Vector-borne helminths of dogs and humans in Europe
Open accessAbstract
Presently, 45% of the total human population of Europe, as well as their domestic and companion animals, are exposed to the risk of vector-borne helminths (VBH) causing diseases. A plethora of intrinsic biological and extrinsic factors affect the relationship among helminths, vectors and animal hosts, in a constantly changing environment. Although canine dirofilarioses by Dirofilaria immitis and Dirofilaria repens are key examples of the success of VBH spreading into non-endemic areas, another example is represented by Thelazia callipaeda eyeworm, an emergent pathogen of dogs, cats and humans in several regions of Europe. The recent finding of Onchocerca lupi causing canine and human infestation in Europe and overseas renders the picture of VBH even more complicated. Similarly, tick-transmitted filarioids of the genus Cercopithifilaria infesting the skin of dogs were recently shown to be widespread in Europe. Although for most of the VBH above there is an increasing accumulation of research data on their distribution at national level, the overall impact of the diseases they cause in dogs and humans is not fully recognised in many aspects. This review investigates the reasons underlying the increasing trend in distribution of VBH in Europe and discusses the diagnostic and control strategies currently available. In addition, this article provides the authors' opinion on some topics related to VBH that would deserve further scientific investigation.

Written from the paper’s full text.
TL;DR
This narrative review examines vector-borne helminths (VBH) of dogs and humans in Europe, focusing on Dirofilaria immitis, Dirofilaria repens, Thelazia callipaeda, Onchocerca lupi, Cercopithifilaria spp., and Acanthocheilonema spp. It argues that VBH distribution is increasing due to vector spread, environmental change, and host-vector factors, while diagnosis, prevention, and control remain uneven and under-recognized.
Key findings
- 45% of Europe’s total human population, along with domestic and companion animals, is exposed to the risk of VBH.
- Dirofilaria immitis and D. repens are key spreading filarioids; adult females develop in 120–180 and 189–259 days, respectively, and main European vectors include Aedimorphus vexans, Culex pipiens pipiens, and Stegomyia albopicta.
- Thelazia callipaeda is endemic in France, Switzerland, Spain, and Portugal at latitudes between 39° and 46° N; in southern Italy, prevalence reaches about 60% in dogs and 49.3% in foxes, with human cases reported in north-western Italy, south-eastern France, and Spain.
- Cercopithifilaria sp.1 has been diagnosed in dogs from Spain, Greece, and southern Italy with prevalence rates up to 21.6%, and Rhipicephalus sanguineus has been experimentally demonstrated as its intermediate host; Onchocerca lupi has been found in dogs in southern and Central Europe and the United States, with human cases in Turkey and Tunisia.
Methods
- Narrative review; no systematic search strategy, inclusion criteria, or meta-analysis is described.
- Synthesizes published literature on VBH distribution, vectors, host-vector interactions, human impact, diagnosis, prevention, and treatment, and includes the authors’ opinion on research priorities.
- Includes distribution maps and a table of macrocyclic lactones licensed for prevention of Dirofilaria immitis and/or D. repens in dogs.
Limitations
- Stated: the overall impact of VBH diseases in dogs and humans is not fully recognized; biological mechanisms behind increased VBH cases remain uncertain; vector roles for many VBH are lacking; some VBH are poorly investigated, and lack of awareness constrains management and control.
- Stated: human VBH impact in Europe is likely underestimated because physicians may lack awareness of exotic parasites and misidentify cases.
- Evident from the text: as a narrative review, it provides no primary data, no systematic search or quality appraisal, and its conclusions and future-research opinions are authors’ synthesis.

The Discussion (page not provided) cites a predictive geoclimatic model identifying areas where the T. callipaeda vector could be present, and the Conclusions discuss possible emergence of human cases in Dordogne. The paper does not say the model predicts an increase in infestation reports over the next years in areas currently considered non-endemic. (LLM, conf=0.80)

The Discussion (page unavailable) predicts that new cases are likely to emerge in other areas of Spain and Europe. The Background describes an ecological niche model suggesting that infection could have spread into previously non-endemic areas. But the paper does not identify that model as GARP or base its prediction of future cases on it; the Discussion bases that prediction on observed prevalence and epidemiological knowledge. (LLM, conf=0.86)

The Background says disease mapping identified large areas of Europe with suitable conditions for T. callipaeda, and the Discussion says infestations are spreading across Europe. The Discussion also links the Portuguese cases to a predictive geoclimatic model. Our copy does not state that the model predicts an increase in reports over the next few years specifically in areas currently considered non-endemic. (LLM, conf=0.82)

“The occurrence of very high prevalence of thelaziosis by T. callipaeda in foxes (49.3%) as well as in other wild carnivore species (i.e., wolves, beech martens, brown hares, and wild cats) in some areas of southern Italy where canine thelaziosis is highly prevalent (i.e., about 60% of dogs) indicates the status of hyper-endemicity of eyeworm infestation in this area and the primary role foxes play”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
