Introduction
One of the main causes of disease is infection by microorganisms, with four types so far identified:
All exist as either:
- Primary pathogens (obligate): presence always corresponds with disease
- Secondary (opportunistic): prerequisites must be fulfilled before disease occurs
Microorganisms can enter the body by three routes:
- Contact: typically seen in dermatological infections
- Aerosol: typically respiratory infections
- Orofecal:typically enteric infections
