Can Dogs Transmit Parvovirus to Humans? Myths Debunked

There are many strains of parvovirus that affect different species. Canine parvovirus is a devastating disease in dogs that most often affects puppies who are too young to get the vaccine. This is not the same strain of parvovirus that affects humans. There is no example of parvovirus transmitting from dogs to humans and vice versa.

Parvovirus symptoms in dogs

The most common symptoms of parvo in dogs are vomiting and severe diarrhea that may contain blood or mucus. This can lead to extreme dehydration, intestinal damage, and septic shock. Other symptoms include abdominal pain, bloating, loss of appetite, lethargy, and either a fever or low body temperature.

Symptoms usually occur six to 10 days after the dog has come into contact with the virus. Puppies under 5 months of age typically have the most severe symptoms. Since they may not have finished the series of vaccines, they are also most susceptible to contracting the virus.

Death can occur quickly, often in just 48 to 72 hours. If your puppy has any symptoms of parvo, contact your veterinarian immediately, especially if he isn't yet vaccinated. Your vet will perform a fecal test to confirm the diagnosis.

Treatment options and outcome

Unfortunately, there is no treatment available to directly address the virus. However, with prompt and ongoing supportive care, there is up to a 90 percent survival rate for puppies with parvo. The first step in treating parvo is to administer fluids and electrolytes to counteract dehydration, and anti-spasmodic medication may be given to help control vomiting and diarrhea.

As the virus and diarrhea damage the intestinal lining, dogs are at increased risk of infection that can then enter the bloodstream, which is called septicemia. This is treated with antibiotics and anti-inflammatories. However, dogs and puppies with septicemia have a poor prognosis.
