People with no apparent risk factors
Clusters of transmission of HIV or hepatitis C through artificial insemination, the blood supply and through minor surgical procedures have occasionally been identified through contact tracing in Australia.
The management of these cases requires:
- Exclusion of sexual partners as sources of infection for the index patient
- Expert reassessment of the risk history of individuals
- Pooling of data on cases
- Systematic review of the investigation
- Specialised techniques of characterising viral isolates
Given the organisational, medico-legal and social complexity of these investigations, such patients should be referred to specialist services for contact tracing.
