Omicron spreads to 57 countries but too early to tell if variant more infectious, WHO says

World Health Organization says new Covid variant spreading rapidly in South Africa, with cases doubling in the past week

The Omicron variant of Covid-19 has now been reported in 57 countries and continues to spread rapidly in South Africa, the World Health Organization (WHO) says.

But the latest epidemiological report from WHO says given the Delta variant remains dominant, particularly in Europe and the US, it is still too early to draw any conclusions about the global impact of Omicron.
