SARS-CoV-2 droplet deposition path and its effects on the human upper airway in the oral inhalation.

Background And Objective: It is crucial to study the uptake of viral droplets in the human respiratory system to control, prevent, and treat diseases.

Methods: In this study, a well-verified real anatomical model was used; the passage of air in the human upper respiratory system computed using high-quality Computer Tomography (CT) images. Then, the airflow field, along with the coronavirus micro-droplets injection, was examined in this realistic model using the Fluid-Structure Interaction (FSI) method.
