Red flags & when to go in person for Chickenpox (Varicella) - Triage

Audience: pediatric

Chickenpox (Varicella) is a common childhood illness that causes an itchy rash and fever. It usually gets better on its own without serious problems. However, some children may develop complications that need medical attention. This guide helps parents and caregivers recognize warning signs (red flags) that mean a child should be seen by a healthcare provider in person. Telemedicine can help assess mild cases and provide advice, but it cannot replace in-person care when symptoms are severe or complications arise. Knowing when to seek urgent care can keep your child safe and help manage chickenpox effectively.

Red flags — go in person / ER

• Difficulty breathing or rapid breathing — seek emergency care immediately.
• High fever lasting more than 4 days or over 39°C (102.2°F) — see a healthcare provider in person.
• Severe headache, stiff neck, confusion, or seizures — get urgent medical attention.

What telemedicine can do

• Assessment of mild chickenpox symptoms and rash via video or phone.
• Advice on symptom relief such as fever and itching management.
• Guidance on hydration and monitoring for complications.
• Education about chickenpox and prevention of spread.

What telemedicine cannot do

• Evaluation of severe symptoms such as difficulty breathing or seizures.
• Treatment of complications like skin infections or dehydration.
• Emergency interventions or hospitalization needs.
• Physical examination requiring hands-on assessment.

What is Chickenpox?

Chickenpox is a contagious viral infection that causes a red, itchy rash with small blisters. It often starts with fever, tiredness, and loss of appetite before the rash appears. The rash usually spreads over the body and goes through stages of blistering, bursting, and crusting over about a week. Most children recover without problems.

When to Use Telemedicine for Chickenpox

Telemedicine can be useful for mild chickenpox cases to get advice on symptom relief and watch for complications. You can show the rash and describe symptoms to a healthcare provider through video or phone. They can help you manage itching, fever, and hydration at home and decide if in-person care is needed.

FAQs

Can chickenpox be treated with antibiotics?

No, chickenpox is caused by a virus, so antibiotics, which treat bacterial infections, are not effective. Treatment focuses on relieving symptoms like itching and fever.

When is chickenpox contagious?

Chickenpox is contagious from about 1 to 2 days before the rash appears until all blisters have crusted over, usually about 5 to 7 days after the rash starts.

Is chickenpox dangerous for all children?

Most healthy children recover from chickenpox without problems. However, it can be more serious in babies, teenagers, adults, pregnant women, and people with weakened immune systems.

Can my child get chickenpox more than once?

It is uncommon but possible to get chickenpox more than once. Usually, after infection, the body develops immunity.

Should I give aspirin to a child with chickenpox?

No, aspirin should be avoided in children with chickenpox because it can cause a rare but serious condition called Reye's syndrome.
