Rheumatic fever is a relatively easy recurrence of the disease, the specific how long will recur with the patient’s daily protection and disease prevention and other factors, generally speaking, the recurrence rate of 10 years is about 60%. Rheumatic fever is a recurrent acute and chronic systemic connective tissue disease caused by infection with group A beta-hemolytic streptococcus. Most patients with rheumatic fever have a good recovery with timely treatment, but a small number of patients with cardiac involvement in the first episode have a poorer prognosis. For patients who are stabilized after treatment, if they pay attention to daily care and disease prevention, they can keep the disease for a relatively long time without relapse, but if the patient’s condition is critical and involves the heart, then there may be a relapse in a relatively short period of time. All in all, the recurrence rate for all such patients is about 60% within 10 years. If there are symptoms such as rash, fever, joint pain, etc., and recurrence is suspected, it is necessary to consult a doctor in time.
