Global Covid-19 cases up 11% last week, Omicron risk high

The World Health Organization says the number of Covid-19 cases recorded worldwide increased by 11 per cent last week compared with the previous week, with the biggest increase in the Americas. The gain followed a gradual increase since October.

The UN health agency said in its weekly epidemiological report released late Tuesday that there were nearly 4.99 million newly reported cases around the world from December 20-26.

Europe accounted for more than half the total, with 2.84 million, though that amounted to only a 3 per cent increase over the previous week. It also had the highest infection rate of any region, with 304.6 new cases per 100,000 residents.

WHO said that new cases in the Americas were up 39 per cent to nearly 1.48 million, and the region had the second-highest infection rate with 144.4 new cases per 100,000 residents. The US alone saw more than 1.18 million cases, a 34 per cent increase.

Reported new cases in Africa were up 7 per cent to nearly 275,000.

The agency said that “the overall risk related to the new variant … omicron remains very high.” It cited “consistent evidence” that it has a growth advantage over the delta variant, which remains dominant in parts of the world.
