What term refers to arthritis caused by an infection spreading from another part of the body?

• A. Infectious arthritis
• B. Autoimmune arthritis
• C. Open fracture
• D. Hernia

Answer: (A)

Infectious arthritis is when an infection from somewhere else in the body spreads to a joint, causing arthritis. This can happen as bacteria, viruses, or fungi reach the joint through the bloodstream or from nearby tissues, leading to joint inflammation, swelling, warmth, and sometimes fever. It’s distinct from autoimmune arthritis, where inflammation is triggered by the immune system without an infectious source. It’s also not a fracture or a hernia, which involve bones or tissue protrusion rather than a joint infection. Because the infection can rapidly damage joint surfaces, prompt treatment with appropriate antibiotics and often joint drainage is essential.
