About One Health

According to the Centers for Disease Control and Prevention, the One Health concept recognizes that the health of humans is connected to the health of animals and the environment.

There are many examples that show how the health of people is related to the health of animals and the environment. For instance, animals can pass some diseases on to humans. These diseases are known as zoonotic diseases. Examples include:

  • Rabies
  • Salmonella infection
  • West Nile virus fever

Animals also share our susceptibility to some diseases and environmental hazards. Because of this, they can serve as early warning signs of potential human illness. For example, birds often die of West Nile virus before humans get sick with West Nile virus fever.

One Health is not a new concept, but it has become more important in recent years because many factors have changed the interactions among humans, animals, and the environment. These changes have caused the emergence and reemergence of many diseases.
