Scarlet fever is an illness that appears as a red (scarlet) rash on the body. It is caused by the same bacteria that causes strep throat. Scarlet fever was once a serious childhood illness. Now it can be treated with medicine and home care. Children generally recover from scarlet fever within a week after starting treatment.
Scarlet fever is caused by strep (Streptococcus) bacteria. This is the same bacteria that causes strep throat.
Scarlet fever can be spread in the following ways:
Breathing infected air (the germs can enter the air when an infected person coughs or sneezes)
Contact with fluids (such as nasal fluids) from an infected person
Contact with items (such as cups, toothbrushes, or towels) that have been contaminated by an infected person
Symptoms usually appear 24 to 48 hours after exposure. These include:
A red rash that appears most often on the chest, back, or belly (abdomen). This rash is also called sandpaper rash because it raises the skin and makes it feel like sandpaper. The rash may come before other symptoms or up to a week after.
Sore throat (strep throat)
Other symptoms that may occur include:
Paleness around the mouth
Strawberry tongue (white coating and red spots appear on the tongue, making it look like a strawberry)
As the rash fades you may notice some peeling skin. This is often seen around the fingers, toes, and groin area.
Your child’s healthcare provider asks about your child’s symptoms and health history. Your child is examined. If the provider thinks your child has scarlet fever, he or she will swab the back of your child’s throat to check for strep bacteria.
Scarlet fever generally lasts about 7 to 10 days. The fever and sore throat go away within 48 to 72 hours of starting treatment. The rash may take 7 days to go away. Some peeling or flaking of the skin is normal.
Antibiotics are prescribed by the healthcare provider. These can be given by shot (injection) or by mouth. Make sure your child takes all of the medicine, even if he or she feels better.
Your child is no longer contagious 24 hours after starting treatment. He or she can go back to school or daycare following full recovery.
Use children’s strength medicine for sore throat symptoms. Discuss all over-the-counter (OTC) products with your child’s provider before using them. Note: Don’t give OTC cough and cold medicines to a child younger than 6 years old unless the provider tells you to do so. Never give aspirin to a child under age 18. (It could cause a rare but serious condition called Reye syndrome). Never give ibuprofen to an infant age 6 months or younger.
Anyone in the family who has similar symptoms over the next 5 days should be checked for a possible strep infection.
