Legionella bacteria found in Beaverton apartment complex hot tub
Washington County public health officials say they have not yet pinpointed the source of a recent Legionnaires' disease outbreak in Beaverton, but they have found the legionella bacteria that causes pneumonia in an apartment complex hot tub
Property owners have already drained the water as a precautionary measure, officials said. So if the hot tub is indeed the source of the outbreak, it is no longer a threat.
Six cases of Legionnaires' disease in the Murrayhill area of Beaverton, officials reported on Thursday, Oct. 28. No new cases have been reported since.
"Regular maintenance of hot tubs is important to prevent legionella and other infection-causing bacteria from growing, said Washington County health officer Dr. Christina Baumann. This includes making sure filters are changed, tubs are cleaned frequently and that there is an appropriate chlorine concentration and pH level in the tub."
Legionnaires' disease is a waterborne bacteria that infects people's lungs, according to the Oregon Health Authority. The bacteria is common in Oregon, and it's often found in warm, wet areas like hot tubs, water tanks, large air conditioning, plumbing systems and other bodies of water, health officials said.
The bacteria that causes illness hasn't been found in any other water sources tested in the Murrayhill area, including Murrayhill Lake.
