An infectious disease, caused by a novel coronavirus, emerged in Wuhan City, China. The disease was later named coronavirus disease 2019 (COVID-19) and the virus causing it was named the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The rapid spread of COVID-19 worldwide has brought great challenges to local and global public health security and health systems. On March 12, 2020, the World Health Organization (WHO) declared the coronavirus outbreak a global pandemic and raised the risk of a global SARS-CoV-2 outbreak to “very high” (1-6).
