The International Society for Infectious Diseases (ISID) is dedicated to developing partnerships through advocacy, education, and delivering solutions to the problems of infectious diseases around the globe. For decades, the ISID encourages collaborative efforts between human, veterinary, and environmental health communities to best detect, manage, and prevent infectious disease spread. The ISID has a particular focus on resource limited countries that disproportionately bear the burden of infectious diseases. The ISID is the premier organization convening yearly international conferences on cutting-edge science and community in the field of infectious diseases within a One Health context.
