Viral hepatitis A is a common disease, particularly in developing countries all staff and troops of the U.N. (United Nations) are vaccinated by the Havrix vaccine.
Till 1995 we did not vaccinate Czech troops which have operated in the area of former Yugoslavia.
The main goal of this study was to obtain data about the seroprevalence of hepatitis A antibody among the Czech U.N. troops before their departure to the conflict area and to optimalize the vaccination approach.
The serum samples were examined by the MEIA (Microparticle Enzyme Immunoassay) method in the fully automated system for immunoassays IMx in the Military Institute of Health in Ceské Budejovice.
We used HAVAB kits of Abbott Company. 692 serum samples (military staff of the Czech U.N. troops in Yugoslavia) were examined in 1991-1995, In the laboratory 19 samples were eliminated due to small amounts (less than 50 mul) or haemolysis. 673 (1991-65,1992-296,1993-265,1994-35,1995-12) were investigated.
The staff was divided into four age cohorts by decades (20-29,30-39,40-49,50-59) : 26.0%, 47.4%, 24.9% and 1.7%, respectively. there were 253 (37.4%) positive samples and 420 (62.6%) negative ones, ratio 1 : 1.7. The ratio of the positive and negative samples - immunity rate and seroprevalence - were 1 : 0.4 (26.2%), 1 : 0.6 (37.9%), 1 : 0.9 (46.4%) and 1 : 2.7 (72.7%), respectively in the age cohorts. (...)
