MRSA is a strain of staph bacteria that is resistant to antibiotics currently used to combat staph infections. People who work in hospitals, prisons and other places where there is a lot of interpersonal contact are likely to catch it. It can cause boils on the skin and it can also complicate invasive surgery.
Although there are currently available combinations of antibiotics that can combat this bacteria, it is by nature an adaptive creature and it is unknown how long current treatments will remain effective against it.
Once it is discovered that you are infected, you will need to alert medical personnel whenever you are admitted to a hospital and they will post a red sign outside your area. They will also don protective gear before entering your area or touching you.
I am posting this article after reading on Scientific American that living near pig farms, or fields that have been fertilized with unsterilized pig feces puts you at high risk for contracting this bacteria. While my dream is to one day run a farm, I do not intend to raise livestock for consumption.
If you start getting boils like this, immediately apply triple-antibiotic with a bandage to the effected area and see a physician for testing.
