MRSA symptoms

If you have been nursing a loved one who is MRSA positive it is important to disinfect the environment and follow a few simple rules to stop cross contamination.

Although MRSA is a serious bug, disinfecting your house will not take a great deal of effort.


But let’s start with the facts

What is MRSA? (methicillin-resistant Staphylococcus aureus)

It is a specific “staph” bacteria resistant to many types of antibiotic treatments. (Often called a super bug)

The Centers for Disease Control and Prevention (CDC) state that most infections appear as red, swollen pustules or boils that have pus or other drainage and are usually present where there are cuts or abrasions and in areas covered by hair.

In general, healthy people with no cuts, abrasions, or breaks on their skin are at low risk for getting infected.


MRSA Lifespan

  • MRSA can live for up to 7 months on dust
  • MRSA can live for up to 8 weeks on a mop head
  • MRSA can live for up to 9 weeks on a cotton towel
  • MRSA can live for up to 203 days (over 6 moths) on a blanket
  • MRSA can live on the skin of otherwise healthy individuals, with no symptoms indefinitely


On The Bright Side

In outbreaks of MRSA the environment has not played a significant role.

MRSA is most frequently transmitted via direct skin to skin contact, or contact with shared items or surfaces which have had contact with the infection, such as counter tops, dirty towels and used bandages etc.


How To Keep Yourself and Your Home Squeaky Clean and Disinfected

  • Frequently wash your hands with soap and water or an alcohol based hand wash
  • Cover all open wounds with a clean dry bandage until completely healed
  • Avoid sharing any personal item that may come into contact with the skin
  • Wipe down all hard surfaces with a bleach solution – 100ml of bleach in 3 liters of water
  • Wash any clothing that has come into contact with MRSA using your normal laundry detergent.
  • Drying clothes in a dryer instead of air drying them will also help kill bacteria in clothes
