Abstract:
In this study, we evaluated the relationship between surveillance data and COVID-19 pandemic, and the potential influencing factors for surveillance data by analyzing the characteristics, indicators, reporting time, and reported data of COVID-19 surveillance systems established by the WHO, Europe, United Kingdom, United States, Japan and China in the past three years. Surveillance data play a key role in pandemic response and control, which can not only give a full picture of the pandemic but also provide evidence for the timely evaluation of the effectiveness of prevention and control policies. However, surveillance data might be influenced by the difference surveillance systems in different countries. Therefore, in addition to the surveillance data, the information from multiple sources, such as the squeeze status of medical institutions and the excess mortality rate in the same period, should be analyzed to comprehensively understand the global pandemic and its harms to people.
