The COVID-19 pandemic and the potential treatment of the novel coronavirus SARS-CoV-2

Coronavirus SARS-CoV-2 is a novel coronavirus and the seventh that can infect human beings and result in severe and acute respiratory syndrome and deaths. Currently, the world is undergoing a global health emergency due to the SARS-CoV-2 pandemic. As of May 18, SARS-CoV-2 has spread to over two hundred countries and infected more than 4.8 million people, resulting in over 300,000 deaths since the first case of a novel pneumonia (COVID-19) patient was discovered in Wuhan, China at the end of December 2019. Currently, there are no effective and/or approved targeting drugs for it though various supportive therapy drugs such as small molecule drugs, vaccines, antibodies and even Chinese herb medicines have been used in the treatment of the first-line patients. However, certain drugs such as remdesivir and S416 are under clinical investigation and may become therapeutic drugs. In this article, we review and discuss SARS-CoV-2, its person-to-person transmission, genomics and proteomics, and the potential for drug development.
