Therefore, it is very important to study the development process of epidemics, which can provide useful materials for subsequent research. But up till now, few studies have summarized the whole development process, including some typical studies. Our work reviews some important events since the emergence of the first unknown pneumonia in December. In the first part, we studied the spread and development of COVID-19 from a macro perspective. In the second part, we focus on the specific processes and control measures of different countries, and select the four most representative countries, namely China, the United States, the United Kingdom and Italy. By these explanations of the spread process and national countermeasures of COVID-19, we can clearly understand the development of this epidemic.

In less than two months, the virus had spread all over the world. Temporarily, the whole world seems to be out of work. The epidemic situation was caused by a novel coronavirus named COVID-19. Before that, there had been a great number of infectious diseases caused by viruses, bacteria, parasites and so on, making the world suffer a lot. However, only COVID-19 emerged as a major public health emergency with the fastest spreading speed, the widest range of infection and the greatest difficulty in prevention and control. As the main battlefield of global epidemic prevention and control, China had done its utmost to prevent and avoid the spreading of the epidemic. Even so, the global epidemic situation had become worse and worse, and there were urgent needs to medical supplies in most countries. The WHO Director-General Tedros Adhanom Ghebreyesus said that COVID-19 was closer to causing a pandemic [1]. People around the world are deeply affected by the epidemic. First of all, a comprehensive outbreak in many countries will cause tens of millions of people to be infected. COVID-19 is destined to be a big disaster [2]. People in many countries are in need of living materials to survive the epidemic, resulting in a shortage of living resources. At the same time, the shortage of medical supplies also makes people panic. The masks, protective clothing and other resources of most countries are badly needed [3]. And in the USA, personal treatment costs tens of thousands of dollars. What’s worse, the world economy is suffering from a huge crisis. Unemployment rate is rising [4], prices are rising, production is falling and almost every people need to stay at home. The global economy is hard to recover in a short time. Take the Tokyo Olympic Games as an example. It has become the first modern Olympic Games in history to be postponed because of the epidemic [5]. This delay will not only cause heavy losses to Japan, but also cost IOC hundreds of millions of dollars. COVID-19 attacks humans with unprecedented scale and intensity. We are all witnesses of the epidemic. The crisis is changing the world, and countries are facing historic challenges to manage the crisis and build the future. Now every country in the world has taken positive measures，including postpone or cancel gathering activities, formulate the management regulations during the epidemic, suspend classes and schools, etc. Let's take a look at the responses of countries around the world under the epidemic situation. II. GLOBAL SITUATION OVERVIEW A. Global Situation Now COVID-19 has spread all over the world. In this part, we will comb the history of COVID-19 in the world. The onset time of first unknown pneumonia patient was presumed to be on December 1, 2019, in Wuhan, China [6]. On January 5, 2020, there were 59 new cases in China, after which a large-scale outbreak occurred in China.
