What is mrsa , why does it pose serious health risks especially for a health care professional and how is antibiotic resistance an example of evolution

MRSA is a infection, it can be spread very easily, especially in hospitals. Posing a health risk for health care workers. So antibiotic resistance is a huge step of evolution because their bodies can fight the infection but the health care workers can continue to do their jobs without worrying about this infection. MRSA stands for methicillin-resistant Staphylococcus aureus.
