According to WHO and OIE, “One Health” is an approach to designing and implementing programs, policies, legislation and research in which multiple sectors communicate and work together to achieve better health outcomes such as public health, animal health, plant health and environmental health. However, the concept of “One Health” is too often reduced to a (desirable) dialogue between physicians and veterinarians, with little or no involvement of specialists dealing with other fields such as wildlife ecology, ecosystem health and anthropological processes of pathogen transmission. Here, we explain why research on echinococcoses critically requires the expansion of the current collaborations, and to release significant funding in each field. If not, “One Health” will still stay as an aspiration, and will not hit its promised targets. The full version of this communication has been published as an opinion article in the first issue of the International Journal of Echinococcoses (Giraudoux, 2022). Giraudoux, P., 2022. One health and echinococcoses: something missing? International Journal of Echinococcoses 1, 15–18. https://doi.org/10.5455/IJE.2021.07.03.
