Fifth Disease (Erythema Infectiosum): A Mom’s Quick Guide to Symptoms, Care & Prevention

Attention moms! Fifth Disease, also known as erythema infectiosum or “slapped-cheek” virus, is a common childhood illness. While it usually resolves on its own, knowing what to watch for and how to care for your child can bring peace of mind.

🔎 What Is Fifth Disease?

• Caused by parvovirus B19, fifth disease typically affects kids aged 5–15 but can occur in younger children or adults .
• It’s called slapped-cheek syndrome due to the bright red facial rash resembling sunburn or windburn .

⚠️ Common Symptoms to Watch For

1. Cold or flu-like first phase: mild fever, cough, runny nose, fatigue, muscle aches, headache
2. Distinctive red cheeks a few days into illness
3. Lacy pink rash spreading to arms and legs, sometimes itchy, especially after heat exposure
4. Mild joint aches in older children/adults—rare but possible

💡 Note: Many children have mild or no symptoms, making the rash often the first sign

🧑‍⚕️ When to Call the Doctor

Consult a pediatrician if your child has:

• Pregnant caregivers exposed during the first 20 weeks (risk of fetal anemia)
• Joint pain or high fever (>102°F)
• A blood disorder or weakened immune system

🩺 Treatment & At-Home Care

Most cases resolve with supportive care:

• Rest & hydration: Offer plenty of fluids like water, juice, or broth.
• Fever or discomfort?: Use age-appropriate acetaminophen or ibuprofen. Avoid aspirin in kids to prevent Reye’s Syndrome .
• For itching: Try lotions or antihistamines (like Claritin)
• Rash care: Oatmeal baths can relieve itching and soothe irritated skin

1. Frequent handwashing – after coughing, touching nasal secretions, or handling toys
2. Teach respiratory etiquette – cough into the elbow, not hands
3. Clean shared surfaces – disinfect doorknobs, toys, faucets regularly
4. No vaccine yet – prevention relies on hygiene and avoiding close contact while symptomatic

📅 Contagious Period & Childcare Guidelines

• Most contagious during the first week of cold-like symptoms, before the rash appears .
• Once the rash appears, contagiousness ends, meaning attendance in daycare or school is typically safe .

🎯 Quick Action Steps

1. Identify: Watch for red cheeks after flu symptoms.
2. Comfort care: Rest, fluids, OTC meds, oatmeal baths.
3. Stay vigilant: Monitor joint pain, high fever, or at-risk conditions.
4. Hygiene: Reinforce handwashing and surface cleaning.
5. School decisions: It’s okay to return after rash onset—check with your pediatrician.
