The mouth and SARS-CoV-2: Evidence of infected cells suggests key role in infection, transmission

April 13, 2021 | News

BETHESDA, Md., U.S.: COVID-19 can cause a number of symptoms in the oral cavity, such as lesions, ulcerations and a loss of taste, and yet the role of the mouth in SARS-CoV-2 infection and transmission is poorly understood.
