Table of Contents
Acute rheumatic fever is a rare but serious condition that can develop after an untreated streptococcal infection, such as strep throat. The immune system's response to the infection may mistakenly attack healthy tissues, leading to inflammation in different parts of the body, including the heart, joints, skin, and brain. Early medical care is important for reducing the risk of complications and managing the condition effectively.
What Are the Types of Acute Rheumatic Fever?
Acute rheumatic fever can present in different forms depending on the organs affected. The condition may involve the heart or appear with symptoms affecting other parts of the body.
- Cardiac type: affects the heart and may cause inflammation of the heart valves, sometimes leading to long-term heart complications.
- Non-cardiac type: involves the joints, skin, and nervous system.
- Sydenham's chorea: characterized by sudden, uncontrolled movements of the limbs, face, and trunk along with emotional instability.
- Erythema marginatum: painless pink or red rashes with well-defined borders appearing on the trunk or inner arms and thighs.
- Subcutaneous nodules: small, firm, painless lumps that develop under the skin near joints like elbows or knees.
What Are the Symptoms of Acute Rheumatic Fever?
The symptoms of acute rheumatic fever usually appear a few weeks after a streptococcal throat infection. These symptoms may affect several organs and can vary from mild to severe.
- Sudden joint pain and swelling, especially in the knees, elbows, or wrists.
- Unexplained fever and persistent fatigue that does not improve with rest.
- Skin rashes that may appear in patterns resembling a map.
- Shortness of breath, chest pain, or palpitations caused by heart inflammation.
- Sudden jerky movements or uncontrollable twitching of the hands, feet, or face.
- General weakness and a feeling of overall illness.
What Causes Acute Rheumatic Fever?
Acute rheumatic fever usually develops when the body's immune system reacts to a streptococcal infection and mistakenly attacks healthy tissues. Several factors can increase the chances of this immune reaction.
- Untreated or inadequately treated streptococcal infections, especially group A Streptococcus.
- Genetic predisposition or a family history of the condition.
- Delayed treatment of throat infections due to limited access to healthcare.
- Overcrowded living conditions and poor sanitation allow infections to spread more easily.

- Persistent fever, joint pain, or swelling following a sore throat.
