Primary prevention

Last modified at 11/4/2014 11:24 PM by Vladimir Prikazsky

Primary prevention takes place before a person develops the health outcome (usually disease) and in fact aims to prevent the health outcome. Success of primary prevention can be shown through indicators such as incidence and prevalence of disease going down.  Primary prevention usually targets the reservoir or source of infection, or aims to block the transmission route. Yet it could also strengthen the immune system, such as through immunisation.
