Rapid response teams in the Eastern Mediterranean Region: Results from the baseline survey of country-level capacities, operations and outbreak response capabilities.

The aim of this study is to assess WHO/Eastern Mediterranean region (WHO/EMR) countries capacities, operations and outbreak response capabilities. Cross-sectional study was conducted targeting 22 WHO/EMR countries from May to June 2021. The survey covers 8 domains related to 15 milstones and key performance indicators (KPIs) for RRT. Responses were received from 14 countries. RRTs are adequately organised in 9 countries (64.3%). The mean retention rate of RRT members was 85.5% ± 22.6. Eight countries (57.1%) reported having standard operating procedures, but only three countries (21.4%) reported an established mechanism of operational fund allocation. In the last 6 months, 10,462 (81.9%) alerts were verified during the first 24 h. Outbreak response was completed by the submission of final RRT response reports in 75% of analysed outbreaks. Risk Communication and Community Engagement (RCCE) activities were part of the interventional response in 59.5% of recent outbreaks. Four countries (28.6%) reported an adequate system to assess RRTs operations. The baseline data highlights four areas to focus on: developing and maintaining the multidisciplinary nature of RRTs through training, adequate financing and timely release of funds, capacity and system building for implementing interventions, for instance, RCCE, and establishing national monitoring and evaluation systems for outbreak response.

A phased strengthening of laboratory capacity in the Eastern Mediterranean Region during the COVID-19 pandemic.

The Eastern Mediterranean Region (EMR) faces ongoing challenges in its public health system due to limited resources, logistical issues, and political disruptions. The COVID-19 pandemic accelerated the need for stronger laboratory capacities to handle the increased demand for testing. In a phased response, EMR countries utilized the National Influenza Centers to rapidly establish and scale molecular testing for SARS-CoV-2, the causative agent of COVID-19. The expansion of capacity included strong collaborations between public health bodies and private and academic sectors to decentralize and expand testing to the subnational level. To ensure that the quality of testing was not impacted by rapid expansion, national and subnational laboratories were enrolled in external quality assurance programs for the duration of the response. Implementation of genomic surveillance was prioritized for variant tracking, leading to the establishment of regional sequencing reference laboratories and the distribution of MinION sequencing platforms to complex emergency countries who previously had limited experience with pathogen sequencing. Challenges included a lack of technical expertise, including in implementing novel diagnostic assays and sequencing, a lack of bioinformatics expertise in the region, and significant logistical and procurement challenges. The collaborative approach, coordinated through the WHO Eastern Mediterranean Regional Office, enabled all 22 countries to achieve SARS-CoV-2 diagnostic capabilities, highlighting the pivotal role of laboratories in global health security.

Learning From COVID-19: What Would It Take to Be Better Prepared in the Eastern Mediterranean Region?

The COVID-19 transmission in the Eastern Mediterranean Region (EMR) was influenced by various factors such as conflict, demographics, travel and social restrictions, migrant workers, weak health systems, and mass gatherings. The countries that responded well to COVID-19 had high-level political commitment, multisectoral coordination, and existing infrastructures that could quickly mobilize. However, some EMR countries faced challenges due to political instability and fragile health systems, which hindered their response strategies. The pandemic highlighted the region's weak health systems and preparedness, fragmented surveillance systems, and lack of trust in information sharing. COVID-19 exposed the disruption of access and delivery of essential health services as a major health system fragility. In 2020, the World Health Organization (WHO) conducted a global pulse survey, which demonstrated that the EMR experienced the highest disruption in health services compared to other WHO regions. However, thanks to prioritization by the WHO and its member states, significant improvement was observed in 2021 during the second round of the WHO's National Pulse Survey. The pandemic underscored the importance of political leadership, community engagement, and trust and emphasized that investing in health security benefits everyone. Increasing vaccine coverage, building regional capacities, strengthening health systems, and working toward universal health coverage and health security are all priorities in the EMR. Emergency public health plays a key role in preparing for and responding to pandemics and biological threats. Integrating public health into primary care and investing in public health workforce capacity building is essential to reshaping public health and health emergency preparedness.

Achieving integrated disease surveillance in the Eastern Mediterranean Region.

Access to reliable and timely information is key for healthcare decision-making at the regional, national and sub-national levels. However, lack of access to such information hampers to progress towards achievement of the Sustainable Development Goals (SDGs) in the Eastern Mediterranean Region (EMR), as indicated in the Regional Progress Report on Health-Related Sustainable Development Goals.

Role of research Laboratories in pandemic and epidemic response in the Eastern Mediterranean Region: Experiences from COVID-19, avian influenza, and MERS-CoV.

We share the experience of research laboratories in the Eastern Mediterranean Region (EMR) that contributed to preparedness and response to highly pathogenic avian influenza (HPAI), Middle-East respiratory syndrome coronavirus (MERS-CoV), and coronavirus disease (COVID-19). Research groups in the region were pivotal in identifying, characterizing the pathogens and describing their evolution, distribution, transmission routes, and the immunological profile of exposed populations. They demonstrated the capacity to develop and test antivirals and potential vaccines. The EMR experience is a model of how national systems can work with researchers to improve regional preparedness and response to future epidemics and pandemics.

Progress Toward Measles Elimination - World Health Organization Eastern Mediterranean Region, 2019-2022.

In 2015, all 22 World Health Organization Eastern Mediterranean Region (EMR) countries and areas (countries) pledged to achieve measles elimination by 2020. Despite success in several countries, most countries in the region still have not eliminated measles. This report updates a previous report and describes progress toward measles elimination in EMR during 2019-2022. During that period, estimated regional coverage with the first and second doses of a measles-containing vaccine (MCV) was 82%-83% and 76%-78%, respectively. During 2019-2022, approximately 160 million children were vaccinated during national or subnational supplementary immunization activities. Reported confirmed regional measles incidence decreased from 29.8 cases per 1 million population in 2019 to 7.4 in 2020, but then increased 68%, to 50.0 in 2022 because of challenges providing immunization services and conducting surveillance during the COVID-19 pandemic. Surveillance indicators deteriorated in 11 (50%) of the 22 EMR countries. During 2019-2022, four countries in the region were verified as having achieved measles elimination, but other countries reported immunity gaps and increased measles incidence in 2022. To achieve measles elimination in EMR, national immunization programs, especially in those countries with high measles incidence, will need to continue to recover from the COVID-19 pandemic, increase overall vaccination coverage to close immunity gaps, and maintain high-quality disease surveillance.

Geographical distribution of Bartonella spp in the countries of the WHO Eastern Mediterranean Region (WHO-EMRO).

Bartonellosis is a vector-borne and zoonotic diseases in humans, especially in immunocompromised individuals. However, there is no complete data about the geographical distribution of different species of Bartonella, as well as the status of its reservoirs, vectors, and human cases in most parts of the world. In this study, published reports related to Bartonella species from WHO-EMRO region countries were searched in different databases until October 2023. The eighteens different species of Bartonella were reported in WHO-EMRO countries including Bartonella henselae, Bartonella quintana, Bartonella elizabethae, Bartonella bovis, Bartonella clarridgeiae, Bartonella vinsonii, Bartonella doshiae, Bartonella taylorii, Bartonella rochalimae, Bartonella tribocorum, Bartonella rattimassiliensis, candidatus Bartonella merieuxii, candidatus Bartonella dromedarii, Bartonella acomydis, Bartonella jaculi, Bartonella coopersplainsensis and Bartonella koehlerae. Also, only human cases of B. henselae and B. quintana infections were reported from WHO-EMRO countries. The infections of Bartonella are important in the WHO-EMRO region, but they have been neglected by clinicians and healthcare systems.

Insights from a modelling analysis of COVID-19 vaccination in the Eastern Mediterranean Region.

Background: Understanding the main determinants of COVID-19 vaccine uptake is critical to increasing vaccine coverage. This is particularly important for COVID-19 vaccine uptake, which has been affected by both demand and supply issues. Aim: To understand the links between vaccine uptake and demand and supply issues in the WHO Eastern Mediterranean and UNICEF Middle East and North Africa regions. Methods: We collected data through 2 rounds of a repeated cross-sectional phone survey from 11 000 individuals across 16 low- and middle-income countries. We used logit modelling to distil the main characteristics of the 4 vaccination categories (vaccinated, unvaccinated but willing, unvaccinated and undecided, and unvaccinated and unwilling) while also considering vaccine availability. We conducted sub-regional analysis to account for differences in level of development between the low- and middle-income countries. Results: Despite the increase in vaccination coverage from 60.9% at the end of 2021 to 78.3% by August 2022, about 9% were not willing and were not vaccinated during the two rounds of interviews. Our modelling analysis revealed that positive beliefs about safety, effectiveness and side effects of the COVID-19 vaccines were associated with increased odds of being vaccinated or willingness to be vaccinated. Those who did not believe in the safety of the vaccines were less likely to be vaccinated than those who believed in the safety of the vaccines (OR: 0.56; 95% CI: 0.46-0.67). By contrast, negative beliefs about the COVID-19 vaccines increased the probability of being unwilling to be vaccinated. Conclusion: The results from this research offer useful insights into tackling the supply and demand related barriers to COVID-19 vaccination uptake and provides lessons for future health threats.

Effect of climate change on nature and human health with a special focus on infectious diseases in the Mediterranean region.

INTRODUCTION: In this short review, the effect of climate change on nature and human health with a special focus on infectious diseases in the Mediterranean region is discussed. This research is a part of the Mediterranean Convention of Human Rights project, which is an organizational work on human rights issues that was established in cooperation with civil society and the national authorities of the Mediterranean Region. METHODOLOGY: Previously published data were collected by retrieving published literature from PubMed, Google Scholar, and Web of Science using "climate change", "the Mediterranean region", "infections in Mediterranean Region", "infectious diseases", "biodiversity", and "the Mediterranean Sea" as keywords. The collected data were then evaluated and reviewed. The recommendations and guidelines were analysed by the preferred reporting items for systematic reviews and meta-analyses (PRISMA). CONCLUSIONS: The Mediterranean region presents a typical example witnessing a dramatic change in climate events and their adverse impact on biodiversity, ecosystems and public health are multiple. This negative impact is in part due to the geographical particularities, and sociocultural and geopolitical conflicts that are progressively worsening the burden of climate change. While most of these changes cannot be totally avoided, many of the health risks related to climate change could be monitored. This can be done by establishing health systems with policies to reduce and prevent the risks of infectious diseases and to recover and support the affected areas, which may identify priority and management of high-risk events.

Strengthening influenza surveillance capacity in the Eastern Mediterranean Region: Nearly two decades of direct support from the United States Centers for Disease Control and Prevention.

Since 2004, the US Centers for Disease Control and Prevention (CDC) Influenza Division (ID) has supported seven countries in the Eastern Mediterranean region and the World Health Organization Regional Office for the Eastern Mediterranean to establish and strengthen influenza surveillance. The substantial growth of influenza surveillance capacities in the region demonstrates a commitment by governments to strengthen national programs and contribute to global surveillance. The full value of surveillance data is in its use to guide local public health decisions. CDC ID remains committed to supporting the region and supporting partners to translate surveillance data into policies and programs effectively.

Monitoring the quality of SARS-CoV-2 virus detection in molecular diagnostic laboratories in the Eastern Mediterranean Region during the COVID-19 pandemic.

INTRODUCTION: The COVID-19 pandemic placed unprecedented stress on laboratories in the Eastern Mediterranean Region. Building on existing capacity for influenza diagnostics, countries introduced COVID-19 diagnostic support to ~100% regional coverage. A key challenge during the expansion was maintaining quality testing in laboratories, ensuring that correct results were shared with medical facilities. METHODS: WHO organized two rounds of independently monitored severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) external quality assurance programs (EQAP). The Public Health Laboratory (PHL) division of WHO supplied external quality assurance (EQA) panels, from the Royal College of Pathologists of Australasia Quality Assurance Programme (RCPAQAP) Australia to laboratories not enrolled in recurring Global Influenza Surveillance and Response System (GISRS) quality assurance programs, in which national influenza centers routinely participate. RESULTS: Fifteen and 14 countries participated in PHL/EQAP for SARS-CoV-2 between 2020 and 2022. Concordance was consistent between rounds, reaching 96.4% and 89.9%. A separate assessment of GISRS/EQAP to national-level laboratories identified high levels of response and concordance for SARS-CoV-2 (100% response, 93% concordance), which was reduced for influenza (50% response rate, 80% concordance), reflecting the challenge of prioritizing pathogens during outbreaks. CONCLUSION: The proliferation of laboratories in response to COVID-19 was a success story from the pandemic. However, monitoring the quality of laboratories was challenging via existing EQAP. The addition of PHL/EQAP provided a mechanism to monitor performance of laboratories that were not designated as national influenza centers. While a high proportion of laboratories attained good results, continual emphasis on quality and enrollment in EQAP is key to ensuring sustainability of laboratory testing in future.

Key aspects defining the development and implementation of a regional genomic surveillance strategy for the Eastern Mediterranean Region.

The COVID-19 pandemic highlighted the critical role of pathogen sequencing in making informed public health decisions. Initially, the Eastern Mediterranean Region faced limitations in sequencing capacity. However, with robust WHO and stakeholder support, the situation significantly improved. By 2022, COVID-19 sequencing was underway in 22 out of 23 regional countries, with varying throughput and capacity. Notably, three genomic hubs were established in Oman, UAE, and Morocco, playing a key role in providing expanded genomics training and support across the region. While primarily for COVID-19 surveillance, this sequencing capacity offers an opportunity to integrate genomic surveillance into existing networks. This integration can enable early detection and response to high-threat pathogens with pandemic potential. To advance this, WHO/EMRO collaborated with stakeholders to formulate the Eastern Mediterranean Regional Genomic Surveillance Strategy for Emerging Pathogens of Pandemic Concern. Consultative meetings with regional and international genomic surveillance experts identified strategy focal points, key partners, priority pathogens, and implementation steps. As the strategy awaits member states' ratification in Q4 2023, this manuscript outlines pivotal facets defined by member states and the strategic document's key deliverables and opportunities. These efforts aim to yield a substantial positive impact within the region.

Enhancing the quality and accuracy of national cancer registries in the Eastern Mediterranean Region.

We cannot prevent cancer, detect it early, diagnose, treat, and palliate it without reliable data. Continuous, systematic collection, analysis, and interpretation of cancer-related data are essential to effectively plan, implement and evaluate cancer control activities and policies. Enhancing routine health information systems to ensure that cancer-related data are well captured is essential, just as fostering functioning cancer surveillance systems, particularly population-based cancer registries (1,2). Population-based cancer registries play a critical role in the planning of national cancer control and prevention strategies, monitoring and evaluation of cancer care services, as well as cancer epidemiological and clinical research (1).

Immunization in the Eastern Mediterranean Region: some signs of post-COVID-19 recovery, but more work ahead.

Every year, WHO and UNICEF estimate the immunization coverage for 195 Member States, based on reported data and independent coverage surveys (1,2). These estimates indicate progress in reaching children with life-saving vaccines while identifying coverage gaps (3). The 2022 estimates were much awaited, given that the COVID-19 pandemic caused a setback in coverage (1). Overall, there are encouraging signs of recovery in the WHO Eastern Mediterranean Region (EMR). For example, coverage of the third dose diphtheria-pertussis-tetanus containing vaccine (DTPcv3) and the second dose measles containing vaccine (MCV2), both almost restored or exceeded their 85% and 76% pre-pandemic 2019 levels, respectively (1). However, there are disparities across countries. Low-income countries with fragile, weak health systems and those in conflict situation are lagging. The number of children who missed their routine first dose of measles immunization increased from 3 million in 2019 to 3.16 million in 2022 (1). This underperformance, along with the accumulated immunity gap in 2020-2021, exposes us to the risk of preventable deadly outbreaks.

Capacity-building for conducting COVID-19 vaccine effectiveness studies to enhance evidence-informed vaccination policymaking in the Eastern Mediterranean Region.

Background: Vaccine effectiveness studies provide evidence on the effects of vaccines for preventing disease and the adverse outcomes following a vaccination rollout programme in a country or a specific population. Aims: To document the technical and capacity-building support provided by WHO to countries in the Eastern Mediterranean Region to conduct COVID-19 vaccine effectiveness studies. Methods: WHO implemented interventions to enhance the capacity of EMR countries to conduct COVID-19 vaccine effectiveness and similar epidemiological studies. The intervention consisted of several components, including methodological and technical support as well as data and project management at national and regional levels. Two WHO generic protocols were adopted: cohort study among healthcare workers and test-negative design in severe acute respiratory infections surveillance sites. Results: Egypt, Islamic Republic of Iran, Jordan, and Pakistan participated in the programme. The research protocols were adjusted to country context and settings. WHO provided technical, financial and infrastructure support, including the establishment of quality assessment approaches, study conduct, data management, report development, statistical data analysis, and experience-sharing between the countries. Technical capacity-building was also offered to other countries not involved in the vaccine effectiveness studies. Conclusion: COVID-19 pandemic provided an opportunity to enhance the research capacities of EMR countries for the conduct of vaccine effectiveness studies. The WHO consolidated efforts and its collaboration with countries resulted in enhancement of capacity and research infrastructure, especially in the 4 countries that were supported by this programme. The capacities acquired through the programme would be very useful for other vaccine-preventable communicable diseases, thus better informing national immunization programmes and policies in EMR countries.

Systematic review and meta-analysis of childhood visual impairment in the Eastern Mediterranean Region.

Background: Childhood visual impairment has a significant effect on social life, educational performance, and professional choices, and can lead to poverty. Aims: To review the prevalence and causes of visual impairment among children aged 5-17 years in the Eastern Mediterranean Region (EMR). Methods: This study was conducted in 2021 using the Preferred Reporting Items for Systematic reviews and Meta- Analyses (PRISMA) method. We searched Google Scholar, PubMed, Web of Science, Scopus, Index Medicus for the Eastern Mediterranean Region, and Medline for studies published between January 2000 and April 2020. The articles included were epidemiological studies of prevalence and causes of childhood visual impairment published in peer-reviewed journals. Results: Of the 12 705 articles screened, 23 from 9 countries met the inclusion criteria. The pooled prevalence of uncorrected, presenting, and best-corrected childhood visual impairment was 11.57%, 8.34% and 1.21%, respectively. The most common causes of childhood visual impairment were refractive error (51.89%), amblyopia (11.15%), retinal disorders (3.90%), corneal opacity (3.0%), and cataract (1.88%). There was a highly significant heterogeneity between the studies (P < 0.0001). Conclusion: The prevalence of visual impairment among children in the EMR was high, and the leading causes were uncorrected refractive error and amblyopia, which were avoidable. Access to eyecare services may help improve early diagnosis and treatment of preventable causes of childhood visual impairment.

Prevalence of injecting drug use and HIV, hepatitis B, and hepatitis C in people who inject drugs in the Eastern Mediterranean region: a systematic review and meta-analysis.

BACKGROUND: Considerable disease burden is attributed to injecting drug use (IDU). This regional systematic review and meta-analysis aimed to assess the prevalence of IDU and the characteristics of people who inject drugs in the 22 countries of the WHO Eastern Mediterranean region. METHODS: We conducted a systematic review and meta-analysis on the prevalence of IDU, estimation of the population size of people who inject drugs, the characteristics of people who inject drugs, commonly injected drugs, the prevalence of HIV, hepatitis C virus, and hepatitis B virus in people who inject drugs, and opioid agonist treatment and needle and syringe programme services. We searched PubMed, Web of Science, Scopus, Embase, and the Index Medicus for the Eastern Mediterranean Region for documents published between Jan 1, 2010, and April 17, 2022, with no language restrictions. We also searched government reports, civil society information, and UN websites and databases for grey literature published between Jan 1, 2010, and April 17, 2022. Documents were eligible if they reported or estimated an indicator of interest, or reported enough data to permit calculation of the indicator. We extracted data from the eligible documents and calculated national and regional estimates. FINDINGS: We identified 38 283 documents and included 201 documents in the systematic review. A total of 115 documents were included for the four outcomes for which meta-analyses were performed. The number of people who inject drugs was estimated as 864 597 (95% CI 641 909-1 205 255), amounting to a prevalence of 20·0 per 10 000 adults (95% CI 14·9-27·9) in the region. Among people who inject drugs, the prevalence of HIV was estimated as 19·22% (95% CI 12·86-26·36), hepatitis C virus as 44·82% (29·32-61·16), and hepatitis B virus as 2·66% (0·84-7·26). Countries varied greatly regarding the variables of interest and the availability of relevant data. Nine countries provided needle and syringe programme services and seven countries provided opioid agonist treatment services, mostly with very low, low, or unclear coverage. INTERPRETATION: The prevalence of IDU in the Eastern Mediterranean region is lower than the global mean, particularly among women. The HIV infection rate is higher than the global mean, and the hepatitis C virus infection rate is lower than the global mean. Harm-reduction services are underdeveloped. Data collection on IDU and provision of services need improvement in the region. FUNDING: World Health Organization.

Enhancing the use of geographic information systems for public health planning and decision-making in the WHO Eastern Mediterranean Region.

From distributing healthcare resources equitably to identifying disease outbreaks, most of the information needs of local health system decision-makers have a geographic component (1). Recognizing the value of geographic information systems for public health planning and decision-making, a 2007 resolution by the Regional Committee of the World Health Organization (WHO) Eastern Mediterranean Region (EMR) called upon Member States to develop institutional frameworks, policies, processes, and to provide the infrastructure and resources needed to support health mapping activities in EMR (2).

The insidious return of cholera in the Eastern Mediterranean Region, Lebanon and Syria: a worrying signal! Past, present, and future forthcoming.

Introduction: War, hunger, and disease continue to decimate the populations of many countries in the world. Owing to conflicts, environmental instability and natural disasters, many people, especially the poorest, fall victim to epidemic diseases. One such disease, cholera, began to spread again in 2022, striking Lebanon and Syria, countries that have experienced serious social troubles for years. The return of cholera immediately alarmed the scientific community, which is now making every effort, most notably by implementing a major vaccination campaign, to prevent this disease from becoming endemic in these two countries, thus making them a reservoir for its potential spread in the Eastern Mediterranean Region. Discussion: Cholera is a disease that draws its strength from poor hygiene, primitive sanitation and the consumption of contaminated water and food. From the 19th Century onwards, its spread was facilitated by overcrowded housing and lack of hygiene, which became commonplace features of urban life. Method: In outlining the spread of cholera in Lebanon and Syria, the authors raise the question of the possible resurgence of epidemic cholera, especially in the light of the consequences of the devastating earthquake that hit the border area between Turkey and Syria last February. Conclusion: These events have had a devastating effect on the population, destroying, among other things, the few existing health facilities and aggravating the already difficult living conditions of millions of people who, owing to the ongoing war, have been living for years in makeshift settlements, bereft of water, sanitation and any form of health care.
