[Serologic diagnosis of hemorrhagic fever with renal syndrome in Bosnia and Herzegovina in 2002].
AIM Results of the serologic confirmation of hemorrhagic fever with renal syndrome (HFRS) in patients with clinical picture and overt symptoms of the disease from particular areas in Bosnia and Herzegovina during 2002 are presented. METHODS A total of 146 sera from 100 clinically suspected patients were tested. The sera were tested for the presence of specific IgM antibodies to Hantaan and Puumala antigens by Elisa IgM "capture" test, and for the presence of specific antibodies to Hantaan, Puumala and Dobrava antigens by Elisa IgG test. DISCUSSION Most of the positive IgM reactions were recorded as cross reactions to Hantaan and Puumala antigens, and most of the positive IgG reactions as cross reactions to Hantaan and Dobrava antigens. The finding of antibodies in the sera of patients from Europe that react with Hantaan antigen are not associated with the infection with Hantaan, but with the infection with viruses that are genetically related with Hantaan. To date, HFRS caused by Puumala and Dobrava viruses has been verified in Bosnia and Herzegovina. CONCLUSION Using Elisa IgM "capture" test, acute hantavirus infection was serologically confirmed in 38% of clinically suspected patients with manifested symptoms from different areas of Bosnia and Herzegovina in 2002. The distribution of human hantavirus infection in Bosnia and Herzegovina was confirmed by the presence of specific hantavirus antibodies in patient sera.
