Description
Legionella (Reference #7)
this first iteration of the EPI program. Because it is not yet approved, the 
newer test of Legionella urinary antigen will not be used either. The Selected
Etiology screen display has been partially pre-populated.


     Since the American Legion Convention in Philadelphia in the 1970s, 
Legionnaires Disease has been an illness of keen interest to the DVA. Because 
diagnosis is complex, we have chosen to review for presence of Legionella in 
culture and in ICD DIAGNOSIS file (#80). We will not look at Legionella 
direct fluorescent antibody positivity because of the potential high false 
positivity of this test. Likewise, serology is not easy to interpret or easily 
extracted from VISTA for our purposes and will not be included as a marker in
