HOUSTON, TX – Harris County Public Health (HCPH) is responding to an outbreak of canine parvovirus at its Veterinary Public Health—Harris County Pets (VPH) shelter. To control the spread of this highly contagious virus, several areas within the shelter are under quarantine, and enhanced sanitation protocols are in place to keep the animals in our care safe. To further mitigate the spread of the virus, VPH will be closing owner surrenders through Sunday, May 18.
Public interaction with dogs inside the shelter will be limited, and we are canceling our volunteer dog walking activities further notice. Public interaction will remain in effect and reassessed on a 48-hour basis.
What is Parvovirus?
Canine parvovirus is a potentially deadly virus that attacks the stomach and intestines of dogs. It is particularly dangerous to young, unvaccinated puppies and dogs with weak immune systems, but any dog can become infected. The virus is found in the feces, vomit, and other bodily fluids of infected dogs and can survive in the environment for weeks to months. It can be spread through contaminated objects like bedding, toys, clothing, and even shoes.
Clinical signs of parvovirus include:
- Vomiting and diarrhea (often with blood)
- Lethargy
- Decreased appetite
- Abdominal pain
- Fever
- Weakness
While there is no cure for canine parvovirus, supportive treatment is critical. Treatment depends on the severity of the disease and can be extensive, often requiring veterinary hospitalization. Diagnosis is based on clinical signs, testing, and a veterinary exam. Parvovirus outbreaks are a common challenge in animal shelters due to the high-density environment and frequent intake of unvaccinated dogs. Shelters work swiftly to contain the spread through immediate isolation, enhanced sanitation protocols, and vaccination efforts.
Vaccination is the most effective way to prevent parvovirus. HCPH urges pet owners to verify their pets are up to date on vaccinations before introducing a new animal into the home. New adopters must complete the full vaccination series with their veterinarian to ensure their pets are protected. If a dog needs a parvovirus vaccine, it can be administered by a veterinarian or at the Harris County Pets Wellness Clinic. To schedule an appointment, community members can call 281-999-3191.
