Methicillin-resistant Staphylococcus aureus, commonly known as MRSA, is a type of bacteria that has developed resistance to many antibiotics, including methicillin. This makes infections caused by MRSA more difficult to treat compared to other strains of Staphylococcus aureus. MRSA is often found in healthcare settings but can also occur in the community. MRSA infections can lead to various health issues, ranging from skin infections to more severe conditions like pneumonia or bloodstream infections. Preventive measures include proper hand hygiene, wound care, and avoiding sharing personal items. Awareness and early detection are crucial for effective management of MRSA infections.
