MRSA is a strain of the Staphylococcus aureus bacteria, otherwise known as S. aureus, that’s resistant to methicillin antibiotics used against infections. Regular S. aureus is actually common – healthy people can have it on their skin or inside their noses. It’s when MRSA gets into a cut, catheter, or open wound and enters your bloodstream that an infection can get serious. Gone unchecked, it attacks the immune system and can lead to complications such as blood poisoning, pneumonia, organ failure and even death.
Though characterized as a flesh-eating #superbug, MRSA infections can start off as simple as a boil or pimple and can become an abscess, blister or sore.
