My daughter has mrsa she has not had any symptoms in over a year but now her grandma's doctor says that my daughter gave her a regular staph infection?

Staph infection.: That is a possibility, especially if your daughter has open sores or impetigo of the skin. Another source of contamination would be a runny nose with a mucoid discharge.

Confusing question: People can have a MRSA infection but they don't carry it forever like hiv. Treatment eliminates the germ.Staph is present everywhere in the environment and more than 70% of the abscess i see are community acquired mrsa, while 30% are not. Her grandma could easily get staph from her environment, and why her doc accused your child of bringing it to her is beyond me.

Not likely: Mrsa is everywhere, on everything. It is not possible to say where grandma got it from. Maybe she gave it to your daughter a year ago. It is one of the most frequent skin infections we see in the office. We don't even try to figure out who gave it to whom.
