Classification of diseases
Diseases are categorised based on prevalence, occurrence or spread and duration.
=>Epidemics are the diseases based on prevalence that attack many people at the same time. e.g. plague.
=>Infectious diseases are the diseases based on occurrence or spread and duration. These are the diseases caused by micro-organisms like bacteria, virus, fungi and protozoa. These are spread from one person to another through air, food, water etc.
=>Non-infectious diseases are the diseases based on occurrence or spread. These are the diseases caused by genetic abnormalities. They are called non-communicable diseases as they do not spread from one person to another. e.g. cancer.
=>Acute diseases are the diseases based on duration. These diseases last for a short time without posing adverse effects on the health. e.g. common cold.
=>Chronic diseases are the diseases based on duration. Chronic diseases last for prolonged period with drastic effects on health. e.g. Diabetes.
