(VOVWORLD) - 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 restriction to try to seal themselves off.

The World Health Organization (WHO) 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. The WHO said understanding the level of severity of Omicron "will take days to several weeks".
The detection of Omicron triggered global alarm as governments around the world scrambled to impose new travel curbs.
Omicron, dubbed a "variant of concern" last week by the WHO that is potentially more contagious than previous variants, has now been detected in Australia, Belgium, Botswana, Britain, Denmark, Germany, Hong Kong, Israel, Italy, the Netherlands, France, Canada and South Africa.
