The Omicron variant is highly transmissible. A study of SARS-CoV-2 lineages in South Africa found that the effective reproduction number of Omicron there was 3.31-fold higher than that of the Delta variant, which, in turn, was already 60% more transmissible than the Alpha variant. Omicron became the dominant variant worldwide almost immediately; within a mere 3 weeks, Omicron had been identified in 87 countries.

A study in New Zealand found that vaccinated individuals are almost as likely as unvaccinated ones to spread the Omicron variant. However, there is no evidence to suggest that the virus can be spread through the handling of food.
