Rheumatic fever may lead to increased body temperature; fever is one of the common clinical manifestations of rheumatic fever, primarily associated with streptococcal infections.

Other common symptoms of rheumatic fever include joint pain or arthritis, erythema marginatum, subcutaneous nodules, chorea, and carditis.

During the acute phase, penicillin antibiotics can be used to treat the infection. At the same time, it is important to rest adequately and consume high-quality protein foods to ensure sufficient nutrition and calories. Foods rich in high-quality protein such as lean meat, milk, and eggs should be consumed appropriately.

In addition, symptomatic treatment is also crucial. For arthritis, non-steroidal anti-inflammatory drugs can be used, and corticosteroids are necessary for treating carditis.
