COVID-19 outbreak: An elusive enemy

A novel coronavirus, officially termed as severe acute respiratory syndrome (SARS)-CoV-2, emerged in Wuhan, China, toward the end of 2019. Just four months later, more than 100,000 people were diagnosed with COVID-19, the resulting disease. The genetic analysis of SARS-CoV-2 revealed that this virus is a new Betacoronavirus, closely related to bat-derived SARS-like coronaviruses. Clinical data from hospitals in China have revealed that approximately 10% of the infected patients have severe disease requiring intensive care. Since containment of the outbreak may have partially failed due to asymptomatic transmission, it is imperative to accelerate the development of rapid point-of-care diagnostic tests, vaccines, and therapeutics for the COVID-19 epidemic.
