This is an extremely difficult battle. In the past three years, China has effectively handled more than 100 cluster outbreaks, effectively protected the life safety and health of more than 1.4 billion people at the most ferocious stage of the virus, and the incidence, severity and death rates of COVID-19 are at the lowest level in the world. In the past three years, the virus has weakened and we have become stronger. With the acceleration of racing against the clock, we improved our ability to respond to the pandemic test, and the pathogenicity of COVID-19 declined. Adhere to border prevention and control, closely follow up the virus mutation, we have vaccines and drugs, improve our treatment ability, improve our epidemic prevention ability in peacetime and wartime, and improve our health awareness and literacy, which has laid the foundation and created conditions for further optimizing and improving the prevention and control measures. The meeting stressed that in accordance with the requirements of preventing epidemic, stabilizing economy and ensuring safe development, we should effectively coordinate epidemic prevention and control and economic and social development, protect people's life safety and health to the greatest extent, and minimize the impact of epidemic on economic and social development. We survived the hardest time! Putting people's life safety and health first is the primary consideration in formulating epidemic prevention and control policies in China, and also an important standard to measure the effectiveness of epidemic prevention and control. According to the latest data released by the World Health Organization, there are more than 641 million confirmed cases and more than 6.62 million deaths in COVID-19 worldwide. China has the lowest incidence rate of COVID-19 and the lowest death toll among the major countries in the world. Although there is a big gap between the per capita medical resources and the level of medical technology in developed countries, the per capita life expectancy has risen steadily, reaching 77.93 years in 2020 and 78.2 years in 2021. The Standing Committee of the Political Bureau of the CPC Central Committee and the Political Bureau of the CPC Central Committee have held meetings for many times to study and make decisions, and have led and organized the Party, government, military and civilian studies, and conferences and battles in the East, West, North, South, and Middle East; Establish a central leading group for epidemic response, dispatch a central guidance group, establish a joint prevention and control mechanism under the State Council... and quickly launch a people's war, a general war, and a war of resistance for epidemic prevention and control. It took about three months for China to achieve decisive results in the defense of Wuhan and Hubei, effectively curbing the large-scale spread of the epidemic and effectively changing the dangerous process of virus transmission. In 2021, the epidemic caused by Delta mutant once spread to more than 20 provinces. China quickly took preventive and control measures to effectively deal with more than 30 outbreaks. In 2022, the variation strains of Omicron will sweep the world. In March, the epidemic affected most provinces in China.
