In medicine, diseases are divided into two broad groups:-Communicable and Non-communicable diseases. Simply speaking, communicable diseases spread to persons within a community, state, country and to several parts of the world in a pandemic. On the other hand, a non-communicable disease cannot spread to any other person in a community from a person who has it; it remains with the person who has it.

However, non-communicable diseases accounted for almost 60% of deaths; thus while they account for less number of diseases, non-communicable diseases account for more deaths.
