Can you have MRSA an not know it?

Yes, it is possible to have MRSA and not know it. This is because MRSA can colonize the skin or mucous membranes without causing any symptoms. This is known as asymptomatic colonization or carriage. People who are colonized with MRSA can still spread the bacteria to others, even if they do not have any symptoms themselves.

MRSA colonization is more common in certain groups of people, including:

* Healthcare workers

* People who have been hospitalized

* People who live in long-term care facilities

* People who have weakened immune systems

* People who inject drugs

* People who have skin injuries or infections

If you think you may be colonized with MRSA, it is important to talk to your doctor. They can test you for MRSA and recommend precautions to prevent spreading the bacteria to others.
