The hepatitis B virus ( HBV ) is a global health problem . It is estimated that in the world there are about 350-400 million carriers of HBV surface antigen ( HBsAg ) 1 .

The prevalence in Spain is estimated at a 2-7 % and is considered a second intermediate prevalence.

For this reason , we want to evaluate what is the currently prevalence in our area of influence. There aren't recent studies to assess what is the current status of these patients ( how many , what risk factors which needs of treatment and with answer ...)
