How is Vibrio Cholerae primarily transmitted?

• A. Through ingestion of contaminated food or water
• B. Through inhalation of aerosols
• C. Through blood transfusions
• D. Through person-to-person contact

Answer: (A)

Vibrio cholerae is spread mainly through the ingestion of water or food contaminated with feces from an infected person. This fecal-oral transmission means that when sewage contaminated with the bacteria enters drinking water, or when contaminated foods (often in areas with poor sanitation) are consumed, the bacteria reach the small intestine and produce toxins that cause the characteristic profuse watery diarrhea and dehydration. The infectious dose can be low, so even small amounts of contaminated material can cause illness, which is why outbreaks occur in places with unsafe water and sanitation. Inhalation of aerosols isn’t a typical route for cholera. Blood transfusions aren’t involved in its spread, since it’s a gut pathogen, not a bloodborne one. Direct person-to-person contact isn’t the usual mode of transmission, because the bacteria are shed in feces and transmitted via contaminated water or food rather than through close contact alone.
