Summary

The goal of this study is to determine whether survivors of Legionnaires' disease suffer smell loss. A quantitative olfactory test will be performed by the participants. Such testing will require approximately 20-30 minutes of the participant's time. The participants will take the University of Pennsylvania Smell Identification Test (UPSIT), a scratch-and-sniff test to assess their ability to identify odors in a forced- choice format. Volunteers will also complete a questionnaire asking personal history, demographic questions, and medical history.

Conditions

Interventions

OTHER

The University of Pennsylvania Smell Identification Test (UPSIT)

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.
