Chickenpox (Varicella) in children

    Chickenpox, also known as varicella, is a highly contagious viral infection caused by the varicella-zoster virus (VZV). It primarily affects children and is characterized by an itchy rash and flu-like symptoms. Here are key points to understand about chickenpox in children:


    • Chickenpox spreads through direct contact with an infected person’s rash, respiratory droplets, or by touching objects contaminated with the virus.
    • It is highly contagious, and infected individuals can transmit the virus even before they develop symptoms.


    • Chickenpox typically starts with flu-like symptoms, including fever, headache, and fatigue.
    • Within a day or two, a characteristic rash develops, consisting of red spots that progress into itchy, fluid-filled blisters.
    • The rash can appear on the face, scalp, trunk, and extremities, and it often spreads throughout the body.
    • Itching is a prominent symptom, and scratching the blisters can lead to secondary infections or scarring.


    • While chickenpox is usually a mild illness in healthy children, it can lead to complications, especially in certain groups:
      • Secondary bacterial skin infections.
      • Pneumonia.
      • Encephalitis (inflammation of the brain).
      • Varicella pneumonia (more common in adults).
    • Severe complications are more likely in infants, adolescents, adults, and individuals with weakened immune systems.


    • Diagnosis is typically based on the characteristic appearance of the rash and the presence of associated symptoms.
    • Lab tests may be performed in certain cases to confirm the diagnosis.


    • There is no specific antiviral treatment for chickenpox.
    • Management primarily involves relieving symptoms, such as fever and itching, with over-the-counter medications (under a doctor’s guidance) and keeping the child well-hydrated.
    • Calamine lotion and oatmeal baths can help soothe itching.
    • In severe cases or for individuals at higher risk of complications, antiviral medications like acyclovir may be prescribed.


    • Vaccination with the varicella vaccine is the most effective way to prevent chickenpox.
    • The vaccine is part of the routine childhood vaccination schedule in many countries.
    • Two doses of the vaccine are typically recommended.


    • Infected children should be isolated from others, especially those at high risk of complications, to prevent the spread of the virus.


    • Having chickenpox typically provides lifelong immunity against future infection with the varicella-zoster virus.

    Timing and School Attendance:

    • Children with chickenpox should stay home from school or daycare until they are no longer contagious, which is usually when all the blisters have crusted over.

    Chickenpox is a common childhood illness, and most children recover without complications. Vaccination has significantly reduced the incidence of chickenpox in many countries, but it is essential for parents and caregivers to be aware of the symptoms, practice good hygiene to prevent transmission, and seek medical advice if complications are suspected.
