Olfactory dysfunction in children is reported to be less prevalent than in adults, in general and specifically in COVID-19. Yet, olfactory testing is not widespread in the developing population and studies directly measuring smell loss in COVID-19 are sparse. Here we test whether the rapid smell test SCENTinel (version 2.0) can be used in a diverse group of youth to screen for olfactory dysfunction, and in particular COVID-19-associated olfactory dysfunction. A preliminary group of 178 youth (8-15 years old, mean±sd: 11.9±1.59, 58% girls, 65% white) completed the SCENTinel 2.0 test. Eighty-one participants (46% of the sample) received a COVID-19 lab test (8-15 years old, mean±sd: 11.9±1.7 years, 59% girls, 58% white), and N=6 (7%) tested positive (10-15 years old, mean±sd: 12.8±1.6 years, 83% White girls, 17% Non-white boys; days since COVID test range: 12-237 days, mean±sd: 110±79 days) and N = 75 (93%) tested negative (8-15 years old, mean±sd: 11.7±1.7, 25% white girls, 15% non-white girls, 31% white boys, 27% non-white boys; days since COVID test range: 0-493 days, mean±sd: 82±84 days). Although the accuracy for all subtests was nominally lower for the COVID+ group as compared to the COVID- group (detection: 17% vs 16%; intensity: 17% vs. 1%, identification: 17% vs. 13%), no comparison reached the significance level (lowest p = 0.34). Data collection is ongoing and a larger number of COVID+ participants is necessary to make robust statistical considerations. We however demonstrate that SCENTinel can be used in youth to assess olfactory function. This work is supported by NIH RADx-rad initiative U01DC019578.
