MRSA is a contagious and antibiotic-resistant bacterium that can cause serious infections. Some common synonyms for MRSA include "methicillin-resistant Staphylococcus aureus," "multidrug-resistant Staphylococcus aureus," and "superbug." Other terms used to describe MRSA include "hospital-acquired MRSA" and "community-associated MRSA." MRSA infections can range from mild to life-threatening and can affect the skin, blood, lungs, and other organs. To prevent the spread of MRSA, it is essential to practice good hygiene, such as washing hands frequently, using hand sanitizers, avoiding close contact with infected individuals, and covering cuts and wounds. Treatment for MRSA typically involves a combination of antibiotics and other supportive therapies.
