It's most common in young children but can affect people of any age.
It can be serious therefore it's important to be able to spot the signs of infection, so you can get early treatment and stay away from others to prevent it spreading.
The first signs of scarlet fever can be flu-like symptoms, including a high temperature, a sore throat, and swollen neck glands (a large lump on the side of your neck).
If you suspect that you or your child has scarlet fever, contact your GP.
Follow the NHS guidance on what to do if you or your child has scarlet fever.
To prevent the spread of scarlet fever:
- stay away from nursery, school or work for at least 24 hours after starting the antibiotic treatment if the illness is confirmed
- wash your hands often with soap and water
- use tissues to catch the germs from cough and sneezes, and throw away used tissues in the bin as soon as you can and then wash your hands
- don't share cutlery, cups, beakers, towels, bedding or baths with anyone who has symptoms of scarlet fever
- follow advice given by a health care professional
