Volunteers who have been diagnosed/survivors of Legionnaire's Disease

Volunteers who are healthy.

This standardized test, the most widely used olfactory test in the world, is derived from basic psychological test measurement theory and focuses on the comparative ability of subjects to identify odorants at the suprathreshold level. The UPSIT consists of four envelope-sized booklets, each containing ten "scratch and sniff" odorants embedded in 10- 50-µm polymer microcapsules positioned on brown strips at the bottom of the pages of the booklets.

The number of correct odor identification responses out of 40 from the standardized University of Pennsylvania Smell Identification Test.

The total number of correct responses will then be compared to standard norms of correct responses based on demographic information such as age and sex. Comparing the scores to the standard norms collected will indicate whether a volunteer is normosmic, hyposmic, or anosmic.

These are various demographic and medical history questions regarding exposure to Legionella Pneumonia and current experiences post diagnosis and treatment.
