Hepatitis B is endemic in Tunisia. His prevalence was evaluated at 5.5% in 1990. The aim of this study is to estimate the prevalence of this disease in the last years in Tunisia.
it was a retrospective study about all the blood donors in the Military Center of Blood Transfusion between 2000 and 2011.
The Ag HBs was systematic for every blood donation, by immuno-enzymatic reaction.
In this period, 198157 blood donors were compiled. These donors were, for 95%, young men, between 20 and 25 years, from all the parts of the country.
This study showed:
A net decrease in prevalence of hepatitis B in 12 years: from 3.54% in 2000 to 0.8% in 2011.
A regional disparity of this prevalence.
No identification of a population at risk.
The improvement of hygiene and the use of disposable syringes in hospitals can explain this decrease of the prevalence; HVB vaccination began in 1995 and didn’t affect the sample of the study.
Hepatitis B is still a public health problem in Tunisia. Vaccination and better socio-economic condition will lead in short term to the decrease of the HVB prevalence, started since the 90’s.
