Is Streptococcal Infection Syndrome the Same as Rheumatic Fever?

Streptococcal infection itself is not rheumatic fever. Streptococcal infection syndrome refers to a recurrent acute or chronic systemic connective tissue inflammation commonly associated with rheumatic fever, primarily involving the heart, joints, central nervous system, skin, and subcutaneous tissues. Following streptococcal infection, patients frequently develop fever, nasal congestion, and rhinorrhea. However, if left untreated for an extended period, rheumatic fever may develop. During treatment, it is essential to maintain body warmth and practice good personal hygiene.

Rheumatic fever is an autoimmune disease triggered by upper respiratory tract infection with Group A beta-hemolytic streptococcus. It predominantly affects connective tissues throughout the body—especially the joints, heart, and skin—and may also involve the nervous system, blood vessels, serous membranes, and internal organs such as the liver and kidneys.

Typical symptoms of rheumatic fever usually appear 2–6 weeks after an upper respiratory tract streptococcal infection (e.g., pharyngitis or tonsillitis), manifesting as fever, sore throat, enlarged cervical lymph nodes, and cough. Laboratory tests confirming streptococcal infection include positive throat swab culture for streptococci and elevated antistreptolysin O (ASO) titers. During the acute phase, bed rest and easily digestible foods are recommended. We hope this article has been helpful. Wishing you a happy life and good health!
