Hantaviruses are RNA viruses of the Bunyaviridae family, represented in the Czech Republic by three genospecies: Dobrava-Belgrade, Puumala and Tula. They persist in natural foci of infection. In 2004 to 2009, a local outbreak with 18 reported cases of nephropathia epidemica caused by Puumala hantavirus occurred in the Sumava mountains and foothills and was spacially associated with another outbreak in Lower Bavaria, Germany. In the Jeleni locality in the Sumava mountains at 880 m above sea level, we identified a natural focus of infection suspected to be the source of hantavirus infection in forest workers. The focus was characterized geobotanically as a montane mixed forest with the predominance of beeches within the association Dentario enneaphylli-Fagetum, alliance Fagion, sub-alliance Eu-Fagenion, in a cold climate region with a podzolic soil. The biocenoses where hantaviruses are circulating typically show higher microclimate humidity. Their characteristization can be helpful in predicting where hantaviruses are likely to circulate.
汉坦病毒是布尼亚病毒科的RNA病毒，在捷克共和国有三种基因型代表：多布拉瓦-贝尔格莱德型、普马拉型和图拉型。它们在自然疫源地中持续存在。2004年至2009年，苏马瓦山脉及山麓地区发生了由普马拉汉坦病毒引起的18例流行性肾病局部疫情，且在空间上与德国下巴伐利亚的另一起疫情相关。在苏马瓦山脉海拔880米的耶莱尼地区，我们确定了一个自然疫源地，怀疑是森林工人感染汉坦病毒的源头。该疫源地在地理植物学上的特征是山地混交林，在齿叶九叶芹-山毛榉林群系、山毛榉林联盟、亚联盟真山毛榉亚联盟中以山毛榉为主，位于一个寒冷气候地区，土壤为灰化土。汉坦病毒传播的生物群落通常显示出较高的小气候湿度。对它们的特征描述有助于预测汉坦病毒可能传播的地点。
