I am a veterinary technician and a certified animal control officer and I recently did a paper on proper disinfection of the parvovirus. You were correct in asking if flies could transmit the disease!! Parvovirus can be spread on hands, feet, clothing, tools, rodents and flies traveling from kennel to kennel! Dogs may carry the virus on their fur and feet even if they themselves do not get ill. The virus enters the dog through the nose or mouth and has an incubation period of 3 days to 2 weeks (usually 5-7 days). I have found also that the Parvovirus has a very distinct SMELL. The feces (usually bloody diarrhea) is what has the smell. Worms are definitely a possibility since 99% of puppies are born with roundworms and if left untreated can cause a ruptured bowel.
