Hepatitis C virus outbreak in a haemodialysis unit: learning from failures

Area of Science:

• Infectious Diseases
• Hepatology
• Public Health

Background:

• Hepatitis C virus (HCV) poses a significant risk in healthcare settings, particularly for vulnerable populations like hemodialysis patients.
• Nosocomial transmission of bloodborne infections requires vigilant adherence to infection control protocols.

Purpose of the Study:

• To investigate an outbreak of hepatitis C virus (HCV) in an Italian hemodialysis (HD) center.
• To identify potential transmission routes and contributing factors to HCV spread within the HD unit.

Main Methods:

• Observational analysis of a small cluster of HCV infections among hemodialysis patients.
• Epidemiological investigation to identify commonalities in exposure and potential breaches in standard precautions.

Main Results:

• Three hemodialysis patients acquired infection with the same HCV strain.
• Infection occurred in patients sharing room and shifts with a chronically infected HCV patient.
• Multiple potential transmission modes were observed, but a definitive route for HCV spread was not identified.

Conclusions:

• This outbreak underscores the risk of nosocomial HCV transmission in hemodialysis settings.
• Breaches in standard precautions for bloodborne infections by healthcare staff can facilitate HCV spread.
• Continuous reinforcement of infection control measures is critical to prevent HCV transmission among hemodialysis patients.
