Olfactory impairment is one of the more unique symptoms of COVID-19 infection and has therefore enjoyed increased public attention in recent months. Olfactory impairment has various implications and consequences ranging from difficulty detecting dangerous pathogens to hindering social functioning and social behaviors.

Evidence is divided into several categories representing potential mechanisms by which olfactory impairment can impact close social relationships bonding disruptions, decreased social support, missed group-eating experiences, hygiene concerns, and altered sexual behaviors.
