What is the average Legionella positivity percentage in the domestic water system of the hospital over six sampling dates?

In assessing the average Legionella positivity percentage in the domestic water system of a hospital over six sampling dates, a rating of 45% indicates that nearly half of the samples tested positive for the presence of Legionella. This percentage reflects a significant prevalence of the bacteria in a controlled hospital environment. It is important for hospitals to maintain awareness of such levels, as they can directly impact patient safety and health.

A 45% positivity rate suggests that proactive measures are necessary for monitoring and managing water systems to mitigate the risks associated with Legionella, a pathogen that can cause severe respiratory illnesses. Regular testing, in conjunction with effective water management strategies, is essential for ensuring the safety of domestic water supplies within healthcare facilities.

In comparison to the other options, a 30% positivity might indicate lower risk and less immediate need for action, while 60% and 75% represent increasingly severe concerns that could necessitate urgent intervention and remediation procedures.
