How does rheumatic fever typically begin?

Rheumatic fever typically begins as a complication of an infection caused by Group A Streptococcus bacteria, often experienced as strep throat. This bacterial infection triggers an immune response in some individuals, which can mistakenly attack the body’s own tissues, particularly the heart, joints, skin, and brain. Strep throat presents with common symptoms like sore throat, fever, and swollen lymph nodes, and if not properly treated, can lead to rheumatic fever within a few weeks. Thus, recognizing the connection between untreated strep throat and the potential for developing rheumatic fever is crucial for effective prevention and early intervention. Understanding this progression underscores the importance of timely diagnosis and treatment of strep throat to reduce the risk of this serious consequence.
