Rheumatic fever is an inflammatory disease that can develop as a complication of inadequately treated strep throat or scarlet fever. Strep throat and scarlet fever are caused by an infection with streptococcus bacteria.

Rheumatic fever is the most common in children, though Although strep throat is common, rheumatic fever is rare in New Zealand and other developed countries. However, the rheumatic fever remains common in many developing nations.

Damage to the heart, including damaged heart valves and heart failure. Treatments can reduce damage from inflammation, lessen pain and other symptoms, and prevent recurrence of rheumatic fever.


Rheumatic fever symptoms vary. During the course of the disease. The onset of rheumatic fever usually occurs after the strep throat infection.

Rheumatic fever signs and symptoms – which can be associated with inflammation, can be:

  • Fever
  • Most often in the knees, ankles, elbows and wrists
  • Pain in one joint
  • Red, hot or swollen joints
  • Small, painless bumps (nodules) beneath the skin
  • Chest pain
  • Heart murmur
  • Fatigue
  • Flat or slightly raised, painless rash with a ragged edge (erythema marginatum)
  • Jerky, uncontrollable body movements (Sydenham chorea, or St. Vitus’ dance) – most often in hands, feet and face
  • Outbursts of unusual behavior, such as crying or inappropriate laughing, that accompanies Sydenham chorea

When should you go to the doctor?

Have a look at strep throat. Proper treatment of strep can prevent rheumatic fever. It shows other indications of rheumatic fever.


Rheumatic fever can occur with an bacterium called a streptococcus group. Group A throat cause strep throat or, less commonly, scarlet fever. Group A rarely trigger rheumatic fever.

Bacterium tricks the immune system. The bacterium strep contains a body of protein. It is the skin of the heart and the nervous system. This immune system reaction results in inflammation.

If your child receives a bacteria treatment, it is recommended that you get a chance to develop. It is not necessary to cure any form of rheumatic fever.

Risk factors

The factors that can increase include:

  • Family history. It would be more likely to develop a rheumatic fever.
  • Type of strep bacteria. Certain strains of bacteria are more likely to contribute to
  • Environmental factors. It has been shown that there has been a lot of risk.


Inflammation caused by few months to several months. In some cases, the inflammation causes long-term complications.

Caused by rheumatic fever. It usually occurs 10 to 20 years after the original illness. Two chambers of the heart (mitral valve) can be affected. The damage can result in:

  • Valve stenosis. This is a narrowing of the valve reduced blood flow.
  • Valve regurgitation. This is a leak.
  • Damage to heart muscle. The inflammation associated with rheumatic fever can weaken the heart muscle, affecting its ability to pump.

Damage to the heart valve. Resulting conditions can include:

  • An irregular and chaotic beating of the upper chambers of the heart (atrial fibrillation)
  • Blood to the body (heart failure)
  • Prevention
  • If you’re trying to get rid of the antibiotics, it’s safe to use.
