In this chapter:

Rheumatic fever is a serious illness with joint pain and fever. It usually lasts about 6 weeks but may last up to 6 months (or rarely more). Then the joint pain usually goes away completely. But heart damage, if it has occurred, may be permanent or become disabling (shortness of breath; sickly child).

Signs of a typical case
  • Child between the ages 5 to 15
  • Began 1–3 weeks after the child had a severe sore throat
  • High fever— child quite sick

  • Joint pain. Pain often starts in one or more of the larger joints (especially wrists and ankles). Then it changes to other joints, often knees and elbows. The painful joints may swell and become red and hot.
  • Child gets well in about 6 weeks to 3 months, but may get the same illness again after another sore throat.
Other signs (not always present)
  • Reddish curved lines or rash on skin
  • Lumps (the size of peas) under the skin over or near the joints
  • Heart problems. You may hear a ‘murmur’ if you put your ear over the child’s chest. Instead of the typical ‘lub-dub . . . lub-dub’ of the heartbeat, you will hear a soft, long ‘whoosh’ for one of the sounds: ‘whoosh-dub ... whoosh-dub ... whoosh-dub’. The ‘whoosh’ sound means a valve to the heart has been damaged so that it does not close completely. In extreme cases this can lead to heart failure (see Where There Is No Doctor, p. 325).
  • Nosebleed, belly pain, chest pain, or signs of pneumonia occur in only a few cases.
Causes

Rheumatic fever usually results after a sore throat caused by bacteria called ‘streptococcus’. (The rheumatic fever is somewhat like an allergic reaction.) A ‘strep throat’ often starts suddenly with throat pain and fever and without signs of a cold. Rheumatic fever is most common where epidemics of strep throat are common— in crowded communities with poor hygiene.

Prevention

Rheumatic fever can often be prevented by giving penicillin to children who have signs of a strep throat. Keep giving penicillin for at least 3 days after all signs disappear. Long-term prevention involves improving hygiene and living conditions (a fairer society).

CAUTION! Most sore throats in children are not ‘strep’, but are caused by the common cold; these should not be treated with penicillin, or any other antibiotic and never injections. Typically, a strep throat is quite painful and starts suddenly, with high fever, and without a stuffy nose or other signs of a cold.
Treatment
  • If you think a child might have rheumatic fever, get medical advice quickly. Early treatment may help prevent heart damage. (After fever and joint pain have begun, treatment does not seem to shorten the length of the illness.)
  • Give penicillin V by mouth for 10 days; or give a single injection of benzathine benzylpenicillin into the buttock muscles (one-half in each buttock); or inject procaine penicillin daily for 10 days. For children allergic to penicillin, use erythromycin. See box for doses. (For cautions in the use of penicillin, see Where There Is No Doctor, p. 351.)
  • Give aspirin or ibuprofen in high dosage. See INFORMATION SHEET. Continue giving the medicines until a few days after all signs are gone.
  • Apply heat or cold packs to painful joints to help reduce pain and swelling.
  • Do full range-of-motion exercises of painful joints gently every day.
  • Do ‘exercises without motion’ to maintain strength.
  • The child should stay in bed or rest quietly most of the time until all signs are gone (about 6 weeks). Then he can begin activities little by little.

Note: : It is safer to give children medicines by mouth rather than by injection whenever possible. See precautions in giving medicines to children.


Prevention of repeat attacks

Persons who have once had rheumatic fever have a risk of getting it again. For these persons, take care to treat any sore throat quickly with penicillin. If the person shows signs of heart damage (murmur) with the first attack, there is a high risk of further damage with repeat attacks. These persons would be wise to take a preventive dose of penicillin regularly for at least one attack-free year or until they are 17 years old (after which the risk of strep throat is lower). Long-term prevention is especially important in persons who already have serious rheumatic heart damage.
