How long does it take for a dog to get parvoviral enteritis?

Clinical signs of parvoviral enteritis generally develop within 5–7 days of infection but can range from 2–14 days. Initial clinical signs may be nonspecific (eg, lethargy, anorexia, fever) with progression to vomiting and hemorrhagic small-bowel diarrhea within 24–48 hours. Approximately 25% of dogs may have nonhemorrhagic diarrhea. Physical examination findings can include depression, fever, dehydration, and intestinal loops that are dilated and fluid filled. Abdominal pain warrants further investigation to exclude the potential complication of intussusception. Severely affected animals may present collapsed with prolonged capillary refill time, poor pulse quality, tachycardia, and hypothermia—signs potentially consistent with septic shock. Although CPV-associated leukoencephalomalacia has been reported, CNS signs are more commonly attributable to hypoglycemia, sepsis, or acid-base and electrolyte abnormalities.

What disinfectant kills parvovirus?

Parvoviruses are very durable, can persist in the environment for years, and are resistant to inactivation by quaternary ammonium disinfectants, including Roccal, Parvosol, Triple Two, Broadcide, and A33. Only 4 disinfectants reliably kill parvoviruses – sodium hypochlorite (bleach), calcium hypochlorite (WysiWash), potassium peroxymonosulfate (Trifectant), and accelerated hydrogen peroxide (Accel/Rescue). For optimum killing activity, environmental surfaces contaminated with feces, urine, vomit, blood, and other organic material must first be cleaned with a detergent before applying the disinfectant solution and allowing contact with the surfaces for at least 10 minutes before rinsing.

Why are cats at risk for parvovirus?

Kittens and puppies are the most susceptible to parvoviral infection due to lack of protective immunity from maternally derived antibodies or from ineffective responses to vaccination. They typically enter shelters at an age when maternal immunity has waned to a level that does not protect against infection, but still interferes with responses to vaccination. Unvaccinated young adult cats and dogs are also at risk for infection, but the clinical disease may be inapparent or mild. Older cats and dogs that have spent time outdoors eventually develop immunity by natural exposure to virus in the environment. Panleukopenia outbreaks commonly occur in the summer and fall (“kitten season”) when large numbers of kittens are admitted to shelters. Since dogs are not seasonal breeders like cats, there is no apparent seasonal pattern to parvovirus outbreaks in dogs.

How long should you quarantine an animal?

Since sick animals shed infectious virus for 3-4 days before onset of clinical disease, all others exposed to the sick animals either by direct contact or fomite contact should be quarantined for 14 days (maximum incubation period). The infection status of exposed animals is unknown – they may be infected and in the pre-clinical incubation period, have subclinical infection with shedding, or not infected due to immunity. Quarantined animals should be monitored twice daily for clinical signs. If clinical signs occur, the animal should be moved to isolation to help reduce the infectious dose of virus in the environment. The 14-day quarantine clock must be re-started for the remaining animals.

A relatively quick and inexpensive test can be performed by looking for the virus in the feces or a swab of the rectum. Your veterinarian will likely also recommend blood work. Some dogs may be anemic from blood loss in the intestines, or have very low blood sugar levels from t…

Treatment

  • IV fluids and management of electrolytes are the cornerstone of treatment for parvo. Antibiotics are given to prevent secondary infections, along with medications to help relieve vomiting, nausea and pain. De-wormer should be given since many puppies also have intestinal parasites that can worsen diarrhea. If the sugar levels are low, IV supplementation will be required. Nutrition is a ve…

Outcome

  • Survival from a parvovirus infection is possible, but depends on age, size and how sick the dog is when owners first seek care. Most patients will not survive without treatment. Starting medical treatments when illness first sets in will increase the likelihood of recovery.
