WASHINGTON: The discovery of a new coronavirus variant triggered global alarm on Friday as countries rushed to suspend travel from southern Africa and stock markets on both sides of the Atlantic suffered their biggest falls in more than a year.
But it could take weeks for scientists to fully understand the variant's mutations. Health authorities are seeking to determine if omicron is more transmissible or infectious than other variants and if vaccines are effective against it. Those worries pummelled financial markets, especially stocks of airlines and others in the travel sector, and oil, which tumbled by about US$10 a barrel.
The variant has a spike protein that is dramatically different to the one in the original coronavirus that vaccines are based on, the UK Health Security Agency said, raising fears about how current vaccines will fare.
