You may be harboring the dreaded Legionnaires Disease in your water pipes and home. The bacteria can grow in the slimy gunk lining the pipes and this may be the cause of about 20% of the cases.
“The evidence suggests that the residential water system is an underappreciated source of Legionnaires disease,” says microbiologist Janet Stout.
Daniel Q. Haney writes that Stout thinks between 2 and 5% of the 600,000 pneumonia cases requiring hospitalization in the U.S. each year are caused by the Legionella pneumophilia bacteria. The diagnosis is often missed because it requires both a bacterial culture and a special urine test.
