The largest numbers of parvo cases have been identified in rural and remote areas of the country.
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.
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. Since its emergence, parvovirus remains a leading cause of enteritis (small intestine inflammation) in dogs, despite effective vaccines.
A University of Sydney study has found that canine parvovirus (CPV), a highly contagious and deadly disease that tragically kills puppies, is more prevalent than previously thought with 20,000 cases found in Australia each year, and nearly half of these cases result in death.
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.
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.
Puppies are at the greatest risk for parvo between the ages of 6 weeks to 6 months. Puppies can receive their parvo vaccinations at 6, 8 and 12 weeks of age. They must receive a full series of vaccinations to ensure complete immunity. Puppies require a parvo booster vaccine between 14 and 16 weeks of age.
Younger puppies are more susceptible to disease because the mother's immunity will protect them until around 10 weeks of age, but the vaccine series won't be complete until around 16 - 24 weeks if you follow your veterinarian's protocol.
Parvovirus can survive months on surfaces such as concrete so infections can still be transmitted to new dogs after your dog is recovered. This is especially important to consider when thinking about bringing another puppy into your home, either to add to your family or even if they are just visiting.
How Long Should I Wait Before Taking My Puppy Outside? Due to potential outdoor biohazards, most vets will advise that pet owners wait until a puppy is at least three months old before taking them outside.
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.
Certain breeds, including Rottweilers, Pit Bulls, Labrador Retrievers, Doberman Pinschers, German Shepherds, English Springer Spaniels, and Alaskan sled dogs, are particularly vulnerable to the disease.
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.
Parvo is a preventable disease, but even vaccinated dogs are not 100% protected from the virus.
Products that are effective at killing parvoviruses include Rescue™ (accelerated hydrogen peroxide), potassium peroxymonosulfate (e.g., Virkon® or Trifectant®), calcium hypochlorite (e.g., Wysiwash®), bleach, and sodium dichloroisocyanurate (e.g., Bruclean®).
The best way to prevent parvo is early vaccination. Puppies and younger dogs are most at risk. Symptoms include severe diarrhoea, severe vomiting, lethargy, fever and weakness. Puppies need to be kept isolated from unsafe areas where dogs congregate (such as parks or kennels) until they've completed their vaccinations.
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.
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).
Commonly called “parvo”, the organism is very stable in the environment, able to withstand freezing temperatures and many disinfectants to survive as long as seven months in a contaminated area.
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.
What causes parvovirus, how is it spread? Parvovirus is highly contagious, meaning that it spreads very quickly amongst animals who are not vaccinated against it. The virus itself is contracted by coming into direct contact with an infected canine, or indirectly, such as by sniffing an infected dogs feces.
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%.
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.
Do not let your puppies walk outside as the risk of parvovirus and leptospirosis with unvaccinated puppies is high.
