Chickenpox
Chickenpox is a highly contagious viral infection that causes an itchy rash and flu-like symptoms. It is most common in children, but adults can also become infected, often with more severe symptoms. Most cases resolve on their own, but treatment focuses on relieving symptoms and preventing complications.
Quick Facts
- Caused by the varicella-zoster virus
- Spreads easily through respiratory droplets and contact with rash
- Most common in children
- Usually mild but can be more serious in adults and infants
- Vaccination helps prevent infection and reduces severity
Symptoms
Chickenpox symptoms usually develop in stages and may include:
- Itchy rash that turns into fluid-filled blisters
- Fever
- Fatigue
- Loss of appetite
- Headache
The rash often starts on the face, chest, or back and spreads to other parts of the body.
Causes
Chickenpox is caused by the varicella-zoster virus.
It spreads through:
- Coughing or sneezing
- Direct contact with fluid from blisters
- Contact with contaminated surfaces
A person is contagious before the rash appears and until all blisters have crusted over.
Risk Factors
You may be at higher risk if you:
- Have not been vaccinated
- Have not had chickenpox before
- Live or work in close-contact environments (schools, childcare)
- Have a weakened immune system
Treatments
At-Home Care
- Rest and hydration
- Calamine lotion or oatmeal baths for itching
- Keeping fingernails short to prevent scratching
Medications
- Fever reducers (avoid aspirin in children)
- Antiviral medications in certain cases
Prevention
- Chickenpox vaccine (varicella vaccine)
- Avoid contact with infected individuals
When to Seek Care
Contact a healthcare provider if:
- Symptoms are severe or worsening
- Fever is high or prolonged
- The rash becomes very painful or infected
- The patient is an adult, infant, pregnant, or immunocompromised
Seek urgent care if there are signs of breathing difficulty, confusion, or severe illness.
