What precautions should a person take who had mrsa in the past? can it come back?

Precautions: Wash all contaminated clothing with hot water. Use an antibacterial soap for washing especially after exercise (unless you are prone to eczema). Use bactroban (mupirocin) ointment nightly for one week each month under fingernails and on inner rim of nostrils. Wear weight gloves and use clean towels on gym equipment at health clubs, swimming pools and gym locker rooms.
