"In addition to its rapid spread, there is now also some evidence that the new strain may be associated with high mortality," Johnson said.
The British Prime Minister clarified that the death rate from the new strain of coronavirus, compared to the "old" strain of Covid-19, is 30% higher. It notes that the evidence comes from mathematicians who analyze trends in the number of people dying from "new" and "old" strains.
At the same time, the chief scientific adviser to the government, Patrick Vallance, said the fatality data was "worrying" but "not yet convincing."
A new strain of coronavirus was discovered in Britain in December last year. Then the prime minister of the country said that the new strain of coronavirus is 70% more infectious than the usual one. The new strain has been reported in a number of countries, including Germany and Switzerland, France, Portugal, the Netherlands, Denmark, Norway and South Korea, Japan, Singapore, Australia and Canada.
The Director General of the World Health Organization Tedros Ghebreyesus said that the world has not overcome all the problems associated with the coronavirus pandemic. Future challenges include new strains of coronavirus.
