Zoonoses (also called zoonotic diseases) are diseases that are naturally transmitted between animals and humans. Some examples of zoonoses are rabies, avian influenza, and salmonellosis. Vector-borne diseases are those diseases that require a vector, such as a mosquito or tick, for transmission. Lyme disease and West Nile virus are examples of vector-borne diseases.​

The Center for Zoonotic and Vector-​​borne Diseases (CZVBD) works to reduce the incidence and impact of rabies and other zoonotic and vector-borne diseases in Maryland. We do this in partnership with Maryland’s 24 local health departments, other State agencies, health care providers, veterinarians, and the general public.
