For decades, measles has taken the title of the most contagious virus among humans. That change was announced in late December, before the height of the omicron peak in the U.S. If a given population is broadly immune to other variants, he theorized, then Omicron will spread quickly even if it does not have an inherently superior transmission ability, because peoples immune systems will suppress competing variants.
