Abstract
Summary Age-specific prevalence of antibody to hepatitis C virus (anti-HCV) was studied in 831 Saudis (441 males, 390 females; 1–53 years old) from Al Baha region, south-west Saudi Arabia. There was a gradual exposure to H CV early in life with a gradual increase with age, reaching a peak of 5.3% in the 30–40 years age group. The overall prevalence was 3.6% and 3.1% in males and females, respectively, with no statistical difference. Comparison of positivity in family members of seven anti-HCV-positive index cases (15/44) with those of five anti-HCV-negative index cases (2/44) showed a statistically significant association (x210.5 with Yates' correction). This points to intrafamilial transmission of HCV as a route of spread among the Saudi population.
