Scientists explained that cilia are a hair-like structure on the surface of airway epithelial cells that carry mucus and trapped viruses from the lungs.
Higher magnifications were used to show the structure and density of SARS-CoV-2 produced by the human airway epithelium.
According to researchers, these viral particles are a completely infectious form of virus released to the respiratory surface by infected host cells.
They said imaging studies help explain the incredibly large number of virions produced and released per cell in the human respiratory system.
According to scientists, the large viral burden is responsible for the spread of infection to multiple organs in infected individuals and may be responsible for the high frequency of COVID-19 infection to others.
They insist that infected and non-infected individuals use masks to limit SARS-CoV-2 infection, they said.
