Streptococcal reactive arthritis refers to acute non-suppurative arthritis secondary to infection of other parts of the patient’s body, such as the tonsils, with pathogens such as streptococcus. Bacteria, viruses, chlamydia, and other pathogens can cause reactive arthritis after infection, and streptococcus is an important cause of reactive arthritis. Patients may experience low-grade fever, malaise, general malaise, myalgia, and other discomforts, and the onset of the disease is usually more acute, and a history of respiratory tract infections and urinary tract infections usually exists a few weeks or days prior to the onset of reactive arthritis. Reactive arthritis may be complicated by prostatitis, cystitis, keratitis, and aortic insufficiency, but most patients with reactive arthritis have a good prognosis after treatment. It is recommended to use penicillin and other anti-infective treatment as prescribed by the doctor. Patients diagnosed with reactive arthritis are advised to go to the rheumatology and immunology department of regular hospitals for detailed consultation.
