Were you looking for information about MRSA (Methicillin-Resistant Staphylococcus Aureus) Infection? Merca infection is a common misspelling of MRSA infection.
Methicillin-resistant Staphylococcus aureus (MRSA) is a type of bacterial infection that is resistant to certain antibiotics. Over the past several decades, this illness has gone from being a controllable condition limited mostly to hospitals and healthcare facilities (such as nursing homes and dialysis centers) to a serious public health concern. It is estimated that up to 2 percent of the population in the community (and up to 7 percent of people in hospitals) is colonized with MRSA bacteria, either on the skin or in the nose.
It's important to note that symptoms do not always occur in people who are carriers of the bacteria. When symptoms emerge, they typically appear as a skin infection. One of the most common symptoms of MRSA is a red bump (or cluster of red bumps) that resembles a pimple, boil, or pustule.
