Assessment of the risk of HIV transmission
The risk of HIV transmission through a single exposure is determined by:
- The nature of the exposure with its estimated risk/exposure (Table 1)
- The risk that the source is HIV positive, if their status is unknown (Table 2)
- Factors associated with the source and exposed individuals.
Risk of HIV transmission
= risk per exposure x risk of source being HIV positive
= risk per exposure x risk of source being HIV positive
