This annual national report describes trends in the extent of infections and associated risks and behaviours among people who inject drugs in the UK to the end of 2016. This information is essential to understanding the extent of these infections, the risk factors for their acquisition, and for monitoring the effectiveness of prevention measures.
- Hepatitis C prevalence remains high and half of those infected are undiagnosed
- HIV levels remain low, but risks continue
- Hepatitis B remains rare, but vaccine uptake needs to be sustained, particularly in younger age groups
- Bacterial infections continue to be a problem
- Injecting risk behaviours have declined but remain a problem
- Changing patterns of psychoactive drug injection remain a concern
- Provision of effective interventions needs to be maintained and optimised
