Veterinarians care for the health of pets, livestock, and animals in zoos, aquaria, racetracks, laboratories and more. That work ultimately affects the health of human beings both directly and indirectly.
Veterinarians use their skills to protect against zoonotic diseases that can spread from animals to people. They also conduct clinical research on diabetes, arthritis, cancer and other health problems that affect humans and animals. Others work in basic research, broadening our knowledge of animals and medical science, and in applied research, developing new ways to use existing scientific knowledge to improve animal and human health.
