The geographic range of Angiostrongylus vasorum is expanding, leading to increased disease. Although observed cases of canine pulmonary angiostrongylosis have been dutifully reported in the literature, the state of biological knowledge remains too poor to predict future patterns of spread with any confidence. Nevertheless, there is an urgent need to identify areas that are likely to be suitable for parasite establishment. Preliminary attempts to do this using a climatic envelope approach suggest that several new areas are open to colonisation, even without invoking climate change. The risk of parasite importation into these areas should be mitigated, e.g. by restricting movement of dogs unless tested or treated for A. vasorum, and monitored by focused surveillance of definitive and intermediate hosts. These efforts will benefit from newly developed diagnostic tests.
管圆线虫的地理分布范围正在扩大，导致疾病增多。尽管文献中已如实报道了犬类肺管圆线虫病的观察病例，但生物学知识的现状仍非常匮乏，无法有把握地预测未来的传播模式。然而，迫切需要确定可能适合寄生虫定殖的区域。使用气候包络法进行的初步尝试表明，即使不考虑气候变化，几个新区域也有可能被定殖。应降低寄生虫传入这些区域的风险，例如通过限制犬类的移动，除非对其进行管圆线虫检测或治疗，并通过对终末宿主和中间宿主的重点监测进行监控。这些努力将受益于新开发的诊断测试。
