Do you think this man has Parvo virus?

Just doing a little research on the Mayo Clinic site yes, it looks like there is a human form of it. It shows up in children with a red rash, fever and stomach upset and presents mainly in adults as joint pain in the wrists or ankles lasting for weeks. A blood test determines it. It looks like the doctor could be right.

No, but I knew someone with Bartonella. The problem is that Bartonella is not recognized by the CDC in the US as a disease that humans get. Only dogs and cats are supposed to get it. Therefore it was never diagnosed as such, even though she did test positive for it in Europe. She even had photographic proof of the microbes they had isolated in her blood. Because she lived in the USA he never was treated for it, or properly diagnosed with any other disease. “Golly lady, you’re sick! Sorry we can’t help you! Next!”

This is what the CDC has to say about parvovirus: Parvovirus B19 infects only humans. You can have a range of symptoms depending on your age and overall health. About 2 out of 10 people who get infected with this virus will not have any symptoms. Others may have only mild, cold-like illness…

Pet dogs and cats can get infected with other parvoviruses that do not infect humans. Pets can be vaccinated to protect them from parvovirus infection.

Parvo ,in animals, is most likely contracted when the immune system is suppressed, or compromised. Puppies under 1 year old, and older dogs…

Never heard of it in humans, but the symptoms listed are vastly different from animal symptoms. Animals present with vomiting,diarrhea, and severe lethargy. Not the swelling mentioned.
