Hepatitis C Virus Intranasal Transmission: Pilot Study

(R21 DA19834 NIH/NIDA)
McMahon (Principal Investigator)
This multi-disciplinary study will develop new technologies and collect preliminary data to explore the virological, clinical and behavior factors that might facilitate hepatitis C virus (HCV) transmission through an intranasal route among noninjecting drug users.
