Fever, rheumatic: An illness that occurs following a streptococcus infection (such as a "strep throat") or scarlet fever and predominantly affects children. Symptoms include fever, pain in the joints, nausea, stomach cramps, and vomiting. Rheumatic fever can cause long-lasting effects in the skin, joints, heart, and brain.
The diagnosis of rheumatic fever is made by history and observation. An ASO or anti-DNAse B lab test can help make the diagnosis.
Treatment is usually by prophylactic antibiotics, as recurrence is common and can cause further damage to body tissues.
