Question

1. which of these diseases is not typically spread through airborne transmission?

a. common cold
b. influenza (flu)
c. malaria
d. tuberculosis

1. the primary purpose of wearing a mask during a respiratory disease outbreak is to:

a. prevent vector - borne transmission
b. reduce indirect contact transmission
c. block airborne transmission
d. stop transmission through bodily fluids

Explanation:

For question 7:

• Common cold, influenza (flu), and tuberculosis are typically spread through airborne transmission.
• Malaria is transmitted by mosquitoes (vector - borne), not airborne.

For question 8:

• Masks are worn during respiratory disease outbreaks mainly to block airborne transmission (e.g., droplets in the air).
• Vector - borne transmission (A) is for diseases like malaria (mosquitoes), indirect contact (B) is about touching contaminated surfaces, and stopping transmission through bodily fluids (D) is not the main purpose of masks in respiratory outbreaks.

Answer:

1. C. Malaria
2. C. Block airborne transmission
