WHO: Delta variant of Covid-19 is the 'most transmissible', reported in 85 nations

The World Health Organisation has said that the Delta Variant of Covid-19, first detected in India, is the “most transmissible” variant identified so far and warned that it is now spreading in at least 85 countries.

At a press briefing on Friday, the WHO director-general said the vaccine inequality in poorer countries was exacerbating the delta variant's transmission. He said developing nations are disappointed because there are no vaccine to allocate, criticizing rich countries for declining to immediately share jabs with the rest of the world.

The WHO chief said the global community was failing and risked repeating the mistakes made during the AIDS crisis decades ago and during the 2009 swine flu pandemic, when vaccines only arrived in poor countries after the outbreak ended.
