A mild fever is usually the first sign, followed by painful red blisters.
Paracetamol is the only recommended treatment. But make sure that you provide plenty of liquids to prevent dehydration.
Please read this information from the Ministry of Health which covers symptoms, treatment and prevention. If you are unsure what to do please call Healthline 0800 611 116.
If your child has Foot, Hand & Mouth please keep them home from school until blisters have dried.
