76 yo mom has copd was unknowingly exposed to someone with mersa in the lungs yesterday. she washed her hands when leaving. should i be worried about her? she has no open sores on her hands.

MRSA: I think in general we would all say watch for any fever or change in her respiratory status but not to worry too much. She should be just fine.

No: Mrsa is not that easily spread by casual contact. If she becomes symptomatic- i would culture her sputum and treat with antibiotics if appropriate.

Watch for symptoms.: Mrsa is spread by contact but is not usually a problem unless the person is immune compromised. Watch for breathing difficulty or fever. Wash your hands and try not to worry it doesn't help.
