WebLee: Variants develop when a virus is transmitted. Every time it reproduces in a new host, a virus has an opportunity to mutate, to reproduce incorrectly. Most of the mutations are harmless, but sometimes the change will result in a stronger or more contagious version of a virus. And when that happens, it hurts us.
