SARS-CoV-2 infection of the oral cavity and saliva

The study titled “SARS-CoV-2 infection of the oral cavity and saliva” provides crucial insights into the role of the oral cavity in COVID-19 infection and transmission. Here’s a detailed summary: Background: Despite common oral symptoms in COVID-19, like taste loss, dry mouth, and mucosal lesions, the involvement of the oral cavity in COVID-19 has been poorly understood. This study aimed to address this gap by examining the human minor salivary glands and gingiva for signs of SARS-CoV-2 infection​​. Methodology: The study utilized two single-cell RNA sequencing datasets of the human minor salivary glands and gingiva, comprising 9 samples and 13,824…
