Dr. Tested for Parvo virus. What is it and what are the symptons

My husband started swelling around his ankles and developed huge red spots. there is also swelling around his wrists. he is in a lot of pain in most all of his joints and the bottoms of his feet. he can barley walk. There was some talk of arthritis, but tests and x-rays have petty much ruled that out.

Here are the symptoms for Parvo Virus:

Arthralgia – The presence of pain in the bone joints, especially when these are moved.
Arthritis – The inflammation of the joints. The human parvovirus has made the joints swollen. Some children infected with the human parvovirus may also experience this symptom.
Hydrops – The abnormal accumulation of thin watery fluids in body tissues and body cavities.

Here is what Parvo Virus is:

The B19 virus, generally referred to as parvovirus B19[1] or sometimes erythrovirus B19[2], was the first (and until 2005 the only) known human virus in the family of parvoviruses, genus erythrovirus. B19 virus causes a childhood rash called fifth disease or erythema infectiosum which is commonly called slapped cheek syndrome.

Fifth disease or erythema infectiosum is only one of several expressions of Parvovirus B19. Any age may be affected, although it is most common in children aged six to ten years.

After being infected, patients usually develop the illness after an incubation period of four to fourteen days. The disease commences with fever and malaise while the virus is most abundant in the bloodstream, and patients are usually no longer infectious once the characteristic rash of this disease has appeared.

Teenagers or young adults tend to develop the so called 'Papular Purpuric Gloves and Socks Syndrome.' Unlike young children, these patients may be infectious with this rash.

The "slapped cheek" appearance typical of Fifths disease.The rash of fifth disease is typically described as "slapped cheeks," with erythema across the cheeks and sparing the nasolabial folds, forehead, and mouth. Because of this rash, fifth disease is sometimes called slapped cheek syndrome. Fifth disease is also known for "lace-like" rashes on the arms, legs, torso, and back. These rashes can last for up to 5 weeks and are worse after sun exposure, exercise, or hot baths.

If you need more information you can look it up online with the terms "Fifth Disease" or "Parvovirus B19", these are the two main terms used to identify this disease in humans.

I really hope this has helped you out at least a little.
Best Wishes!
