What is Infectious Arthritis?
Infectious arthritis is to have joint pain, inflammation (swelling), and stiffness caused by infection with bacteria, viruses or fungi.
These infections can enter the joint in several ways:
- after spread through the blood of a body part to another, eg from the lungs during pneumonia
- through a wound near
- after surgery, an injection or trauma, such as an insect bite
Once the infection reaches the joint, can cause symptoms of joint inflammation, and sometimes fever and chills. Depending on the type of infection, could be affected by one or more joints.
The joint most commonly affected by bacterial infection is the knee. Some joints, such as the fingers and toes are more prone to infection after a viral infection or direct injury as a bite. In intravenous drug users may be affected joints of the spine or the sternum. People who have had rheumatoid arthritis or other joint disease (joint disease) are more likely to develop infectious arthritis.
Certain bacteria can cause a form of infectious arthritis called reactive arthritis (formerly Reiter’s disease) which seems to be caused by the immune system reacts to the bacteria, not the infection itself. In reactive arthritis, joint inflammation develops weeks, months or even years after infection. Reactive arthritis occurs most commonly after infections in the gastrointestinal tract and genitals.
