What did Germany do and why did it become an "excellent student against epidemic" in Europe?

Germany holds the rotating presidency of the European Union in the second half of this year. Many European public opinions are very concerned about how Germany, which can resist the popularity of COVID-19, unites the EU countries and escapes from the crisis together. German epidemic prevention is also facing many variables, but the German government's idea is clear: it must ensure the health of the people, reduce economic losses, and assume obligations to the European Union. From the financial crisis to the refugee crisis, and then to this global epidemic crisis, compared with other European and American countries, Germany once again demonstrated its ability to cope with the crisis. From the efficiency of the government, to the system design, to the strength of the whole country and the thinking of leaders, it has affected Germany's confidence in finally defeating the epidemic. Germany has created a record of the lowest proportion of infected people, the lowest mortality rate, the shortest response time and the least economic impact in Europe. These records reflect the effectiveness of Germany's decision-making and response to emergencies. After the outbreak of the epidemic in Bavaria and North Rhine-Westphalia in March, the federal and local governments cooperated and adopted a mild semi-sealed control scheme. According to the infection index published by the Institute of Virology, led by Chancellor Merkel, video conferences are held regularly to discuss the epidemic prevention plan. According to the actual situation, the state governments formulate different levels of epidemic prevention measures, and adjust them anytime and anywhere according to the changes of epidemic diseases. After the recent infection incident in the meat company factory caused a collective infection, Merkel immediately responded, reminding States not to neglect epidemic prevention to prevent a second outbreak of the epidemic. Since the spread of epidemic disease, German epidemic prevention measures have aroused widespread concern in the world, and soon realized the possibility of an outbreak in Covid-19, and strengthened nucleic acid detection. The most important factor to ensure the low mortality rate in Germany is large-scale nucleic acid detection, followed by a sound medical system. The mortality rate of infected people in Germany is one of the lowest in Europe, and it helps to accept infected people in Italy, which shows that Germany has a strong ability to cope with the crisis.
