LEFT: Overall view of the virus, showing the spikes in aqua.
RIGHT: Close up view of the spikes, from the McLellan Lab[1].
An animation shows how the virus interacts with its host, via its spikes, thus permitting the viral genome to enter the human (host) cell and begin infection (by Elara Systems).
Potential treatments for COVID-19
- 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.

Useful sites on COVID-19
- A summary of key findings about COVID-19 can be found at CDC.
- Coronavirus Evolved Naturally, and ‘Is Not a Laboratory Construct,’ in a study in Nature Med by Anderson and colleagues [4].
- 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.[5].
- Crowdfight COVID-19 - A scientific crowdsourcing initiative to put all available resources at the service of the fight against COVID-19
- A computer game, developed at the Inst for Protein Design (U Washington), uses crowdsourcing to try to find new lead compound that might become drugs to treat COVID-19.
