Mrsa Rash

My little girl was hit by a car in a body cast for a month. Recently, we discovered that she has developed MRSA (staphylococcus aureus). My little boy had diaper rash Alway. I wondered if I should worry about bumps on his butt or is it just another diaper rash. I was very attentive to my children are not taking baths together and everything after I was finished using it. Can someone please help?

When someone has a staph infection. it is usually one or the other perhaps a couple of bumps that resemble pimples. like white heads. if they are like that and they have a black dot in the middle and it hurts him very badly as if you were to touch it, it hurts, he staphylococcus if not, just another eruption of his problems. just in case if I disinfect the tub every time they take a bath in fact.
