Based on information of SARS, Middle East respiratory syndrome (MERS), and COVID-19, the components of the epidemic (the sources, the routes of infection, and the susceptible population) will be discussed, as well as the role of natural and social factors involved. S ince the end of 2019, a novel coronavirus, namely severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID19) , appeared in Wuhan, Hubei Province, China. Recent results showed that SARS-CoV-2 persists longer with a higher viral load and peaks later in the respiratory tissue of patients with severe disease; this phenomenon highlights the need for the prevention and control of the epidemic. Some experts commented that people with mild or asymptomatic SARS-CoV-2 infection were not identified by epidemic prevention measures, thus accelerating the spread of the disease.	./cache/cord-268065-mxvbbkc4.txt	./txt/cord-268065-mxvbbkc4.txt
