The department's Zoonotic and Vector-borne Disease Program works with partners using a One Health perspective to prevent and control zoonotic and vector-borne disease.
Zoonotic and vector-borne diseases are caused by pathogens that spread from animals and arthropods (such as mosquitos and ticks) to people. Lowering the risk to our health depends on:
- Understanding environmental conditions and how they impact animals, arthropods and the pathogens they carry
- Understanding the distribution of vector and wildlife populations
- Understanding where these pathogens exist in our state
Climate changes affect each of these factors, so ongoing disease monitoring is necessary.
What We Do
The Zoonotic and Vector-borne Disease program works to lower disease risk and respond to public health events involving zoonotic, vector-borne, or environmental pathogens. We partner with federal, tribal, state, and local health departments. Our program:
- Monitors amounts of zoonotic and vector-borne diseases in Washington
- Reports location and amounts of zoonotic and vector-borne disease
- Emphasizes the connections of human, animal, and environmental health, and uses data to improve One Health
- Prevent disease through public health efforts and education
- Collaborates with One Health colleagues to improve the health of people, animals, and our shared environments
- Prepares for and responds to outbreaks and public health emergencies
- Animal Transmitted Diseases - Zoonotic disease topics like rabies, hantavirus, West Nile virus, and tick-borne diseases.
- Pests - Controlling pests such as rodents, bed bugs, mosquitoes, and ticks.
- Zoonotic Disease Rules and Guidelines - Rabies vaccination requirement for pets, animal vendor and venue operator requirements, and other rules and guidelines.
- Zoonotic Disease Data and Reports - West Nile virus, plague, and reports.
- Veterinarian Resources - Resources to help veterinarians to control zoonotic diseases.
- Washington Tracking Network - Zoonotic Disease - Data showing the amount of zoonotic disease, such as West Nile virus in our state.
- Notifiable condition reporting forms and guidelines
