Staphylococcus aureus is a bug that about 30% of us carry on our skin or in our noses. It is spread by direct skin-to-skin contact, which is why hand washing is so important. Most types of staphylococcus aureus do not cause any problems or can easily be treated with antibiotics.
MRSA is short for methicillin-resistant staphylococcus aureus. This is a bug that has become resistant to some standard types of antibiotic. It can cause problems if someone has had an operation or other treatment that breaks the skin. This is because MRSA germs can then get inside the body and cause an infection. It is not a stronger or more infectious bacteria than others.
If your baby becomes infected with MRSA, he or she may need to have an antibiotic pumped into his or her bloodstream. Vancomycin is an antibiotic that is commonly used to treat MRSA.
