{"title":"Early Warning Interventions for Environmental Risk Factors at China CDC.","authors":"Qinghua Sun,&nbsp;Chen Chen,&nbsp;Qing Wang,&nbsp;Tiantian Li","doi":"10.46234/ccdcw2023.125","DOIUrl":"https://doi.org/10.46234/ccdcw2023.125","url":null,"abstract":"President Xi Jinping emphasized the paramount importance of bolstering early surveillance and early warning capacities within a robust public health system (1). These elements constitute one of the five major functionalities of the National Bureau of Disease Control and Prevention (2). As an integral division of the National Bureau of Disease Control and Prevention, the Center for Disease Control and Prevention (CDC) is responsible for executing early surveillance and warning procedures in the realm of public health. Nonetheless, a deficiency persists concerning the early warning of public health risk factors. In 2019, the National Bureau of Disease Control and Prevention initiated nationwide pilots for environmental health risk assessment. Building upon these pilot studies, the National Institute of Environmental Health (NIEH) of China CDC embarked on research and development for early warning technology in environmental health risk. Utilizing factors such as air quality, heatwave, and cold-spell health risks as key areas of intervention, the NIEH undertook extensive research and development of suitable adaptive technologies. This was done through a systematic coordination of resources among all stakeholders, and exploration of effective mechanisms for health risk early warning interventions in public health. The NIEH has successfully integrated public health considerations into early warning systems for environmental risk factors, developing intricate, health risk-based warning and intervention technologies. These encompass air quality, heatwaves, and cold spellrelated health risk warnings. Building on this achievement, the NIEH has fervently promoted the early warning intervention through a pilot program on three fundamental aspects: technology research and development, platform construction, and mechanism development. Table 1 outlines the pilot program for health risk early warning initiatives related to air quality, heatwaves, and cold spells. In recognizing the significance of integrating early warning technology into health services, the NIEH facilitated early risk intervention strategies. This resulted in the pioneering fusion of medical and disease prevention sectors, giving birth to an innovative model for preventative disease control through early health warnings. Moreover, these developments offer a distinctively Chinese solution to global practices of early warning intervention.","PeriodicalId":9867,"journal":{"name":"China CDC Weekly","volume":"5 29","pages":"651-654"},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/05/2d/ccdcw-5-29-651.PMC10388181.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9926261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, these nations were critically deficient in their capacity for pathogenic testing and diagnostics, the availability of healthcare workers, and their supply of epidemic prevention materials, thereby impeding their ability to address the outbreak efficiently (2). This grave scenario underscored the need for support from the worldwide community. At the time, Sierra Leone lacked the domestic capacity for laboratory testing, including that of biosafety level 3 (BSL-3). Recognizing this constraint, the Chinese government hastily dispatched a mobile BSL-3 laboratory and corresponding technicians to Sierra Leone to facilitate testing within the country. Furthermore, the Chinese government expedited the establishment of the Sierra Leone-China Friendship Biosafety Laboratory (BSL-3) within a span of three months, observed to be operational by March 2015. It is important to note that this laboratory also conducted investigations centered on the detoxification of body fluids in Ebola survivors, fueling advancements in the understanding and management of the Ebola virus (3). The laboratory has played a significant role in the prevention and control measures during the Ebola epidemic. The Ebola outbreak in West Africa underscored a lack of ability to identify and diagnose emerging and re-emerging infectious diseases. While the outbreak has since ended, it underscored the necessity of strengthening the health system to better respond to future public health crises. This was underscored to the government and health practitioners. Sierra Leone, in particular, experienced a high mortality rate due to diseases such as malaria, pneumonia, diarrhea, cholera, Lassa fever, and measles. The nation continues to bear the brunt of public health crises, experiencing significant morbidity and mortality. Consistent international efforts are crucial to building the resilience and capacity of the public health system. To this end, China CDC, in collaboration with the Ministry of Health and Sanitation, Sierra Leone, implemented a multi-year capacity building program that incorporated laboratory operational capacity development and personnel capacity building (4). This article evaluates the performance and outcomes of this program (Table 1).","PeriodicalId":9867,"journal":{"name":"China CDC Weekly","volume":"5 28","pages":"632-636"},"PeriodicalIF":0.0,"publicationDate":"2023-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/df/35/ccdcw-5-28-632.PMC10372409.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9963908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Examining the Influence of Fertility Policy Adjustments on Gender Equality in China During the Period of Exceptionally Slow Population Growth.","authors":"Xueyan Yang,&nbsp;Wanxin Li,&nbsp;Rui Li","doi":"10.46234/ccdcw2023.116","DOIUrl":"https://doi.org/10.46234/ccdcw2023.116","url":null,"abstract":"The Chinese population is entering a new stage of development, marked by the fertility intentions of women of childbearing age continuing to decline and concerns over their consistently low fertility rates. The number of newborns has been decreasing annually, with 2022 figures falling below 10 million for the first time since the founding of the People’s Republic of China, resulting in negative population growth (1). Currently, China’s population over the age of 60 years is nearing 300 million and is projected to surpass 20% of the total population during the 14th Five-Year Plan period. Furthermore, the working-age population, estimated at 900 million in 2018, is expected to decline to approximately 830 million in 2030 and 700 million in 2050 (2). In response to the new stage of population development in China, adjusting fertility policy has become a priority to stabilize fertility levels, alleviate the pressure of aging, and promote supply-side reforms in population and labor fields. On November 15, 2013, the Central Committee of the Communist Party of China launched a restricted two-child policy, marking the relaxation of the Chinese government’s long-standing family planning policy, which was primarily focused on population control (3). On January 1, 2016, the Fifth Plenum of the 18th Central Committee of the Communist Party of China formally implemented the “universal two-child policy,” signaling a shift in China’s family planning policy from controlling population size to encouraging fertility intention and improving population quality (4). On May 31, 2021, the Political Bureau of the Communist Party of China Central Committee held a meeting to further optimize the fertility policy. This policy stipulates that a couple can have three children and outlines supporting measures, signifying the ongoing comprehensive adjustment and transformation of China’s fertility policy (5). Several scholars and practitioners have expressed concern about the potential impact of modifications to fertility policies on gender equality, as well as addressing the quantitative, structural, and qualitative challenges faced by population development. However, the underlying mechanisms of these challenges have not been sufficiently explored. In this study, we introduce the Dualistic Theory of Career-Family Life Cycle, examine the consequences of adjusting fertility policies on gender equality, and contend that the subsequent pressure will influence women’s careers and families. This change may raise women’s career thresholds, weaken women’s career persistence, and exacerbate women’s work-family conflicts. As a result, challenges to gender equality in China might arise, which could hinder the implementation of a threechild fertility policy.","PeriodicalId":9867,"journal":{"name":"China CDC Weekly","volume":"5 27","pages":"605-608"},"PeriodicalIF":0.0,"publicationDate":"2023-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/54/ab/ccdcw-5-27-605.PMC10354533.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9849478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
