Cholera
Toxin-mediated profuse watery diarrhea
KOL-er-uh
High-yield clue
Painless, profuse rice-water stools with rapid dehydration is the classic cholera clue.
Overview
An acute secretory diarrheal disease caused by toxigenic Vibrio cholerae, studied for its massive watery output and rapid dehydration. It matters as the classic example of an enterotoxin driving fluid loss and as an epidemic, water-linked public-health threat.
Classification
- Secretory diarrheal syndrome
- Toxin-mediated (cholera toxin) mechanism
- Non-inflammatory watery pattern
- Epidemic water-linked framing
Lab & identification clues
- Rice-water stool description (flecks of mucus, no blood)
- Massive-volume, non-inflammatory diarrhea vocabulary
- Rapid dehydration and electrolyte-loss framing
- Oral rehydration as a public-health concept
Associations
- Fecal-oral spread via contaminated water and food
- Explosive outbreaks after disasters and poor sanitation
- At-risk framing: crowded, low-sanitation settings
- Cholera toxin as the enterotoxin driving fluid secretion
Commonly confused with
- Enterotoxigenic E. coli diarrhea
- Typhoid fever
