My daughter has a blister like nappy rash that has spread to her buttocks and her face and has a light rash all over her body. they look like blisters?

Diaper rash: I am not sure how old your daughter is, but with the history of blisters, I would be worried about a staph infection. She needs to see her pediatrician soon.

Viral exanthum: Rashes associated with fever in children are often caused by viral infections. We call these 'exanthums'. These rashes are generally harmless and go away when the infection resolves. However, rashes associated with very high fevers, lethargy, rapid progression, vomiting or other concerning symptom require immediate evaluation.

See your doctor: Depending on the age of your daughter, this may represent a viral rash that may need a complete exam for verification. Better to err on safety vs treating as a regular "diaper rash."

See your DR: Need exam to determine if virus, other infection, eczema, etc. You must indicate that it is URGENT when you call.

Dr Sia agreed

Blisters: Your daughter most likely has bullous staph which is an infection that causes blisters. Your daughter needs to be on oral antibiotics. Take your doctor for treatment and to make sure of the diagnosis.
