This is a time-lapse video of a cell-culture infected with the novel coronavirus. A single layer of kidney cells is visible at the start of the footage and slowly black dots appear across the cell sheet. The virus cannot be seen, but evidence of its presence can be, as infected cells which appear as black dots. As more cells become infected with virus they lift off the cell layer and appear as black dots. More and more infected cells become visible. The video footage starts following 40hrs of culture and finishes following 80hrs of incubation.
