Third Case Of Legionnaires' Reported

Another case of Legionnaires' disease has been reported in Southeast Michigan.

Health officials now say a third person has been diagnosed following a bacterial outbreak that affected at least 31 people at Selfridge National Guard Base in Harrison Township. 

The latest case involves a civilian employee at Warren-based TACOM, one of the Army's largest weapons developers.  At least one person -- a member of the Michigan National Guard -- is still in the hospital after being diagnosed with the disease. 

Two buildings, where officials believe the rare bacteria originated, were closed for sanitizing.

Legionnaires' disease is a type of pneumonia. The sometimes deadly disease takes its name from an outbreak at the Pennsylvania American Legion convention in Philadelphia in 1976.

An investigation is ongoing.
