The WHO has identified three new variants of coronavirus originating in the UK, Brazil and now in South Africa.
  • Of the three, the latest South African variant known as 20H/501Y.V2 or B.1.351 appears to be more infectious than the original virus.
  • This potentially more concerning variant, which has been spotted since December 22 last year and spread to nearly 40 countries including the United States.
