[Hemorrhagic fever with renal syndrome in Croatia: incidence of infection in human and wild animal reservoirs].Lijec Vjesn. 1991 Sep-Oct; 113(9-10):320-3.LV
On the territory of Lika and Gorski Kotar a group of 300 forest workers and 260 persons from the general population were screened for Hantavirus antibodies (by the indirect immunofluorescence test). In the first group of examenees a mean of 1.6% were found positive, ranging from 0% (Gospić) to 3.2% (Ogulin). In the second groups a mean of 5.4% were positive, ranging from 4.4 to 8.9% (Delnice and Slunj, respectively). It is concluded that the Hantavirus infection rate in our natural foci of HFRS is higher than officially registered. Screening of micromammals for the presence of Hantavirus in their organs (lungs), using the direct immunofluorescence test, was undertaken on three locations: Planina Gornja (hillsides of the mountain Medvednica), a case of HFRS having been registered there previously, and Plitvicka Jezera and Velika Gorica (village of Kobilić) selected because of two previous epidemics of HFRS (1967 and 1989, respectively). On the first location, all 126 animals examined (10 different species) were Hantavirus negative. On the second location, 9 of the 165 animals examined (three species) were Hantavirus positive (5.4%), namely 6 bank voles (Clethrionomys glareolus) and three yellow-necked mice (Apodemus flavicollis). On the third location, where 141 animals was caught and examined (7 different species), 7 animals were positive (4.9%): 3 striped field mice (A. agrarius), 3 wood mice (A. sylvaticus) and 1 bank vole (Cl. glareolus). The findings suggest that in our natural foci of HFRS the circulation of the Hantavirus is sustained by several species of micromammals.
