Prevalence and temporal evolution of the infection by the acanthocephalan Macracanthorhynchus hirudinaceus is studied in the Valencian Community (Eastern Spain), a region only recently fully colonized by the expanding native Eurasian wild boar (Sus scrofa). For 8 years, a total of 1486 wild boars were sampled in order to look for the parasite. The mean prevalence was 20.7% (95% CI, 18.6-22.8; 307/1486). We observed an increasing trend through time, both in the number of wild boars and affected districts. The prevalence of M. hirudinaceus rose in parallel to the annual capture of wild boars, and its presence has been expanding towards the East. A hotspot of M. hirudinaceus is located to the west of the study area, in Muela de Cortes Game Reserve, where 89.6% of the wild boars were positive for the infection, constituting one of the world's highest known prevalence areas.
在西班牙东部的瓦伦西亚社区（Valencian Community），棘头虫属棘头虫（Macracanthorhynchus hirudinaceus）的感染流行率和时间演变进行了研究。该地区最近才被不断扩张的本地欧亚野猪（Sus scrofa）完全殖民。8 年来，共采集了 1486 头野猪样本，以寻找寄生虫。寄生虫的平均流行率为 20.7%（95%置信区间，18.6-22.8；307/1486）。我们观察到随着时间的推移，无论是野猪的数量还是受影响的地区，流行率都呈上升趋势。棘头虫属棘头虫的流行率与野猪的年捕获量呈平行上升趋势，其存在范围也在向东部扩张。棘头虫属棘头虫的一个热点位于研究区域以西的莫拉·德·科尔特斯狩猎保护区（Muela de Cortes Game Reserve），该地区 89.6%的野猪受到感染，是世界上已知的感染率最高的地区之一。
