Rheumatic fever is caused by a delayed immune response to group A beta-hemolytic streptococcal infection. It primarily affects the heart, joints, subcutaneous tissue, and brain. It is more common in developing countries and affects children between 5-15 years old. Symptoms include arthritis, carditis, Sydenham's chorea, subcutaneous nodules, and erythema marginatum. Diagnosis is based on modified Jones criteria and treatment involves antibiotics, anti-inflammatories, and long-term prevention of recurrent infections.
