Hygiene: washing hands and cleaning cooking items
Kill vectors: insecticides which kill the vectors
Vaccination:
Isolate infected individuals: stops spread and controls contamination

By air: carried and spread from one organism to another in the air like flu or the common cold
Direct contact: spread by direct contact of an infected organism with a health one eg STDs or plant diseases
Water: pathogen enters your body via your digestive system through contaminated water diseases like cholera
