Background

Coronaviruses are a family of viruses which cause various illnesses, including the common cold. In January 2020, a novel strain of coronavirus was identified in China. Since then, it has rapidly spread around the globe. The disease caused by the novel coronavirus, named COVID-19 by the World Health Organization, involves only mild symptoms (dry cough, fever) for most people who are infected (Sohrabi et al., 2020). However, some people with COVID-19 develop severe symptoms, and as of October 9, 2020, over 1 million people have been confirmed to have died of the disease (World Health Organization, 2020).
