Study Notes
Scarlet Fever Overview
- Scarlet fever is a bacterial illness, also known as scarlatina
- Characterized by a bright red rash covering most of the body
- Often accompanied by a sore throat and high fever
- Most common in children aged 5 to 15 years old
Learning Objectives
- Identify the causative agent of scarlet fever
- Understand the clinical presentation and complications of the disease
- Recognize the available treatment options
Background
- Scarlet fever develops in some people who have strep throat
- A bright red rash is a key feature that spreads across the body
- Scarlet fever usually comes with a sore throat and high fever
- While once a serious childhood illness, antibiotic treatments have lessened its severity
- Untreated, it can lead to more serious issues, impacting the heart, kidneys, and other organs
Causes
- Caused by streptococcal pyrogenic exotoxins (SPEs) types A, B, and C
- Produced by group A beta-hemolytic streptococci (GABHS)
- Found in secretions and discharges from the nose, ears, throat, and skin
- Spread through droplets expelled when an infected person coughs or sneezes
- Incubation period typically lasts 2 to 4 days
Risk Factors
- Children aged 5 to 15 are more susceptible to scarlet fever
- Transmission is more likely among those in close contact (family members, classmates)
Symptoms
- Red rash: Looks like a sunburn, feels like sandpaper, typically begins on the face/neck and spreads to trunk, arms, and legs; reddened skin turns pale under pressure
- Red lines: Folds of skin around the groin, armpits, elbows, knees, and neck become more deeply red than the surrounding rash
- Flushed face: Face appears flushed with a pale ring around the mouth (circumoral pallor)
- Strawberry tongue: The tongue is red and bumpy, often covered with a white coating
Additional Symptoms
- Fever of 101°F (38.3°C) or higher, possibly with chills
- Very sore and red throat, sometimes with white or yellowish patches
- Difficulty swallowing
- Enlarged, tender lymph nodes in the neck
- Nausea or vomiting
- Headache
How to Spot Scarlet Fever
- Fine red rash, feels like sandpaper
- White coating on tongue that peels after a few days, becoming swollen and red ("strawberry tongue")
- Fever over 38.3°C (101°F)
- Flushed red face, but pale around the mouth
- Swollen glands (lymph nodes) in the neck
Complications
- Rare but possible if bacteria spreads; complications include:
- Abscesses around tonsils
- Swollen neck lymph nodes
- Ear, sinus, and skin infections
- Pneumonia (lung infection)
- Rheumatic fever (heart disease)
- Post-streptococcal glomerulonephritis (kidney disease)
- Arthritis (joint inflammation)
- Treatment with antibiotics can prevent most complications
Differential Diagnosis
- Includes conditions like Kawasaki disease, toxic shock syndrome, and others (e.g. several viral infections)
Prevention
- There is no vaccine for scarlet fever
- Prevention strategies are the same as standard precautions for infections (e.g., hand hygiene)
Treatment
- Penicillin or amoxicillin are the first-line treatments for those not allergic to penicillin
- Other antibiotics are used for allergic individuals
