Please stay alert for new resources published on this page by the ACAP intersessional group. As new information becomes available and our guidelines are updated, further communication from diverse perspectives will be essential. These initiatives are crucial to preventing the human-mediated spread of HPAI viruses to ACAP species, enhancing surveillance measures, and accurately assessing impacts on ACAP species.
