Answer:
Classification of Diseases – Types of Diseases
According to a very broad classification, diseases can also be classified under the following – physical diseases, mental diseases, infectious diseases, non- infectious diseases, deficiency diseases, inherited diseases, degenerative diseases, social diseases, self-inflicted diseases.
Depending on certain characteristics, diseases can also be classified as an acute disease where the onset of the disease is sudden, lasts for a short time, with rapid changes; and chronic diseases where the effects of the disease can last for months or years.

Even though the types of diseases can be classified very broadly, the classification of diseases into infectious and non-infectious diseases is considered very apt. Infectious diseases can be easily transmitted from one person to the other while the non-infectious disease cannot be transmitted.
