Coronavirus (CoV) is a kind of zoonosis virus widely existing in nature. Since the outbreak of severe acute respiratory syndrome (SARS), the incidence of human CoV infections has increased, so as the severity of the infections. In particular, coronavirus disease 2019, which is still pandemic, has become a major public health issue of global concern. This review summarizes the classification, host of CoV and human diseases caused by CoV.
With the acceleration of population aging process, the dependency ratio of the elderly is gradually rising, the function of family care is weakening, and informal care presents an imbalance between supply and demand in China. More and more scholars have carried out studies on predicting the population size of disabled elderly, the intensity and cost of informal care in China, but there is a lack of systematic generalization. This study summarizes research methods and prediction content of informal care through literature research and comparative analysis, providing a basis for comprehensive demand prediction. Currently in China, researches on informal care focus on macrosimulation approach, with a deficit in comprehensive application of macrosimulation and microsimulation approach, and the involved models are not accurate enough. In terms of the prediction content, the researches are mainly devoted to the prediction of care cost but rarely to the prediction of care intensity and source. Therefore, future researches should concern with in-depth exploration of care intensity, care source and care cost, and comprehensively use macrosimulation and microsimulation approach to improve the accuracy and comprehensiveness of prediction models.
The coronavirus disease 2019 (COVID-19) pandemic is the most severe public health crisis in the past century. Improving the system and mechanisms of governance for major pandemic crisis is an important part of strengthening China′s governance system and capacity. This study analyzed present situation and weaknesses of China′s public health emergency management system and its mechanisms. Our results suggested that responses to major pandemic crisis should be extended from the traditional "emergency management" to "crisis governance", with a trinity of government, social and professional governance. The conceptual model of the system and mechanisms of governance for major pandemic crisis was constructed.
As an important part of the International Health Regulations, risk communication plays a significant role in the response and management of public health emergencies. Recommended by World Health Organization (WHO), the five principles for risk communication practice include building trust, releasing information timely, information transparency, paying attention to the public, and formulating preplan. In the study, we analyze and summarize the application of WHO′s five principles of risk communication in the management process of a health emergency response after a strong earthquake occurred in Maduo County, Guoluo Tibetan Autonomous Prefecture, Qinghai Province in May 2021 for providing a reference to prospective practice in future.
