– Parvovirus, the highly contagious, and potentially deadly, virus which attacks the dog's gastrointestinal tract, has the highest prevalence in New Mexico, Texas, Nevada, Arizona and Mississippi.
A 2017 study estimated national incidence to be 4.12 cases per 1000 dogs, and an annual case load of 20,110 based on 4219 CPV case reports in a survey of all Australian veterinary clinics, with a 23.5% response rate.
The virus affects dogs' gastrointestinal tracts and is spread by direct dog-to-dog contact and contact with contaminated feces (stool), environments, or people. The virus can also contaminate kennel surfaces, food and water bowls, collars and leashes, and the hands and clothing of people who handle infected dogs.
Parvo can be found in almost any environment. It is transmitted when a susceptible dog comes in contact with the virus. This includes contact with the feces of an infected dog, or objects that contain the virus (shoes, clothes, bedding, bowls, grass, carpets, floors, etc).
It's a virus that was non-existent prior to the 1980s. Now, for most dog owners in Australia, parvovirus is a disease that is part of their pet's regular vaccination regime.
Puppies are vaccinated against parvo at approximately 6, 8, and 12 weeks of age. They are vulnerable to the disease until they have received all three shots in their vaccination series, which means owners need to take extra precaution during this time to prevent their puppies from contracting the virus.
How does it spread? Parvovirus is highly contagious and can stay on surfaces and in environments for a long period of time—withstanding heat, cold and humidity. Dogs can contract the virus by interacting with infected dogs, or by coming into contact with contaminated faeces, surfaces or environments.
Canine parvovirus type 2 (CPV-2) is highly resistant and can survive for months in the environment. Studies have observed that if your Fido is not vaccinated, the chances of him getting parvovirus are very high, and the morbidity rate is 100%.
Parvo is a preventable disease, but even vaccinated dogs are not 100% protected from the virus.
In the U.S., people tend to get infected with parvovirus B19 more often in late winter, spring, and early summer. Mini-outbreaks of parvovirus B19 infection occur about every 3 to 4 years. Since parvovirus B19 only infects humans, a person cannot get the virus from a dog or cat.
Certain breeds and types of dogs appear to have a higher risk of parvovirus infection or show more severe illness once infected. These include Rottweilers, Doberman Pinschers, Labrador Retrievers, German Shepherds, Bull Terrier breeds, and Alaskan sled dogs.
Even if your puppy is vaccinated, and has created antibodies to fight off the infection, she can still become infected with the virus. If you live in a high-risk area or have met a Parvovirus-infected dog, your puppy can pick up a large amount of virus material from this interaction.
High heat will kill parvovirus but it has to be temperatures of around 120-130 degrees Celsius for a period of 15 minutes. Sunlight can also deactivate the virus.
Once a puppy has symptoms of parvo, if left untreated they can die within 48 - 72 hours. It can be simply diagnosed and survival is possible if treated soon enough. If left untreated the mortality rate is as high as 91%.
Financial hardships caused by the pandemic have also prevented many pet owners from keeping up with their companions' vaccine protocol. While life has, in many ways, gone back to normal since the early days of the pandemic, parvo cases remain on the rise in many areas.
Canine parvovirus can be found in almost any environment, but not every dog who comes into contact with the virus becomes infected. Several factors come into play in infection, including the immune status of the dog and the number of viruses the dog is exposed to.
The first sign of parvo for puppies is often lethargy, lack of appetite, and a fever. Canines will begin to suffer from vomiting and diarrhea as the virus progresses, and can experience dehydration and a high heart rate as a result.
Can vaccinated dogs get parvo? Short answer: YES! Some may think once their dog is vaccinated they can't catch Parvo, but the virus has different strains and reinvents itself. So unfortunately, dogs definitely can still catch the parvovirus.
If possible, flush the yard with water and allow to dry. Then apply a disinfectant that is effective with organic material, such as AHP or potassium peroxymonosulfate. These can be used with a pesticide sprayer or hose-end sprayer at the proper dilution to saturate the outside area.
Parvo can live on concrete for up to nine years. It's a highly contagious virus that can survive on surfaces, making it important to disinfect any areas that may have come into contact with the virus.
#1: All dogs are at risk
Parvovirus can infect any dog, but is most common in unvaccinated or incompletely vaccinated puppies from 6 weeks to 6 months old.
Despite there being an effective vaccine for the illness, parvo remains fairly common, Dr.
The highest risk of death occurs around 24-72 hours after you see the symptoms of parvo in dogs. If a puppy is hospitalized, given lots of supportive care, and monitored closely, the survival rate is usually around 75-80%.
Parvo can live in the ground, the grass, on bushes – pretty much anywhere (although it is not an airborne virus). Disease prevention is always less costly (and risky) than treating a condition your pet has developed.
Symptoms of Parvo
Symptoms of intestinal parvo begin to show from three to 10 days after the infection.
