One World - One Health™

In September 2004, WCS convened health experts from around the world to discuss the movements of diseases among human, domestic animal, and wildlife populations. Held at Rockefeller University in New York City, the symposium set priorities for an international, interdisciplinary strategy for combating threats to the health of life on Earth.
In today’s globalized world, no one sector of society or single professional discipline has enough knowledge and resources to prevent the emergence or resurgence of diseases. No one nation can reverse the patterns of habitat loss and extinction that undermine the health of all the world’s people and animals. Only by breaking down the barriers between agencies, individuals, specialties, and sectors can we ally our collective expertise and spark the innovation needed to anticipate and combat serious challenges to the health of people, domestic animals, and wildlife and to the integrity of ecosystems. We cannot solving today’s threats and tomorrow’s problems with yesterday’s approaches. Instead we must devise adaptive, forward-looking, and multidisciplinary solutions to the challenges that lie ahead.
To urge world leaders, civil society, the global health community, and institutions of science to holistically approach the prevention of epidemic/epizootic disease and the maintenance of ecosystem integrity by:
- Recognizing the link between human, domestic animal, and wildlife health, and the threat disease poses to people, their food supplies and economies, and the biodiversity essential to maintaining the healthy environments and functioning ecosystems we all require.
- Recognizing that decisions regarding land and water use have real implications for health. Alterations in the resilience of ecosystems and shifts in patterns of disease emergence and spread manifest themselves when we fail to recognize this relationship.
- Including wildlife health science as an essential component of global disease prevention, surveillance, monitoring, control, and mitigation.
- Recognizing that human health programs can greatly contribute to conservation efforts.
- Devising adaptive, holistic, and forward-looking approaches to the prevention, surveillance, monitoring, control, and mitigation of emerging and resurging diseases that fully account for the complex interconnections among species.
- Seeking opportunities to fully integrate biodiversity conservation perspectives and human needs (including those related to domestic animal health) when developing solutions to infectious disease threats.
- Reducing demand for and better regulating the international live wildlife and bushmeat trade, not only to protect wildlife populations but to lessen the risks of disease movement, cross-species transmission, and the development of novel pathogen-host relationships. The costs of this worldwide trade in terms of impacts on public health, agriculture, and conservation are enormous, and the global community must address this trade as the real threat it is to global socioeconomic security.
- Restricting the mass culling of free-ranging wildlife species for disease control to situations where there is a multidisciplinary, international scientific consensus that a wildlife population poses an urgent, significant threat to human health, food security, or wildlife health more broadly.
- Increasing investment in the global human and animal health infrastructure commensurate with the serious nature of emerging and resurging disease threats to people, domestic animals and wildlife. Enhanced capacity for global human and animal health surveillance and for clear, timely information-sharing (that takes language barriers into account) can only help improve coordination of responses among governmental and nongovernmental agencies, public and animal health institutions, vaccine / pharmaceutical manufacturers, and other stakeholders.
- Forming collaborative relationships among governments, local people, and the private and public (i.e. non-profit) sectors to meet the challenges of global health and biodiversity conservation.
- Providing adequate resources and support for global wildlife health surveillance networks that exchange disease information with the public health and agricultural animal health communities as part of early warning systems for the emergence and resurgence of disease threats.
- Investing in educating and raising awareness among the world’s people and in influencing the policy process to increase recognition that we must better understand the relationships between health and ecosystem integrity to succeed in improving prospects for a healthier planet.
What WCS is Doing
The One World – One Health effort has held workshops in India, China, and Brazil, promoting its 12 “Manhattan Principles”. At the IUCN 2003 World Parks Congress in Durban, South Africa, WCS launched the AHEAD (Animal Health for the Environment And Development) initiative, which focuses on some thorny issues between conservation and development, such as overgrazing, water resources, and food security.
In Brazil, WCS currently manages funding for research that exemplifies the One World – One Health concept. Such projects include:
- Studying the ecological interrelations between capybaras—the world’s largest rodent—and ectoparasites, in regard to possible transmission of Brazilian spotted fever and other rickettsial diseases to humans. (Kátia Torres)
- Evaluating whether parasite transmission between domestic and wild carnivores threatens people living in the Pantanal region. (Fabiana Rocha)
- Assessing and promoting environmental health in traditional fishing communities in the coast of the state of Paraná. (Paulo Rogério Mangini)
- Monitoring for avian influenza and Newcastle disease viruses in the Brazilian Amazon region. (Luiz Durigon)
- Tracking migratory birds to understand their interactions with other wild birds and domestic poultry, with a focus on the prevention of avian influenza. (Virginia Petry)

From the Newsroom
WCS veterinarians working in Brazil evaluate whether forest fragmentation and other land-use changes make wildlife, as well as livestock, more susceptible to infectious diseases.
At our country's doorstep, WCS health experts are helping authorities investigate the smuggling of wildlife and its stowaway diseases.
