Purpose of the Study:
- To analyze the epidemiology of a Hepatitis A outbreak in West Scotland in 1981.
- To identify key demographic and risk factors associated with the increased cases.
Main Methods:
- Laboratory-confirmed case data analysis.
- Review of viral hepatitis notifications.
- Demographic and epidemiological risk factor assessment.
Main Results:
- 151 laboratory-confirmed Hepatitis A cases in West Scotland in 1981, a >3-fold increase.
- Majority of cases (54%) in children under 15; a secondary rise in the 21-30 age group.
- Key transmission factors included contact with known cases (25%) and international travel (16%).
