Summary
Hepatitis B virus (HBV) infections in hospital staff occurred outside high-risk areas. Many patients had unknown HBs-antigenemia, highlighting the need for universal precautions and vaccination.
Area of Science:
- Hepatology
- Infectious Diseases
- Occupational Health
Context:
- Hepatitis B virus (HBV) poses a significant risk in healthcare settings.
- Hospital personnel and inpatients are susceptible to HBV transmission.
- Previous studies identified high-risk areas for HBV infection within hospitals.
Purpose:
- To investigate the prevalence and sources of HBV infections among hospital personnel over five years.
- To assess the rate of previously undiagnosed HBs-antigenemia in inpatients.
- To evaluate the effectiveness of current infection control measures and recommend improvements.
Summary:
- A five-year study recorded subclinical and clinical hepatitis B virus (HBV) infections in hospital personnel.
- While laboratories, dialysis units, and surgical wards were identified as high-risk areas, 50% of HBV infections occurred elsewhere.
- Over 50% of inpatients with HBs-antigenemia were unaware of their infection, often being treated for other conditions.
Impact:
- Findings underscore the need for stringent infection control, including avoiding even minimal blood contamination.
- Recommends universal hepatitis B vaccination for all hospital personnel.
- Advocates for routine HBs-antigen screening in all inpatients to identify asymptomatic carriers and prevent further transmission.
