When people use the term "bug" they mean a "germ," which is a general term used to describe microorganisms, with a "virus" being the primary one most people talk about, especially when they are discussing cold and flu.

They do not literally mean a "bug," like an ant or cockroach. They mean a "virual bug."

Influenza is universally considered to be a virus (Influenza A and Influenza B, as examples) by mainstream normie thinking.

If YOU did not intend to mean that, they YOU should be more clear in your communication.

And since you did not respond to anything I wrote, I am guessing that you are not reading my posts. You just stopped at "flu virus" and got triggered.
