Question

1. what factor significantly contributes to the spread of respiratory diseases in urban areas?

a. limited access to healthcare
b. zoonotic transmission
c. high population density
d. vector distribution

Explanation:

To determine the factor contributing to respiratory disease spread in urban areas:

• Option a (Limited access to healthcare) affects treatment, not direct spread.
• Option b (Zoonotic transmission) involves animal - human spread, less urban - specific.
• Option c (High population density) means closer contact, increasing respiratory disease spread (e.g., airborne pathogens).
• Option d (Vector distribution) relates to vector - borne diseases, not respiratory.

Answer:

c. High population density
