Chickenpox is a highly contagious infection caused by the varicella-zoster virus, with fever and itchy blisters at different stages. A healthy child usually recovers without specific treatment, but a young baby, pregnant person, adult or someone with weakened immunity can become seriously ill and needs early assessment by telephone.
- Itchy red spots that become bumps, blisters and then scabs, while new spots keep appearing.
- Fever, tiredness, reduced appetite, headache or feeling out of sorts around the start of the rash.
- Offer drinks regularly and monitor urination, alertness and breathing; offer cool, soothing drinks and soft food for mouth blisters.
- Keep nails short, wash hands, discourage a child from scratching and use loose, breathable clothing to limit skin damage.
- Call the same day in pregnancy, for a young baby, weakened immunity or use of strong immunosuppressive medicines.
- For urgent GP care outside normal opening hours, call HAP 9252. Call Ambulance 912 only for an immediately life-threatening situation.
