Variant transmission

Variant transmission refers to how different versions, or variants, of a virus spread from person to person. When a virus replicates, it can mutate, creating new variants with slight differences. Some variants may spread more easily or be more infectious than others. Transmission describes the process of these variants passing through populations via respiratory droplets, touch, or other means. Tracking how variants transmit helps health experts understand their spread, assess risks, and develop strategies like vaccines and public health measures to control outbreaks effectively.
