The Omicron coronavirus variant spread around the world on Sunday, with new cases found in the Netherlands, Denmark and Australia even as more countries imposed travel restrictions to try to seal themselves off. The World Health Organization said it was not yet clear whether Omicron, first detected in Southern Africa, is more transmissible than other variants, or if it causes more severe disease.
