Invasive diagnostic or therapeutic procedures may be a routefor the transmission of the hepatitis C virus (HCV).1,2,3,4,5In a study of patients in a gastrointestinal-disease unit, endoscopicbiopsies were found to be an independent risk factor for HCVinfection.6 We report the transmission of HCV during colonoscopyfrom a person known to have HCV infection to two other patients.The patient-to-patient transmission was ascertained by sequencingthe nucleotides in the various HCV isolates.
Case Report
A 55-year-old man (Patient 1) and his 54-year-old wife (Patient2) were referred in October 1995. In June 1995, both had hadhepatitis-like illnesses, with nausea, . . . [Full Text of this Article]
