WHO: Delta variant to dominate within months
The highly contagious Delta variant of COVID-19 is expected to become the dominant strain of the virus over the coming months, the World Health Organisation said on Wednesday.
Delta, which was first detected in India, has now been recorded in 124 territories — 13 more than last week – and already accounts for more than three-quarters of sequenced specimens in many major countries, the WHO said.
Of the three other coronavirus variants of concern (VOCs), Alpha, first detected in Britain, has been reported in 180 territories (up six from last week), Beta, first detected in South Africa, in 130 (up seven) and Gamma, first detected in Brazil, in 78 (up three).
