MRSA stands for Methicillin-resistant Staphylococcus aureus. It is a form of bacteria that is responsible for infections in humans. The word is actually Airborne MRSA. It is not a disease itself but it is one of the many modes of transmission of this infection. Airborne MRSA is a new concept about the spread of the disease according to which MRSA can be spread through the air. This is because the bacteria is usually found on the skin of patients and skin cells are replaced after 30 days. This shedding of skin can result in millions of skin cells in the air and if you have the infection, it will spread with the skin cells, causing someone else to suffer.
