What factors should be considered when diagnosing a person with an infection?
- age
- gender

- pathological state

- contiguous (direct) spread
- inoculation
- haematogenous (spread through blood)

- vertical transmission
4
Outline the stages of an infection leading to host damage
1) attachment of the pathogen
2) attachment leads to toxin production and interaction with host defences which both directly lead to host damage
3) interaction with host defences causes inflammation, which leads to host damage
5
What three components make up a diagnosis of an infection?
