Majority of patients with mild Covid-19 experience altered smell/taste

In a separate study published online July 1 ahead of print in the journal Neuron, researcher Keiland Cooper, of the University of California, Irvine, and colleagues, explored possible mechanisms associated with smell and taste disturbance in Covid-19. They wrote that the high incidence of smell loss without significant rhinorrhea or nasal congestion in Covid-19 “suggests that SARS-CoV-2 targets the chemical senses through mechanisms distinct from those used by endemic coronaviruses or other common cold-causing agents.”
