The Social Epidemiology of the new pandemic world

Abstract

From 2020, the Covid-19 Pandemic had lasted more than 2 years. In order to control and prevent the spread of viruses and variants, different countries adopt quite different policies. In Europe and north America, vaccination towards community immunity or herd immunity is the main concern and aim. So, these countries' policies to control the pandemic centers on emphasizing the cure and vaccine with the maximum freedom for their people and minimum impact on their economy and livelihood. The opposite of this kind of western anti-pandemic mode is the motion and endeavor which are trying to block the spread chain of the virus, mainly in China, North Korea and some other Asian nations. With the elapse of time, we will need to explore the effects of the different kinds of polices applying a diversity of methodologies, including case studies, especially undertaken from the local governance perspective and their intervention on anti-virus controls( Wu Ying and Ge Daoshun, 2020).
 Through digital technology, central and local governments are now empowered for the governance of pandemic control and, in fact, for any other event that may be presented as a threat to Public Health. This is a new Era of health systems intervention in contemporary societies. Studies on how these tools are applied and the functions of healthcare that are changing are a research priority.
 Meanwhile, the most vulnerable group under the threat of Covid-19 virus is the aged population. A better understanding on the physical and mental health of old people is now also crucial topics for generating evidence on the double background of pandemic outbreak and the aging society worldwide. Combination of 1ualitative and quantitative studies on these topics is required (Friedman, Mateu-Gelabert, Nikolopoulos et al, 2021). A new role for Social Epidemiology.
