Almost twice as many people were diagnosed with Covid-19 in the past seven days as the pandemic’s previous weekly record thanks to a tsunami of omicron that has swamped every aspect of daily life in many parts of the globe.

The highly mutated and infectious variant drove cases to a record 10 million in the seven days through Sunday, almost double the previous record of 5.7 million seen during in a week in late April. The surging number of infections, at a time when many people have given up on testing or are using at-home kits with results that aren’t reported to local authorities, has led to canceled flights, closed offices and strangled production facilities and supply chains.
