The immune systemYour body's built-in defense team that fights off germs and helps you heal. More → misfires and attacks the body's own tissues — particularly joints, heart, brain, and skin. The most serious concern is permanent heart valve damage. Rheumatic fever requires medical treatment with antibiotics and anti-inflammatoryA food or habit that helps calm swelling and redness in the body. More → medicines, and often long-term antibiotic prevention. Home supportive care helps the body through the illness but cannot replace medical management.

Rheumatic fever appears 2–4 weeks after a strep throat or scarlet fever infection. The joints become painful, swollen, and inflamed — often traveling from one joint to another. Fever returns. The heart is affected in many cases: inflammationThe body's natural response to injury — like redness, swelling, or heat around a sore spot.

This disease is entirely preventable: completing antibiotic treatment of strep throat or scarlet fever prevents rheumatic fever. That is the most important message. Once rheumatic fever has started, antibiotics still clear remaining strep, anti-inflammatoryA food or habit that helps calm swelling and redness in the body. More → medicines reduce joint pain and fever, and long-term low-dose antibiotics are often prescribed for years to prevent recurrence. At home, complete bed rest is essential during the active phase — physical activity stresses an inflamed heart. A light, plant-based diet with plenty of fluids, no caffeine, no salt, and no fried or processed foods supports recovery. Citrus fruits and colorful plant foods provide bioflavonoids that may help dampen inflammationThe body's natural response to injury — like redness, swelling, or heat around a sore spot. More →. A gradual return to exercise is always guided by the doctor after inflammation fully resolves.

Common signs

• Joint pain and swelling — often traveling from one joint to another (migratory arthritis)
• High fever returning after an apparent recovery from strep
• Chest pain, shortness of breath, or a rapid heartbeat (signs of heart involvement)
• A pink, ring-shaped rash on the body
• Involuntary jerky movements (Sydenham's chorea)
