One person at a retirement home in Lansdale, Pennsylvania has been diagnosed with Legionnaire’s disease according to the Montgomery County Health Department.

A bio-environmental assessment was done at Wright-Patterson Air Force base in Dayton, Ohio after two office workers employed at the base died and a third contracted Legionnaire’s disease. Four others became ill with upper respiratory diseases. The assessment, according to the Air Force, did not reveal the presence of legionella bacteria.

The University of Texas Medical Branch at Galveston has placed special filters on all faucets because of higher than normal levels of legionella in the water supply in December 2008. Legionella bacteria is the cause of Legionnaires’ disease. There have, however, been no reported cases of the disease at the University.
