Non-communicable diseases are diseases that cannot be transmitted from person to person. They are noninfectious health conditions that cannot be spread from one person to another. They last for a long period of time. Non-communicable diseases are also known as chronic diseases.
They have many causes but are never caused by germs, bacteria or other living organisms that attack the body. They are rather caused by:
Atomic fallout: Deposition on the surface of the earth of radioactive particles, released into the atmosphere as a result of nuclear explosions and by discharge from nuclear-power and atomic installations.
Chemical fallouts: Chemical agents such as nerve gas, or biological weapons such as the contagious disease anthrax.
Physiological failures of the tissues: Inability of the body tissues to work properly
Brain damage: Injury to the brain tissue that can impair its ability to function
Congenital problems: This is also called congenital disorders, any abnormalities of structure or function that are present at birth.
