The alveolar hydatid disease, also known as alveolar echinococcosis, of humans is certainly one of the most dangerous zoonoses worldwide. The disease is caused by - the fox tapeworm. Red foxes () are currently counted as the most important carriers (reservoirs) of in the Northern Hemisphere. The possible routes of infection of to humans are complex and still require research. Until now, it has been unknown whether eggs can be moved by wind at all. This analysis shows, based on calculations, that eggs can be transported by wind. Using a mathematical model, flight distances depending on wind speed and take-off heights are calculated for dense and less dense (coniferous) forest areas. The results - differentiated for seasons and as overall average - are based on mean values of wind speeds which were measured over a ten-year period in an experimental forest stand in the Solling (Germany). Due to their rate of descent, wind-related spreading of eggs is possible. The average flight distance covered by eggs in forest areas, depending on their starting altitude and wind speed, is between approximately 1.3 m and approximately 17 m. From the mathematical point of view, the wind factor can definitely be seen as one of the multiple vectors associated with environmental contamination by eggs. Consequently, the possible wind-borne spread of eggs poses an infection risk to humans that should be considered and requires further research.
人类的肺泡型包虫病，又称肺泡型包虫病，无疑是全球最危险的人畜共患病之一。这种疾病是由 - 狐狸绦虫引起的。红狐（）目前被认为是北半球最重要的（宿主）。向人类感染的可能途径很复杂，仍需要研究。到目前为止，还不清楚 卵是否可以被风吹动。这项分析表明，基于计算， 卵可以被风吹动。使用数学模型，根据风速和起飞高度计算了密集和稀疏（针叶林）森林地区的飞行距离。结果 - 根据季节和总体平均值进行了区分 - 基于在德国索林（德国）的一个实验林分中十年来测量的风速的平均值。由于其下降速度，与风有关的 卵传播是可能的。在森林地区，根据其起始高度和风速， 卵的平均飞行距离约为 1.3 米至 17 米。从数学的角度来看，风的因素肯定可以被视为与 卵环境污染相关的多种载体之一。因此， 卵可能随风传播会对人类造成感染风险，应予以考虑并需要进一步研究。
