 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].
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 spikes (3D structure determined in the McLellan Lab (U of Texas, Austin)[2])) and Wrobel, Benton & Gamblin labs name="Wrobel" />,
(from the Crick Institute, London), thus permitting the viral genome to enter its host & begin infection.
Potential treatments for COVID-19
- Human trials begin on coronavirus vaccine developed by Univ of Queensland, Australia.
- Oxygen administration could be more important than pressurised air when treating the illness induced by SARS-CoV-2. Homology modeling & molecular docking suggests that SARS-CoV-2 reduces hemoglobin's capacity to carry oxygen, resulting in the respiratory syndrome [3].
- 27-Mar-2020 Science - Not wearing masks to protect against coronavirus is a big mistake, Dr. George Gao, Director General of the Chinese CDC says in Science.
- 23-Mar-2020 A USA, French & UK study identified 69 drugs to test against the coronavirus[4]. As reported in the NY Times.
Videos helping to explain COVID-19
The Czech Republic took the uncommon step of making wearing of masks mandatory in public spaces, prompting a grassroots effort to make masks, with wonderful results

- Coronavirus Evolved Naturally, and ‘Is Not a Laboratory Construct,’ in a study in Nature Med by Anderson and colleagues [6].
- 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.[7].
- 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.
SARS-CoV-2 virus proteins
The genome of the SARS-CoV-2 virus codes for 28 proteins:
Out of those, 19 have already been characterized structurally.
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.
