How do you get rheumatic fever?

The main causes of rheumatic fever include genetic factors, streptococcal infection, abnormal immune function, etc.

1. Genetic factors

If the patient's parents are rheumatic fever patients and carry pathogenic genes, the risk of rheumatic fever is greatly increased.

2. Streptococcal infection

If streptococci exist in the patient's body and continue to multiply, they cannot eliminate streptococci in time, and will continue to multiply and release toxins, causing rheumatic fever.

3. Abnormal immune function

If the patient's immune system is stimulated by pathogens, triggering an immune response, causing the body's immune system to attack its own tissues, causing rheumatic fever.
