WHO says new COVID-19 variants now in dozens of countries
GENEVA: New COVID-19 variants that make the virus more contagious and could render vaccine and antibody protection less effective have spread rapidly across dozens of countries, the World Health Organization said Wednesday.
In its latest epidemiological update, the UN health agency said the more contagious COVID-19 variant first spotted in Britain had by January 25 spread to 70 countries across all regions of the world.
