Coronavirus Disease 2019 (COVID-19)

Overall view of the COVID-19 virus. Note the spikes blue that adorn the outer surface,red, which impart a corona like appearance. (Fusion Animation).

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 red, 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^[1]. An animation (by Elara Systems) shows how COVID-19 interacts with its host, via these spikes, thus permitting its genome to enter the host (human) cell^[1].

A USA, French UK study identified 69 drugs to test against the coronavirus^[2]. As reported in the New York Times (23-Mar-2020) "The researchers sought drugs that also latch onto the human proteins that the coronavirus seems to need to enter and replicate in human cells."

A French study^[3] showed, despite its small sample size (20 patients treated), that hydroxychloroquine treatment is significantly associated with viral load reduction/disappearance in COVID-19 patients and its effect is reinforced by azithromycin.

The CoV spike (S) glycoprotein is a key target for vaccines, therapeutic antibodies, and diagnostics. A study by McLellan and colleagues in "Science" on the Cryo-EM structure of the COVID-19 spike protein. This structure should greatly aid in the rapid development and evaluation of medical countermeasures to address the ongoing public health crisis^[1].

Scientists are endeavoring to find antivirals specific to the virus. Several drugs such as chloroquine, arbidol, remdesivir, and favipiravir are currently undergoing clinical studies to test their efficacy and safety in the treatment of COVID-19 in China, with some promising results summarized.^[8].
