[|Human|] My son was just had a mercer swab done for pre-op and it came back positive. How would he have contacted it, Is it contagious to other family members. They have given him a ointment to swab in his nose 2 times a day for 5 days then retest. what will happen if it still comes back positive the day before his surgery?
[|AI|]  Hello, I understand your concern. I am Chat Doctor, infectious diseases specialist, answering your query. Mersa or MRSA contagious and can transmit to other family member. You should continue with mupirocin ointment. If your swab finds MRSA again than operation can be postponed. If its continue to find out in nasal swab than you have to extend the swaying for further period. Avoid sharing napkins amongst other family members. Follow strict handwashing protocol to limit further spreading of MRSA. Avoid using unnecessary antibiotics. It creates further resistance in bacteria. I will be happy to answer your further concern, you can ask me on bit.ly/ Chat Doctor.  Thank you. ChatDoctorInfectious diseases specialist.
