The American Public Health Association is the oldest and most diverse organization of public health professionals in the world and has been working to improve public health since 1872. The Association aims to protect all Americans, their families and their communities from preventable, serious health threats and strives to assure community-based health promotion and disease prevention activities and preventive health services are universally accessible in the United States. APHA represents a broad array of health professionals and others who care about their own health and the health of their communities. APHA builds a collective voice for public health, working to ensure access to health care, protect funding for core public health services and eliminate health disparities, among a myriad of other issues. Through its two flagship publications, the peer-reviewed American Journal of Public Health and the award-winning newspaper The Nation’s Health, along with its e-newsletter Inside Public Health, the Association communicates the latest public health science and practice to members, opinion leaders and the public.
