Animal Diseases

The health of animals—pets, farm animals, and wildlife—is linked to the health of humans who share their environment. A small number of the communicable diseases that animals can be infected with are transmissible (under certain circumstances) to people. Contra Costa Public Health monitors the occurrence of several animal diseases with significant human health implications.

WE RELY ON VETERINARIANS and the public to notify us when they encounter certain diseases or conditions in animals. Reporting this information helps Contra Costa Public Health protect the public from illness.
