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. Here is surface representation Here is cartoon represenation A video (by Elara Systems) shows how the virus interacts with its human (host) cell, via its spikes (whose 3D structure was determined in the McLellan Lab), thus permitting the viral genome to enter its host & begin infection. Details of the 3D structure & function of the key proteins & RNA inside the virus can be seen in the NY Times Bad News Wrapped in Protein: Inside the Coronavirus Genome.

Coronavirus Evolved Naturally, and ‘Is Not a Laboratory Construct,’ in a study in Nature Med by Anderson and colleagues . Scientists are endeavoring to find antivirals specific to the virus. Several drugs such as chloroquine, arbidol, remdesivir & favipiravir are undergoing trials to test their efficacy & safety in the treatment of COVID-19 in China, with some promising results.. A computer game, developed at the Inst for Protein Design (Univ Washington), is being used to try to find new lead compounds that might become drugs to treat COVID-19.
