What is Scarlet Fever?
Scarlet fever is a bacterial infection, caused by the same bacteria as strep throat, that causes a distinctive pink-red rash with a rough, sandpaper-like texture, along with a sore throat, fever, and a red, swollen tongue sometimes called a "strawberry tongue." It mostly affects children between 2 and 8 years old.
It's treated with antibiotics, which usually lead to rapid improvement and reduce the small risk of complications and the period of contagiousness. With prompt treatment, most children recover fully within about a week.
02 · Understand
Clinical context
Antibiotics reduce both complications and spread
Starting antibiotics promptly not only helps your child recover faster but also significantly reduces how long they remain contagious to others.
03 · Act
When to See a Doctor
- 1You suspect scarlet fever based on the rash, sore throat, and fever pattern
- 2Symptoms don't improve within a few days of starting antibiotics
- 3Your child develops joint pain or swelling after apparently recovering
- 4Your child seems increasingly unwell despite treatment
04 · Prevent & manage
Practical steps
Complete the Full Course of Antibiotics
Even once your child feels better, finishing the entire prescribed course of antibiotics is important to fully clear the infection and reduce the (rare) risk of complications.
- 1Give antibiotics exactly as prescribed.Complete the full course, even after symptoms improve.
- 2Offer plenty of fluids.This helps with the fever and supports recovery.
- 3Give paracetamol or ibuprofen for discomfort.Follow package instructions for your child's age and weight.
- 4Keep your child home until 24 hours after starting antibiotics.This is generally when they're no longer considered contagious.
- 5Offer soft, cool foods if the throat is sore.These are easier to manage than hot or rough-textured foods.
