On my experience with early warning of an imminent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak
Authors: Changqing Wang
Abstract:In recent years, a number of life-threatening human pathogens have emerged. A novel coronavirus-related disease, known as coronavirus disease 19 (COVID-19), was first reported in Wuhan, China. The pathogen of COVID-19 has been identified as SARS-CoV-2. SARS-CoV-2 proceeded to spread in China and around the world, reaching pandemic proportions. The COVID-19 outbreak has caused huge human casualties and serious economic losses, posing a global threat. The continued periodic emergence of the coronavirus poses a major threat to human health and the economy. Ironically, even after a decade of research on coronaviruses, there is still no licensed vaccine or therapeutic agent to treat coronavirus infection. This highlights the importance of early warning and preventive measures in public health agencies to prevent future pandemics. Here, I draw on media reports and expertise to sum up my experience prior to the widespread outbreak of SARS-CoV-2. I believe this can serve as a reference for the prevention of COVID-19 and an aid for control systems of public health agencies to improve epidemic monitoring and early warning.
