What are the effects of Parvo in humans?
Parvo is a virus that can produce pain, rashes, and itching in humans. It generally effects the immune system, and commonly will go away on its own. However, some people who already have immune system problems do develop severe infections with fevers and anemia, but this is rare. Treatment for Parvo is usually to help the symptoms only, as there is no cure.
Your son in law may have this virus, but it will probably go away in a month or so, and not cause him any other health problems. I do not think his high blood pressure had anything to do with him getting this virus. The virus is actually quite common, especially in children. It is spread from person to person (not from dogs), as we get infected with a different strain than animals. Fortunately for humans, it is not as serious as the strain dogs get.
1 1/2 yrs ago I was diagnosed with Parvo virus B-19. My immune systerm was already weakened following open heart surgery and I developed the rare arthritic version of it. I had severe swelling and joint pain in my hands, face and knees, and my face got very red from the rash. My doctor treated me with a combination of steroids and painkillers and the symptoms got better. Within six months I was a lot better. My doctor said it's common in children and is usually mistaken for the common cold. I have had a couple of flareups since, they usually cause some joint pain and inflammation and last 1-2 weeks.
