The American Public Health Association (APHA) 2019 annual meeting will be held from 2-6 November, 2019 in Philadelphia, PA, USA. APHA's Annual Meeting and Expo is the largest and most influential annual gathering of public health professionals. APHA's Annual Meeting and Expo 2019 is where public health professionals convene, learn, network and engage with peers. With the Annual Meeting, we strengthen the profession of public health, share the latest research and information, promote best practices and advocate for public health issues and policies grounded in research. This year's theme is "Creating the Healthiest Nation: For science. For action. For health." In this meeting nearly 13,000 attendees join us each year to present, learn and find inspiration.
