Infection with parvovirus occurs when a puppy is exposed to contaminated feces or to an object, such as shoes or a sidewalk, which has been contaminated by feces. The virus can live on contaminated surfaces or clothing for up to 5-6 months. Parvovirus becomes widespread throughout the body in 3-4 days.
Outside of your dog, the virus can survive indoors for at least one month, and outdoors it can survive for many months and even a year under the right conditions. Use a cleaner proven to kill parvovirus. Talk to your vet about the best way to remove the parvovirus from your home environment or kennels.
The best household cleaner to use to kill parvovirus is bleach (1 part bleach to 30 parts water). It should be used on hard surfaces including tiles, concrete, paving bottoms of shoes etc – leave the bleach on the surface at least 10-15 minutes. Anything that can be washed in bleach should be.
Extremely resilient, parvovirus can survive in the environment for up to nine years, including the ground and soil. It can also withstand most household cleaning products (bleach is an exception), heat, cold and humidity, all of which makes the spread of the virus is hard to control.
The best and most effective disinfectant against viruses (including parvoviruses) is BLEACH. One part bleach is mixed with 30 parts water and is applied to bowls, floors, surfaces, toys, bedding, and anything contaminated that is colorfast or for which color changes are not important.
Washing hands thoroughly with soap and water will remove the virus. Specific disinfectants need to be used to remove parvovirus from the environment, including toys, clothing and cages. See the Resources section below for a list of disinfectants effective against parvovirus – note it is a “nonenveloped virus.”
In regards to your first question, parvovirus is pretty hardy virus, as I am sure you are aware. There are some studies stating that it can be inactivated readily at boiling temperatures (212 degrees F); unfortunately this isn't an option in conventional washing machines.
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.
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.
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.
Parvovirus is a scary disease that typically affects unvaccinated puppies. It is highly contagious, so if your dog is diagnosed with this virus, you'll want to thoroughly disinfect your home before it returns.
Begin with using straight hot water and steam clean the entire carpet. This will lift the stain off the surface. After you have completed the first surface washing, focus next on removing the stains. Use either a commercial pet stain remover or you can use a mixture of hydrogen peroxide and baking soda.
If a puppy is exposed to canine parvovirus during this gap in protection, it may become ill. An additional concern is that immunity provided by a mother's milk may interfere with an effective response to vaccination. This means even vaccinated puppies may occasionally be infected by parvovirus and develop disease.
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).
The disease is so infectious that even a human that has unknowingly been in contact with an infected dog can spread the virus to puppies and other dogs just by touching them. Which means that an innocent pat on the head can become the beginning of a life-threatening condition.
The parvovirus is not airborne, but nearly all surfaces can carry it, including human skin. After an individual has been exposed to the disease, an infestation can occur on the ground, on surfaces in kennels, on their hands, and on their clothing. A dog can also carry contaminated fecal material on its fur or paws.
Even if your veterinarian does everything right, there is still a chance that your puppy won't survive parvo. The near-death signs of parvo include severe lethargy, continuous bloody diarrhea, anorexia, and bloody vomiting. You may not want to admit it to yourself, but this is the point of no return.
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.
What are the first signs of parvo in a dog? Initial signs that your dog may have contracted parvo are running a fever, lethargy, lack of appetite, and anorexia. These initial signs may progress and can result in vomiting and diarrhea within two days after showing their first symptom.
– 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.
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.
While parvo is not a risk to humans, it is very contagious to other dogs. Although bathing will not prevent your dog from being contagious, it will reduce the amount of contagion and clean soiled fur of body fluids.
Spray the areas of your lawn frequented by your dog. Use a mixture of one part bleach to two parts water. Don't allow your dog into this part of your yard until the grass dries out. If your dog has a dog house or toys outdoors, wipe down the dog house and throw away the toys.
Can a dog get parvo twice? Once a dog has recovered from parvo, it is unlikely that they will contract the virus again. The immunity from the virus lasts for several years, protecting your dog from reinfection. It is theoretically possible for a dog to get parvo twice, but such chances are very slim.
