Viral hepatitis is identified as a major global public health problem affecting several hundred million people. The severity of the hepatitis infection is not evenly distributed worldwide. Every year, 1.4 million people die from viral cirrhosis and hepatitis-related liver cancer. However, the majority of the infected population is unaware of their status. Therefore, prevention remains the best strategy to reduce viral hepatitis. Aim To study the epidemiology of viral hepatitis in Varna for the period 2014-2019. Materials Quick notifications, registration documents, reports, analyzes of laboratory tests of the Regional Center for Transfusion Hematology (RCTH) Varna and Virology Laboratory of RHI Varna, NCIPD Sofia, health education materials. Methods Documentary, statistical, laboratory, partial epidemiological analysis, graphic presentation of results. Results Viral hepatitis by settlement have a high relative share of 86.12% in cities as opposed to 11.55% in villages.
