What should you know about coxsackie virus rash?

Coxsackie viruses are a group of viruses that can cause hand, foot and mouth disease. The rash may look like small red spots or fluid-filled blisters, and it can appear on the palms, soles, fingers, toes, or elsewhere on the body. Mouth ulcers may make eating and drinking uncomfortable. The illness often settles as the immune system clears the virus, but appearance alone cannot confirm the cause; other rashes include contact dermatitis, heat rash, drug rash, and scabies.

Offer frequent fluids and softer, cooler foods if mouth sores hurt. Keep the skin clean, avoid picking blisters, and use separate towels, cups, and cutlery. Regular handwashing after toileting or changing nappies helps reduce spread. Stay away from close contact while fever or unwellness is present, following local school or childcare advice. Do not give medicines or apply products to a child without checking the age guidance and a pharmacist or clinician.

Arrange prompt medical advice if the person cannot drink, is passing very little urine, seems unusually sleepy, has breathing difficulty, develops severe headache or neck stiffness, or has a rapidly worsening rash. Seek urgent help for signs of dehydration or a serious allergic reaction such as facial swelling or trouble breathing. A clinician should also review a rash in a very young baby, a person with a weakened immune system, or anyone whose fever persists or returns.

Could this rash be hand, foot and mouth disease or another infection? How can we keep drinking and eating comfortable? When is it safe to return to school, nursery, or work? Which symptoms would mean the illness needs urgent review?
