2000年至2002年，在法国阿登省，通过捕获-标记-再捕获协议收集了自然感染汉坦病毒Puumala（PUUV）的银行田鼠，Myodes glareolus的流行病学数据。在位于两个州（弗莱泽和蒙泰姆）的两个森林中设立了四个监测诱捕地点。在8820个诱捕夜中，我们捕获了912只河岸田鼠，对应于557个不同的个体，总体诱捕成功率为10- 34%。PUUV平均血清阳性率为22.4%。北欧国家报告的系统特征在法国得到证实。PUUV血清阳性率和啮齿类动物的丰度呈弱相关。成年田鼠更频繁的抗体阳性，但性别之间没有差异。捕获了抗PUUV血清阳性田鼠，在两个森林中均观察到高血清阳性率，研究期间弗莱泽州未报告人感染。其中一个网站的四个表现出特殊的感染动态。其中田鼠体重与感染风险呈负相关。
Epidemiological data from bank voles, Myodes glareolus, naturally infected by the hantavirus Puumala (PUUV) were collected by a capture-mark-recapture protocol from 2000 to 2002 in the French department of Ardennes. Four monitored trapping sites were established in two forests located in two cantons (Flize and Montherme). We captured 912 bank voles corresponding to 557 different individuals during 8820 trapping nights for an overall trapping success of 10-34%. The average PUUV seroprevalence was 22.4%. Characteristics of the system reported in North European Countries are confirmed in France. PUUV seroprevalence and abundance of rodents appeared weakly linked. Adult voles were more frequently antibody-positive, but no difference between sexes was established. Anti-PUUV seropositive voles were captured and high seroprevalence was observed from both forests, without human infection reported in Flize canton during the study. One site among the four exhibited peculiar infection dynamics. where vole weight and infection risk were negatively correlated.
