DiseaseA disease is an abnormal condition that affects the body of an organism. It is

often construed as a medical condition associated with specific symptoms and signs.

There are four main types of disease: pathogenic disease, deficiency disease,hereditary disease, and physiological disease. Diseases can also be classified as

communicable and non-communicable disease.

BacteriaBacteria are microorganisms too small to see with the naked eye that exist in

virtually all environments in the world. Bacteria are a member of a large group of

unicellular or one-celled microorganisms that lack organelles and an organised

nucleus. There can be useful bacteria in the body of a living organism but others areknown to cause diseases.

Types of Diseases

Communicable and non-communicable

Communicable: These types of diseases can be transferred from an infected

person to a healthy person through different mediums such as air, food, water, skin

contact etc. These are caused due to pathogens which are disease-causing

microorganisms. Thats why these diseases are also called pathogenic diseases.

Examples: tuberculosis, common cold etc.

Non-communicable: These diseases do not spread from person to person. These

can be due to genetic reasons or due to malfunctioning of some organs. Examples:

cancer, mental disorders.
