The World Health Organisation cautioned against major alarm over a new, highly infectious variant of the coronavirus that has emerged in Britain, saying this was a normal part of a pandemic’s evolution.
WHO officials even put a positive light on the discovery of the new strains that prompted a slew of alarmed countries to impose travel restrictions on Britain and South Africa, saying new tools to track the virus were working.
“We have to find a balance. It’s very important to have transparency, it’s very important to tell the public the way it is, but it’s also important to get across that this is a normal part of virus evolution,” WHO emergencies chief Mike Ryan told an online briefing. major
“Being able to track a virus this closely, this carefully, this scientifically in real time is a real positive development for global public health, and the countries doing this type of surveillance should be commended.”
Citing data from Britain, WHO officials said they had no evidence that the variant made people sicker or was more deadly than existing strains of COVID-19, although it did seem to spread more easily. major
Countries imposing travel curbs were acting out of an abundance of caution while they assess risks, Ryan said, adding: “That is prudent. But it is also important that everyone recognises that this happens, these variants occur.”
WHO officials said coronavirus mutations had so far been much slower than with influenza and that even the new UK variant remained much less transmissible than other diseases like mumps.
They said vaccines developed to combat COVID-19 should handle the new variants as well, although checks were under way to ensure this was the case.
