👉 The Devil Flu, also known as the "Flu of the Damned," is a fictional disease often depicted in horror and supernatural literature, characterized by its relentless and almost supernatural spread. Unlike typical viral infections, it seems to defy conventional medical treatments and can cause extreme psychological and physical degradation in its victims. Symptoms include intense, uncontrollable rage, hallucinations, rapid heart rate, and a relentless thirst for human flesh. The fluid itself is not a physical substance but rather a metaphorical representation of the disease's corrupting influence, spreading fear and chaos, and ultimately leading to its victims' demise.
