Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Hepatitis D
Concept:

Certain human pathogens blur the lines between standard viruses and naked viroids.

Solution:

  • Hepatitis D is uniquely caused by a "viroid-like" pathogen known as the Hepatitis Delta Virus (HDV).
  • It possesses a tiny circular RNA genome and lacks its own envelope proteins, strictly requiring a co-infection with Hepatitis B to replicate and spread.


Why other options are incorrect:

  • Mad Cow / Mysterious brain infection: These are caused by prions.
  • Hepatitis A: Caused by a standard picornavirus.
