If the bacteria level in your urine is high and it’s causing physical symptoms, you have a symptomatic urinary tract infection (UTI).

How long does MRSA colonization last?
The patients included in these investigations (range, 52–135 participants) were identified as MRSA colonized through both targeted surveillance and incidental positive clinical culture results. In these studies, estimates of colonization half-life ranged from 7.4 months [8] to 40 months [4].
Is MRSA colonization permanent?
Eradication of MRSA carriage is not guaranteed or permanent. Thus, “decolonization” rather than “eradication” may be a more appropriate term. The effect of any eradication or decolonization strategy seems to last 90 days at most, although more prolonged follow-up has been infrequent.
How common is MRSA colonization?
MRSA is often resistant to other antibiotics, as well. While 33% of the population is colonized with staph (meaning that bacteria are present, but not causing an infection with staph), approximately 1% is colonized with MRSA.

You can be decolonised in hospital or at home.
Where does MRSA colonized in the human body?
MRSA colonisation growth of MRSA from a body fluid or swab from any body site. The most common site of colonisation is the anterior nares, but MRSA can also be found in other areas such as the axillae, abnormal skin (e.g., eczema, wounds), urine, rectum, and throat. There should be no signs or symptoms of infection.
