Micro 38 – Role of Viruses in Disease
This episode translates viral mechanisms into recognisable clinical syndromes. Drawing from Murray’s Chapter 38, it explores how viruses produce disease patterns across organ systems - respiratory, gastrointestinal, neurologic, hepatic, cutaneous, and systemic.
The narrative emphasises tropism: viruses infect specific tissues based on receptor availability and replication compatibility. Respiratory viruses target epithelial surfaces; neurotropic viruses invade peripheral nerves; hepatotropic viruses localise in the liver; lymphotropic viruses alter immune regulation.
