Methicillin-Resistant Staphylococcus Aureus (MRSA) is a type of bacteria that has developed resistance to many antibiotics, including methicillin. It is commonly found on the skin and in the noses of healthy individuals but can cause serious infections, especially in those with weakened immune systems or open wounds. MRSA infections can occur in various settings, including hospitals and community environments. Symptoms may include redness, swelling, and pus at the infection site. Treatment options are limited, making prevention, such as proper hygiene and wound care, essential in controlling its spread.
