. This was stated by the leading researcher of the World Health Organization Sumiya Swaminathan in an interview with the Swiss Blick.
According to the WHO representative, it is "premature" to say that the pandemic will end soon.
"For this there is a lot of unknown... In particular, this is the unexpected appearance of new variants of the virus," she explained.
Swaminathan noted that in some parts of the world a very high percentage of the population is vaccinated - 70-80%, while in others, for example in all of Africa, less than 4% of the population is fully immunized.
"The longer we put up with this situation, the more likely new options will emerge," added a WHO spokesperson.
The executive director of the American research company Bioscience Resource Project, Dr. Jonathan Latham, believes that Covid-19 could have developed in the body of an infected Chinese miner almost ten years before the start of the pandemic.
He was prompted to such conclusions by a study by scientists from the University of Cambridge, who found that the highly infectious Alpha strain had developed in one immunocompromised patient who had been sick with coronavirus for many months.
