Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. First of all you should treat MRSA infection as such. Once the treatment is completed we can clear up the MRSA bug with mupirocin ointment. Mupirocin can be applied in the nasal septum, umbilicus, groin and axilla. This is the area where carrier MRSA resides. Once the area treated for appropriate period we can swab the area for the MRSA. If it comes negative for three successive occasion than we can declare you MRSA bug free. Please maintain good hygiene as it can also help combat the infection as antibiotics do. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
