Our mission for loss of smell and loss of taste with u-Smell-it test

Why target smell? Our nose knows

Our nose is where viruses can enters and multiply, therefor wiping out one’s ability to smell.  For instance in Covid-19 the CDC has shown that loss of smell is as an early symptom that is better associated with Covid-19 than any other symptom. It was reported here that >80% of asymptomatic people have a partial loss of smell that can only be detected with a sensitive olfactory test.

Modelling shows an olfactory test could flatten the Covid curve

Modeled Impact and Cost of Oldfactory Dysfunction Testing

A modeling study showed that the simple olfactory test if used widely and frequently could have a dramatic effect on the number of people infected  with COVID-19. If used every 1-3 days an olfactory test such as u-Smell-it™ may even outperform a weekly PCR test, for a fraction of the price. Parameters that effect the performance are discussed in the paper.

Disclaimer: The founder of u-Smell-it (Dr. Toomre) was an author on the study, but the values used for the model are based on a wide body of published literature and the modelers have no affiliation with u-Smell-it™.
