An inflammatory disease following infection by the bacteria that causes strep throat. It is thought to be caused by the immune system attacking proteins in the heart, joints, skin, and brain that are similar to those found in the bacteria. It leads to a numbber of serious side effects, particularly heart disease. It is now rare in the United States due to widespread treatment of strep throat and other infections with antibiotics.
