Question

Which of the following diseases spread through air?

• A. Dysentery, cholera and typhoid
• B. Ulcer, heart attack and appendicitis
• C. Common cold and influenza
• D. Acquired immuno deficiency syndrome

Answer 1

The correct option is C Common cold and influenza

Airborne diseases are caused by pathogenic microbes small enough to be discharged from an infected person via coughing, sneezing, laughing and close personal contact or aerosolization of the microbe. The discharged microbes remain suspended in the air on dust particles, respiratory and water droplets. Illness is caused when the microbe is inhaled or contacts mucus membranes or when secretions remaining on a surface are touched. Many common infections can spread by airborne transmission at least in some cases, including: anthrax (inhalational), chicken pox, influenza, measles, smallpox, and tuberculosis.

Therefore, the correct answer is option C.
