Revision of covid in China: A thorough analysis of epidemic situations and Chinese strategies during the pandemic

ABSTRACT

COVID-19, the disease caused by SARS-CoV-2, emerged in December 2019 in Wuhan, China, when Chinese authorities confirmed several patients with fever, difficulty breathing, and invasive lesions on the lungs. The virus then spread quickly across the globe, and by May 17, there were a total of 18,151,717 cases worldwide. While some countries still have an exponentially increasing rate of new cases, China has stabilized the spread of the virus. In the review of COVID-19 in this paper, we used sources from Google Scholar, PubMed, Research Gate, etc. In addition, when investigating public policy data and the number of infections, we also used the statements and relevant data from the official websites of the governments of Dalian and Beijing. Our investigation is based on the summary and analysis of the above data to reach our conclusion. We investigated the basic characteristics of COVID-19, the corresponding Sinovac vaccine and mRNA vaccine, the first round of outbreaks in Wuhan, Beijing, and Dalian, and the warning role of COVID-19 in the future. We demonstrated that keeping social distance and isolating infected patients in time can effectively block the transmission of the virus. This paper exposes the necessary public health measures during the pandemic, providing experiences and lessons for a potential future pandemic. © The Authors, published by EDP Sciences.
