WHO says global rise in Covid cases is ‘tip of the iceberg’

A combination of factors was causing the increases, including the highly transmissible Omicron variant and its BA.2 sublineage, and the lifting of public health and social measures, the WHO said.

Figures showing a global rise in Covid-19 cases could herald a much bigger problem as some countries also report a drop in testing rates, the WHO said on Tuesday, warning nations to remain vigilant against the virus.
