Hepatitis A antibodies: prevalence in Saudi Arabia
1Medical Biochemistry Department, College of Medicine & King Khalid Hospital, King Saud University, Riyadh, Saudi Arabia.
Hepatitis caused by hepatitis A virus (HAV) occurs at a variable prevalence in different countries, and the exposure to HAV is as high as 100% in some areas. There appears to be a close association between the prevalence of anti-HAV and socioeconomic status and age. In this paper, we report the prevalence of antibody to HAV (anti-HAV) in five regions covering different parts of Saudi Arabia. The results of this study show that the overall prevalence of anti-HAV is 96% and 95.1% in the total male and female population respectively. In different age groups the prevalence varies from 78-100% with a concomitant increase with age. These results show that the rate of exposure to HAV is high in Saudi Arabia and predominant exposure occurs in early childhood.
