Scarlet fever, sometimes called scarlatina, is a disease caused by a bacteria called group A Streptococcus or "group A strep", the same bacteria that causes strep throat. Scarlet fever is a rash that sometimes occurs in people that have strep throat. People with scarlet fever typically also have a high fever and a strawberry-like appearance of the tongue. The rash of scarlet fever is usually seen in children under the age of 18.
This illness can be caught from contact with the sick person because this germ is carried in the mouth and nasal fluids. The disease can be spread through contact with droplets shed when an infected person coughs or sneezes. If you touch your mouth, nose, or eyes after touching something that has these fluids on them, you may become ill. Also, if you drink from the same glass or eat from the same plate as the sick person, you could also become ill. The best way to keep from getting sick is to wash your hands often and avoid sharing eating utensils. It is especially important for anyone with a sore throat to wash his or her hands often and not share eating or drinking utensils.
Scarlet fever begins with a rash that shows up as tiny red bumps. It most often begins on the chest and stomach but can then spread all over the body. It looks like a sunburn and feels like a rough piece of sandpaper. Most of the time it is redder in the creases of the elbows, arm pits, and groin areas. The rash lasts about 2-7 days. After the rash is gone, the skin on the tips of the fingers and toes begins to peel.
Some other common signs of scarlet fever are:
To diagnose the cause of your child’s rash or sore throat, your doctor or healthcare provider will examine your child and swab the back of the throat with a cotton swab. The swab will be then used for a throat culture or a rapid antigen test (sometimes called a “rapid strep test”) to see if there is a group A strep infection.
Scarlet fever can be treated with antibiotics.
