Most recent UW Medical Center patient with Legionella believed to have been exposed during an earlier hospitalization, according to an article on the UW Health Sciences News Beat website.
The patient likely was exposed prior to the discovery of the Legionella outbreak and before water restrictions and Legionella precautions were implemented.
The patient displayed symptoms suggestive of a Legionella infection on Sept. 18, two days after the second hospital admission. This means all of the exposure was prior to hyper-chlorination of the UWMC water system Sept.19-20.
Based on this information, water restrictions are not being reinstituted in UWMC's Cascade Tower. It is safe to drink and shower from filtered faucets and filtered showers in the inpatient units of the tower.
