Can you please tell me how rheumatic fever and rheumatic heart disease differ?

See below: Rheumatic fever can manifest as rheumatic heart disease, but can also manifest as migratory arthritis, central nervous system issues, a rash and/or subcutaneous nodules. All of these conditions arise a few weeks following an untreated streptococcal infection, when the body produced antibodies that reacts with different parts of the body (e.g. The heart, joints, nervous system, etc.).

Disease and complica: Rheumatic fever is a disease that can developed after an infection with streptococcus is not treated early. This can be complicated by rhematic heart disease and arthritis and renal failure, etc.
