Meta AnalysisOlfactory and gustatory dysfunction in COVID-19 patients: A meta-analysis study.
COVID-19, caused by a novel coronavirus, is a persistent global pandemic. It is crucial to examine existing reports to effectively summarize and characterize its clinical course. We used a large-scale meta-analysis to establish prevalence rates for loss of olfaction and gustation in COVID-19 positive patients. ⋯ The estimated rate of olfactory disorder in patients with COVID-19 was 61.0% (95% CI 44.0%-75.0%). Our meta-analysis demonstrated high rates of taste (49.0%) and smell (61.0%) disorders in patients with confirmed COVID-19. Results increase the power of recent reports-loss of olfactory and loss of gustation should now routinely be considered in the setting of COVID-19 infection.
