Cholera Pathogen and Transmission

Steps:

• Recall that cholera is caused by the bacterium Vibrio cholerae.
• Identify transmission as fecal-oral route through contaminated water or food.
• Eliminate viral options since cholera is bacterial.
• Confirm water contamination matches primary spread, not inhalation.

Why A is correct:

• Cholera is caused by bacteria (Vibrio cholerae) and spreads via drinking water contaminated with fecal matter containing the pathogen, per standard epidemiology definitions.

Why the others are wrong:

• B: Inhalation of water droplets is not a transmission method for cholera; it's waterborne, not airborne.
• C: Cholera is bacterial, not viral.
• D: Cholera is neither viral nor transmitted by inhaling droplets.

Final answer: A
