Initial Diagnosis Provided for Cases of Fatal and Nonfatal Inhalational Anthrax, Legionella Pneumonia, and Influenza A, and Family Physicians’ Responses to Clinical Case Vignettes

			Family Physicians’ Responses
Case No.	Type	Initial Diagnosis Reported ^3, ⁷	No.	Most Common Diagnosis	Second Most Common Diagnosis
Note: The first and second most common hypothetical diagnoses are provided. For summary categories, the total numbers of responses and top 3 hypothetical diagnoses are provided. The number of cases include 9 “anthrax” diagnoses and 7 cases for which the diagnosis was not listed.
FIA = fatal inhalational anthrax; CNS = central nervous system; CHF = congestive heart failure; NFIA = nonfatal inhalational anthrax; LEG = Legionella pneumonia; INF-A = influenza A; URI = upper respiratory infection.
* Initial diagnoses of inhalational anthrax were based on workplace exposure.
