World Health Organisation’s chief scientist Soumya Swaminathan has said there was clear evidence that the coronavirus pandemic isn’t slowing down as the spread of Delta variant and slow pace of vaccination is leading to a surge in Covid-19 cases across most regions of the world.

She listed four major reasons for the continuous spread of the virus -- the Delta variant, social mixing, ease in lockdown restrictions and slow pace of vaccination.

Swaminathan said the fast-spreading Delta variant is certainly the most transmissible, most dangerous variant of Covid-19 seen so far and is the main reason behind the surge in infections. She said if one person infected by the original virus could infect close to three people, a person infected with the Delta variant could infect close to 8 people.
