What is scarlet fever?
Scarlet fever is a bacterial infection. The disease used to be more common and severe, but now it is treatable. However, it can cause harmful health problems if left untreated. Scarlet fever is linked to a rash, hence the name “scarlet.”
Symptoms of scarlet fever
Children ages 5 to 15 are at greatest risk of getting scarlet fever. Symptoms often begin within 1 or 2 days of infection. The most common symptoms are fever, sore throat, and a rash. The rash can cover your neck, chest, arms, and legs. It consists of small, rough, red bumps that can peel.
You may have other symptoms, such as:
- swollen tongue, tonsils, or glands
- white coating or red bumps on tongue
- stomach pain
- muscle aches
What causes scarlet fever?
Group A streptococcus bacteria causes scarlet fever. This is the same infection that causes strep throat and can lead to rheumatic fever. Scarlet fever spreads through with an infected person or their germs.
How is scarlet fever diagnosed?
Visit your doctor right away if you think you have scarlet fever. They will do a physical exam and review your symptoms. They also will do a throat culture or blood test to check for a strep infection.
Can scarlet fever be prevented or avoided?
There is no vaccine for scarlet fever. The only way to prevent it is to avoid sick people. This way you reduce your risk of catching the infection. If you have scarlet fever, you should stay home from work or school and avoid travel.
Scarlet fever treatment
If you have scarlet fever, your doctor will prescribe antibiotics. These will kill the bacteria in your body. They will make you not contagious after 24 hours. Make sure you take all of the medicine to get rid of the infection.
Living with scarlet fever
With treatment, you can recover from scarlet fever. The rash may take a few weeks to go away.
If you have scarlet fever and do not treat it, you’re at risk. It can lead to rheumatic fever, which can cause serious health problems. Complications are rare, but can include kidney, liver, or heart damage. You may get an ear, sinus, or skin infection, pneumonia, or arthritis. In rare cases, the bacteria can get into an open wound and your bloodstream. This can cause sepsis, which is life threatening.
Call your doctor if your condition does not improve after 24 hours of treatment or if you get new or worse symptoms.
