Epidemiological aspects of hepatitis B in Palermo: changes in HBV spread.
Prevalence of HBV infection in Palermo was investigated in 1989, in comparison with similar data observed in 1982. Between September 1988 and April 1989, 1001 serum samples taken from healthy individuals or from patients with pathology unrelated to liver diseases, in the age groups 0 to 59 years, were collected. Prevalence of HBsAg and anti-HBc was, respectively, 2.7% and 24.3% in males, 2.3% and 19% in females. Prevalence was inversely related to socioeconomic level as defined by occupation, educational level and area of residence. Prevalence of HBV markers in 1989 was compared with that of a sample of sera taken in 1982 and stored at -20 degrees C. Prevalence was lower in 1989 for age groups under 20, while no difference was seen in older age groups.
