荷兰正面临Q热流行，奶山羊也受到牵连。生活在受影响农场附近的人风险更大。然而，在一些有严重Q热问题的农场周围没有报告人间病例。为了评估可能增加Q热传播或风险的当地环境条件的作用，我们收集了受感染农场周围5公里区域的植被，土地利用，土壤特征和天气条件的数据集。没有传播的地区植被密度较高，地下水条件相对较浅。植被和土壤湿度是贝氏柯克斯体从受感染农场传播给人类的相关因素，因为它们减少了可用于细菌传播的灰尘量。研究结果表明，集约化的山羊和绵羊饲养应避免在地区的特点是结合耕地与深层地下水和植被很少。
The Netherlands is facing a Q fever epidemic in which dairy goats are implicated. People living close to an affected farm have an increased risk. However, no human cases were reported around a number of farms with serious Q fever problems. To assess the role of local environmental conditions which may add to the transmission or risk of Q fever, we gathered datasets on vegetation, land use, soil characteristics, and weather conditions in 5 km areas around infected farms. Areas without transmission had a higher vegetation density and relatively shallow groundwater conditions. Vegetation and soil moisture are relevant factors in the transmission of Coxiella burnetii from infected farms to humans, by reducing the amount of dust available for dispersion of the bacteria. The findings suggest that intensive goat and sheep husbandry should be avoided in areas that are characterized by a combination of arable land with deep groundwater and little vegetation.
