Disease due to infection is the outcome of interaction between micro-organisms or other agents and the defense mechanism of the body. Illnesses that are passed from one person to another by bacteria, viruses, fungi, reckettsiae, protozoa or parasitic worms are infectious. Some harmless organism which lives normally in our body under certain circumstances can cause illness which occurs through insects, animals, consumption of contaminated foods or by exchange of body fluids etc.

There occur fevers, fatigue, cough, bodyache or other symptoms. Five most infectious diseases are Hepatitis B & C, Malaria, Dengue and Tuberculosis. HIV/AIDS, tuberculosis, pneumonia and diarrhea are really deadly. WHO says lower respiratory tract infections, diarrhoeal diseases and tuberculosis are the worst killer.

Infections sometimes originate from the patient (autogenous), usually from skin, nasopharynx , bowel or from external sources i.e from another person who is suffering from infection or carrying the organisms. It may be mentioned that human body is not without defense. The most important barriers to invasion of human body by infectious diseases are skin and mucous membrane. Besides, body is equipped with proper weapon i.e our immune system. Carriers of infectious diseases are apparently healthy and may harbor organisms in the throat (Diphtheria), bowel (Salmonella), blood (hepatitis B, HIV). The sources of infections may be water (Cholera), milk (tuberculosis), food (Botulism), animals (Rabbis), birds (Psittacosis), soil (legionnaeres’ diarrhoea).

Many bacteria and viruses thrive in moisture and spitting, coughing and sneezing keep them in circulation. We should be careful about these habits and our food, water, body fluids and bloods.
