Guided by the theme “Advancing Infectious Disease Prevention and One Health through Collaboration,” the 11th Edition of World Congress on Infectious Diseases & One Health (WCID 2027) will take place from October 21–23, 2027, in Orlando, Florida, USA, with Online participation available to attendees worldwide. Recognizing that the health of people, animals, and the environment is closely connected, the congress offers an international platform for advancing the prevention, detection, and control of infectious diseases through a One Health approach.

WCID 2027 brings together infectious disease physicians, microbiologists, virologists, epidemiologists, veterinarians, environmental health scientists, public health officials, infection control practitioners, clinical researchers, academicians, students, and pharmaceutical and diagnostic industry professionals. By connecting human, animal, and environmental health expertise, the congress encourages the interdisciplinary partnerships that effective disease control requires.

The scientific program will cover emerging and re-emerging infections, zoonotic and vector-borne diseases, antimicrobial resistance and stewardship, viral, bacterial, fungal, and parasitic infections, healthcare-associated infections, outbreak investigation and surveillance, food safety and foodborne pathogens, environmental and wastewater surveillance, tropical and neglected diseases, molecular diagnostics, global health security, and One Health policy and implementation.

Attendees will benefit from keynote lectures, plenary sessions, oral and poster presentations, panel discussions, young researcher forums, exhibitions, and networking opportunities. We look forward to welcoming you to Orlando, Florida, USA, or Online to exchange knowledge and strengthen collaborative responses to infectious disease threats worldwide.
