COVID-19: Omicron cases surge by up to 400% in South Africa - but vaccine effectiveness 'encouraging'

Omicron coronavirus cases have surged by as much as 400% in some parts of South Africa - although the country's health ministry has said there is mounting evidence the variant causes milder infection.

South Africa reported more than 22,000 new infections on Thursday, a record during the fourth wave but still below the more than 26,000 daily cases seen during the peak of the Delta variant.
