- Process of Infection (POV: microorganism)
- 4. Spread
- Localised infection without spread to other parts of body - immune system prevents spread
- Highly invasive infections may enter lymphatics, blood, & internal organs
- Successful spread - relies of virulence (severity of disease) factors - e.g. adhesion molecules
- 3. Multiplication
- Warm, nutrient filled host environment allows for rapid multiplication of infected cells
- 4. Spread
- A microorganism is any organism too small to be seen by the naked eye
