Rheumatic Fever


Prevention & Expectations

What can be done to prevent the disease?

Effective treatment of strep infections with antibiotics significantly lowers a person's risk of developing rheumatic fever. Individuals with these infections should take their full course of antibiotics, even after symptoms are gone.

What are the long-term effects of the disease?

In 75% of people with rheumatic fever, the acute attack lasts only 6 weeks. Ninety percent of the cases of rheumatic fever resolve in 12 weeks or less. Fewer than 5% of people with rheumatic fever have symptoms that last for 6 months or more.

There are many possible complications as a result of rheumatic fever. They can include the following:

  • anemia, which is a low red blood cell count
  • arrhythmias, or abnormal heart rhythms
  • arthritis
  • bacterial pericarditis, an inflammation of the sac surrounding the heart
  • congestive heart failure, a condition in which the weakened heart is unable to pump blood effectively throughout the body
  • endocarditis, which is an inflammation of the lining of the heart
  • heart valve damage, including mitral stenosis and mitral valve prolapse
  • proteinuria, a condition in which protein is lost in the urine
  • skin disorders
  • Sydenham chorea, a nervous system disorder that causes involuntary, writhing movements
  • What are the risks to others?

    Rheumatic fever itself is not contagious and poses no risk to others. However, the streptococcal infection can be highly contagious.
