How is Histoplasmosis pneumonia acquired?

• A. By breathing in microscopic spores from soil, especially areas with bird or bat droppings.
• B. Through person-to-person airborne droplets.
• C. By eating undercooked poultry.
• D. Via skin contact with contaminated soil.

Answer: (A)

Histoplasmosis pneumonia is acquired when you inhale the microscopic spores of Histoplasma capsulatum that are present in soil enriched with bird or bat droppings. Disturbing such soil—like during construction, exploring caves, or cleaning roost areas—releases spores into the air and you breathe them into your lungs. Once inhaled, the spores can cause infection in the lungs and may lead to pneumonia-like symptoms in some people. This is not a person-to-person airborne disease, so transmission isn’t from one person to another. Similarly, eating undercooked poultry isn’t a route for this fungus, and skin contact with contaminated soil doesn’t cause infection because the problem starts with inhaled spores, not skin exposure.
