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.

Contemporary infectious disease surveillance systems aim to employ the speed and scope of big data in an attempt to provide global health security. Both shifts - the perception of health problems through the framework of global health security and the corresponding technological approaches – imply epistemological changes, methodological ambivalences as well as manifold societal effects. Bringing current findings from social sciences and public health praxis into a dialogue, this conversation style contribution points out several broader implications of changing disease surveillance. The conversation covers epidemiological issues such as the shift from expert knowledge to algorithmic knowledge, the securitization of global health, and the construction of new kinds of threats. Those developments are detailed and discussed in their impacts for health provision in a broader sense.

ObjectiveThe objective is to share the progress and challenges in the implementation of the District Health Information Software Version 2 (DHIS 2) as an electronic disease surveillance system platform in Guinea, West Africa, to inform Global Health Security Agenda efforts to strengthen real-time surveillance in low-resource settings.IntroductionThe West Africa Ebola outbreak of 2014-2016 demonstrated the importance of strong disease surveillance systems and the severe consequences of weak capacity to detect and respond to cases quickly. Challenges in the transmission and management of surveillance data were one factor that contributed to the delay in detecting and confirming the Ebola outbreak1. To help address this challenge, we have collaborated with the U.S. Centers for Disease Control and Prevention (CDC), the Ministry of Health (MOH) in Guinea, the World Health Organization and various partners to strengthen the disease surveillance system through the implementation of an electronic reporting system using an open source software tool, the District Health Information Software Version 2 (DHIS 2). These efforts are part of the Global Health Security Agenda objective to strengthen real-time surveillance2. This online system enables prefecture health offices to enter aggregate weekly disease reports from health facilities and for that information to be immediately accessible to designated staff at prefecture, regional and national levels.Incorporating DHIS 2 includes several advantages for the surveillance system. For one, the data is available in real time and can be analyzed quickly using built-in data analysis tools within DHIS 2 or exported to other analysis tools. In contrast, the existing system of reporting using Excel spreadsheets requires the MOH to manually compile spreadsheets from all the 38 prefectures to have case counts for the national level.For the individual case notification system, DHIS 2 enables a similar accessibility of information that does not exist with the current paper-based reporting system. Once a case notification form is completed in DHIS 2, the case-patient information is immediately accessible to the laboratories receiving specimens and conducting testing for case confirmation. The system is designed so that laboratories enter the date and time that a specimen is received, and any test results. The results are then immediately accessible to the reporting district and to the stakeholders involved including the National Health Security Agency and the Expanded Program on Vaccination. In addition, DHIS 2 can generate email and short message service (SMS) messages to notify concerned parties at critical junctures in the process, for example, when a laboratory result is available for a given case.MethodsThis presentation is based on review of project experience and documentation for a Global Health Security project in Guinea from 2015-2018. In addition, this includes a 2017 evaluation of the DHIS 2 pilot phase in two regions each having five prefectures.ResultsThe use of DHIS 2 for aggregate and individual case reports for disease surveillance was piloted in two regions in Guinea in 2017 for a period of six months. An evaluation of the pilot phase indicated strong capacity at the Prefecture Level to use the system for weekly aggregate disease reporting as evidenced by the high weekly reporting rates as well as an assessment of users’ capacities. Challenges observed during the pilot phase included weak follow-up and ownership by the national level MOH, weak adherence by the laboratories to enter data on the receipt and test results of laboratory samples, and individual case reports not filed in all cases. In addition, the lack of uniformity of common data elements on the forms across different diseases made analysis and data quality more challenging.Following the evaluation of the pilot phase the MOH directed that the system should be used for aggregate weekly reporting, however that the individual case reporting in DHIS 2 should wait until improvements could be made in the case report forms. Prefectures have used DHIS 2 for weekly aggregate disease reporting starting in January 2018. In addition, the MOH plans to implement electronic individual case reporting in DHIS 2 starting in October 2018.ConclusionsProgress to date includes nationwide use of DHIS 2 by all prefectures for the submission of weekly aggregate case reports. In addition, the new case report forms have been configured in DHIS 2 and a training of trainers has been conducted at the national level to begin the process of implementing the electronic case reporting nationwide.Challenges include the continuation of parallel weekly disease reporting in Excel for an extended period after adoption of DHIS 2 resulting in lower timeliness of weekly reports in DHIS 2 in some prefectures, weak use of the system for data analysis, building capacity within the Ministry of Health to maintain the system without outside assistance, sufficient resources to pay for internet access and power back-up (such as solar power) to enable the health offices to effectively use the system, weak data privacy and security procedures, and the need to strengthen management of the national DHIS 2 server.References1.

Abstract Background COVID-19 has hit the world in an unprecedented way causing serious repercussions on several aspects of our life. Multiple determinants have affected various nations’ level of success in their responses towards the pandemic. The Arab Levant region in the Middle East, notoriously known for repeated wars and conflicts, has been affected, similarly to other regions, by this pandemic. The combination of war, conflict, and a pandemic brings too much of a burden for any nation to handle. Methods A descriptive analysis of data obtained from the health departments of various Arab Levant Countries (ALC) was performed. ALC include Lebanon, Syria, Jordan, Iraq and Palestine. The data collected involves incidence, recovery rate, case fatality rate and number of tests performed per million population, Global Health Security index, government stringency index, and political stability index. The information obtained was compared and analyzed among the ALC and compared to global figures. An extensive electronic literature search to review all relevant articles and reports published from the region was conducted. The 2019 Global Health Security (GHS) index was obtained from the “GHS index” website which was made by John Hopkins University’s center for health security, the Nuclear threat Initiative (NTI) and the Economist Intelligence Unit (EIU). Government stringency index and political stability index were obtained from the University of Oxford and the website of “The Global Economy”, respectively. Other world governance indicators such as government effectiveness were obtained from the World Bank website. Results In terms of incidence of COVID-19, Iraq has the highest with 9665 per one million population, Syria the lowest at 256 per million. Deaths per million population was highest in Iraq at 237, and the lowest in Syria at 12. As for number of tests per million population, Lebanon ranked first at 136,033 with Iraq fourth at 59,795. There is no data available for the tests administered in Syria and subsequently no value for tests per million population. In terms of recoveries from COVID-19 per million population, Iraq had the highest number at 7903 per million, and Syria the lowest at 68 per million. When compared as percent recovery per million, Palestine ranked first (84%) and Syria last (27%). The government response stringency index shows that Jordan had the highest index (100) early in the pandemic among the other countries. Palestine’s index remained stable between 80 and 96. The other countries’ indices ranged from 50 to 85, with Lebanon seeing a drop to 24 in mid-August. Even with improved stringency index, Iraq reported an increased number of deaths. Conclusion In countries devastated by war and conflict, a pandemic such as COVID-19 can easily spread. The Arab Levant countries represent a breeding ground for pandemics given their unstable political and economic climate that has undoubtedly affected their healthcare systems. In the era of COVID-19, looking at healthcare systems as well as political determinants is needed to assess a country’s readiness towards the pandemic. The unrest in Lebanon, the uprising in Iraq, the restrictions placed on Syria, and the economic difficulties in Palestine are all examples of determinants affecting pandemic management. Jordan, on the contrary, is a good example of a stable state, able to implement proper measures. Political stability index should be used as a predictor for pandemic management capacity, and individual measures should be tailored towards countries depending on their index.

How do algorithms shape the imaginary and practice of security? Does their proliferation point to a shift in the political rationality of security? If so, what is the nature and extent of that shift? This article argues that efforts to strengthen global health security are major drivers in the development and proliferation of new algorithmic security technologies. In response to a seeming epidemic of potentially lethal infectious disease outbreaks – including HIV/AIDS, Severe Acute Respiratory Syndrome (SARS), pandemic flu, Middle East Respiratory Syndrome (MERS), Ebola and Zika – governments and international organizations are now using several next-generation syndromic surveillance systems to rapidly detect new outbreaks globally. This article analyses the origins, design and function of three such internet-based surveillance systems: (1) the Program for Monitoring Emerging Diseases, (2) the Global Public Health Intelligence Network and (3) HealthMap. The article shows how each newly introduced system became progressively more reliant upon algorithms to mine an ever-growing volume of indirect data sources for the earliest signs of a possible new outbreak – gradually propelling algorithms into the heart of global outbreak detection. That turn to the algorithm marks a significant shift in the underlying problem, nature and role of knowledge in contemporary security policy.

With the rapid development and broad applications of next-generation sequencing platforms and bioinformatic analytical tools, genomics has become a popular area for biosurveillance and international scientific collaboration. Governments from countries including the United States (US), Canada, Germany, and the United Kingdom have leveraged these advancements to support international cooperative programs that aim to reduce biological threats and build scientific capacity worldwide. A recent conference panel addressed the impacts of the enhancement of genomic sequencing capabilities through three major US bioengagement programs on international scientific engagement and biosecurity risk reduction. The panel contrasted the risks and benefits of supporting the enhancement of genomic sequencing capabilities through international scientific engagement to achieve biological threat reduction and global health security. The lower costs and new bioinformatic tools available have led to the greater application of sequencing to biosurveillance. Strengthening sequencing capabilities globally for the diagnosis and detection of infectious diseases through mutual collaborations has a high return on investment for increasing global health security. International collaborations based on genomics and shared sequence data can build and leverage scientific networks and improve the timeliness and accuracy of disease surveillance reporting needed to identify and mitigate infectious disease outbreaks and comply with international norms. Further efforts to promote scientific transparency within international collaboration will improve trust, reduce threats, and promote global health security.

ObjectiveThe session will discuss strategies for outbreak prevention,detection, and response for global health security and explore howthese activities inform both domestic and international initiatives.Innovations in epidemiology, laboratory, informatics, investment, andcoordination for disease surveillance will be discussed.IntroductionMultiple agencies are involved in global disease surveillance andcoordination of activities is essential to achieve broad public healthimpact. Multiple examples of effective and collaborative initiativesexist. The WHO/AFRO developed Integrated Disease Surveillanceand Response (IDSR) framework, adopted by 43 of the 46 AFROmember states and applied in other WHO regions, was the firstframework designed to strengthen national disease surveillance andresponse systems. The WHO International Health Regulations (IHR)2005 are an agreement between 196 countries to prevent, detectand respond to the international spread of disease. In 2013 CDCworked with Uganda and Vietnam to demonstrate the developmentof surveillance, laboratory, and emergency response center capacityand link data systems for six outbreak prone diseases. More recently,the Global Health Security Agenda (GHSA) was launched with thesupport of 28 countries, WHO, OIE and FAO just as Ebola wasbeginning to emerge in West Africa. This panel brings togetherCDC, local implementing partners, academic technical partners, andinternational non-government donor to discuss current and evolvingstrategies for prevention, detection, and response activities needed forglobal health security.

Abstract Background Member States lack of compliance with 2005 IHR implementation led to the launched of the Global Health Security Agenda. This research will provide an understanding of how the Global Health Security Agenda Steering Group (GHSA SG) governance interventions impact health system performance and global health security. This will enhance the understanding of a Steering Group's governance interventions in complex Global Health initiatives. Research questions: To what extent have GHSA SG governance interventions contributed towards enabling health system performance of WHO Member States? To what extent have GHSA SG governance interventions contributed towards the implementation of global health security among WHO Member States? Methods Correlational analysis using Spearman's rho examined the relationship between governance, health system performance and global health security variables at one point in time. A convenience non-probability sample consisting of eight WHO Member States was used. SPSS Statistics generated the bivariate correlation analyzes. Results Governance and health system performance analysis indicated a statistically significant strong positive effect size in 11 out of 18 and moderate positive effect size in the remaining seven out of 18 health system performance indicators. Governance and global health security analysis concluded three of the governance indicators had strong and moderate positive coefficients. Global health security variables demonstrated weak effects in the remaining three governance indicators. Conclusions This study presents a case for health systems embedding in global health security. Health system performance is only as effective at protecting populations when countries achieve core capacities of preparedness and response to global health threats. The associations provide stakeholders information about key characteristics of governance that influence health system performance and global health security implementation. Key messages This study provides an argument for the continued support of the GHSA 2024 Framework with implementation of global health security capabilities and meeting 2005 IHR requirements. The GHSA SG governance role remains profoundly important in establishing sustainable efforts internationally towards achieving the objectives of the GHSA in support of the 2005 IHR standards.
