M00: Pyogenic arthritis

M00.1: Pneumococcal arthritis and polyarthritis

Pneumococcal arthritis and polyarthritis is a single medical condition characterized by inflammation of one or more joints due to a bacterial infection caused by Streptococcus pneumoniae, a type of bacteria often linked with respiratory infections. While infections typically begin as pneumonia, ear infections, or sinusitis, they can occasionally spread to the joints, triggering the body's inflammation response and leading to arthritis. Symptoms typically include severe joint pain, swelling, and redness, accompanied by general signs of infection such as fever and chills. The knee is most commonly affected, but it can occur in any joint. The severity and progression of the disease may vary, dependent on the individual's immune response and the promptness of medical intervention. It's essential to diagnose and treat pneumococcal arthritis promptly to minimize the risk of long-term joint damage.
