Nations try to balance Omicron restrictions while keeping economies open

Global Covid-19 infections hit a record high over the past seven-day period, Reuters data showed on Wednesday, as the Omicron variant raced out of control and governments tried to contain its spread without paralysing fragile economies.

Almost 900,000 cases were detected on average each day worldwide between Dec. 22 and 28. A number of countries posted all-time highs during the previous 24 hours, including Argentina, Australia, Bolivia, the United States and many nations in Europe.

Studies have suggested Omicron is less deadly than some previous variants. But the sheer number of people testing positive could overwhelm hospitals in some countries and leave e-businesses struggling to carry on without workers who government officials have ordered to quarantine.
