This study evaluated the epidemiological behavior of the hepatitis A in Paraná state and compared the costs of the disease and the vaccination. This is an epidemiological descriptive study including a pharmacoeconomy analysis. We collected information in the national database reported cases (SINAN), in the mortality information system (SIM) and in the hospital information system (AIH) among 2000/2003 (Paraná State Public Health Department). We estimated the probability of one cohort of children to acquire hepatitis A during their lifetime and the costs with their treatment. We compared those costs with the cost of vaccinating the children. 14,682 hepatitis A cases were registered during the period studied, and 12,102 (82.4 percent) occurred in the 0-15 years-old age group. The annual incidence in the general population was 37.5/100,000. We observed 20 deaths caused by this disease; 7 of those occurred by liver failure. The estimated costs with the disease included the hospital costs, liver transplantation, liver failure treatment, and laboratory tests were high. The price of the vaccine is 10 USD/dose. Two doses are necessary to get the protection. The results showed a positive cost - benefit relation when we vaccinate children. We save 2.26 USD in treatment for each dollar invested in the vaccine. Paraná record high number of hepatitis A cases each year. We confirmed the positive cost - benefit relation when we vaccinate children against hepatitis A, reducing suffering, hospitalization, death and social costs. Vaccination against hepatitis A should be recommended in the routine of immunization program in Paraná state.
