Meaning of "virulence" ("virulencia"), detailed definition, and a short video lesson below.

Virulence is a word scientists use to describe how dangerous a germ is and how quickly it can spread and make many people or animals sick. A germ with high virulence is like a super-speedy troublemaker, making lots of bodies feel bad very quickly.
