Tracking the new coronavirus strains

New variants of the coronavirus have now been reported in at least 31 countries worldwide. One of these new strains named VUI-202012/01 was first reported in the United Kingdom on December 14 and is said to be up to 70 percent more transmissible than the previously dominant strain in the UK.

This means it is spreading faster in the UK, making the pandemic there even harder to control and increasing the risk it will also spread swiftly in other countries.

So far, there is no indication to believe the new mutation is any deadlier, or more likely to be able to evade vaccines or treatments.

The map and list below shows which countries have so far reported cases of the new strains of coronavirus.

Al Jazeera will update this list as more information becomes available (Updated December 31).
