Nakagawara K, Masaki K, Uwamino Y, et al. Acute Onset Olfactory/Taste Disorders are Associated with a High Viral Burden in Mild or Asymptomatic SARS-CoV-2 Infections [published online ahead of print, 2020 Jul 26]. Int J Infect Dis. 2020;S1201-9712(20)30578-6. doi:10.1016/j.ijid.2020.07.034
We investigated the association between symptoms and viral clearance in 57 patients with asymptomatic/mild SARS-CoV-2 infection using cycle threshold (Ct) qPCR values. Patients with olfactory/taste disorders (OTDs) exhibited lower qPCR Ct values and longer time to negative qPCR than those without OTDs, suggesting association between OTDs and high viral burden.
