(CNN) — Countries around the world are imposing bans and restrictions on travel from the United Kingdom to stem the transmission of a coronavirus variant that health authorities say can spread faster than others.

The new variant discovered in the UK prompted authorities to impose a Tier 4 lockdown in London and southeast England and tighten restrictions for all of England over the festive period.

Since the UK lockdown was announced on Saturday, more than a dozen countries in Europe, Asia, South America and the Middle East have restricted travel from the UK and in some cases, also travel from other countries that have documented cases with the variant.

The variant has also been detected in Denmark, the Netherlands and Australia, according to the World Health Organization. In South Africa, a different coronavirus variant has been reported, the WHO’s technical lead for Covid-19, Maria van Kerkhove, said Monday.

The UK Foreign, Commonwealth and Development Office (FCDO) is working to support British nationals affected by the travel disruptions caused by the new restrictions, which have cut off UK travelers from much of Europe and other parts of the world.

The United States had not issued a ban on travel from the UK as of late Monday afternoon.

“CDC is following the situation closely and actively assessing the implications of the new variant and response options with respect to international travel,” according to a statement from the US Centers for Disease Control and Prevention.
