Scarlet Fever was a feared and often fatal childhood disease, particularly in the 19th and early 20th centuries, before the discovery of antibiotics. Its incidence dramatically declined with the introduction of penicillin. However, there have been periodic resurgences of Scarlet Fever in various parts of the world in recent decades.
Scarlet Fever spreads through respiratory droplets when an infected person coughs or sneezes. It can also be transmitted through direct contact with infected saliva or nasal secretions, or by touching contaminated surfaces and then touching one's mouth or nose. Close contact in crowded environments facilitates its spread.
