Scarlet fever (also known as scarlatina) is a highly contagious disease caused by a toxin released by the strep bacteria, Streptococcus pyogenes. Most people recover from it without complications.
Scarlet fever is spread by close contact with a person having the disease, by breathing in germ-laden air, touching the skin of an infected person or touching the objects that were touched by an infected person. It usually takes two to four days since contact and infection for the first signs to appear. The disease usually lasts from one to two weeks, but the rash may start to clear after four or five days.
No vaccine is available to prevent the disease. A person with scarlet fever should be isolated for seven days from the onset of the disease to prevent infecting others.
The “scarlet” in the name of this disease refers to the pink-red rash, which occurs when the toxins are released.
