U.S. Centers for Disease Control and Prevention (CDC) – November 2016

What you need to know about CDC & One Health


In today’s connected world, a coordinated public health approach is needed to protect both people and animals from diseases. One Health is this coordinated approach, as it recognizes that the health of people is connected to the health of animals and our environment.

A One Health approach is needed to better understand certain diseases, such as rabies, Salmonella, West Nile virus fever, Q fever, and other zoonotic diseases that are spread between people and animals.

Here are a few things you need to know about CDC and One Health:

  • One Health affects all of us—6 in 10 infectious diseases in people are spread from animals.
  • One Health is a global approach—infectious disease threats are everywhere, and diseases know no borders.
  • One Health includes our furry friends—it is important for people to know how to enjoy their pets and other animals without getting sick from diseases that animals can carry or from the foods they eat.

CDC uses a One Health approach by working with physicians, veterinarians, ecologists, and many others to monitor and control public health threats as well as learn more about how diseases are spread between people, animals, and the environment.
