Blockchain technology has an enormous scope to revamp the healthcare system in many ways as it improves the quality of healthcare by data sharing among all the participants, selective privacy and ensuring data safety. This paper explores the basics of blockchain, its applications, quality of experience and advantages in disease surveillance over the other widely used real-time and machine learning techniques. The other real-time surveillance systems lack scalability, security, interoperability, thus making blockchain as a choice for surveillance. Blockchain offers the capability of enhancing global health security and also can ensure the anonymity of patient data thereby aiding in healthcare research. The recent epidemics of re-emerging infections such as Ebola and Zika have raised many concerns regarding health security which resulted in strengthening the surveillance systems. We also discuss how blockchains can help in identifying the threats early and reporting them to health authorities for taking early preventive measures. Since the Global Health Security Agenda addresses global public health threats (both infectious and NCDs); strengthen the workforce and the systems; detect and respond rapidly and effectively to the disease threats; and elevate global health security as a priority. The blockchain has enormous potential to disrupt many current practices in traditional disease surveillance and health care research.

This article draws on the experience of disarmament, demobilization and reintegration (DDR) programs on the African continent. It explains the link between DDR in Africa and the evolution of post-conflict peacebuilding as envisioned by former UN Secretary General Boutros Boutros-Ghali, the phases of the DDR process, the actors involved in the practice of DDR—both within the UN system and outside. Seven case studies are used to illustrate how DDR programs have been implemented, the lessons that have been learned as a result, and the challenges that are yet to be overcome. A general evaluation of DDR is provided in the conclusion, which taps into discussions and recommendations emerging from a 2006 conference held on the subject at the Kofi Annan International Peacekeeping Training Centre (KAIPTC) in Accra, Ghana.

Background: Africa is facing the triple burden of communicable diseases, non-communicable diseases (NCDs), and nutritional disorders. Multilateral institutions, bilateral arrangements, and philanthropies have historically privileged economic development over health concerns. That focus has resulted in weak health systems and inadequate preparedness when there are outbreaks of diseases. This review aims to understand the politics of disease control in Africa and global health diplomacy’s (GHD’s) critical role. Methods: A literature review was done in Medline/PubMed, Web of Science, Scopus, Embase, and Google scholar search engines. Keywords included MeSH and common terms related to the topics: "Politics," "disease control," "epidemics/ endemics," and "global health diplomacy" in the "African" context. The resources also included reports of World Health Organization, United Nations and resolutions of the World Health Assembly (WHA). Results: African countries continue to struggle in their attempts to build health systems for disease control that are robust enough to tackle the frequent epidemics that plague the continent. The politics of disease control requires the crafting of cooperative partnerships to accommodate the divergent interests of multiple actors. Recent outbreaks of COVID-19 and Ebola had a significant impact on African economies. It is extremely important to prioritize health in the African development agendas. The African Union (AU) should leverage the momentum of the rise of GHD to (i) navigate the politics of global health governance in an interconnected world(ii) develop robust preparedness and disease response strategies to tackle emerging and reemerging disease epidemics in the region (iii) address the linkages between health and broader human security issues driven by climate change-induced food, water, and other insecurities (iv) mobilize resources and capacities to train health officials in the craft of diplomacy. Conclusion: The AU, Regional Economic Communities (RECs), and African Centres for Disease Control should harmonize their plans and strategies and align them towards a common goal that integrates health in African development agendas. The AU must innovatively harness the practice and tools of GHD towards developing the necessary partnerships with relevant actors in the global health arena to achieve the health targets of the Sustainable Development Goals.

There is no question that peace and health are inextricably linked. War affects human health through the direct violence of military arms and through the structural violence that leads to major interruptions of the socio-economic systems people use to address their health needs. Those disruptions are compounded by natural disasters and manifold vulnerabilities that force countries to divert economic resources from health services. Clearly war and violence are a public health concern. We argue here that not only can health be a bridge to peace, but as well, what the world is witnessing now is the emergence and growth of health diplomacy which can potentially become a robust medium for strengthening that nexus between health and peace.

Harvesting bank accounts is frighteningly easy. Millions of pounds are stolen each year, and the authorities seem powerless to prevent it. This article examines various methods used to obtain personal details from unsuspecting users. The methods considered include: phishing - an e-mail directing users to a counterfeit website; pharming - harvesting user details using malicious code installed on their machine; and DNS poisoning - hijacking of the domain name server to redirect the browser to sites other than that one displayed in the address bar. Countermeasures against these threats are discussed in each case.
