Hello. MRSA can be quite contagious but you are already on 2 antibiotics, including the mupirocin, and should not be at significant risk of passing it on. That said, you would want to take normal precautions such as keeping the area of the wound covered and keeping your hands very clean, as they are usually the culprit in terms of transmission. In addition, you should check in regularly with your doctor to make sure the wound is healing (MRSA can be resistant to some antibiotics). You should also ask your doctor of you are carrying the bacteria in your nasal passages (a common source). If so, you may need to put mupirocin ointment in the nostrils to eradicate a potential source of future infection. Your doctor may want to swab your nose to look for nasal carriage of the MRSA.
