Zoonosis/Disease Prevention
Welcome to the Zoonosis page!

A zoonotic disease is any infectious disease that is transmitted from animals to humans.

The Zoonosis program is a part of the Veterinary Public Health division and we are here to serve the Harris County community.

For questions or information regarding zoonotic diseases, please contact us at 281.999.3191.

Zoonotic Diseases

Veterinarians are an important source of information for zoonotic diseases.  If a veterinarian suspects a zoonotic disease, it is their responsibility to alert the owner of the potential for the disease to spread to humans.  

Some humans are more at risk than others:  

  • Infants and small children
  • Pregnant women
  • Elderly
  • Anyone with a weakened immune system 
  • Veterinarians
  • Veterinary support staff and other animal health care workers
  • Campers, hikers and others who spend a lot of time outdoors  

There are several publications, including newsletters, Rabies maps, Rabies Post-Exposure Guide for Animals and Jurisdiction map that may prove to be useful.  Visit our Newsroom page.
