Staphylococcus aureus is found throughout the human body. MRSA is particularly worrying, as it is resistant to strong antibiotics and can cause fatal infections when contracted in a hospital environment. MRSA prefers living in environments that are hot and wet, which is why it is commonly found in the nose. Both the Mayo Clinic and WebMD highlight that MRSA isn't usually problematic. However, if it enters the body through a cut, it can cause an infection that is hard to fight off.

WebMD suggests preventative measures, including regular hand washing, cleaning cuts, avoiding other people's wounds and paying close attention to personal hygiene when visiting hospitals, prisons and army bases.

MRSA is resistant to antibiotics as a result of antibiotic overuse. MRSA infections are more likely to affect those with weakened immune systems, which is why fatal infections often occur in hospital settings.
