There could be various causes for a disease

Infectious – These include infectious external causes like micro-organisms. Organisms like virus, bacteria, and other micro-organisms can cause diseases in a person. For example, diarrhoea is caused by viral or bacterial infection. Diseases caused by these infectious causes are called infectious diseases.

Non- infectious - These include non- infectious causes and that can be internal or external. For example, some cancers caused by genetic abnormalities, high blood pressure caused by excessive weight and loss of exercise, malfunctioning of any body part as in heart attack and arthritis, allergies, lack of nutrients can cause marasmus, pollution causing respiratory problems, etc. Diseases caused by these non- infectious causes are called non-infectious diseases.
