Historic paintings, and ancient remains from 2000 B.C, show evidence of rheumatoid arthritis. Historically, soldiers given an anti-parasitic drug for malaria reported improvement in arthritis symptoms; and Dr. Blount suggested a parasite caused rheumatoid arthritis. Chlamydia trachoma, psittacosis and pneumonia have been isolated from arthritic joints. Dr. Gerard reported ocular trachoma was more likely to cause arthritis than sexually acquired trachoma. Feline mycoplasma causes arthritis in cats, and can be transmitted from cat to humans, dogs and farm animals. Dr. Storz reported chlamydia pecorum caused polyarthritis in cows, dogs, and pigs, and can be transmitted from animals-to-humans.

Arthritis is inflammation in the joints, muscles, and connective tissue; and includes symptoms of pain, heat, stiffness, swelling, degeneration, and physical changes in joints. Arthritis includes degenerative arthritis (osteoarthritis, degenerative arthritis, traumatic arthritis, and overuse arthritis); and autoimmune arthritis, which are systemic diseases that involve inflammation generated by the immune system (reactive arthritis, rheumatoid arthritis, psoriatic arthritis, polyanginitis, spondyloarthritis, septic arthritis, gouty arthritis, lupus, and fibromyalgia). Autoimmune arthritis can be caused by direct infection of the joint; or by an immune system attack on the pathogens, the abnormal proteins, and debris generated by the pathogens. The root cause of autoimmune arthritis is immortal pathogens.
