Infectious diseases are caused by small microbes invisible to the eye. Bacteria, protozoa, fungi & virus are the disease causing microorganisms in humans.

Firstly the illness is a disturbance in the normal well being of an individual or organism. This illness can be due to a disease or a disorder.

Disease is a disturbance in health condition due to some sort of infection by microbes like bacteria, protozoa, fungi and virus. Ex: Common-Cold, tuberculosis, malaria etc. This mostly involves some pain or inflammation.

While disorders are those defective health conditions caused due to malfunction of the body organs or systems. Ex: Diabetes, cancer, heart stroke etc. Here one feels uneasy and normal healthy life style is disturbed.
