Would 'smell tests' be more effective than fever checks to detect COVID-19?

The loss of smell or taste has emerged as a common symptom in patients with mild cases of COVID-19. About one-tenth of patients who complained of anosmia — the loss of smell — and dysgeusia — an altered sense of taste — reported the symptoms persisted or became even worse four weeks after they began, European researchers reported Thursday in JAMA Otolaryngology–Head & Neck Surgery. All reported the “sudden onset” of an altered sense of smell or taste two weeks before the initial swabs.
