Infection is a noun used to describe the invasion of multiple microorganisms in a bodily part or tissue. This may cause a disease or illness through the diversion into cells and toxic mechanisms.
Colonisation is a noun which describes the process of establishing an area. It includes the spreading of a species to a new, unharmed area.
Infection can be in the body for a number of weeks, but depending on the type of infection will determine to which area of the body the infection controls. ‘Systemic infection’ is the spreading of the infection throughout the body. The infection is contained in the blood stream and carried to parts of the body; for example hepatitis. ‘Localised infection’ is when the disease is restricted to a specific part of the body; for example a mouth ulcer or conjunctivitis in the eye.
