Chickenpox is a highly contagious viral disease caused by the varicella-zoster virus. Someone with chickenpox will usually have a high temperature and an itchy rash with red blisters. It is a common disease and mostly affects children.

What to look for

  • • red spots that can appear anywhere on the body and become itchy, fluid-filled blisters, which may burst and scab over
  • • a high temperature above 37°C (98.6°F)
  • • general aches and pains
  • • loss of appetite

What you need to do

1. If someone has chickenpox, make sure they are comfortable.

2. Give them plenty of fluids to prevent dehydration.

  • • If the casualty is a child, you could give them an ice lolly to suck.

3. You can give the casualty the recommended dose of paracetamol for an adult or the recommended dose of paracetamol syrup for a child.

  • • Do not give aspirin to anyone under the age of 16.

4. If the blisters are very itchy, ask a pharmacist for advice about creams and antihistamines that can be used to help.

5. To prevent the casualty from itching, you can:

  • • trim their fingernails
  • • put socks on their hands at night
  • • dress them in loose clothing.

6. Monitor their level of response until they recover.

7. Seek medical advice, if:

  • • the blisters appear to be infected
  • • you’re worried that they are getting worse.
