title: Dynamics of viral hepatitis B epidemiological process in Plovdiv region.
abstract: Registration of viral hepatitis cases by type started in 1982 in Bulgaria, and in August 1991 Bulgaria launched a mass immunisation programme to vaccinate infants against hepatitis B. The objective of this dissertation thesis is to study the epidemiological status of hepatitis B virus (HBV) infection in Plovdiv region (the second largest administrative region in Bulgaria with a population of 683,027 people in 2011), and assess the epidemiological process dynamics as a result of the administration of a recombinant vaccine that has been used over the past two decades.
