My father (who has myeloma/secondary PCL) came home from the hospital with an MRSA infection on his back.  It responded to antibiotics and cleared up, but he still has the bacteria in his nose.  Weve been practicing good handwashing and disinfecting surfaces.  This morning I woke with several mouth ulcers.  Could this be MRSA acquired somehow?  e.g., not using hot enough water to wash cutlery or something?  We dont share food.  I am also under a lot of stress, having been his solo caregiver through his cancer battle for the past 6 months.  Thank you, Doctor(s).
Hi & Welcome to Chat Doctor. I appreciate your concern for the MRSA infection. Yes, it is contagious infection, the bacteria (staphylococci) which are normally present in the nose can be transmitted by sneezing, coughing or shaking hands, direct contact with an infected wound or by sharing personal items, such as towels or razors, that have touched infected skin, etc. MRSA infection usually occurs in the skin with pus formation. Mouth ulcers are unlikely to have been caused by MRSA. Hope this answers your query. Best regards.
