General ways
Specific ways
General ways of prevention of infectious diseases : These include
Sanitation : Public hygiene is one basic key to the prevention of infectious (communicable) diseases.
Eradication of vectors : Vector-borne infections can be prevented by providing clean environments. The breeding places of vectors should be destroyed and adult vectors killed by suitable methods.
Sterilization : Patients’s surroundings and articles of use should be sterilized. Soap, phenyl, dettol, and antiseptic lotion may be used wherever necessary.
Isolation : A person suffering from an infectious disease shoule be kept in isolation so that others do not catch infection from him.
Education : People should be educated about the infectious disease so that they may protect themselves against such infections.
Proper and sufficient food : Availability of proper (nutritious) and sufficient food to everyone will make people healthy to resist infections.
Proper immunization against diseases.
Specific ways of prevention of infectious diseases : Specific ways of prevention of infectious diseases relate to a peculiar property of the immune system that usually fights off microbial infections. This is the basis of the principle of immunisation.
