The outbreak of a novel coronavirus (SARS-CoV-2) has resulted in a worldwide pandemic infecting over 5.9 million people [1].This positive-strand RNA virus can cause severe respiratory distress syndrome in humans (COVID-19), with over 364,000 deaths between December 2019 and May 30, 2020 [1,2].To combat this pandemic, the World Health Organization (WHO) is coordinating global efforts on surveillance, epidemiology, mathematical modeling, diagnostics, treatment and control, and has issued interim guidance to countries.Nevertheless, this is a difficult situation and the number of cases is rapidly increasing globally.The temporal evolution and the spatial spread of this virus have also raised serious concerns about the future trajectory of this outbreak.
