MRSA: MRSA is an abbreviation for multiply resistant Staphylococcus Aureus, and is very infectious. There is a small chance it was transferred from a drinking cup, but the only way to know would be for you to have culture samples from your mouth and nose. The nasal passages are an area where this bacteria may frequently colonize and is a eay to detect if you may have MRSA colonization

I wouldn't worry: MRSA is everywhere in our environment. About 70% of the staph pustules tested show community acquired MRSA, so assume it is on the doorknobs you open or other surfaces you touch.If you then touch your face, it can move into your nasal passages and make you a carrier.Since this can come from almost anywhere, good hand washing is your best protection.Try not to make your friend feel like an outcast
