Spread of the infection to other areas such as the ears, sinuses, or lungs
Streptococcal toxic shock syndrome
You will be asked about your symptoms and medical history. A physical exam will be done. The doctor may diagnose scarlet fever by the specific rash. Confirmation of scarlet fever can be done with a throat swab or rapid strep antigen detection test.
The infection that causes scarlet fever can be treated with antibiotics. It is important to take all the prescribed medication. Doing so will prevent scarlet fever from returning, and also prevent complications.
There is no specific treatment for the rash. After the rash fades, the skin peels for several weeks.
To help reduce the chances of scarlet fever:
Avoid contact with people who have untreated strep infections.
Wash your hands frequently.
Have other household members or contacts tested for strep infection.
