Dear student,
 
Any deviation from the normal functioning or state of incomplete physical or mental well being is called disease. Disease is a condition that impairs the proper functioning of the body or one of its parts. The diseases may be of different types, such as :
(a) Acute disease: Which lasts for short duration. Example: Common cold. jaundice
(b) Chronic disease: Which lasts for very long period. Example: Tuberculosis, diabetes. 
(c) Infectious disease: Which can be transmitted from one individual to another directly or indirectly. Example: Influenza, tuberculosis
(d) Non-infectious disease: Which are not transmitted from one individual to another. Example: Cancer, marasmus.
