Using Machine Learning Technology (Early Artificial Intelligence-Supported Response With Social Listening Platform) to Enhance Digital Social Understanding for the COVID-19 Infodemic: Development and Implementation Study.

BACKGROUND: Amid the COVID-19 pandemic, there has been a need for rapid social understanding to inform infodemic management and response. Although social media analysis platforms have traditionally been designed for commercial brands for marketing and sales purposes, they have been underused and adapted for a comprehensive understanding of social dynamics in areas such as public health. Traditional systems have challenges for public health use, and new tools and innovative methods are required. The World Health Organization Early Artificial Intelligence-Supported Response with Social Listening (EARS) platform was developed to overcome some of these challenges. OBJECTIVE: This paper describes the development of the EARS platform, including data sourcing, development, and validation of a machine learning categorization approach, as well as the results from the pilot study. METHODS: Data for EARS are collected daily from web-based conversations in publicly available sources in 9 languages. Public health and social media experts developed a taxonomy to categorize COVID-19 narratives into 5 relevant main categories and 41 subcategories. We developed a semisupervised machine learning algorithm to categorize social media posts into categories and various filters. To validate the results obtained by the machine learning-based approach, we compared it to a search-filter approach, applying Boolean queries with the same amount of information and measured the recall and precision. Hotelling T2 was used to determine the effect of the classification method on the combined variables. RESULTS: The EARS platform was developed, validated, and applied to characterize conversations regarding COVID-19 since December 2020. A total of 215,469,045 social posts were collected for processing from December 2020 to February 2022. The machine learning algorithm outperformed the Boolean search filters method for precision and recall in both English and Spanish languages (P<.001). Demographic and other filters provided useful insights on data, and the gender split of users in the platform was largely consistent with population-level data on social media use. CONCLUSIONS: The EARS platform was developed to address the changing needs of public health analysts during the COVID-19 pandemic. The application of public health taxonomy and artificial intelligence technology to a user-friendly social listening platform, accessible directly by analysts, is a significant step in better enabling understanding of global narratives. The platform was designed for scalability; iterations and new countries and languages have been added. This research has shown that a machine learning approach is more accurate than using only keywords and has the benefit of categorizing and understanding large amounts of digital social data during an infodemic. Further technical developments are needed and planned for continuous improvements, to meet the challenges in the generation of infodemic insights from social media for infodemic managers and public health professionals.

Strengthening hospital resilience in the Eastern Mediterranean Region.

"Adaptation is surviving but resilience is for thriving."In recent years, the multiple threats of COVID-19 and other disease outbreaks, intensified climate change and severe weather events, and increasing conflicts and humanitarian emergencies have highlighted the need to strengthen resilience in the different sectors, including social, economic, environment, and health. Resilience is the ability of a system, community or society exposed to hazards to resist, absorb, accommodate, adapt to, transform, and recover from the effects of a hazard in a timely and efficient manner, including through the preservation and restoration of its essential basic structures and functions through risk management.

Modelling COVID-19 vaccination status and adherence to public health and social measures, Eastern Mediterranean Region and Algeria.

Objective: To study the link between coronavirus disease 2019 (COVID-19) vaccination status and adherence to public health and social measures in Members of the Eastern Mediterranean Region and Algeria. Methods: We analysed two rounds of a large, cross-country, repeated cross-sectional mobile phone survey in June-July 2021 and October-November 2021. The rounds included 14 287 and 14 131 respondents, respectively, from 23 countries and territories. Questions covered knowledge, attitudes and practices around COVID-19, and demographic, employment, health and vaccination status. We used logit modelling to analyse the link between self-reported vaccination status and individuals' practice of mask wearing, physical distancing and handwashing. We used propensity score matching as a robustness check. Findings: Overall, vaccinated respondents (8766 respondents in round 2) were significantly more likely to adhere to preventive measures than those who were unvaccinated (5297 respondents in round 2). Odds ratios were 1.5 (95% confidence interval, CI: 1.3-1.8) for mask wearing; 1.5 (95% CI: 1.3-1.7) for physical distancing; and 1.2 (95% CI: 1.0-1.4) for handwashing. Similar results were found on analysing subsamples of low- and middle-income countries. However, in high-income countries, where vaccination coverage is high, there was no significant link between vaccination and preventive practices. The association between vaccination status and adherence to public health advice was sustained over time, even though self-reported vaccination coverage tripled over 5 months (19.4% to 62.3%; weighted percentages). Conclusion: Individuals vaccinated against COVID-19 maintained their adherence to preventive health measures. Nevertheless, reinforcement of public health messages is important for the public's continued compliance with preventive measures.

Acceptance of COVID-19 Vaccine Booster Doses Using the Health Belief Model: A Cross-Sectional Study in Low-Middle- and High-Income Countries of the East Mediterranean Region.

Coronavirus disease (COVID-19) booster doses decrease infection transmission and disease severity. This study aimed to assess the acceptance of COVID-19 vaccine booster doses in low, middle, and high-income countries of the East Mediterranean Region (EMR) and its determinants using the health belief model (HBM). In addition, we aimed to identify the causes of booster dose rejection and the main source of information about vaccination. Using the snowball and convince sampling technique, a bilingual, self-administered, anonymous questionnaire was used to collect the data from 14 EMR countries through different social media platforms. Logistic regression analysis was used to estimate the key determinants that predict vaccination acceptance among respondents. Overall, 2327 participants responded to the questionnaire. In total, 1468 received compulsory doses of vaccination. Of them, 739 (50.3%) received booster doses and 387 (26.4%) were willing to get the COVID-19 vaccine booster doses. Vaccine booster dose acceptance rates in low, middle, and high-income countries were 73.4%, 67.9%, and 83.0%, respectively (p < 0.001). Participants who reported reliance on information about the COVID-19 vaccination from the Ministry of Health websites were more willing to accept booster doses (79.3% vs. 66.6%, p < 0.001). The leading causes behind booster dose rejection were the beliefs that booster doses have no benefit (48.35%) and have severe side effects (25.6%). Determinants of booster dose acceptance were age (odds ratio (OR) = 1.02, 95% confidence interval (CI): 1.01-1.03, p = 0.002), information provided by the Ministry of Health (OR = 3.40, 95% CI: 1.79-6.49, p = 0.015), perceived susceptibility to COVID-19 infection (OR = 1.88, 95% CI: 1.21-2.93, p = 0.005), perceived severity of COVID-19 (OR = 2.08, 95% CI: 137-3.16, p = 0.001), and perceived risk of side effects (OR = 0.25, 95% CI: 0.19-0.34, p < 0.001). Booster dose acceptance in EMR is relatively high. Interventions based on HBM may provide useful directions for policymakers to enhance the population's acceptance of booster vaccination.

What is "hospital resilience"? A scoping review on conceptualization, operationalization, and evaluation.

Background: COVID-19 underscored the importance of building resilient health systems and hospitals. Nevertheless, evidence on hospital resilience is limited without consensus on the concept, its application, or measurement, with practical guidance needed for action at the facility-level. Aim: This study establishes a baseline for understanding hospital resilience, exploring its 1) conceptualization, 2) operationalization, and 3) evaluation in the empirical literature. Methods: Following Arksey and O'Malley's model, a scoping review was conducted, and a total of 38 articles were included for final extraction. Findings and discussion: In this review, hospital resilience is conceptualized by its components, capacities, and outcomes. The interdependence of six components (1) space, 2) stuff, 3) staff, 4) systems, 5) strategies, and 6) services) influences hospital resilience. Resilient hospitals must absorb, adapt, transform, and learn, utilizing all these capacities, sometimes simultaneously, through prevention, preparedness, response, and recovery, within a risk-informed and all-hazard approach. These capacities are not static but rather are dynamic and should improve continuously occur over time. Strengthening hospital resilience requires both hard and soft resilience. Hard resilience encompasses the structural (or constructive) and non-structural (infrastructural) aspects, along with agility to rearrange the space while hospital's soft resilience requires resilient staff, finance, logistics, and supply chains (stuff), strategies and systems (leadership and coordination, community engagement, along with communication, information, and learning systems). This ultimately results in hospitals maintaining their function and providing quality and continuous critical, life-saving, and essential services, amidst crises, while leaving no one behind. Strengthening hospital resilience is interlinked with improving health systems and community resilience, and ultimately contributes to advancing universal health coverage, health equity, and global health security. The nuances and divergences in conceptualization impact how hospital resilience is applied and measured. Operationalization and evaluation strategies and frameworks must factor hospitals' evolving capacities and varying risks during both routine and emergency times, especially in resource-restrained and emergency-prone settings. Conclusion: Strengthening hospital resilience requires consensus regarding its conceptualization to inform a roadmap for operationalization and evaluation and guide meaningful and effective action at facility and country level. Further qualitative and quantitative research is needed for the operationalization and evaluation of hospital resilience comprehensively and pragmatically, especially in fragile and resource-restrained contexts.

Public health emergency operation centres: status, gaps and areas for improvement in the Eastern Mediterranean Region.

The functionality of Public Health Emergency Operations Centres (PHEOCs) in countries is vital to their response capacity. The article assesses the status of National PHEOCs in the 22 countries of the Eastern Mediterranean Region. We designed and administered an online survey between May and June 2021. Meetings and Key Informant Interviews were also conducted with the emergency focal points in the WHO country offices and with other select partners. We also collected data on PHEOCs from the Joint External Evaluations conducted in the Region between 2016 and 2018 in 18 countries, and intra-action review mission reports conducted in 11 countries to review the response to COVID-19 during May 2020-June 2021 - and other relevant mission reports. Only 12 countries reported having PHEOC with varying levels of functionality and 10 of them reported using PHEOC for their response operations. This review formed the baseline of capacity requirements of National PHEOC in each country and will facilitate identifying benchmarks of areas of improvement for future national, WHO and partners support.

Operationalisation of consensual One Health roadmaps in countries for improved IHR capacities and health security.

The COVID-19 pandemic is a devastating reminder that mitigating the threat of emerging zoonotic outbreaks relies on our collective capacity to work across human health, animal health and environment sectors. Despite the critical need for shared approaches, collaborative benchmarks in the International Health Regulations (IHR) Monitoring and Evaluation Framework and more specifically the Joint External Evaluation (JEE) often reveal low levels of performance in collaborative technical areas (TAs), thus identifying a real need to work on the human-animal-environment interface to improve health security. The National Bridging Workshops (NBWs) proposed jointly by the World Organisation of Animal Health and World Health Organization (WHO) provide opportunity for national human health, animal health, environment and other relevant sectors in countries to explore the efficiency and gaps in their coordination for the management of zoonotic diseases. The results, gathered in a prioritised roadmap, support the operationalisation of the recommendations made during JEE for TAs where a multisectoral One Health approach is beneficial. For those collaborative TAs (12 out of 19 in the JEE), more than two-thirds of the recommendations can be implemented through one or multiple activities jointly agreed during NBW. Interestingly, when associated with the WHO Benchmark Tool for IHR, it appears that NBW activities are often associated with lower level of performance than anticipated during the JEE missions, revealing that countries often overestimate their capacities at the human-animal-environment interface. Deeper, more focused and more widely shared discussions between professionals highlight the need for concrete foundations of multisectoral coordination to meet goals for One Health and improved global health security through IHR.

IHR-PVS National Bridging Workshops, a tool to operationalize the collaboration between human and animal health while advancing sector-specific goals in countries.

Collaborative, One Health approaches support governments to effectively prevent, detect and respond to emerging health challenges, such as zoonotic diseases, that arise at the human-animal-environmental interfaces. To overcome these challenges, operational and outcome-oriented tools that enable animal health and human health services to work specifically on their collaboration are required. While international capacity and assessment frameworks such as the IHR-MEF (International Health Regulations-Monitoring and Evaluation Framework) and the OIE PVS (Performance of Veterinary Services) Pathway exist, a tool and process that could assess and strengthen the interactions between human and animal health sectors was needed. Through a series of six phased pilots, the IHR-PVS National Bridging Workshop (NBW) method was developed and refined. The NBW process gathers human and animal health stakeholders and follows seven sessions, scheduled across three days. The outputs from each session build towards the next one, following a structured process that goes from gap identification to joint planning of corrective measures. The NBW process allows human and animal health sector representatives to jointly identify actions that support collaboration while advancing evaluation goals identified through the IHR-MEF and the OIE PVS Pathway. By integrating sector-specific and collaborative goals, the NBWs help countries in creating a realistic, concrete and practical joint road map for enhanced compliance to international standards as well as strengthened preparedness and response for health security at the human-animal interface.

Prioritizing zoonotic diseases utilizing the One Health approach: Jordan's experience.

BACKGROUND: Zoonotic diseases constitute a threat to humans and animals. The Middle East Region is a hotspot for such a threat; given its geographic location under migratory birds' flight paths, mass gatherings, political conflicts, and refugee crises. Thus, prioritizing zoonotic diseases of national significance is critical for preventing and controlling such threats and optimizing limited resources. Using a multi-sectoral One Health (OH) approach, this study aimed at prioritizing zoonotic diseases of national significance to Jordan and identifying future recommendations and action plans. METHODS: Zoonotic diseases of national significance to Jordan were initially identified (n = 27 diseases). In December 2019, national staff from governmental and non-state sectors were invited to develop ranking criteria, including questions and answers choices, and to weigh each criterion. Then, the national staff were asked to assess zoonotic diseases' priority using the developed criteria and provide recommendations and action plans to strengthen multi-sectoral collaboration. RESULTS: Seven zoonotic diseases were identified as being of great significance. Rabies was ranked as the number one priority disease, followed by middle east respiratory syndrome, avian influenza, brucellosis, leishmaniasis, rickettsiosis, and salmonellosis. The highest weighted criteria used to rank diseases were disease severity, outbreaks profile, and potential human-to-human transmission. Establishing a one-health platform, surveillance, laboratory, preparedness planning, outbreak response, and workforce were suggested as recommendations for approaching the priority diseases. Respondents identified data sharing, coordination, event-based surveillance, and effective communication channels as vital areas to enhance prevention and control strategies, conduct joint outbreak investigations, and improve multi-sectoral collaboration. CONCLUSIONS: This study represents the first attempt to prioritize zoonotic diseases of national significance in Jordan using the OH approach and a semi-qualitative, transparent, and comparative method. Study results can be used as a decision-making guide for policymakers and stakeholders and a cornerstone for combating zoonotic disease threats.

Leveraging the COVID-19 response to improve emergency care systems in the Eastern Mediterranean Region.

The COVID-19 pandemic began as a cluster of reported cases of acute respiratory illness in China on 31 December 2019 and went on to spread with exponential growth across the globe. By the time it was characterized as a global pandemic on 11 March 2020, 17 of 22 countries in the Eastern Mediterranean Region (EMR) had reports of infected persons. EMR countries are particularly susceptible to such outbreaks due to the presence of globally interconnected markets; complex emergencies in more than half of the countries; religious mass gatherings that draw tens of millions of pilgrims annually; and variation in emergency care systems capacity and health systems performance within and between countries.

One Health operational framework for action for the Eastern Mediterranean Region, focusing on zoonotic diseases.

Human health is intrinsically linked to the health of animals and to the environment, and efforts by just one sector alone cannot prevent or adequately address the complex problems at the human-animal-environment interface. Countries of the World Health Organization Eastern Mediterranean Region, as any other region, face the threat of emerging and remerging zoonoses. However, the challenges in this Region are high given the lack of resources, poor health systems, and political factors. Hence, adopting the One Health approach becomes urgent to assist those countries. Subsequently, based on analysis of One Health capacities in the Region and in close consultation with representatives and subject matter experts from countries in the Region, a framework for action towards effectively implementing the One Health approach was developed. The framework capitalizes on current opportunities in the region and provide countries with a list of practical key activities towards optimal use of their resources and strengthening their capabilities to tackle concurrent and future health challenges at the interface. Strong governance structures and building on existing mechanisms are crucial for achieving effective disease surveillance and response. Additionally, using intersectoral approaches for risk assessment and risk mitigation for health issues at the human-animal-environment interface can improve efficiency and result in more successful outcomes.

Coronavirus Disease 2019 outbreak: preparedness and readiness of countries in the Eastern Mediterranean Region.

On 31 December 2019, a cluster of acute respiratory illness was reported from China and later confirmed as novel coronavirus on 7 January 2020. This virus is the same member of the coronavirus family that caused the severe acute respiratory syndrome (SARS-CoV) reported in China 2003, and Middle East respiratory syndrome (MERS-CoV) reported in Saudi Arabia in 2012. The initial cases have been linked to a live seafood market in Wuhan, China, and the specific animal source is yet to be determined. The detection of this new virus in humans without knowing the source of the infection has raised greatly heightened concerns not only in China, but also internationally. To date, the outbreak has spread to most provinces in China and 25 other countries within a relatively short period. Consequent to its spread, Dr Tedros Ghebreyesus, Director General of the World Health Organization (WHO), declared the outbreak a Public Health Emergency of International Concern (PHEIC) on 30 January 2020.

Development of a Costed National Action Plan for Health Security in Pakistan: Lessons Learned.

In order to assess progress toward achieving compliance with the International Health Regulations (2005), member states may voluntarily request a Joint External Evaluation (JEE). Pakistan was the first country in the WHO Eastern Mediterranean Region to volunteer for and complete a JEE to establish the baseline of the country's public health capacity across multiple sectors covering 19 technical areas. It subsequently developed a post-JEE costed National Action Plan for Health Security (NAPHS). The process for developing the costed NAPHS was based on objectives and activities related to the 3 to 5 priority actions for each of the 19 JEE technical areas. Four key lessons were learned during the process of developing the NAPHS. First, multisectoral coordination at both federal and provincial levels is important in a devolved health system, where provinces are autonomous from a public health sector standpoint. Second, the development of a costed NAPHS requires engagement and investment of the country's own resources for sustainability as well as donor coordination among national and international donors and partners. Engagement from the ministries of Finance, Planning and Development, and Foreign Affairs and from WHO was also important. Third, development of predefined goals, targets, and indicators aligned with the JEE as part of the NAPHS process proved to be critical, as they can be used to monitor progress toward implementation of the NAPHS and provide data for repeat JEEs. Lastly, several challenges were identified related to the NAPHS process and costing tool, which need to be addressed by WHO and partners to help countries develop their plans.
