The different ways an infectious agent passes from its source to a new host, which shape how each disease spreads and is prevented.
Source to host by a route: direct (contact, droplets, sex, placenta), indirect (vehicle, food, water, air), or vector-borne; break the chain of infection to control it.
Vector-Borne Disease Control
The ways of preventing diseases spread by insects and other vectors, by attacking the vector, protecting people, or both.
Water-Borne and Food-Borne Diseases
Infections spread by drinking contaminated water or eating contaminated food, a major cause of diarrhoea and outbreaks.
Disinfection and Sterilisation
Methods that reduce or remove germs from objects and surfaces to prevent the spread of infection.
