Summary
Laboratory-associated hepatitis cases significantly decreased between 1970-1976, with only nine reported. This suggests hepatitis control measures in British labs have been highly effective.
Area of Science:
- Clinical pathology
- Infectious disease epidemiology
Background:
- Laboratory-acquired infections pose risks to healthcare professionals.
- Previous studies indicated a need for effective control measures against hepatitis in clinical settings.
Purpose of the Study:
- To assess the incidence of hepatitis in British clinical laboratories following the implementation of control measures.
- To evaluate the effectiveness of these control strategies over time.
Main Methods:
- A questionnaire survey was administered to members of the Association of Clinical Pathologists.
- Data collected covered the period from 1970 to 1976, building on earlier surveys.
- Reported cases of hepatitis, including hepatitis B, were analyzed.
Main Results:
- A total of nine hepatitis cases were reported across the surveyed laboratories.
- Three of the reported cases were specifically identified as hepatitis B.
- The annual attack rate for hepatitis was found to be 34 per 100,000, a significant reduction.
Conclusions:
- The findings indicate a substantial decrease in hepatitis incidence compared to earlier periods.
- Implemented control measures in British laboratories appear to have been considerably successful in reducing hepatitis transmission.
