Concept
Transmission routes
How pathogens move between hosts
High-yield clue
Match the pathogen to its route: droplet vs airborne vs fecal-oral vs vector-borne vs bloodborne vs vertical.
Overview
The pathways by which infectious agents spread, including contact, droplet, airborne, fecal-oral, vector-borne, bloodborne, and vertical transmission. Recognizing the route explains prevention and epidemiology.
Classification
- Public-health concept
- Direct and indirect routes
- Horizontal vs vertical spread
Lab & identification clues
- Droplet spreads over short range; airborne stays suspended (vocabulary)
- Fecal-oral links to contaminated food/water
- Vertical transmission passes from parent to offspring
Associations
- Route determines precaution/barrier vocabulary
- Vector-borne overlaps with reservoir concepts
- Bloodborne pathogens spread by percutaneous exposure
Commonly confused with
- Droplet vs airborne
- Direct vs indirect contact
