In this era of globalization, non-stop movements of humans and
goods make no country immune to the potential threat of epidemics.
Since 2003, emergent contagious diseases such as the avian
influenza, Middle East respiratory syndrome, SARS, and Ebola
reminded us human beings once and again of the grave threat that
they pose to the human health and the economic and social security.
While the spread of COVID-19 is gradually being contained in
China, the world is facing several new hot spots such as Japan,
South Korea, Iran, and Italy. So, dissemination of the knowledge and
know-hows of the prevention and control of the epidemic is urgent
and essential not only for China but also for the world.
