Which clinical manifestation is associated with rheumatic fever?

Polyarthritis is a key clinical manifestation associated with rheumatic fever. Rheumatic fever is an inflammatory condition that can follow a streptococcal infection, such as strep throat. One of its primary features is the occurrence of polyarthritis, which refers to inflammation affecting multiple joints. This inflammation often leads to swelling, redness, pain, and reduced range of motion in the affected joints.

Polyarthritis in the context of rheumatic fever typically manifests in a migratory pattern, meaning that it may affect one joint and then move to another. This characteristic migratory nature of joint inflammation is a significant diagnostic criterion for rheumatic fever.

While joint swelling and redness, skin rash, and chest pain can be associated with various conditions, including rheumatic fever, polyarthritis specifically identifies the involvement of multiple joints, making it the most indicative manifestation of this disease.
