The major hypothesis is that a quantitative and unbiased smell test will be a useful tool to identify COVID-19 positive individuals.~The study will address what fraction of outpatients truly have a loss-of-smell (including a partial loss) and is expected to outperform the current question that is used to identify COVID-19 related anosmia Do you have a new loss of smell or taste? (yes/no) in terms of sensitivity and specificity.~The study will address if high-risk asymptomatic people whom are SARS-CoV-2 positive have a partial (or perhaps transitory) loss of smell.~The primary objective of this study is to validate the utility (sensitivity, specificity and accuracy) of a quantitative non-biased olfactory device for the rapid identification of SARS-CoV-2 infected subjects (as identified by PCR). The performance of the device will also be compared to the standard CDC patient query for 'new loss of smell or taste'.~The secondary objective is to test if SARS-CoV-2 positive 'asymptomatic' COVID-19 subjects may actually present with a mild or transitory defect in smell (hyposmia), which is revealed through our quantitative olfactory smell test.
The purpose of this study is to evaluate the performance of a non-invasive olfactory device as a rapid indicator of COVID-19 in positive subjects.
