Dirofilariosis is a zoonotic disease that mainly affects dogs and cats, with a high risk to public health. The island of Gran Canaria (Spain) has been shown to be a hyperendemic area of infection and, therefore, a model for studying the evolution of the disease. The objective of this study was to track the prevalence and distribution of heartworm in dogs, cats, and residents of Gran Canaria from 1994 to 2020, using published and unpublished data. Blood samples from 5841 dogs, 1203 cats, and 1604 humans were collected in the years analyzed, considering geographical and isoclimatic factors. In 1994, a prevalence of of 67.02% in dogs was reported, while in 2020 it was 15.81%. In cats, the seroprevalence in 2010 was 33.03%, compared to 17.20% in 2020. The incidence of in humans in 2008 was 18.66%, while in 2020 it was 8.27%. For all study groups, temperate cold zone (TC) and temperate mild zone (TM) climates had the highest prevalence. Throughout these 20 years, the prevalence of heartworm disease has decreased. Despite this, it continues to be a hyperendemic island. This study highlights the importance of using the "One Health" perspective and the risks of contagion of the disease.
犬恶丝虫病是一种人畜共患病，主要影响犬类和猫类，对公众健康构成高风险。大加那利岛（西班牙）已被证明是感染的高度流行区，因此是研究该疾病演变的一个模型。本研究的目的是利用已发表和未发表的数据，追踪1994年至2020年大加那利岛犬类、猫类和居民中心丝虫的流行情况和分布。在分析的年份中，考虑到地理和等气候因素，收集了5841只犬、1203只猫和1604人的血样。1994年，报告犬类患病率为67.02%，而2020年为15.81%。在猫类中，2010年血清阳性率为33.03%，而2020年为17.20%。2008年人类中的发病率为18.66%，而2020年为8.27%。对于所有研究组，温带寒冷区（TC）和温带温和区（TM）气候的患病率最高。在这20年中，犬恶丝虫病的患病率有所下降。尽管如此，它仍然是一个高度流行的岛屿。本研究强调了采用“同一健康”视角的重要性以及该疾病的传播风险。
