Scarlet fever, if left untreated, can cause serious long-term complications including rheumatic fever, kidney disease, pneumonia, arthritis, throat abscesses, ear infections and skin infections, according to Healthline. These complications sometimes result in a lifelong disability, such as when rheumatic fever damages the heart.
