The 2014/2015 West Africa Ebola epidemic has caused the global public health community to engage in difficult self-reflection. First, it must consider the part it played in relation to an important public health question: why did this epidemic take hold and spread in this unprecedented manner? Second, it must use the lessons learnt to answer the subsequent question: what can be done now to prevent further such outbreaks in the future? These questions remain relevant, even as scientists announce that the Guinea Phase III efficacy vaccine trial shows that rVSV-EBOV (Merck, Sharp & Dohme) is highly efficacious in individuals. This is a major breakthrough in the fight against Ebola virus disease (EVD). It does not replace but may be a powerful adjunct to current strategies of EVD management and control.
We contribute to the current self-reflection by presenting an analysis using a Primary Health Care (PHC) approach. This approach is appropriate as African countries in the region affected by EVD have recommitted themselves to PHC as a framework for organising health systems and the delivery of health services. The approach suggests that, in an epidemic made complex by weak pre-existing health systems, lack of trust in authorities and mobile populations, a broader approach is required to engage affected communities. In the medium-term health system development with attention to primary level services and community-based programmes to address the major disease burden of malaria, diarrhoeal disease, meningitis, tuberculosis and malnutrition is needed. This requires the development of local management and an investment in human resources for health. Crucially this has to be developed ahead of, and not in parallel with, future outbreaks. In the longer-term a commitment is required to address the underlying social determinants which make these countries so vulnerable, and limit their capacity to respond effectively to, epidemics such as EVD.
The PHC approach offers an insightful critique of the global and regional factors which have compromised the response of health systems in Guinea, Liberia and Sierra Leone as well as suggesting what a strengthened EVD response might involve in the short, medium and long-term.
2014/2015年西非埃博拉疫情促使全球公共卫生界进行深刻的自我反思。首先,必须思考自身在一个重要公共卫生问题上所扮演的角色:为何此次疫情会以如此前所未有的方式爆发并蔓延?其次,必须汲取经验教训,以回答后续问题:现在能采取什么措施来防止未来再次发生此类疫情?即便科学家宣布几内亚三期疗效疫苗试验表明rVSV-EBOV(默克公司)对个体具有高度有效性,这些问题依然具有现实意义。这是抗击埃博拉病毒病(EVD)的一项重大突破。它并非取代而是可能成为当前埃博拉病毒病管理与控制策略的有力辅助手段。
我们采用初级卫生保健(PHC)方法进行分析,为当前的自我反思做出贡献。鉴于受埃博拉病毒病影响地区的非洲国家已重新致力于将初级卫生保健作为组织卫生系统和提供卫生服务的框架,这种方法是恰当的。该方法表明,在因既有卫生系统薄弱、对当局缺乏信任以及人口流动而变得复杂的疫情中,需要采取更广泛的方法来让受影响社区参与进来。从中期来看,需要发展卫生系统,关注初级卫生服务以及基于社区的项目,以应对疟疾、腹泻病、脑膜炎、结核病和营养不良等主要疾病负担。这需要发展地方管理能力并投资于卫生人力资源。至关重要的是,这必须在未来疫情爆发之前而非与之同步进行。从长远来看,需要致力于解决那些使这些国家如此脆弱并限制其有效应对埃博拉病毒病等疫情能力的潜在社会决定因素。
初级卫生保健方法对损害几内亚、利比里亚和塞拉利昂卫生系统应对能力的全球和区域因素提供了深刻的批评,并提出了在短期、中期和长期加强埃博拉病毒病应对措施可能涉及的内容。
