Scarlet fever, also known as scarlatina, is an infectious disease caused by Streptococcus pyogenes, a Group A streptococcus (GAS). [3] It most commonly affects children between five and 15 years of age. [1] The signs and symptoms include a sore throat, fever, headache, swollen lymph nodes, and a characteristic rash. [1]
The two most prominent infections of GAS are both non-invasive: strep throat (pharyngitis) where it causes 15–30% of the childhood cases and 10% of adult cases, and impetigo.
