Global rise in Covid-19 cases is 'tip of the iceberg' - WHO

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.

After more than a month of decline, Covid cases started to increase around the world last week, the WHO said, with lockdowns in Asia and China's Jilin province battling to contain an outbreak.
