Rheumatic Fever In Children: What Every Parent Should Know

Published By Affinity News

August 11, 2025

Affinity Health, a leading provider of high-quality health cover, highlights the need for awareness around rheumatic fever in children. This often-overlooked illness can lead to lifelong heart damage if left untreated. This message is essential during Rheumatic Fever and Rheumatic Heart Disease Awareness Week, observed from 4 to 10 August.
“Many parents have never even heard of rheumatic fever,” says Murray Hewlett, CEO of Affinity Health.
“Yet it remains a serious threat to children’s health, especially in under-resourced communities.”
According to the World Health Organization (WHO), rheumatic heart disease, caused by untreated rheumatic fever, leads to more than 288,000 deaths globally each year, primarily affecting children and young adults in low-resource settings. Early detection and consistent use of antibiotics are critical to preventing this long-term, life-threatening condition.

What Is Rheumatic Fever?

Rheumatic fever is an inflammatory disease that can develop as a complication of untreated or poorly treated strep throat or scarlet fever. It typically affects children between the ages of 5 and 15 and can cause long-term damage to the heart, joints, skin, and brain.
The condition is triggered by the body’s immune response to a Group A Streptococcus (strep) infection. Instead of attacking the bacteria alone, the immune system also targets healthy tissue, particularly in the heart valves. This can lead to rheumatic heart disease (RHD), a chronic, disabling, and potentially fatal condition.

Why Parents Should Be Concerned

Rheumatic heart disease remains a serious but preventable condition linked to untreated streptococcal throat infections. A lack of awareness, limited access to early treatment, and overcrowded living conditions, where infections spread quickly, contribute to high rates of illness. Many children suffer irreversible heart damage simply because a sore throat wasn’t treated promptly with antibiotics.

Symptoms of Rheumatic Fever in Children

Parents should be aware of these warning signs, especially following a sore throat or fever:

  • Fever and joint pain or swelling, especially in the knees, ankles, elbows, or wrists.
  • Fatigue and shortness of breath.
  • Unusual movements (such as jerky arm or facial movements).
  • Red skin rashes or lumps under the skin.
  • Rapid heartbeat or chest pain.

If your child shows any of these symptoms, especially after a recent sore throat, it’s important to see a doctor immediately.

How Is It Diagnosed and Treated?

Doctors will typically run tests such as a throat swab, blood test, and echocardiogram to confirm rheumatic fever. If caught early, treatment includes:

  • Antibiotics to clear any remaining strep bacteria.
  • Anti-inflammatory medication (such as aspirin or corticosteroids) to reduce swelling and pain.
  • Long-term antibiotics to prevent recurrence (sometimes for years, depending on heart involvement).
  • Monitoring and specialist referral if the heart is affected.

With proper medical care, most children recover fully. However, without it, repeated infections can permanently damage heart valves.

Can Rheumatic Fever Be Prevented?

Yes. Prevention starts with something as simple as treating a sore throat seriously, rather than ignoring it until it goes away. Always seek medical advice if your child complains of a persistently painful throat, fever, or difficulty swallowing. Complete the full course of antibiotics as prescribed—even if your child starts feeling better.
Encourage good hygiene practices like regular handwashing and avoiding sharing utensils or cups. In areas where healthcare access is limited, community education and school health programmes can play a key role in early detection.

The Long-Term Impact

Suppose rheumatic fever causes scarring of the heart valves. In that case, the child may later develop rheumatic heart disease, which can result in heart failure, stroke, or the need for valve replacement surgery in adulthood. Sadly, many children living with RHD are only diagnosed once irreversible damage has occurred.
What Parents Can Do

  • Don’t ignore sore throats—seek medical attention.
  • Ensure children complete prescribed antibiotics.
  • Teach good hygiene and throat care.
  • Watch for signs of joint pain, rash, or fatigue after illness.
  • Ask your clinic about follow-up care if your child has had rheumatic fever.

Conclusion

Rheumatic fever is entirely preventable, but only if parents and caregivers know what to look out for and take early symptoms seriously. A simple sore throat, when left untreated, can lead to a lifetime of heart complications for a child. That’s why awareness, early diagnosis, and completing the full course of prescribed antibiotics are so vital.
