A positive yet complicated case of gender-based violence coordination: a qualitative study of Lebanon's protracted humanitarian emergency, 2012-22.

Gender-based violence (GBV), a global health and human rights concern, often intensifies during emergencies. This paper explores the evolution of GBV coordination in Lebanon's protracted Syrian refugee crisis from 2012-22. Utilising 38 in-depth interviews and a document review, the findings were analysed using the framework for effective GBV coordination. Lebanon provides a positive yet complicated example of GBV coordination. Initially established to address the refugee crisis, it matured into a collaborative national coordination mechanism, fostering trust and advancing localisation amidst sectarian complexities. However, the volatile, restrictive policy context hindered government co-leadership and engagement with refugee-led organisations. While essential GBV response services were expanded nationwide, lack of an interagency strategy on GBV risk mitigation and prevention compromised lasting change. The paper emphasises the importance of dedicated GBV coordinators, multi-year funding, and increased attention to GBV prevention. The findings underscore the transformative potential of humanitarian responses and advocate for enhanced engagement with national stakeholders to promote sustainability in protracted crises.

Genetic and Antigenic Characterization of an Influenza A(H3N2) Outbreak in Cambodia and the Greater Mekong Subregion during the COVID-19 Pandemic, 2020.

Introduction of non-pharmaceutical interventions to control COVID-19 in early 2020 coincided with a global decrease in active influenza circulation. However, between July and November 2020, an influenza A(H3N2) epidemic occurred in Cambodia and in other neighboring countries in the Greater Mekong Subregion in Southeast Asia. We characterized the genetic and antigenic evolution of A(H3N2) in Cambodia and found that the 2020 epidemic comprised genetically and antigenically similar viruses of Clade3C2a1b/131K/94N, but they were distinct from the WHO recommended influenza A(H3N2) vaccine virus components for 2020-2021 Northern Hemisphere season. Phylogenetic analysis revealed multiple virus migration events between Cambodia and bordering countries, with Laos PDR and Vietnam also reporting similar A(H3N2) epidemics immediately following the Cambodia outbreak: however, there was limited circulation of these viruses elsewhere globally. In February 2021, a virus from the Cambodian outbreak was recommended by WHO as the prototype virus for inclusion in the 2021-2022 Northern Hemisphere influenza vaccine. IMPORTANCE The 2019 coronavirus disease (COVID-19) pandemic has significantly altered the circulation patterns of respiratory diseases worldwide and disrupted continued surveillance in many countries. Introduction of control measures in early 2020 against Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection has resulted in a remarkable reduction in the circulation of many respiratory diseases. Influenza activity has remained at historically low levels globally since March 2020, even when increased influenza testing was performed in some countries. Maintenance of the influenza surveillance system in Cambodia in 2020 allowed for the detection and response to an influenza A(H3N2) outbreak in late 2020, resulting in the inclusion of this virus in the 2021-2022 Northern Hemisphere influenza vaccine.

An innovative and integrated model for global outbreak response and research - a case study of the UK Public Health Rapid Support Team (UK-PHRST).

BACKGROUND: Despite considerable institutional experimentation at national and international levels in response to calls for global health security reform, there is little research on organisational models that address outbreak preparedness and response. Created in the aftermath of the 2013-16 West African Ebola epidemic, the United Kingdom's Public Health Rapid Support Team (UK-PHRST) was designed to address critical gaps in outbreak response illuminated during the epidemic, while leveraging existing UK institutional strengths. The partnership between the government agency, Public Health England, and an academic consortium, led by the London School of Hygiene and Tropical Medicine, seeks to integrate outbreak response, operational research and capacity building. We explored the design, establishment and early experiences of the UK-PHRST as one of the first bodies of its kind globally, paying particular attention to governance decisions which enabled them to address their complex mission. METHODS: We conducted a qualitative case study using 19 in-depth interviews with individuals knowledgeable about the team's design and implementation, review of organisational documents, and observations of meetings to analyse the UK-PHRST's creation, establishment and initial 2 years of operations. RESULTS: According to key informants, adopting a triple mandate (response, research and capacity building) established the team as novel in the global epidemic response architecture. Key governance decisions recognised as vital to the model included: structuring the team as a government-academic collaboration which leveraged long-term and complementary UK investments in public health and the higher education sector; adopting a more complex, dual reporting and funding structure to maintain an ethos of institutional balance between lead organisations; supporting a multidisciplinary team of experts to respond early in outbreaks for optimal impact; prioritising and funding epidemic research to influence response policy and practice; and ensuring the team's activities reinforced the existing global health architecture. CONCLUSION: The UK-PHRST aims to enhance global outbreak response using an innovative and integrated model that capitalises on institutional strengths of the partnership. Insights suggest that despite adding complexity, integrating operational research through the government-academic collaboration contributed significant advantages. This promising model could be adopted and adapted by countries seeking to build similar outbreak response and research capacities.

European Union training programme for tuberculosis laboratory experts: design, contribution and future direction.

BACKGROUND: Tuberculosis (TB) control programmes rely heavily on laboratories to support both clinical care and public health. Qualified personnel with adequate technical and managerial skills comprise an integral component of any quality assured laboratory. Training a new generation of TB laboratory specialists was identified as a critical priority in the European Union /European Economic Area (EU/EEA). A tailored training programme for TB reference laboratory professionals was developed and implemented within the European Reference Laboratory Network for Tuberculosis to increase the pool of technical experts available to step into leadership roles in the TB laboratory community. Three cohorts of selected laboratory specialists participated in a series of trainings from 2009 to 2016. METHODS: We conducted an evaluation of the training programme using a structured questionnaire administered via the EUSurvey website, with the aim of documenting the benefits and contribution as well as suggesting improvements and future direction of the programme. All graduated participants and all current ERLTB-Net members were invited to participate in the online survey and descriptive quantitative analysis was performed. RESULTS: The evaluation found significant benefits for both the participants and the participants' institutions, with improvements being reported in laboratory practices and management including implementation of new diagnostic techniques and career progression for participants. The training programme differed from other international and European initiatives in a number of important ways; the curriculum is unique in the scope and range of topics covered; the programme targets senior level professionals and future directors; cohorts were limited to 8-10 participants; and the programme involved a number of workshops (5-7) taking place over a two-year period. Relationships and collaborations established between individuals and institutions were valued as an important success of the initiative. Suggestions on how the impact of the programme could be enhanced included equipping participants to perform laboratory assessments in low-resource settings outside the EU, thus bolstering global TB control. CONCLUSION: Based on the findings presented the training programme has proved to be successful in developing leadership, expertise, partnerships and networks to support TB laboratories and has contributed significant benefits to strengthening European National Reference laboratories in the fight against TB.

Development, Use, and Impact of a Global Laboratory Database During the 2014 Ebola Outbreak in West Africa.

Background: The international impact, rapid widespread transmission, and reporting delays during the 2014 Ebola outbreak in West Africa highlighted the need for a global, centralized database to inform outbreak response. The World Health Organization and Emerging and Dangerous Pathogens Laboratory Network addressed this need by supporting the development of a global laboratory database. Methods: Specimens were collected in the affected countries from patients and dead bodies meeting the case definitions for Ebola virus disease. Test results were entered in nationally standardized spreadsheets and consolidated onto a central server. Results: From March 2014 through August 2016, 256343 specimens tested for Ebola virus disease were captured in the database. Thirty-one specimen types were collected, and a variety of diagnostic tests were performed. Regular analysis of data described the functionality of laboratory and response systems, positivity rates, and the geographic distribution of specimens. Conclusion: With data standardization and end user buy-in, the collection and analysis of large amounts of data with multiple stakeholders and collaborators across various user-access levels was made possible and contributed to outbreak response needs. The usefulness and value of a multifunctional global laboratory database is far reaching, with uses including virtual biobanking, disease forecasting, and adaption to other disease outbreaks.

Bolstering Community Cooperation in Ebola Resurgence Protocols: Combining Field Blood Draw and Point-of-Care Diagnosis.

Alison Galvani and colleagues describe a community-based protocol to improve cooperation with Ebola testing as well as contact tracing, quarantining, and treatment.

Genomic surveillance during the first two years of the COVID-19 pandemic - country experience and lessons learned from Türkiye.

Background: Türkiye confirmed its first case of SARS-CoV-2 on March 11, 2020, coinciding with the declaration of the global COVID-19 pandemic. Subsequently, Türkiye swiftly increased testing capacity and implemented genomic sequencing in 2020. This paper describes Türkiye's journey of establishing genomic surveillance as a middle-income country with limited prior sequencing capacity and analyses sequencing data from the first two years of the pandemic. We highlight the achievements and challenges experienced and distill globally relevant lessons. Methods: We tracked the evolution of the COVID-19 pandemic in Türkiye from December 2020 to February 2022 through a timeline and analysed epidemiological, vaccination, and testing data. To investigate the phylodynamic and phylogeographic aspects of SARS-CoV-2, we used Nextstrain to analyze 31,629 high-quality genomes sampled from seven regions nationwide. Results: Türkiye's epidemiological curve, mirroring global trends, featured four distinct waves, each coinciding with the emergence and spread of variants of concern (VOCs). Utilizing locally manufactured kits to expand testing capacity and introducing variant-specific quantitative reverse transcription polymerase chain reaction (RT-qPCR) tests developed in partnership with a private company was a strategic advantage in Türkiye, given the scarcity and fragmented global supply chain early in the pandemic. Türkiye contributed more than 86,000 genomic sequences to global databases by February 2022, ensuring that Turkish data was reflected globally. The synergy of variant-specific RT-qPCR kits and genomic sequencing enabled cost-effective monitoring of VOCs. However, data analysis was constrained by a weak sequencing sampling strategy and fragmented data management systems, limiting the application of sequencing data to guide the public health response. Phylodynamic analysis indicated that Türkiye's geographical position as an international travel hub influenced both national and global transmission of each VOC despite travel restrictions. Conclusion: This paper provides valuable insights into the testing and genomic surveillance systems adopted by Türkiye during the COVID-19 pandemic, proposing important lessons for countries developing national systems. The findings underscore the need for robust testing and sampling strategies, streamlined sample referral, and integrated data management with metadata linkage and data quality crucial for impactful epidemiological analysis. We recommend developing national genomic surveillance strategies to guide sustainable and integrated expansion of capacities built for COVID-19 and to optimize the effective utilization of sequencing data for public health action.

Gender based violence (GBV) coordination in a complex, multi-crisis context: a qualitative case study of Lebanon's compounded crises (2019-2023).

BACKGROUND: Since 2019 Lebanon has faced multiple compounded crises. Political and social instability, the COVID-19 pandemic, and the Beirut Port explosion, alongside the influx of refugees related to the ongoing Syrian conflict, have resulted in a nationwide economic emergency. In the context of the humanitarian response to the Syrian conflict, the UN and government-led gender-based violence (GBV) task force has coordinated the sub-sector since 2012. The compounded crisis, however, created new challenges for GBV coordination and service delivery, which we explore in this paper. We highlight lessons for strengthening GBV coordination in Lebanon and other complex emergencies. METHODS: We conducted 29 remote in-depth interviews, reviewed key policy documents and observed seven GBV task force meetings. We analysed and presented our findings across three key themes: context-relevant and adaptable coordination mechanisms; coordination to support GBV service delivery; and stakeholders' roles, legitimacy and power. RESULTS: Parallel response frameworks developed to address the multiple crises, created a complex humanitarian architecture within an increasingly challenging operating context, with some perceived inefficiencies. Positively, coordination was integrated under the established government-UN interagency system and the GBV task force maintained GBV sub-sector coordination. The task force was commended for effectively adapting to the evolving context, including working remotely, maintaining essential GBV services, assessing the compounded crises' impact on programming and adjusting accordingly, and harmonising guidance, tools and approaches. The importance of ensuring a government co-led response was highlighted by both UN and government informants, who pointed to examples where marginalising government leadership compromised coordination effectiveness and sustainability. The participation of local actors had become increasingly important but more difficult, with the impact of the various crises, and remote modalities, challenging service delivery and staff wellbeing. CONCLUSION: Experiences from Lebanon highlight the essential role of government leadership in coordination; the value of investing in local GBV capacity; the significance of effective national, subnational and intersectoral coordination to support service delivery and address cross-cutting GBV issues; the importance of targeted interventions to support marginalised populations; and the need to prioritize the well-being of front-line staff during crisis response. In Lebanon, and other complex crises, donors are encouraged to increase flexible, multiyear funding for GBV coordination and services, while women-led organizations should be at the forefront of recovery efforts, contributing to a more equitable society.

Genomic epidemiology of SARS-CoV-2 in Cambodia, January 2020 to February 2021.

The first case of coronavirus disease 2019 (COVID-19) in Cambodia was confirmed on 27 January 2020 in a traveller from Wuhan. Cambodia subsequently implemented strict travel restrictions, and although intermittent cases were reported during the first year of the COVID-19 pandemic, no apparent widespread community transmission was detected. Investigating the routes of severe acute respiratory coronavirus 2 (SARS-CoV-2) introduction into the country was critical for evaluating the implementation of public health interventions and assessing the effectiveness of social control measures. Genomic sequencing technologies have enabled rapid detection and monitoring of emerging variants of SARS-CoV-2. Here, we detected 478 confirmed COVID-19 cases in Cambodia between 27 January 2020 and 14 February 2021, 81.3 per cent in imported cases. Among them, fifty-four SARS-CoV-2 genomes were sequenced and analysed along with representative global lineages. Despite the low number of confirmed cases, we found a high diversity of Cambodian viruses that belonged to at least seventeen distinct PANGO lineages. Phylogenetic inference of SARS-CoV-2 revealed that the genetic diversity of Cambodian viruses resulted from multiple independent introductions from diverse regions, predominantly, Eastern Asia, Europe, and Southeast Asia. Most cases were quickly isolated, limiting community spread, although there was an A.23.1 variant cluster in Phnom Penh in November 2020 that resulted in a small-scale local transmission. The overall low incidence of COVID-19 infections suggests that Cambodia's early containment strategies, including travel restrictions, aggressive testing and strict quarantine measures, were effective in preventing large community outbreaks of COVID-19.

Strengthening pathogen genomic surveillance for health emergencies: insights from the World Health Organization's regional initiatives.

The onset of the COVID-19 pandemic triggered a rapid scale-up in the use of genomic surveillance as a pandemic preparedness and response tool. As a result, the number of countries with in-country SARS-CoV-2 genomic sequencing capability increased by 40% from February 2021 to July 2022. The Global Genomic Surveillance Strategy for Pathogens with Pandemic and Epidemic Potential 2022-2032 was launched by the World Health Organization (WHO) in March 2022 to bring greater coherence to ongoing work to strengthen genomic surveillance. This paper describes how WHO's tailored regional approaches contribute to expanding and further institutionalizing the use of genomic surveillance to guide pandemic preparedness and response measures as part of a harmonized global undertaking. Challenges to achieving this vision include difficulties obtaining sequencing equipment and supplies, shortages of skilled staff, and obstacles to maximizing the utility of genomic data to inform risk assessment and public health action. WHO is helping to overcome these challenges in collaboration with partners. Through its global headquarters, six regional offices, and 153 country offices, WHO is providing support for country-driven efforts to strengthen genomic surveillance in its 194 Member States, with activities reflecting regional specificities. WHO's regional offices serve as platforms for those countries in their respective regions to share resources and knowledge, engage stakeholders in ways that reflect national and regional priorities, and develop regionally aligned approaches to implementing and sustaining genomic surveillance within public health systems.

A conceptual framework for analysing partnership and synergy in a global health alliance: case of the UK Public Health Rapid Support Team.

Partnerships have become increasingly important in addressing complex global health challenges, a reality exemplified by the COVID-19 pandemic and previous infectious disease epidemics. Partnerships offer opportunities to create synergistic outcomes by capitalizing on complimentary skills, knowledge and resources. Despite the importance of understanding partnership functioning, research on collaboration is sparse and fragmented, with few conceptual frameworks applied to evaluate real-life partnerships in global health. In this study, we aimed to adapt and apply the Bergan Model of Collaborative Functioning (BMCF) to analyse partnership functioning in the UK Public Health Rapid Support Team (UK-PHRST), a government-academic partnership, dedicated to outbreak response and research in low- and middle-income countries. We conducted a literature review identifying important elements to adapt the framework, followed by a qualitative case study to characterize how each element, and the dynamics between them, influenced functioning in the UK-PHRST, exploring emerging themes to further refine the framework. Elements of the BMCF that our study reinforced as important included the partnership's mission, partner resources (skills, expertise and networks), leadership, the external environment, management systems and communication. Additional elements identified in the literature and critical to partnership functioning of the UK-PHRST included governance and financial structures adopted, trust and power balance, organizational culture, strategy and evaluation and knowledge management. Because of the way the UK-PHRST was structured, fostering team cohesion was an important indicator of synergy, alongside collaborative advantage. Dividing the funding and governance equally between organizations was considered crucial for maintaining institutional balance; however, diverse organizational cultures, weak communication practices and perceived power imbalances compromised team cohesion. Our analysis allowed us to make recommendations to improve partnership functioning at a critical time in the evolution of the UK-PHRST. The analysis approach and framework presented here can be used to evaluate and strengthen the management of global health partnerships to realize synergy.

Gender-based violence (GBV) coordination in humanitarian and public health emergencies: a scoping review.

BACKGROUND: Gender-based violence (GBV) is a global health, human rights, and protection issue, which can increase during emergencies. GBV coordination is an essential component of every humanitarian response, ensuring that, from the earliest phases of a crisis, accessible and safe services are available and prevention and mitigation mechanisms are implemented to reduce GBV. We sought to address the limited evidence on GBV coordination, by reviewing literature on GBV coordination in emergencies, identifying facilitators and barriers influencing effectiveness. METHODS: We conducted a scoping review on GBV coordination in emergencies from 1990 to 2020. Studies explicitly discussing GBV coordination in humanitarian, natural disaster and public health emergencies, in low or middle-income countries, were included. Using thematic analysis, we developed a six-topic framework to synthesise evidence on effective GBV coordination and present recommendations for strengthening GBV coordination in emergencies. FINDINGS: We included 28 of 964 sources identified, covering 30 different emergency settings across 22 countries. Sources spanned emergency settings, with minimal evidence in public health emergencies and none focussed solely on GBV coordination. Several sources suggested that timely establishment of GBV coordination mechanisms, led by dedicated, experienced coordinators, increased funding and strengthened service provision. GBV risk mitigation was compromised by weak commitment across sectors, poor accountability systems, and limited engagement of affected women. Inclusive GBV coordination, involving national and local actors is vital but engagement efforts have been inadequate and localisation funding targets not yet achieved. Implementation of the GBV Information Management System has reinforced coordination, funding allocation and service provision. While specialist GBV services remain insufficient, emergencies can present opportunities for expansion. Sustainability and long-term impact are compromised by over-reliance on international leadership and funding, weak commitment by governments, and limited attention to GBV prevention. CONCLUSION: Despite enhanced global commitments to addressing GBV in recent years, it remains consistently under-prioritised and under-resourced. Recommendations to strengthen GBV coordination in emergencies include: funding dedicated GBV coordination positions across all types of emergencies, building the global GBV coordination workforce, expanding inclusion of national actors and investing in GBV risk mitigation and prevention through multiyear funding. The evidence-based framework for effective GBV coordination presented here, can guide further research in diverse emergencies.

A challenging response to a Lassa fever outbreak in a non endemic area of Sierra Leone in 2019 with export of cases to The Netherlands.

INTRODUCTION: On November 20, 2019, the Sierra Leone International Health Regulations (IHR) National Focal Point was notified of an exported case of Lassa fever in The Netherlands, by a Dutch doctor who previously practiced in a rural hospital in Sierra Leone. This report describes the extent of the outbreak, possible sources of infection, and the outbreak response measures taken. METHODS: Response measures implemented to control the outbreak included coordination across multiple countries and cities, outbreak investigation, active case finding, contact tracing and monitoring, laboratory investigation, and isolation and treatment of cases. RESULTS: We report a hospital-associated outbreak that resulted in 3 confirmed cases (health workers) and 2 probable cases (patients). The case fatality rate was 60%, whereas the secondary attack rate was 14%. Two cases involved exportations to The Netherlands. Failure to detect the index case and poor adherence to infection prevention and control (IPC) protocols contributed to disease spread. Pregnancy status and nonspecific signs and symptoms of the index case contributed to failure in early case detection. CONCLUSIONS: Rapid activation of national and subnational incident management systems resulted in rapid outbreak control. We recommend regular training for clinicians on surveillance and IPC protocols and strengthening in-country Lassa virus diagnostic capacity.

Enhancing laboratory capacity during Ebola virus disease (EVD) heightened surveillance in Liberia: lessons learned and recommendations.

INTRODUCTION: Following a declaration by the World Health Organization that Liberia had successfully interrupted Ebola virus transmission on May 9th, 2015; the country entered a period of enhanced surveillance. The number of cases had significantly reduced prior to the declaration, leading to closure of eight out of eleven Ebola testing laboratories. Enhanced surveillance led to an abrupt increase in demand for laboratory services. We report interventions, achievements, lessons learned and recommendations drawn from enhancing laboratory capacity. METHODS: Using archived data, we reported before and after interventions that aimed at increasing laboratory capacity. Laboratory capacity was defined by number of laboratories with Ebola Virus Disease (EVD) testing capacity, number of competent staff, number of specimens tested, specimen backlog, daily and surge testing capacity, and turnaround time. Using Stata 14 (Stata Corporation, College Station, TX, USA), medians and trends were reported for all continuous variables. RESULTS: Between May and December 2015, interventions including recruitment and training of eight staff, establishment of one EVD laboratory facility, implementation of ten Ebola GeneXpert diagnostic platforms, and establishment of working shifts yielded an 8-fold increase in number of specimens tested, a reduction in specimens backlog to zero, and restoration of turn-around time to 24 hours. This enabled a more efficient surveillance system that facilitated timely detection and containment of two EVD clusters observed thereafter. CONCLUSION: Effective enhancement of laboratory services during high demand periods requires a combination of context-specific interventions. Building and ensuring sustainability of local capacity is an integral part of effective surveillance and disease outbreak response efforts.

Establishing Ebola Virus Disease (EVD) diagnostics using GeneXpert technology at a mobile laboratory in Liberia: Impact on outbreak response, case management and laboratory systems strengthening.

The 2014-16 Ebola Virus Disease (EVD) outbreak in West Africa highlighted the necessity for readily available, accurate and rapid diagnostics. The magnitude of the outbreak and the re-emergence of clusters of EVD cases following the declaration of interrupted transmission in Liberia, reinforced the need for sustained diagnostics to support surveillance and emergency preparedness. We describe implementation of the Xpert Ebola Assay, a rapid molecular diagnostic test run on the GeneXpert platform, at a mobile laboratory in Liberia and the subsequent impact on EVD outbreak response, case management and laboratory system strengthening. During the period of operation, site coordination, management and operational capacity was supported through a successful collaboration between Ministry of Health (MoH), World Health Organization (WHO) and international partners. A team of Liberian laboratory technicians were trained to conduct EVD diagnostics and the laboratory had capacity to test 64-100 blood specimens per day. Establishment of the laboratory significantly increased the daily testing capacity for EVD in Liberia, from 180 to 250 specimens at a time when the effectiveness of the surveillance system was threatened by insufficient diagnostic capacity. During the 18 months of operation, the laboratory tested a total of 9,063 blood specimens, including 21 EVD positives from six confirmed cases during two outbreaks. Following clearance of the significant backlog of untested EVD specimens in November 2015, a new cluster of EVD cases was detected at the laboratory. Collaboration between surveillance and laboratory coordination teams during this and a later outbreak in March 2016, facilitated timely and targeted response interventions. Specimens taken from cases during both outbreaks were analysed at the laboratory with results informing clinical management of patients and discharge decisions. The GeneXpert platform is easy to use, has relatively low running costs and can be integrated into other national diagnostic algorithms. The technology has on average a 2-hour sample-to-result time and allows for single specimen testing to overcome potential delays of batching. This model of a mobile laboratory equipped with Xpert Ebola test, staffed by local laboratory technicians, could serve to strengthen outbreak preparedness and response for future outbreaks of EVD in Liberia and the region.

Persistence of Ebola virus after the end of widespread transmission in Liberia: an outbreak report.

BACKGROUND: Outbreak response efforts for the 2014-15 Ebola virus disease epidemic in west Africa brought widespread transmission to an end. However, subsequent clusters of infection have occurred in the region. An Ebola virus disease cluster in Liberia in November, 2015, that was identified after a 15-year-old boy tested positive for Ebola virus infection in Monrovia, raised the possibility of transmission from a persistently infected individual. METHODS: Case investigations were done to ascertain previous contact with cases of Ebola virus disease or infection with Ebola virus. Molecular investigations on blood samples explored a potential linkage between Ebola virus isolated from cases in this November, 2015, cluster and epidemiologically linked cases from the 2014-15 west African outbreak, according to the national case database. FINDINGS: The cluster investigated was the family of the index case (mother, father, three siblings). Ebola virus genomes assembled from two cases in the November, 2015, cluster, and an epidemiologically linked Ebola virus disease case in July, 2014, were phylogenetically related within the LB5 sublineage that circulated in Liberia starting around August, 2014. Partial genomes from two additional individuals, one from each cluster, were also consistent with placement in the LB5 sublineage. Sequencing data indicate infection with a lineage of the virus from a former transmission chain in the country. Based on serology and epidemiological and genomic data, the most plausible scenario is that a female case in the November, 2015, cluster survived Ebola virus disease in 2014, had viral persistence or recurrent disease, and transmitted the virus to three family members a year later. INTERPRETATION: Investigation of the source of infection for the November, 2015, cluster provides evidence of Ebola virus persistence and highlights the risk for outbreaks after interruption of active transmission. These findings underscore the need for focused prevention efforts among survivors and sustained capacity to rapidly detect and respond to new Ebola virus disease cases to prevent recurrence of a widespread outbreak. FUNDING: US Centers for Disease Control and Prevention, Defense Threat Reduction Agency, and WHO.

Draft Genome Sequences of Three Mycobacterium chimaera Respiratory Isolates.

Mycobacterium chimaera is an opportunistic human pathogen implicated in both pulmonary and cardiovascular infections. Here, we report the draft genome sequences of three strains isolated from human respiratory specimens.
