Symptoms and Precautions of Chickenpox in Children
Aug 07, 2026
Chickenpox is a highly contagious viral infection caused by the varicella-zoster virus. Although widespread vaccination has made it less common, it still affects many children in India each year. The infection is usually mild but can cause significant discomfort and, in some cases, complications. Recognising the early symptoms and following the right precautions can help parents care for their child safely at home while reducing the risk of infection among other family members.
If you notice symptoms that suggest chickenpox or are unsure about the diagnosis, consult with your pediatrician. For an accurate assessment and timely treatment, it is advisable to visit a child care hospital, especially if your child is very young, has a weakened immune system, or develops severe symptoms.
What is Chickenpox?
Chickenpox is a viral infection caused by the varicella-zoster virus, the same virus that causes shingles later in life. It spreads through direct contact with the rash or through respiratory droplets from an infected person. Once inside the body, the virus incubates for 10 to 21 days before symptoms appear. Most children develop lifelong immunity after having chickenpox once.Chickenpox in India
Comprehensive national data on the annual number of chickenpox cases in India are limited because many mild infections may be managed at home without being formally reported. However, outbreaks continue to occur across the country. A study published in 2024 reported approximately 74 chickenpox outbreaks in India during 2022. The National Centre for Disease Control also continued to list chickenpox among the main diseases associated with reported outbreaks in early 2026. These figures highlight the importance of recognising symptoms early, preventing transmission and discussing vaccination with a paediatrician.What are the first signs of chickenpox?
The earliest chickenpox symptoms often appear one to two days before the rash:- Mild to moderate fever (37.5 to 39°C)
- Feeling generally unwell or tired
- Headache and body ache
- Loss of appetite
- Mild sore throat or runny nose
Chickenpox Symptoms in Babies
Chickenpox symptoms in babies can look different from those in older children. Babies may show:- Fussiness or irritability
- Reduced feeding
- Small red spots on the scalp, face, or trunk
- Blisters that develop into scabs within a few days
How to Diagnose Chickenpox How is chicken Pox Diagnosed?
Chickenpox is usually diagnosed clinically based on the characteristic rash. It progresses through recognisable stages:- Small red spots (macules) appear on the trunk, face, and scalp
- Spots become raised bumps (papules) within hours
- Bumps develop into fluid-filled blisters (vesicles)
- Blisters break, crust over, and form scabs
If you notice symptoms that suggest chickenpox or are unsure about the diagnosis, consult with your pediatrician. For an accurate assessment and timely treatment, it is advisable to visit a child care hospital, especially if your child is very young, has a weakened immune system, or develops severe symptoms.
Precautions to Prevent the Spread of Chickenpox
- Keep the child at home until all blisters have crusted over (usually 5 to 7 days after the rash appears)
- Avoid contact with pregnant women, newborns, and immunocompromised individuals
- Wash hands frequently, especially before handling food
- Keep the child's fingernails short to prevent scratching
- Use separate towels, bedding, and utensils
- Consider the varicella vaccine for all family members not yet immune
Home Care and Comfort Tips
- Give paracetamol for fever (never aspirin, as it is linked to Reye syndrome)
- Use calamine lotion or a cool oatmeal bath to relieve itching
- Dress the child in loose, cotton clothes
- Encourage plenty of fluids
- Offer soft, easy-to-swallow foods if mouth ulcers develop
- Reassure the child and provide gentle activities to distract from itching
When to See a Doctor
Contact your pediatrician promptly if your child has:- Very high fever (above 39.5°C) or fever lasting more than 4 days
- Signs of skin infection (spreading redness, warmth, pus)
- Difficulty breathing, chest pain, or persistent cough
- Severe headache, stiff neck, or altered consciousness
- Dehydration signs such as reduced urination or dry mouth
- A baby under 3 months with chickenpox symptoms

How long is chickenpox contagious?
From about 1 to 2 days before the rash appears until all blisters have crusted over, usually 5 to 7 days after the rash starts.
Can my child go to school with chickenpox?
No. Keep your child at home until all blisters have fully crusted to prevent spreading the infection.
Is the chickenpox vaccine part of routine immunisation in India?
The varicella vaccine is recommended by paediatric societies in India, though it is not part of the government-provided universal immunisation programme. Most pediatricians offer it as an additional vaccine.
Can my child get chickenpox twice?
Rarely. Most children develop lifelong immunity after one infection, though the virus can reactivate later as shingles in adulthood.
When are chickenpox scabs no longer contagious?
Once all blisters have crusted into dry scabs, the child is no longer contagious and can return to school.
