Abstract
Chronic liver disease is an important health challenge in the world, where hepatitis B virus (HBV) infections are the main causes of liver insufficiency. HBV infection is a serious global health problem, with two billion people infected worldwide, and 350 million suffering from chronic HBV infection. The objective of this study was prevalence of Hepatitis B virus on Jeddah populations, Saudi Arabia. (HBV) was screened in serum and plasma by using Elisa test, samples were collected and stratified according to nationality into Saudi and non Saudi and according to gender into male and female and also according to age. Prevalence was calculated separately for each group and for studied population as a whole. Results showed that HBsAg were found in 6.11 % seropositive of sample in study populations, the prevalence of HBs Ag was higher in males than females it is 8 % among males and 5.61 % among females with significant difference (p<0.05). Also HBs Ag were found in 6.53 % of Saudi population and 1.79 % of non Saudi patient with no statistically significant difference (p>0.05). According to age results all positive samples were found in adult age while no positive sample at age under 15 years with no significant difference (p>0.05). Finally in this study we tried to draw attention through the study to create future strategies to deal with this virus and limit its spread in Saudi society. This study provides valuable information that can be used to examine the incidence of infection in the community and help focus the administration of a future HBV vaccine to appropriate target populations.
