Why is there a distinction between people who get MRSA infection in the hospital and those who get it at home?

Methicillin-resistant staphylococcus aureus (MRS) infection can be either community-acquired (contracted anywhere outside of a hospital or clinical setting) or nosocomial (contracted in a hospital or similar setting). Community-acquired MRSA is becoming more and more common in our society. Many people have MRSA but don't know it because it's not causing any problems. However, if you have a weakened immune system or you are living with a chronic illness, like diabetes, you could end up becoming quite ill because of the infection.

Nosocomial infections are transmitted and contracted within the hospital. That means the patients are being exposed to the MRSA through visitors, staff, equipment, or other patients. In this setting, proper hand washing and sterilizing techniques would cut down on the spread of MRSA. Because people in the hospital are there because they are ill or injured, their body is stressed, making them more vulnerable to developing an infection if they're exposed. This makes the spread of MRSA very serious.
