The omicron variant was already present in nearby countries, including our neighbouring Portugal, and therefore it cannot be ruled out that it could also be circulating in Spain.
In any case, up to now there is no clear consolidated certainty about its degree of transmissibility or severity, and there is some contradictory information.
The best measure to stop this variant, and any others that may arise later on, is to continue to make progress in global vaccination, because this is a NAPdemic.
Cancellation of travel, given that the variant is already circulating in countries where the same restrictions have not been put in place, can only serve to perhaps halt its rate of introduction to some extent, but not so much to prevent it.
