Parvovirus in Dogs - Case Definition

This case definition is used to evaluate and categorize cases of parvovirus reported in dogs to the Los Angeles County Department of Public Health. It was developed by public health veterinarian by reviewing published published literature and reported cases of parvovirus in LA County dogs. Earlier case reports of this disease were reviewed and a few reclassified to meet this 2015 case definition.

  RATIONALE FOR SURVEILLANCE IN ANIMALS   Canine parvovirus is not zoonotic. However, people in areas with a greater amount of parvo in dogs may also face elevated risk for exposure to zoonotic diseases because of the lack of veterinary care. Effective vaccination against canine parvovirus has been a standard part of veterinary preventative care for decades. Therefore, cases serve as a general marker for areas in Los Angeles County where residents have lower access to, or utilization of, basic veterinary care. Veterinary care includes a package of preventative services, treatments and education for pet owners that help prevent zoonotic infections of many types.  Epidemiologic data on parvo in dogs indicates areas where the need for clinical and educational animal health services is higher.
