B. Li (Illustration by B. McDowell) - Throughout the course of history human beings have continuously deepened their understanding of various viruses and serious diseases. Medical research has continued to improve, medical treatment has been continuously improved, medical equipment has been upgraded, public health emergency systems have been improved, and international cooperation has also been deepened in the fight against pandemics.
This time the world faces a new challenge as the corona virus has infected more than 1.2 million people worldwide. An outbreak of this size has a huge impact on the economic and public health systems of countries all around the world.
Looking back at history, from the "Black Death" in Europe in the 14th century to the Spanish flu in the early 20th century, human society has been threatened by various epidemics. In particular, the spread of several major epidemics in the past few centuries around the world has posed a serious threat to human health and safety.
However, human society is also constantly accumulating experience in the fight against these epidemics. In the past 20 years, in the face of SARS, H7N9, H1N1 influenza, MERS, Ebola and other epidemics, human beings have constantly deepened their understanding of various viruses and serious diseases in the struggle. Medical research has continued to progress and the level of medical treatment has continued to improve. With the replacement of medical equipment, public health emergency systems are becoming more and more efficient at handling outbreaks. We have also seen an increase in international cooperation.
In fact, humanity's battle against infectious diseases has no end. With the development of medical technology and the strengthening of international cooperation, the ability of human beings to cope with the spread of infectious diseases continues to increase. However, the acceleration of virus mutations and frequency of interpersonal contact have brought new challenges to the prevention and treatment of infectious diseases. Therefore, it is important to draw on the experiences of various countries, face the reality of how infectious diseases spread, and embrace scientifically-proven effective prevention and control methods.
