- | A novel coronavirus was identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China in 2019. The illness caused by this virus has been named coronavirus disease 2019 (COVID-19). The illustration (left) shows the overall structure of the COVID-19 virus. Note the spikes that adorn the outer surface, colored <span style="color:red">red</span>, which impart the look of a '''corona''' surrounding the virus. A close up view of these spikes can be seen on the right, from studies by McLellan lab<ref name="McLellan">PMID:32075877</ref>. An animation (by [http://elarasystems.com Elara Systems)] shows how [http://www.dropbox.com/s/24e5f5wdh64f5fv/ES_NL_CoronaVirus_Final.mp4?dl=0 COVID-19 interacts with its host], via these spikes, thus permitting its genome to enter the host (human) cell<ref name="McLellan" />.

SARS-CoV-2 virus. The spikes, that adorn the virus surface, impart a corona like appearance (Fusion Animation).
A novel coronavirus SARS-CoV-2, detected in Wuhan, China in 2019, was found to cause severe respiratory illness named COVID-19[1] (COrona VIrus Disease-2019).
There’s a new NCBI site on COVID-19/SARS-CoV-2. It will help bench scientists, bioinformaticians, clinicians & others connect with information they need to study SARS-CoV-2 and end the pandemic.
A video (by Elara) shows how the virus interacts with its human (host) cells, via its spike proteins[2][3][4][5][6][7], thus permitting the viral genome to enter its host & begin infection. The spike protein is induced for optimal binding when it is clipped by a protease (see animation on right side) and more details at SARS-CoV-2_protein_S_activation_by_furin. Subsequently, it undergoes a dramatic transformation to induce membrane fusion and infection, explained with a morph animation at SARS-CoV-2 spike protein fusion transformation.
