Rheumatoid arthritis is dominated by joint lesions and does not usually directly affect the life expectancy of the patient. Rheumatoid arthritis is a connective tissue disease associated with group A beta-hemolytic streptococcal infection. Wandering joint swelling and pain are the predominant manifestations, which may be accompanied by regular fever, subcutaneous nodules, and annular erythema, etc. A few patients may develop heart damage. Currently, rheumatoid arthritis is widely studied in the medical community, and the majority of patients can be effectively controlled after receiving anti-streptococcal infection and anti-rheumatic therapy, which will not affect the survival of patients. Therefore, patients with rheumatoid arthritis should receive systematic and standardized treatment as soon as possible after the diagnosis is made to ensure that the disease is adequately controlled.
