Question

Which among the following are communicable diseases?

• A. Diabetes
• B. Cholera
• C. Night-blindness
• D. Cancer

Answer 1

The correct option is B

Cholera

Communicable diseases spread from one person to another. The terms infectious and contagious are also used to describe the communicable disease.

In this case, cancer, and diabetes non-communicable diseases. In this condition, there are no germs of any kind and they cannot spread from one patient to another by contact or any other method. Night-blindness is a nutritional deficiency disease and hence non-communicable too.

Cholera is infectious. The cause of the disease is called pathogen and the transmission from one person to another is called infection.
