Can methicillin-resistant Staphylococcus aureus also called MRSA be spread through Blood or Blood Transfusions?
I suppose it is possible, but very unlikely. The sterility of all blood products is verified by multiple parties before they are issued and transfused. If a patient did develop septicemia (a blood infection) with MRSA post-transfsion, a contaminated line or non-sterile IV venipuncture would be a more likely cause than the actual blood product itself. The only way MRSA could be spread directly from person to person through blood (without transfusion) is if the blood originated from someone who had septicemia with MRSA in which case there would be no question they were ill.
