Today we talk about rabies, one of the most terrifying, relentless, and near-100% fatal viral infections in human history.

Caused by the Rabies lyssavirus, this ancient pathogen operates almost like a biological horror story. Once introduced into muscle tissue through an infected bite or scratch, it avoids detection by bypassing the bloodstream entirely.
