Question

select the correct answer.
many pigeons live near martyns air conditioning vents martyn isnt able to clean the vents properly, and they often contain dried pigeon droppings martyn eventually falls
sick with a respiratory illness. which mode of disease transmission most likely made martyn sick?
o a. oral
o b. aerosol
o c. vector
o d. fomite
o e. direct contact

Explanation:

Martyn’s respiratory illness likely stems from dried pigeon droppings in air vents. Dried droppings can release tiny airborne particles (aerosols) containing pathogens, which are inhaled into the respiratory system. This matches aerosol transmission, where disease spreads via airborne particles. Other options don’t fit: oral involves ingestion, vector uses carriers like insects, fomite is contaminated surfaces, and direct contact requires physical touch—none align with the vent/airborne path described.

Answer:

B. aerosol
