GENEVA, Aug 18 —Circulation of the Delta variant in areas of low vaccination is driving transmission of Covid-19 around the world, World Health Organisation officials said today.

"Many of the places around the world where Delta is surging—even in countries that at a national level have high levels of vaccination coverage—the virus, the Delta variant itself, is really circulating in areas of low level of vaccine coverage and in the context of very limited and inconsistent use of public health and social measures,” WHO epidemiologist Maria Van Kerkhove told an online news briefing.

Vaccines are clearly preventing increases in severe illness and death from the Delta variant, WHO Chief Scientist Soumya Swaminathan added. — Reuters
