Which of the following is NOT an example of a communicable disease?

Hypertension is not classified as a communicable disease because it is primarily a non-infectious, chronic condition that stems from various factors, including lifestyle choices, genetics, and environmental influences. Unlike communicable diseases such as chicken pox, diphtheria, and Ebola, which can spread from person to person through pathogens like viruses or bacteria, hypertension does not spread in a similar manner. It is often managed through medication and lifestyle changes rather than through methods of infection control that apply to communicable diseases, highlighting the fundamental differences between infectious and non-infectious health conditions.
