COVID-19 patients who reported smell loss as a symptom of their infection are ten times less likely to be hospitalized for coronavirus than those who do not report anosmia.
User data from a new COVID-19 symptom tracking app reveals a loss of taste and smell are the strongest predictors of a positive coronavirus diagnosis.
