Thin-section electron micrographs of the 2019 novel coronavirus grown in cells at The University of Hong Kong. The image shows part of a virus infected cell grown in culture with multiple virus particles being released from the cell surface. Each infected cell produces thousands of new infectious virus particles which can go on to infect new cells.
