Welcome to HealthcareMagic forum.
I'm sorry that your dear daughter is down with flu. I appreciate your knowledge that a viral fever
could cause a rash , I see this as a likely cause in your daughters case also.This is called an exanthematous rash
which follows a viral fever.The acne
like bumps could be a secondary skin infection
or may be a minor skin change due to irritation around the nose and mouth.
If the temperature goes high, I suggest you to take the child to a pediatrician
to treat her symptomatically, hope she is eating well.give her good amount of fluids.
Wish her a speedy recovery
