Objective:The recent population census showed China had officially become a graying society.In the meantime,China also faces a growing burden of non-communicable diseases.Since 2009,a series of policies have been implemented to enhance primary care at the community level.This study describes the elderly care services provided in the differently organized community health centers(CHCs).Methods:It covered 13 CHCs of six cities located within the Pearl River Delta(PRD)region.In-depth interviews were conducted with a total of 59 health administrators,CHC managers,and CHC doctors regarding elderly care.Results:The study found that accessibility of healthcare for elders has been improved due to the development of health insurance schemes as well as preferential policy to encourage the CHC utilization by the elderly.All the CHCs provide health examinations and chronic disease management to the permanent elderly within their catchment district.However,some preventative care such as fall prevention,immunization and mental health management are not provided.Conclusion:Key barriers include low capacity of health service providers in the CHCs,and a lack of government investment in CHCs.Our report provides an empirical evidence for the health care reform in China. 展开更多

Summary What is already known about this topic?During the coronavirus disease 2019(COVID-19)pandemic,tremendous efforts have been made in countries to suppress epidemic peaks and strengthen hospital services to avoid hospital strain and ultimately reduce the risk of death from COVID-19.However,there is limited empirical evidence that hospital strain increases COVID-19 deaths. 展开更多

What is already known about this topic?After the initial coronavirus disease 2019(COVID-19)outbreak in Wuhan,China,the outbreaks during the dynamic-zero policy period in the mainland of China have not been systematically documented.What is added by this report?We summarized the characteristics of 74 imported COVID-19 outbreaks between March 19,2020 and December 31,2021.All outbreaks of early severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)variants were successfully contained with the aid of nucleic acid testing,modern communication technologies,and non-pharmacological interventions.What are the implications for public health practice?These findings provide us with confidence for the containment of future emerging infectious diseases alike at early stages to prevent pandemics or to win time to gain experience,develop vaccines and drugs,vaccinate people,and wait for the possible lessening of the virus’pathogenicity. 展开更多
