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). The disease can affect the heart, joints, skin, and brain.

Alternative Names

Acute rheumatic fever


Rheumatic fever is common in developing countries worldwide. It does not often occur in the United States and other developed countries. When rheumatic fever does occur in the U.S., it is usually in isolated outbreaks. The latest outbreak in the U.S. was in the 1980s.

Rheumatic fever mainly affects children ages 5 -15 who have had strep throat or scarlet fever. If it occurs, it develops about 14 - 28 days after these illnesses.


Exams and Tests

Your health care provider will examine you and will carefully check your heart sounds, skin, and joints.

Tests may include:

Several factors called major and minor criteria have been developed to help diagnose rheumatic fever in a standard way.

The major criteria for diagnosis include:

The minor criteria include:

You'll likely be diagnosed with rheumatic fever if you meet two major criteria, or one major and two minor criteria, and have signs of a past strep infection.


If you are diagnosed with acute rheumatic fever you will be treated with antibiotics.

Anti-inflammatory medications such as aspirin or corticosteroids reduce inflammation to help manage acute rheumatic fever.

You may have to take low doses of antibiotics (such as penicillin, sulfadiazine, or erythromycin) over the long term to prevent strep throat from returning.

Outlook (Prognosis)

If rheumatic fever returns, your health care provider may recommend you take low-dose antibiotics for a long time, especially during the first 3 -5 years after you first get the disease. Heart complications may be severe, especially if the heart valves are involved.

Possible Complications

When to Contact a Medical Professional

Call your health care provider if you develop symptoms of rheumatic fever. Because several other conditions have similar symptoms, you will need careful medical evaluation.

If you have symptoms of strep throat, tell your health care provider. You will need to be evaluated and treated if you do have strep throat, to decrease your risk of developing rheumatic fever.


The most important way to prevent rheumatic fever is by getting quick treatment for strep throat and scarlet fever.
