This computer-generated illustration shows the structure of the SARS-CoV-2 virus, which causes COVID-19. The virus is spherical, with a diameter of about 100 nanometers. The surface of the virus is covered with spikes, which are made of glycoproteins. These spikes allow the virus to attach to and infect cells. Inside the virus, there is a single-stranded RNA genome. The genome contains the instructions for making all of the proteins that the virus needs to survive and reproduce.
