Parvoviruses are a family of small, non-enveloped DNA viruses that infect a wide range of animals. In humans, the best-known member is parvovirus B19, which can cause fifth disease and other illnesses. In dogs, canine parvovirus causes the disease commonly called parvo.

Classification and structure

Parvoviruses belong to the family Parvoviridae. They are very small viruses with a non-enveloped capsid and a single-stranded DNA genome. They infect vertebrate hosts and include both human and animal pathogens.

Human disease

The best-known human parvovirus is parvovirus B19, which is usually associated with mild illness such as flu-like symptoms, rash, and joint pain. It is the cause of fifth disease in children and can rarely lead to anemia or complications in pregnancy.

Canine parvovirus

Canine parvovirus, often called parvo, is a highly contagious viral disease of dogs. It commonly causes vomiting and diarrhea and can be fatal without treatment. Puppies and unvaccinated dogs are at highest risk.

Prevention and treatment

Vaccination is the main preventive measure for canine parvovirus, and veterinary sources describe it as highly effective. Human parvovirus B19 generally resolves on its own, while severe canine infections require supportive veterinary care.
