Canine parvovirus
Canine parvovirus type 2 (CPV2, colloquially parvo) is a contagious virus mainly affecting dogs, and thought to originate in cats. The current belief is that the feline panleukopenia mutated into CPV2. Parvo is highly contagious and is spread from dog to dog by direct or indirect contact with their faeces. Vaccines can prevent this infection, but mortality can reach 91% in untreated cases. Treatment often involves veterinary hospitalization. Canine parvovirus may infect other mammals; however, it will not infect humans.
