Scarlet fever
Scarlet fever is a bacterial infection that often develops in people who have strep throat. It's characterized by a bright red rash that covers most of the body, often feeling like sandpaper. While it can look alarming, it's usually not serious and is easily treated with antibiotics.
Common symptoms
- Bright red rash that feels like sandpaper
- Flushed face with a pale area around the mouth

Cause
Scarlet fever is caused by a type of bacteria called Group A Streptococcus (GAS), the same bacteria that causes strep throat.
How common is it?
Scarlet fever, caused by group A Streptococcus, primarily affects children ages 5-15. While exact U.S. incidence data is limited, scarlet fever remains relatively common, often following strep throat. Recent years have seen increased cases in some regions. Prompt antibiotic treatment prevents complications.
Treatment
Scarlet fever is treated with antibiotics prescribed by a doctor. It's crucial to complete the entire course of antibiotics, even if your child feels better, to prevent complications. Pain relievers like acetaminophen or ibuprofen can help manage fever and discomfort.
