Scarlet Fever
Scarlet fever, also called "scarlatina", is caused by Group A streptococcus (group A strep), a bacterium commonly found in the throat and on the skin. These bacteria also cause strep throat. Scarlet fever often appears as a rash and is accompanied by a high fever and a strawberry-like appearance of the tongue. The illness is most common among children aged 5 to 18 years, but adults can also become infected.
