Does it spread more easily? Make people sicker? Mean that treatments and vaccines won’t work? Questions are multiplying as fast as new strains of the coronavirus, especially the one now moving through England. Scientists say there is reason for concern but that the new strains should not cause alarm.
“There’s zero evidence that there’s any increase in severity” of COVID-19 from the latest strain, the World Health Organization’s emergencies chief, Dr. Michael Ryan said Monday.
“We don’t want to overreact,” the U.S. government’s top infectious disease expert, Dr. Anthony Fauci, told CNN.
Worry has been growing since Saturday, when Britain’s prime minister said a new strain, or variant, of the coronavirus seemed to spread more easily than earlier ones and was moving rapidly through England. Dozens of countries barred flights from the U.K., and southern England was placed under strict lockdown measures.
