Pathogen - reduction or eradication
Patient - imporved health, immunity
Practice - behavioural change, protective equipment
Place - environmental engineering
What are the consequences of infection control
Good - decreased incidence or elimination of pathogen
Bad - decreased exposure meaning increased susceptibility, later age of exposure with an increased severity
