Discussion: The omicron variant and holiday travel
Security forces stand guard inside an airport terminal in Rabat, Morocco, as the country announced it would suspend all incoming air travel for two weeks because of the rapid spread of the new omicron variant, Nov. 29, 2021.
Many people around the world are debating whether or not to travel this holiday season. The new omicron variant of COVID-19 has contributed to surges in places like South Africa, and scientists have been scrambling to study its effects and transmissibility. New clues are coming out each day, but definitive answers will take more time.
The variant was first reported in Southern Africa — setting off a series of travel bans from the region — but medical experts say it’s not clear where the variant originated. Cases were later identified in other parts of the world, which turned out to be present prior to the bans.
The UK and Denmark saw a spike in omicron cases over the weekend, and the variant has appeared in at least 57 nations worldwide.

South Africa is seeing a fourth wave in cases, and President Cyril Ramaphosa has said that the country is preparing its hospitals for more admissions.
