At a glance
- Infection risk follows a defect in a specific arm of host defence. Name the defect and the likely organisms follow.
- Population risk in Australia tracks crowding, housing, remoteness, migration and injecting drug use as much as biology.
- Paper 1 uses this to ask which organism a patient is at risk of, why, and which screening or prophylaxis the mechanism justifies.
