The modeller community in animal health needs to share good modelling practices, develop new methods to face current modelling challenges, work on solutions for simpler and better data access, facilitate model comparison and ensemble modelling, and enhance interactions with end-users and stakeholders. To that end, we propose to federate the scientific community working on epidemiological modelling in animal health in a new international network: the ModAH-HUB. We propose to start with concrete priority actions built upon existing projects, giving progressively room to new ideas and actions. Working groups will concern transversal topics as well as case studies on specific diseases or groups of diseases. To ease model storage, sharing, search and reuse, we also propose to build an extensive and open inventory of animal health models: the ModAH-collection. This talk is a unique occasion to discuss together of this initiative, which aims to be as open and representative of the community as possible.
