Hemorrhagic fever with renal syndrome in Montenegro

Abstract

The objective of the study was to analyze the epidemiological features of hemorrhagic fever with renal syndrome (HFRS) in Montenegro. The study included 169 cases of HFRS diagnosed in the period between 1995 and 2005 according to the clinical symptoms and serological confirmation. For the analysis of the demographic characteristics of the cases, as well as of the chronological and topographical features of the disease, a descriptive epidemiological method was employed. The average incidence rate in the observed period was 2.6 per 100,000. In the observed period, 8 people died; the average case fatality rate was 4.8% (range: 0.1-15%). Among the diseased persons, 116 were males and 53 were females; most of the cases were adults. The greatest number of HFRS cases occurred during the summer months. The highest incidence rates were registered in the northeastern, rural part of the country. The most frequent type of hantaviruses in Montenegro were Dobrava-Belgrade and Hantaan, carried by rodent species, i.e., the yellow-neck mouse and the striped-field mouse. It is likely that HFRS in Montenegro will become more common in the near future, unless public health control measures are taken.
