No association between COVID-19 and Guillain-Barré syndrome: study
by University College London 3D print of a spike protein of SARS-CoV-2, the virus that causes COVID-19–in front of a 3D print of a SARS-CoV-2 virus particle. The spike protein (foreground) enables the virus to enter and infect human cells. On the virus model, the virus surface (blue) is covered with spike proteins (red) that enable...
