Clinical course and outcome of a nosocomial outbreak of hepatitis C in a urology ward
Journal of Hospital Infection (2007) 67, 86-91
Summary This paper describes a prospective study of the clinical course and outcome of a nosocomial outbreak of hepatitis C virus (HCV) infection in six male urology patients at a hospital in Stara Zagora, Bulgaria. These patients had been previously hospitalised in the urology ward, during which all had received intravenous therapy. Approximately three weeks later, all six were admitted to the infectious diseases unit with acute hepatitis,shown to be caused by HCV genotype 1b. The diagnosis was confirmed by polymerase chain reaction during the first week of their hospital stay. Infected patients were followed up for 30 months following diagnosis and 54 potential contacts for 6 months post-exposure. Four patients recovered completely; one developed chronic HCV infection and one died. The latter already had cirrhosis due to co-infection with hepatitis B virus. The investigation established the index case as a patient with chronic hepatitis C, who had been an in-patient on the same ward at the same time. The most likely route of transmission was intravenous heparin flushes administered with a common syringe. Contrary to the common assumption that acute HCV infection often leads to chronic disease, only one chronic case was observed during the 30-month period of investigation. |
