Reactive arthritis refers to general joint inflammation - often caused by virus or bacteria infection. The inflammation may affect the joints, urethra, skin or eyes.
Many infections can lead to reactive arthritis. The common infections include: glandular fever, streptococcal throat infection, viral flu or food poisoning. The infection often starts elsewhere in the body, but not in the body joints. Then the infection leads to joint inflammation and reactive arthritis.
Reactive arthritis mostly affects adult men, aged from 20 to 40. The common symptoms include: joint swelling, mild fever, temporary discomfort, eye or skin infection.
