virulent

What does "virulent" mean?
The word "virulent" describes something extremely infectious, poisonous, or harmful in its effects. Imagine a fast-spreading, aggressive virus or a chemical substance that destroys whatever it touches; it carries the mental image of something potent, hostile, and rapidly destructive. In a non-biological context, it is frequently used to describe speech, criticism, or attitudes that are intensely bitter, malicious, or hateful. While you might hear it in medical reports regarding a "virulent strain" of bacteria, you are just as likely to see it in news analysis describing a "virulent attack" on someone’s character or a "virulent campaign" of misinformation.
