Rheumatic fever is a serious inflammatory condition that can have lasting effects on the heart, joints, and nervous system. This illness primarily affects children and young adults, often following a streptococcal throat infection. Despite advancements in medical care, rheumatic fever continues to be a significant health concern, particularly in developing countries where access to healthcare may be limited.
This article aims to provide a comprehensive overview of rheumatic fever, covering its symptoms, diagnosis, and management. It will explore the underlying causes of the condition, discuss the importance of early detection, and outline current treatment approaches. Additionally, the article will examine prevention strategies and long-term implications for those affected by rheumatic fever, offering valuable insights for patients, caregivers, and healthcare professionals alike.
Understanding Rheumatic Fever
Rheumatic fever is an inflammatory disease that may develop after an infection with group A streptococcus bacteria, such as strep throat or scarlet fever. It primarily affects children between the ages of 5 and 15, although younger children and adults can also be affected. The disease is rare in the United States and other developed countries but remains a significant health concern in developing nations.
Definition
Rheumatic fever is an autoimmune condition that occurs when the body’s immune system overreacts to an untreated strep throat or scarlet fever infection. This abnormal reaction causes swelling or inflammation in various tissues, including the heart, joints, skin, and brain.

Causes
The exact mechanism by which a strep infection leads to rheumatic fever is not clear. However, it is believed that the bacteria trick the immune system into attacking healthy tissues in the body. This incorrect immune response results in inflammation and swelling of the affected tissues, primarily in the heart, joints, skin, and central nervous system.
Risk Factors
Several factors may increase the risk of developing rheumatic fever:
- Genetics: Some individuals may have one or more genes that make them more susceptible to developing rheumatic fever.
- Specific strep bacteria strains: Certain strains of streptococcus bacteria are more likely to cause rheumatic fever than others.
- Environmental factors: Overcrowding, poor sanitation, and other conditions that facilitate the easy spread of strep bacteria among people can increase the risk of rheumatic fever.
Rheumatic fever can lead to long-lasting complications, particularly rheumatic heart disease, which occurs when the heart valves are damaged. Prompt treatment of strep throat with antibiotics is crucial in preventing the development of rheumatic fever and its potential complications.
Recognizing Symptoms
Rheumatic fever can have a wide range of symptoms, some more common than others. The disease primarily affects children between the ages of 5 and 15, usually developing two to three weeks after an untreated strep throat or scarlet fever infection.
Common Signs
One of the most recognizable symptoms of rheumatic fever is a red, jagged rash known as erythema marginatum. Other common signs include:
- Swollen, tender, and red joints (arthritis), particularly in the knees, ankles, and elbows
- Jerky, uncontrollable movements in the hands, feet, or other body parts (chorea)
- Small, painless bumps (nodules) under the skin
- Chest pain or an abnormal heartbeat
- Fatigue
- Fever
- Muscle aches
- Swollen, red tonsils

Rare Symptoms
In some cases, rheumatic fever may cause less common symptoms such as:
- Unexplained or persistent headaches, especially if the child has not previously complained of head pain
- Shortness of breath or weakness, which could indicate heart inflammation (carditis)
- Pericardial friction rubs or leakage of blood from vessels into heart tissue, also signs of carditis
When to See a Doctor
It is crucial to seek medical attention if a child has had a sore throat for more than a couple of days or if they exhibit any of the symptoms mentioned above. Early diagnosis and treatment of strep throat can prevent the development of rheumatic fever.
If a healthcare provider suspects rheumatic fever, they will perform a physical examination and may order tests such as a throat swab, blood tests, or heart tests (electrocardiogram or echocardiogram) to confirm the diagnosis. Prompt treatment with antibiotics and anti-inflammatory medications can help manage the condition and prevent long-term complications.
Diagnosis and Treatment
Diagnosing rheumatic fever involves a combination of clinical evaluation, medical history, and diagnostic tests. There is no single definitive test for acute rheumatic fever. Doctors use the Jones criteria to make a clinical diagnosis, which includes assessing major and minor manifestations along with evidence of a preceding group A streptococcal infection.
Diagnostic Tests
- Blood tests: These include C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) to check for inflammation. Antibody tests can detect proteins related to strep bacteria.
- Electrocardiogram (ECG or EKG): An ECG shows how the heart is beating and can help diagnose irregular heartbeats and signs of heart swelling.
- Echocardiogram: This test uses sound waves to create pictures of the heart in motion, showing its structure and blood flow. It can reveal any damage caused by rheumatic fever.
Treatment Options
The goals of treatment for rheumatic fever are to treat the infection, ease symptoms, control inflammation, and prevent the condition from returning. The following medications are used:
- Antibiotics: Penicillin or another antibiotic is given to eradicate the strep bacteria. Long-term antibiotic prophylaxis may be necessary to prevent recurrence.
- Anti-inflammatory drugs: Aspirin or naproxen can help reduce inflammation, fever, and pain. Corticosteroids may be prescribed for severe symptoms.
- Antiseizure drugs: Medications may be used to treat severe involuntary movements caused by Sydenham chorea.
Long-term Management
Regular health checkups are crucial after having rheumatic fever, as heart damage may not show up for many years. Patients with rheumatic heart disease require ongoing care, including:
- Secondary antibiotic prophylaxis: This can reduce the long-term severity of rheumatic heart disease. The recommended regimen is benzathine benzylpenicillin G intramuscular injections every four weeks for a minimum of 5-10 years or until 21 years of age, whichever is longer.
- Endocarditis prophylaxis: Patients with rheumatic heart disease should receive amoxicillin prophylaxis before undergoing high-risk dental or surgical procedures.
- Cardiology services and echocardiographic follow-up: These are required for patients with moderate to severe rheumatic heart disease.
Prompt diagnosis and appropriate treatment of rheumatic fever are essential to prevent long-term complications and manage rheumatic heart disease effectively.
Preventing Rheumatic Fever
Preventing rheumatic fever is crucial, as it can have serious long-term effects on the heart, joints, and nervous system. The most effective way to prevent rheumatic fever is through early diagnosis and treatment of streptococcal infections, such as strep throat and scarlet fever.
Importance of Early Strep Treatment: Prompt treatment of streptococcal infections with antibiotics is essential in preventing the development of rheumatic fever. When a child is diagnosed with strep throat or scarlet fever, it is crucial to follow the healthcare provider’s instructions carefully and complete the full course of antibiotics, even if the child starts feeling better. Failure to do so may allow the infection to linger and increase the risk of rheumatic fever.

Hygiene Practices: Practicing good hygiene can help reduce the spread of streptococcal infections and lower the risk of developing rheumatic fever. Encourage children to:
- Wash their hands frequently with soap and water
- Cover their mouth and nose when coughing or sneezing
- Avoid sharing personal items, such as utensils, cups, or towels
Antibiotic Prophylaxis: For children who have had rheumatic fever, long-term antibiotic prophylaxis may be recommended to prevent recurrent episodes. This typically involves monthly injections of penicillin or daily oral antibiotics. The duration of prophylaxis depends on several factors, including the child’s age, the severity of the initial rheumatic fever episode, and the presence of cardiac involvement. Regular follow-up with a healthcare provider is essential to monitor the child’s condition and adjust the prophylaxis regimen as needed.
Conclusion
Rheumatic fever remains a significant health concern, particularly in developing countries. This article has shed light on its causes, symptoms, diagnosis, and treatment options. Understanding the importance of early detection and proper management is crucial to prevent long-term complications. By focusing on prompt treatment of strep infections and maintaining good hygiene practices, we can make strides in reducing the incidence of this serious condition.
Looking ahead, continued research and awareness efforts are needed to further improve prevention strategies and treatment outcomes. Healthcare providers play a vital role in educating patients and their families about the risks associated with rheumatic fever. With ongoing vigilance and proper care, we can work towards minimizing the impact of rheumatic fever on individuals and communities worldwide.
