Many of CDC’s activities use a One Health approach to better understand the links between human, animal, and environmental health. In addition to supporting One Health activities around the world, CDC is involved in One Health work in the United States.

U.S. One Health Zoonotic Disease Prioritization

CDC, the U.S. Department of Agriculture (USDA), and the U.S. Department of the Interior (DOI) organized a One Health Zoonotic Disease Prioritization (OHZDP) workshop in December 2017 to further joint efforts to address zoonotic disease challenges in the United States. Participants from each of these agencies prioritized eight zoonotic diseases of national concern for the United States that human, animal, and environmental health sectors responsible for federal zoonotic disease programs should jointly address using a One Health approach. This process represents a renewed commitment to improved coordination, collaboration, and communication between agencies and departments to use a multisectoral, One Health approach to address the priority zoonotic diseases.

Zoonoses Education Coalition

Pets are a wonderful part of our lives. Safe and responsible pet ownership is important to keep both people and pets healthy and happy. Some diseases, called zoonoses, can spread between people and animals. It is important for people with pets to know about zoonoses and how to prevent them so they can enjoy their pets without getting sick.

The Zoonoses Education Coalition (ZEC) is a group of partners that includes representatives from many different sectors, including the Pet Industry Joint Advisory Council (PIJAC), breeders and retailers, the National Association of State Public Health Veterinarians (NASPHV), the American Veterinary Medical Association (AVMA), the United States Department of Agriculture (USDA), the Food and Drug Administration (FDA), CDC, and others. This public-private partnership helps to exchange scientific information while promoting CDC’s zoonotic disease prevention messages to educate pet owners, public health officials, veterinarians, human healthcare providers, and other stakeholders on how to stay healthy while enjoying pets.

Messages on pets and zoonoses promoted by the ZEC include:

National Association of State Public Health Veterinarians

CDC works closely with the National Association of State Public Health Veterinarians (NASPHV). State public health veterinarians are the local and state professionals who regularly consult with physicians, emergency rooms, legislators, local officials, schools, health departments, and the general public on preventing and controlling diseases that people can get from animals and animal products. NASPHV, in partnership with CDC and others, collaborate on a variety of guidance and recommendationsexternal icon related to the prevention and control of zoonoses.

CDC Partnership on Influenza and Zoonoses Education among Youth in Agriculture

Since 2011, CDC has worked with the Council of State and Territorial Epidemiologists and the United States Department of Agriculture (USDA) to promote a One Health collaboration between federal and state public health and animal health authorities and state youth agriculture groups through a program called Influenza and Zoonoses Education Among Youth in Agricultureexternal icon. CDC initiated this program after the emergence of multiple outbreaks of human influenza illness caused by viruses that normally circulate in pigs. This innovative program educates youth about zoonotic diseases, delivers disease prevention messages, and strengthens One Health networks among state human and animal health departments and agricultural communities across rural America.

The program has a direct potential reach of 7.2 million youth through 4-H and Future Farmers of America (FFA) but can also influence their family, mentors, friends, agricultural producers, and others.

CDC scientists study how diseases in animals become threats to human health in the United States and around the world. They also look at how changes in the environment affect the health of animals and humans. Their research helps us understand:

  • How viruses, bacteria, and parasites spread between animals and humans.
  • How a person’s behavior can increase the risk that they will get sick from an animal.
  • How quickly these diseases can spread.

Collaboration and Partnerships

Across the United States, CDC works with local and state agencies as well as animal, environmental, and human health partners.
