Infectious arthritis

[Vania]

Infectious arthritis is infection in the fluid and tissues of a joint usually caused by bacteria but occasionally by viruses or fungi.

Bacteria, viruses, or fungi may spread through the bloodstream or from a nearby infection into a joint, causing infection.
Pain, swelling, and fever usually develop within hours or a couple of days.
Joint fluid is withdrawn with a needle and tested.
Antibiotics are begun immediately.

There are two types of infectious arthritis:

Acute
Chronic
