Abstract

The first cases of Hantavirus infection in Turkey were reported in early 2009 in the Zonguldak and Bartin provinces. The aim of this study was to investigate the presence of Hantavirus antibodies in patients who had clinical and laboratory findings that were potentially associated with Hantavirus infection prior to the epidemic in Bartin in 2009. After screening 314,577 medical records from between 2007 and 2009, the clinical and laboratory data for 442 patients meeting the criteria of coexistent thrombocytopenia, and elevated urea and creatinine levels were transferred to a statistical program. Home visits were made to 170 patients, 84 of whom consented to participate in the study. The participants completed a questionnaire and provided a blood sample. Commercial anti-Hantavirus IgG and IgM ELISA and immunoblotting assays were used, with seropositive samples being confirmed by focus reduction neutralization tests (FRNT). ELISA and/or immunoblotting assays detected 10 positive samples; however, only 7 of these were recorded as positive by FRNT. FRNT positivity was significantly associated with female sex, the presence of a barn near to the house, and working in a forest (P < 0.05). In a Hantavirus endemic region, physicians must keep in mind that thrombocytopenia, and elevated urea and creatinine levels may indicate Hantavirus infection.
