Homelessness, unstable housing, and risk of HIV and hepatitis C virus acquisition among people who inject drugs: a systematic review and meta-analysis

Review (55 studies) found recent homelessness or unstable housing linked to increased risk of acquiring HIV (crude relative risk 1.55; 95% CI 1.23–1.95; p=0.0002) and hepatitis C (1.65; 1.44–1.90; p<0.0001) in this population vs. those who were not homeless or were stably housed.
