Infectious Diseases
Infectious diseases or communicable disease : An infectious disease that can be spread from one infected individual to another is called a communicable disease. An infectious disease can be spread from an infected person to a healthy person in many ways such as through food, water, air, direct contact, through a disease carrier like a mosquito, etc. Some infectious diseases are not communicable.
For example, tetanus is an infectious disease which affects the nerves and muscles of the patient. It is caused by a bacterium which enters the body when a wound comes in contact with contaminated soil or animal wastes. But tetanus cannot be spread from person to person. So, it is not a communicable disease.
Infectious diseases are caused by some biological agents (pathogens) such as viruses, bacteria, fungi and single- celled animal protozoans, etc. The presence of an infectious agent may affect the normal body function of the individual, leading to a disease. These can rapidly spread from one person to another by various means such as water, air, food, insects (vectors) or by physical contact. Some infectious diseases that develop and spread rapidly to many people are called epidemic diseases.
Infectious Agents: The unicellular or multicellular organisms that cause infection are called infectious agents. These disease causing organisms are also called pathogens and they are classified into a wide range of categories. Some of them are viruses, bacteria, fungi, protozoans, etc.
