Most communicable diseases are either bacterial or viral and infect the respiratory tract.

Communicable, or infectious diseases, are generated by microorganisms such as parasites, fungi, bacteria, and viruses, which can be spread, directly or indirectly, from one person to person.

A majority of upper respiratory diseases are due to self-limited viral epidemics. Occasionally, bacterial germs may produce upper respiratory infections. Most often, upper respiratory virus is communicable and can spread from person to person by breathing respiratory droplets from coughing or sneezing.

By definition, communicable diseases are diseases that can be passed from one person to another. Also, not all communicable diseases are caused by bacteria only nor virus only. So therefore, the answer would be option A. The statement that BEST describes common communicable diseases is this: Most communicable diseases are either bacterial or viral and infect the respiratory tract. Hope this answer helps.
