How do you get swollen joints from infectious arthritis?

ANSWER

Infectious arthritis (a.k.a septic arthritis) is the result of a bacterial, viral, or fungal infection in the tissues and fluid of a joint. Joint infection usually occurs after a previous infection in the body. The infection travels to the joint via the bloodstream from another part of the body, such as a person's skin, nose, throat, ears, or an existing wound. Within hours to days, pain, inflammation, swollen joints, and fever develop. The joints most commonly affected by infectious arthritis are the knee, hip, shoulder, ankle, and wrists. Damaged joints are more vulnerable to infection.

Common bacterial causes of infectious arthritis include Neisseria gonorrhoeae and Staphylococcus aureus. Some joint infections may be caused by more than one organism.
