M01.8: Arthritis in other infectious and parasitic diseases classified elsewhere

"Arthritis in other infectious and parasitic diseases classified elsewhere" refers to a type of arthritis caused by an infection or parasitic disease that is not typically associated with arthritis. This condition might occur when the infectious agent (bacteria, virus, or parasite) travels through the bloodstream to the joints, or if an infection nearby spreads to the joint. Symptoms can vary but usually include joint pain, swelling, stiffness, redness and warm sensation around the affected joint, and sometimes fever. The onset can be abrupt or gradual, depending on the underlying cause. The disease progression and severity depend on the infectious or parasitic agent causing the arthritis. It's important to get an accurate diagnosis as some types of this arthritis can cause permanent damage to the joint if left untreated.
