Overview

Scarlet fever is an infection that can happen with strep throat. It is caused by the same bacteria that cause strep throat.

Scarlet fever and strep infections are treated with antibiotics. Treatment can prevent serious problems from a strep infection. The strep infection that causes scarlet fever can be spread to others until you no longer have a fever and until you have taken antibiotics for 24 hours.

The rough, red rash that occurs with scarlet fever usually fades in about a week. After the rash fades, the skin may begin to peel.

How can you care for yourself at home?

• Take your antibiotics exactly as directed. Do not stop taking them just because you feel better. You need to take the full course of antibiotics.
• Until you no longer have a fever and until you have taken antibiotics for 24 hours, avoid contact with other people, especially infants and children. Do not go to work or school. Keep your drinking glass and eating utensils separate, and wash these items well in hot, soapy water.
• Gargle with warm salt water once an hour to help reduce swelling and relieve pain. Use 1 teaspoon (5 mL) of salt mixed in 1 cup (250 mL) of warm water.
• Take an over-the-counter pain medicine, such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve). Read and follow all instructions on the label.
• Be careful when taking over-the-counter cold or influenza (flu) medicines and Tylenol at the same time. Many of these medicines have acetaminophen, which is Tylenol. Read the labels to make sure that you are not taking more than the recommended dose. Too much acetaminophen (Tylenol) can be harmful.
• Try an over-the-counter anesthetic throat spray or throat lozenges, which may help relieve throat pain.
• Drink plenty of fluids. Fluids may help soothe an irritated throat. Warm fluids, such as tea or soup, or something cool, like ice pops, may help relieve throat pain.
• Get lots of rest.
• Do not smoke, and avoid second-hand smoke. If you need help quitting, talk to your doctor about stop-smoking programs and medicines. These can increase your chances of quitting for good.
