In this episode, Dr. Krishan and Dixie Crawford discuss Rheumatic Heart Disease (RHD), a condition that affects the valves inside the heart.1 RHD is caused by an abnormal immune response to a bacterial infection caused by a bacteria called strep A that are found in the throat and on the skin.2 The infection is spread through respiratory secretions, such as saliva or mucus. 2 Symptoms of strep A infection include sore throat, fever, pain when swallowing, fatigue, and body aches.2 It is important to seek medical attention if these symptoms are present, especially in children and teenagers.

While strep A infection are common, not all cases will lead to RHD.2 However, it is crucial to prevent and treat strep A infection to reduce the risk of developing RHD. Prevention measures include practicing good hygiene, washing hands regularly, and avoiding close contact with sick individuals. If a sore throat is diagnosed as strep A infection, it should be treated with antibiotics to prevent complications like RHD.2
