Tuberculosis, varicella, and rubeola are examples of infections transmitted via what method?

• A. Contact transmission
• B. Airborne transmission
• C. Vector-borne transmission
• D. Droplet transmission

Answer: (B)

Tuberculosis, varicella (chickenpox), and rubeola (measles) are all transmitted via airborne transmission. This mode of transmission involves the infection being spread through the air, particularly through small respiratory droplets or particles that can remain suspended in the air for extended periods. When an infected person coughs, sneezes, or talks, these tiny droplets can be inhaled by others who are in the vicinity, leading to new infections.

Airborne transmission is significant because it allows diseases to be spread over larger distances and can affect individuals who are not in immediate contact with the infected person. This is particularly important for healthcare settings where airborne precautions are necessary to protect vulnerable populations from highly contagious diseases such as tuberculosis, varicella, and rubeola. Understanding this mode of transmission helps in implementing effective infection control measures.
