title: Transmission of hepatitis C in a pharmacologic study.
abstract: OBJECTIVE
  To describe an outbreak of hepatitis C in a clinical research study.
  
  
  METHODS
  Observational study.
  
  
  METHODS
  Tertiary-care hospital.
  
  
  METHODS
  Healthcare workers who volunteered to be subjects in a study of the metabolic effects of inhaled and oral corticosteroids who were unwittingly exposed to hepatitis C virus (HCV).
  
  
  METHODS
  Epidemiological investigation and serological analyses.
  
  
  RESULTS
  One chronic carrier of HCV was identified. Four fellow workers volunteering in the studies became infected with HCV, with 96% homology among strains. There was no evidence of spread from infected healthcare workers to patients on whom they had performed arterial punctures (2 of 214 positive, unrelated to each other and to the outbreak strain).
  
  
  CONCLUSIONS
  Infection control standards in clinical research must be maintained vigorously to prevent transmission of blood-borne pathogens such as HCV.
