Four additional cases of Legionnaires' disease have been reported at Covenant Living at the Holmstad in Batavia, Ill., bringing the number of confirmed cases to 12, according to an article on the Daily Herald website.
The senior living facility is working with the Kane County Health Department and the Illinois Department of Health to control potential Legionella bacteria.
Those interventions include adding microbial filters to shower heads in the health care area, flushing water fixtures biweekly in every apartment and common spaces, and doing chemical and mechanical cleaning of the cooling tower.
The facility is also taking an even more aggressive measure of potable water disinfection with hyperchlorination.
