Leveraging science to advance health equity: Preliminary considerations for implementing health equity science at state and local health departments
Ottewell A , Ruebush E , Hayes L , Harper-Hardy P , Lewis M , Lane JT , Bunnell R . J Public Health Manag Pract 2024 CONTEXT: In 2021, the Centers for Disease Control and Prevention (CDC) launched CORE, an agency-wide strategy to embed health equity as a foundational component across all areas of the agency's work. The CDC established a definition of health equity science (HES) and principles to guide the development, implementation, dissemination, and use of the HES framework to move beyond documenting inequities to investigating root causes and promoting actionable approaches to eliminate health inequities. The HES framework may be used by state and local health departments to advance health equity efforts in their jurisdictions. OBJECTIVE: Identify implementation considerations and opportunities for providing technical assistance and support to state and local public health departments in advancing HES. DESIGN: A series of implementation consultations and multi-jurisdictional facilitated discussions were held with state and local health departments and community partners in 5 states to gather feedback on the current efforts, opportunities, and support needs to advance HES at the state and local levels. The information shared during these activities was analyzed using inductive and deductive methods, validated with partners, and summarized into themes and HES implementation considerations. RESULTS: Five themes emerged regarding current efforts, opportunities, and support needed to implement HES at state and local health departments. These themes included the following criteria: (1) enhancing the existing health equity evidence base; (2) addressing interdisciplinary public health practice and data needs; (3) recognizing the value of qualitative data; (4) evaluating health equity programs and policies; and (5) including impacted communities in the full life cycle of health equity efforts. Within these themes, we identified HES implementation considerations, which may be leveraged to inform future efforts to advance HES at the state and local levels. CONCLUSION: Health equity efforts at state and local health departments may be strengthened by leveraging the HES framework and implementation considerations. |
Neuroinvasive bacillus cereus infection in immunocompromised hosts: Epidemiologic investigation of 5 patients with acute myeloid leukemia

Open Forum Infect Dis 2024 11 (3) ofae048 BACKGROUND: Bacillus cereus is a ubiquitous gram-positive rod-shaped bacterium that can cause sepsis and neuroinvasive disease in patients with acute leukemia or neutropenia. METHODS: A single-center retrospective review was conducted to evaluate patients with acute leukemia, positive blood or cerebrospinal fluid test results for B cereus, and abnormal neuroradiographic findings between January 2018 and October 2022. Infection control practices were observed, environmental samples obtained, a dietary case-control study completed, and whole genome sequencing performed on environmental and clinical Bacillus isolates. RESULTS: Five patients with B cereus neuroinvasive disease were identified. All patients had acute myeloid leukemia (AML), were receiving induction chemotherapy, and were neutropenic. Neurologic involvement included subarachnoid or intraparenchymal hemorrhage or brain abscess. All patients were treated with ciprofloxacin and survived with limited or no neurologic sequelae. B cereus was identified in 7 of 61 environmental samples and 1 of 19 dietary protein samples-these were unrelated to clinical isolates via sequencing. No point source was identified. Ciprofloxacin was added to the empiric antimicrobial regimen for patients with AML and prolonged or recurrent neutropenic fevers; no new cases were identified in the ensuing year. CONCLUSIONS: B cereus is ubiquitous in the hospital environment, at times leading to clusters with unrelated isolates. Fastidious infection control practices addressing a range of possible exposures are warranted, but their efficacy is unknown and they may not be sufficient to prevent all infections. Thus, including B cereus coverage in empiric regimens for patients with AML and persistent neutropenic fever may limit the morbidity of this pathogen. |
Principles of health equity science for public health action
Burton DC , Kelly A , Cardo D , Daskalakis D , Huang DT , Penman-Aguilar A , Raghunathan PL , Zhu BP , Bunnell R . Public Health Rep 2023 333549231213162 Health equity is the state in which everyone has a fair and just opportunity to attain their highest level of health, and no one is disadvantaged from achieving this potential because of social position or other socially determined circumstances.1 Science is a cornerstone of public health and central to efforts to achieve health equity. Science designed to generate knowledge to advance equity can improve population health and promote health for all members of society.2 In contrast, science and interventions not designed and implemented with equity in mind may inadvertently perpetuate or widen disparities, even while fostering overall improvements in population health.3 | Health equity science provides a conceptual framework for scientific endeavors that are designed and conducted to advance health equity.4 Health equity science investigates patterns and underlying contributors to health inequities and builds an evidence base that can guide action across the domains of the public health program, surveillance, policy, communication, and scientific inquiry to move toward eliminating, rather than simply documenting, inequities. | Building on extensive work in developing the importance and application of equity concepts in public health practice,5-7 we describe an equity-focused scientific framework and set of principles to guide public health efforts to fulfill the health equity mission of the Centers for Disease Control and Prevention (CDC).8 |
Commentary: Modernizing guidelines development to speed the transfer of science to patient care
Bunnell R . Am J Med Qual 2023 38 S1-s2 On behalf of the Centers for Disease Control and Prevention (CDC), I would like to commend the many people who contributed to the work reflected in this special supplement, which is an important step toward modernizing guideline development and implementation for public health action. | | Science must be translated into clinical and public health practice more rapidly. Clinicians need the latest guidelines quickly at hand to achieve the best health outcomes. While the evidence-to-practice time gap has somewhat improved in the past 20 years,1 computable clinical practice guidelines (CPGs) can accelerate this trend by increasing adoption of guidelines by health care providers.2 This supplement presents new processes and standards to rapidly develop actionable CPGs that are effective at improving practice, based on insights gained through CDC’s Adapting Clinical Guidelines for the Digital Age (ACG) initiative and lessons learned during the COVID-19 pandemic. ACG brought together public and private sector experts from multiple disciplines and contexts to streamline the development of computable guidelines and related products for implementation in patient care workflows and health information systems. |
A technology-enabled multi-disciplinary team-based care model for the management of Long COVID and other fatiguing illnesses within a federally qualified health center: protocol for a two-arm, single-blind, pragmatic, quality improvement professional cluster randomized controlled trial
Godino JG , Samaniego JC , Sharp SP , Taren D , Zuber A , Armistad AJ , Dezan AM , Leyba AJ , Friedly JL , Bunnell AE , Matthews E , Miller MJ , Unger ER , Bertolli J , Hinckley A , Lin JS , Scott JD , Struminger BB , Ramers C . Trials 2023 24 (1) 524 BACKGROUND: The clinical burden of Long COVID, myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), and other post-infectious fatiguing illnesses (PIFI) is increasing. There is a critical need to advance understanding of the effectiveness and sustainability of innovative approaches to clinical care of patients having these conditions. METHODS: We aim to assess the effectiveness of a Long COVID and Fatiguing Illness Recovery Program (LC&FIRP) in a two-arm, single-blind, pragmatic, quality improvement, professional cluster, randomized controlled trial in which 20 consenting clinicians across primary care clinics in a Federally Qualified Health Center system in San Diego, CA, will be randomized at a ratio of 1:1 to either participate in (1) weekly multi-disciplinary team-based case consultation and peer-to-peer sharing of emerging best practices (i.e., teleECHO (Extension for Community Healthcare Outcomes)) with monthly interactive webinars and quarterly short courses or (2) monthly interactive webinars and quarterly short courses alone (a control group); 856 patients will be assigned to participating clinicians (42 patients per clinician). Patient outcomes will be evaluated according to the study arm of their respective clinicians. Quantitative and qualitative outcomes will be measured at 3- and 6-months post-baseline for clinicians and every 3-months post assignment to a participating clinician for patients. The primary patient outcome is change in physical function measured using the Patient-Reported Outcomes Measurement Information System (PROMIS)-29. Analyses of differences in outcomes at both the patient and clinician levels will include a linear mixed model to compare change in outcomes from baseline to each post-baseline assessment between the randomized study arms. A concurrent prospective cohort study will compare the LC&FIRP patient population to the population enrolled in a university health system. Longitudinal data analysis approaches will allow us to examine differences in outcomes between cohorts. DISCUSSION: We hypothesize that weekly teleECHO sessions with monthly interactive webinars and quarterly short courses will significantly improve clinician- and patient-level outcomes compared to the control group. This study will provide much needed evidence on the effectiveness of a technology-enabled multi-disciplinary team-based care model for the management of Long COVID, ME/CFS, and other PIFI within a federally qualified health center.

Health equity in the implementation of genomics and precision medicine: A public health imperative.
Khoury MJ , Bowen S , Dotson WD , Drzymalla E , Green RF , Goldstein R , Kolor K , Liburd LC , Sperling LS , Bunnell R . Genet Med 2022 24 (8) 1630-1639 Recent reviews have emphasized the need for a health equity agenda in genomics research. To ensure that genomic discoveries can lead to improved health outcomes for all segments of the population, a health equity agenda needs to go beyond research studies. Advances in genomics and precision medicine have led to an increasing number of evidence-based applications that can reduce morbidity and mortality for millions of people (tier 1). Studies have shown lower implementation rates for selected diseases with tier 1 applications (familial hypercholesterolemia, Lynch syndrome, hereditary breast and ovarian cancer) among racial and ethnic minority groups, rural communities, uninsured or underinsured people, and those with lower education and income. We make the case that a public health agenda is needed to address disparities in implementation of genomics and precision medicine. Public health actions can be centered on population-specific needs and outcomes assessment, policy and evidence development, and assurance of delivery of effective and ethical interventions. Crucial public health activities also include engaging communities, building coalitions, improving genetic health literacy, and building a diverse workforce. Without concerted public health action, further advances in genomics with potentially broad applications could lead to further widening of health disparities in the next decade. |
Toward a New Strategic Public Health Science for Policy, Practice, Impact, and Health Equity.
Bunnell R , Ryan J , Kent C . Am J Public Health 2021 111 (8) e1-e8 The COVID-19 pandemic and its social and health impact have underscored the need for a new strategic science agenda for public health. To optimize public health impact, high-quality strategic science addresses scientific gaps that inform policy and guide practice. At least 6 scientific gaps emerge fromthe US experience with COVID-19: health equity science, data science and modernization, communication science, policy analysis and translation, scientific collaboration, and climate science. Addressing these areas within a strategic public health science agenda will accelerate achievement of public health goals. Public health leadership and scientists have an unprecedented opportunity to use strategic science to guide a new era of improved and equitable public health. (Am J Public Health.

Barriers and facilitators to reporting deaths following Ebola surveillance in Sierra Leone: implications for sustainable mortality surveillance based on an exploratory qualitative assessment
Jalloh MF , Kinsman J , Conteh J , Kaiser R , Jambai A , Ekström AM , Bunnell RE , Nordenstedt H . BMJ Open 2021 11 (5) e042976 OBJECTIVES: To understand the barriers contributing to the more than threefold decline in the number of deaths (of all causes) reported to a national toll free telephone line (1-1-7) after the 2014-2016 Ebola outbreak ended in Sierra Leone and explore opportunities for improving routine death reporting as part of a nationwide mortality surveillance system. DESIGN: An exploratory qualitative assessment comprising 32 in-depth interviews (16 in Kenema district and 16 in Western Area). All interviews were audio-recorded, transcribed and analysed using qualitative content analysis to identify themes. SETTING: Participants were selected from urban and rural communities in two districts that experienced varying levels of Ebola cases during the outbreak. All interviews were conducted in August 2017 in the post-Ebola-outbreak context in Sierra Leone when the Sierra Leone Ministry of Health and Sanitation was continuing to mandate reporting of all deaths. PARTICIPANTS: Family members of deceased persons whose deaths were not reported to the 1-1-7 system. RESULTS: Death reporting barriers were driven by the lack of awareness to report all deaths, lack of services linked to reporting, negative experiences from the Ebola outbreak including prohibition of traditional burial rituals, perception that inevitable deaths do not need to be reported and situations where prompt burials may be needed. Facilitators of future willingness to report deaths were largely influenced by the perceived communicability and severity of the disease, unexplained circumstances of the death that need investigation and the potential to leverage existing death notification practices through local leaders. CONCLUSIONS: Social mobilisation and risk communication efforts are needed to help the public understand the importance and benefits of sustained and ongoing death reporting after an Ebola outbreak. Localised practices for informal death notification through community leaders could be integrated into the formal reporting system to capture community-based deaths that may otherwise be missed. |
Impact of Kenya's Frontline Epidemiology Training Program on Outbreak Detection and Surveillance Reporting: A Geographical Assessment, 2014-2017
Macharia D , Jinnai Y , Hirai M , Galgalo T , Lowther SA , Ekechi CO , Widdowson MA , Turcios-Ruiz R , Williams SG , Baggett HKC , Bunnell RE , Oyugi E , Langat D , Makayotto L , Gura Z , Cassell CH . Health Secur 2021 19 (3) 243-253 Rapid detection and response to infectious disease outbreaks requires a robust surveillance system with a sufficient number of trained public health workforce personnel. The Frontline Field Epidemiology Training Program (Frontline) is a focused 3-month program targeting local ministries of health to strengthen local disease surveillance and reporting capacities. Limited literature exists on the impact of Frontline graduates on disease surveillance completeness and timeliness reporting. Using routinely collected Ministry of Health data, we mapped the distribution of graduates between 2014 and 2017 across 47 Kenyan counties. Completeness was defined as the proportion of complete reports received from health facilities in a county compared with the total number of health facilities in that county. Timeliness was defined as the proportion of health facilities submitting surveillance reports on time to the county. Using a panel analysis and controlling for county-fixed effects, we evaluated the relationship between the number of Frontline graduates and priority disease reporting of measles. We found that Frontline training was correlated with improved completeness and timeliness of weekly reporting for priority diseases. The number of Frontline graduates increased by 700%, from 57 graduates in 2014 to 456 graduates in 2017. The annual average rates of reporting completeness increased from 0.8% in 2014 to 55.1% in 2017. The annual average timeliness reporting rates increased from 0.1% in 2014 to 40.5% in 2017. These findings demonstrate how global health security implementation progress in workforce development may influence surveillance and disease reporting. |

National reporting of deaths after enhanced Ebola surveillance in Sierra Leone
Jalloh MF , Kaiser R , Diop M , Jambai A , Redd JT , Bunnell RE , Castle E , Alpren C , Hersey S , Ekstrom AM , Nordenstedt H . PLoS Negl Trop Dis 2020 14 (8) e0008624 BACKGROUND: Sierra Leone experienced the largest documented epidemic of Ebola Virus Disease in 2014-2015. The government implemented a national tollfree telephone line (1-1-7) for public reporting of illness and deaths to improve the detection of Ebola cases. Reporting of deaths declined substantially after the epidemic ended. To inform routine mortality surveillance, we aimed to describe the trends in deaths reported to the 1-1-7 system and to quantify people's motivations to continue reporting deaths after the epidemic. METHODS: First, we described the monthly trends in the number of deaths reported to the 1-1-7 system between September 2014 and September 2019. Second, we conducted a telephone survey in April 2017 with a national sample of individuals who reported a death to the 1-1-7 system between December 2016 and April 2017. We described the reported deaths and used ordered logistic regression modeling to examine the potential drivers of reporting motivations. FINDINGS: Analysis of the number of deaths reported to the 1-1-7 system showed that 12% of the expected deaths were captured in 2017 compared to approximately 34% in 2016 and over 100% in 2015. We interviewed 1,291 death reporters in the survey. Family members reported 56% of the deaths. Nearly every respondent (94%) expressed that they wanted the 1-1-7 system to continue. The most common motivation to report was to obey the government's mandate (82%). Respondents felt more motivated to report if the decedent exhibited Ebola-like symptoms (adjusted odds ratio 2.3; 95% confidence interval 1.8-2.9). CONCLUSIONS: Motivation to report deaths that resembled Ebola in the post-outbreak setting may have been influenced by knowledge and experiences from the prolonged epidemic. Transitioning the system to a routine mortality surveillance tool may require a robust social mobilization component to match the high reporting levels during the epidemic, which exceeded more than 100% of expected deaths in 2015. |

Jalloh MF , Sengeh P , Bunnell RE , Jalloh MB , Monasch R , Li W , Mermin J , Deluca N , Brown V , Nur SA , August EM , Ransom RL , Namageyo-Funa A , Clements SA , Dyson M , Hageman K , Pratt SA , Nuriddin A , Carroll DD , Hawk N , Manning C , Hersey S , Marston BJ , Kilmarx PH , Conteh L , Ekström AM , Zeebari Z , Redd JT , Nordenstedt H , Morgan O . Bull World Health Organ 2020 98 (5) 330-340B Objective To evaluate changes in Ebola-related knowledge, attitudes and prevention practices during the Sierra Leone outbreak between 2014 and 2015. Methods Four cluster surveys were conducted: two before the outbreak peak (3499 participants) and two after (7104 participants). We assessed the effect of temporal and geographical factors on 16 knowledge, attitude and practice outcomes. Findings Fourteen of 16 knowledge, attitude and prevention practice outcomes improved across all regions from before to after the outbreak peak. The proportion of respondents willing to: (i) welcome Ebola survivors back into the community increased from 60.0% to 89.4% (adjusted odds ratio, aOR: 6.0; 95% confidence interval, CI: 3.9–9.1); and (ii) wait for a burial team following a relative’s death increased from 86.0% to 95.9% (aOR: 4.4; 95% CI: 3.2–6.0). The proportion avoiding unsafe traditional burials increased from 27.3% to 48.2% (aOR: 3.1; 95% CI: 2.4–4.2) and the proportion believing spiritual healers can treat Ebola decreased from 15.9% to 5.0% (aOR: 0.2; 95% CI: 0.1–0.3). The likelihood respondents would wait for burial teams increased more in high-transmission (aOR: 6.2; 95% CI: 4.2–9.1) than low-transmission (aOR: 2.3; 95% CI: 1.4–3.8) regions. Self-reported avoidance of physical contact with corpses increased in high but not low-transmission regions, aOR: 1.9 (95% CI: 1.4–2.5) and aOR: 0.8 (95% CI: 0.6–1.2), respectively. Conclusion Ebola knowledge, attitudes and prevention practices improved during the Sierra Leone outbreak, especially in high-transmission regions. Behaviourally-targeted community engagement should be prioritized early during outbreaks. |
Ebola vaccine Family first! Evidence from using a brief measure on Ebola vaccine demand in a national household survey during the outbreak in Sierra Leone
Jalloh MF , Wallace AS , Bunnell RE , Carter RJ , Redd JT , Nur SA , Zeebari Z , Ekstrom AM , Nordenstedt H . Vaccine 2020 38 (22) 3854-3861 BACKGROUND: Vaccination against Ebolavirus is an emerging public health tool during Ebola Virus Disease outbreaks. We examined demand issues related to deployment of Ebolavirus vaccine during the 2014-2015 outbreak in Sierra Leone. METHODS: A cluster survey was administered to a population-based sample in December 2014 (N = 3540), before any Ebola vaccine was available to the general public in Sierra Leone. Ebola vaccine demand was captured in this survey by three Likert-scale items that were used to develop a composite score and dichotomized into a binary outcome to define high demand. A multilevel logistic regression model was fitted to assess the associations between perceptions of who should be first to receive an Ebola vaccine and the expression of high demand for an Ebola vaccine. RESULTS: The largest proportion of respondents reported that health workers (35.1%) or their own families (29.5%) should receive the vaccine first if it became available, rather than politicians (13.8%), vaccination teams (9.8%), or people in high risk areas (8.2%). High demand for an Ebola vaccine was expressed by 74.2% of respondents nationally. The odds of expressing high demand were 13 times greater among those who said they or their families should be the first to take the vaccine compared to those who said politicians should be the first recipients (adjusted odds ratio [aOR] 13.0 [95% confidence interval [CI] 7.8-21.6]). The ultra-brief measure of the Ebola vaccine demand demonstrated acceptable scale reliability (Cronbach's alpha = 0.79) and construct validity (single-factor loadings > 0.50). CONCLUSION: Perceptions of who should be the first to get the vaccine was associated with high demand for Ebola vaccine around the peak of the outbreak in Sierra Leone. Using an ultra-brief measure of Ebola vaccine demand is a feasible solution in outbreak settings and can help inform development of future rapid assessment tools. |
Long-distance effects of epidemics: Assessing the link between the 2014 West Africa Ebola outbreak and U.S. exports and employment
Kostova D , Cassell CH , Redd JT , Williams DE , Singh T , Martel LD , Bunnell RE . Health Econ 2019 28 (11) 1248-1261 Although the economic consequences of epidemic outbreaks to affected areas are often well documented, little is known about how these might carry over into the economies of unaffected regions. In the absence of direct pathogen transmission, global trade is one mechanism through which geographically distant epidemics could reverberate to unaffected countries. This study explores the link between global public health events and U.S. economic outcomes by evaluating the role of the 2014 West Africa Ebola outbreak in U.S. exports and exports-supported U.S. jobs, 2005-2016. Estimates were obtained using difference-in-differences models where sub-Saharan Africa countries were assigned to treatment and comparison groups based on their Ebola transmission status, with controls for observed and unobserved time-variant factors that may independently influence trends in trade. Multiple model specification checks were performed to ensure analytic robustness. The year of peak transmission, 2014, was estimated to result in $1.08 billion relative reduction in U.S. merchandise exports to Ebola-affected countries, whereas estimated losses in exports-supported U.S. jobs exceeded 1,200 in 2014 and 11,000 in 2015. These findings suggest that remote disruptions in health security might play a role in U.S. economic indicators, demonstrating the interconnectedness between global health and aspects of the global economy and informing the relevance of health security efforts. |
Global health security: Protecting the United States in an interconnected world
Bunnell RE , Ahmed Z , Ramsden M , Rapposelli K , Walter-Garcia M , Sharmin E , Knight N . Public Health Rep 2019 134 (1) 3-10 On September 30, 2014, the Centers for Disease Control and Prevention (CDC) received a report of a laboratory-confirmed case of Ebola virus disease (Ebola) in a man who had traveled from Liberia to Dallas, Texas. Two nurses who cared for him were eventually confirmed as having Ebola. Three weeks later, a physician who had recently returned from West Africa to New York City developed symptoms and had laboratory confirmation of Ebola infection. These 4 cases placed an astounding burden of work on the state and local health departments involved and required the efforts of hundreds of health care workers.1–3 The economic impact was steep; Congress allocated more than $570 million to CDC for the US domestic Ebola response as part of a larger $5.4 billion appropriation for Ebola and health security.4 The 4 cases of Ebola illustrate how the interconnectedness of today’s world brings an increased risk for disease acquisition, both in the United States and abroad. |
Perceptions and acceptability of an experimental Ebola vaccine among health care workers, frontline staff, and the general public during the 2014-2015 Ebola outbreak in Sierra Leone
Jalloh MF , Jalloh MB , Albert A , Wolff B , Callis A , Ramakrishnan A , Cramer E , Sengeh P , Pratt SA , Conteh L , Hajjeh R , Bunnell R , Redd JT , Ekstrom AM , Nordenstedt H . Vaccine 2019 37 (11) 1495-1502 INTRODUCTION: Experimental Ebola vaccines were introduced during the 2014-2015 Ebola outbreak in West Africa. Planning for the Sierra Leone Trial to Introduce a Vaccine against Ebola (STRIVE) was underway in late 2014. We examined hypothetical acceptability and perceptions of experimental Ebola vaccines among health care workers (HCWs), frontline workers, and the general public to guide ethical communication of risks and benefits of any experimental Ebola vaccine. METHODS: Between December 2014 and January 2015, we conducted in-depth interviews with public health leaders (N=31), focus groups with HCWs and frontline workers (N=20), and focus groups with members of the general public (N=15) in Western Area Urban, Western Area Rural, Port Loko, Bombali, and Tonkolili districts. Themes were identified using qualitative content analysis. RESULTS: Across all participant groups, not knowing the immediate and long-term effects of an experimental Ebola vaccine was the most serious concern. Some respondents feared that experimental vaccines may cause Ebola, lead to death, or result in other adverse events. Among HCWs, not knowing the level of protection provided by experimental Ebola vaccines was another concern. HCWs and frontline workers were motivated to help find a vaccine for Ebola to help end the outbreak. General public participants cited positive experiences with routine childhood immunization in Sierra Leone. DISCUSSION: Our formative assessment prior to STRIVE's implementation in Sierra Leone helped identify concerns, motivations, and information gaps among potential participants of an experimental Ebola vaccine trial, at the time when an unprecedented outbreak was occurring in the country. The findings from this assessment were incorporated early in the process to guide ethical communication of risks and benefits when discussing informed consent for possible participation in the vaccine trial that was launched later in 2015. |
Building global health security capacity: The role for implementation science
Morgan J , Kennedy ED , Pesik N , Angulo FJ , Craig AS , Knight NW , Bunnell RE . Health Secur 2018 16 S5-s7 Since the launch of the Global Health Security Agenda (GHSA) in 2014,1-3 many countries around the world have accelerated efforts to achieve compliance with the World Health Organization's (WHO) International Health Regulations (IHR 2005) to build their capacities to detect, assess, and report public health events.4 WHO approved a standardized Joint External Evaluation (JEE) tool in February 2016 that provides a framework for assessing a country's gaps and progress toward IHR 2005 implementation.5,6 By October 2018, more than 86 countries in 6 regions had completed a JEE.7 Based on JEE scores and recommended priority actions for improvement, multiple countries, in collaboration with technical partners such as the US Centers for Disease Control and Prevention (CDC), are actively working to build their capacities and strengthen core systems to prevent, detect, and respond to public health threats. |
Systemic absorption of nicotine following acute secondhand exposure to electronic cigarette aerosol in a realistic social setting
Melstrom P , Sosnoff C , Koszowski B , King BA , Bunnell R , Le G , Wang L , Thanner MH , Kenemer B , Cox S , DeCastro BR , McAfee T . Int J Hyg Environ Health 2018 221 (5) 816-822 Evidence suggests exposure of nicotine-containing e-cigarette aerosol to nonusers leads to systemic absorption of nicotine. However, no studies have examined acute secondhand exposures that occur in public settings. Here, we measured the serum, saliva and urine of nonusers pre- and post-exposure to nicotine via e-cigarette aerosol. Secondarily, we recorded factors affecting the exposure. Six nonusers of nicotine-containing products were exposed to secondhand aerosol from ad libitum e-cigarette use by three e-cigarette users for 2h during two separate sessions (disposables, tank-style). Pre-exposure (baseline) and post-exposure peak levels (Cmax) of cotinine were measured in nonusers' serum, saliva, and urine over a 6-hour follow-up, plus a saliva sample the following morning. We also measured solution consumption, nicotine concentration, and pH, along with use behavior. Baseline cotinine levels were higher than typical for the US population (median serum session one=0.089ng/ml; session two=0.052ng/ml). Systemic absorption of nicotine occurred in nonusers with baselines indicative of no/low tobacco exposure, but not in nonusers with elevated baselines. Median changes in cotinine for disposable exposure were 0.007ng/ml serum, 0.033ng/ml saliva, and 0.316ng/mg creatinine in urine. For tank-style exposure they were 0.041ng/ml serum, 0.060ng/ml saliva, and 0.948ng/mg creatinine in urine. Finally, we measured substantial differences in solution nicotine concentrations, pH, use behavior and consumption. Our data show that although exposures may vary considerably, nonusers can systemically absorb nicotine following acute exposure to secondhand e-cigarette aerosol. This can particularly affect sensitive subpopulations, such as children and women of reproductive age. |
Trust, fear, stigma and disruptions: community perceptions and experiences during periods of low but ongoing transmission of Ebola virus disease in Sierra Leone, 2015
Nuriddin A , Jalloh MF , Meyer E , Bunnell R , Bio FA , Jalloh MB , Sengeh P , Hageman KM , Carroll DD , Conteh L , Morgan O . BMJ Glob Health 2018 3 (2) e000410 Social mobilisation and risk communication were essential to the 2014-2015 West African Ebola response. By March 2015, >8500 Ebola cases and 3370 Ebola deaths were confirmed in Sierra Leone. Response efforts were focused on 'getting to zero and staying at zero'. A critical component of this plan was to deepen and sustain community engagement. Several national quantitative studies conducted during this time revealed Ebola knowledge, personal prevention practices and traditional burial procedures improved as the outbreak waned, but healthcare system challenges were also noted. Few qualitative studies have examined these combined factors, along with survivor stigma during periods of ongoing transmission. To obtain an in-depth understanding of people's perceptions, attitudes and behaviours associated with Ebola transmission risks, 27 focus groups were conducted between April and May 2015 with adult Sierra Leonean community members on: trust in the healthcare system, interactions with Ebola survivors, impact of Ebola on lives and livelihood, and barriers and facilitators to ending the outbreak. Participants perceived that as healthcare practices and facilities improved, so did community trust. Resource management remained a noted concern. Perceptions of survivors ranged from sympathy and empathy to fear and stigmatisation. Barriers included persistent denial of ongoing Ebola transmission, secret burials and movement across porous borders. Facilitators included personal protective actions, consistent messaging and the inclusion of women and survivors in the response. Understanding community experiences during the devastating Ebola epidemic provides practical lessons for engaging similar communities in risk communication and social mobilisation during future outbreaks and public health emergencies. |

BMJ Glob Health 2018 3 (2) e000471 Background: The mental health impact of the 2014-2016 Ebola epidemic has been described among survivors, family members and healthcare workers, but little is known about its impact on the general population of affected countries. We assessed symptoms of anxiety, depression and post-traumatic stress disorder (PTSD) in the general population in Sierra Leone after over a year of outbreak response. Methods: We administered a cross-sectional survey in July 2015 to a national sample of 3564 consenting participants selected through multistaged cluster sampling. Symptoms of anxiety and depression were measured by Patient Health Questionnaire-4. PTSD symptoms were measured by six items from the Impact of Events Scale-revised. Relationships among Ebola experience, perceived Ebola threat and mental health symptoms were examined through binary logistic regression. Results: Prevalence of any anxiety-depression symptom was 48% (95% CI 46.8% to 50.0%), and of any PTSD symptom 76% (95% CI 75.0% to 77.8%). In addition, 6% (95% CI 5.4% to 7.0%) met the clinical cut-off for anxiety-depression, 27% (95% CI 25.8% to 28.8%) met levels of clinical concern for PTSD and 16% (95% CI 14.7% to 17.1%) met levels of probable PTSD diagnosis. Factors associated with higher reporting of any symptoms in bivariate analysis included region of residence, experiences with Ebola and perceived Ebola threat. Knowing someone quarantined for Ebola was independently associated with anxiety-depression (adjusted OR (AOR) 2.3, 95% CI 1.7 to 2.9) and PTSD (AOR 2.095% CI 1.5 to 2.8) symptoms. Perceiving Ebola as a threat was independently associated with anxiety-depression (AOR 1.69 95% CI 1.44 to 1.98) and PTSD (AOR 1.86 95% CI 1.56 to 2.21) symptoms. Conclusion: Symptoms of PTSD and anxiety-depression were common after one year of Ebola response; psychosocial support may be needed for people with Ebola-related experiences. Preventing, detecting, and responding to mental health conditions should be an important component of global health security efforts. |
Contributions of the US Centers for Disease Control and Prevention in implementing the global health security agenda in 17 partner countries
Fitzmaurice AG , Mahar M , Moriarty LF , Bartee M , Hirai M , Li W , Gerber AR , Tappero JW , Bunnell R . Emerg Infect Dis 2017 23 (13) S15-24 The Global Health Security Agenda (GHSA), a partnership of nations, international organizations, and civil society, was launched in 2014 with a mission to build countries' capacities to respond to infectious disease threats and to foster global compliance with the International Health Regulations (IHR 2005). The US Centers for Disease Control and Prevention (CDC) assists partner nations to improve IHR 2005 capacities and achieve GHSA targets. To assess progress through these CDC-supported efforts, we analyzed country activity reports dating from April 2015 through March 2017. Our analysis shows that CDC helped 17 Phase I countries achieve 675 major GHSA accomplishments, particularly in the cross-cutting areas of public health surveillance, laboratory systems, workforce development, and emergency response management. CDC's engagement has been critical to these accomplishments, but sustained support is needed until countries attain IHR 2005 capacities, thereby fostering national and regional health protection and ensuring a world safer and more secure from global health threats. |
Progress and opportunities for strengthening global health security
Angulo FJ , Cassell CH , Tappero JW , Bunnell RE . Emerg Infect Dis 2017 23 (13) S1-S4 In today’s interconnected world, an infectious disease outbreak that is not rapidly detected and controlled at its source can become a costly global health threat, both in lives lost and economic turmoil (1,2). Every year, thousands of outbreaks occur worldwide, many of which involve pathogens with pandemic potential. Since 2009, the World Health Organization (WHO) has declared public health emergencies of international concern for outbreaks of influenza A(H1N1) in 2009, Ebola in West Africa in 2014, and Zika in the Americas in 2015 (2). In 2007, the International Health Regulations 2005 (IHR 2005) entered into force, and all 196 state parties were legally bound to implement the core capacity required under the regulations. However, in 2014, almost two thirds of member states reported not being in compliance (3). To accelerate progress toward IHR 2005 compliance, the Global Health Security Agenda (GHSA) was launched by 29 countries, WHO, the Food and Agriculture Organization of the United Nations, and the World Organisation for Animal Health in 2014 and now includes >60 nations (4). |
Risk communication and Ebola-specific knowledge and behavior during 2014-2015 outbreak, Sierra Leone
Winters M , Jalloh MF , Sengeh P , Jalloh MB , Conteh L , Bunnell R , Li W , Zeebari Z , Nordenstedt H . Emerg Infect Dis 2018 24 (2) 336-344 We assessed the effect of information sources on Ebola-specific knowledge and behavior during the 2014-2015 Ebola virus disease outbreak in Sierra Leone. We pooled data from 4 population-based knowledge, attitude, and practice surveys (August, October, and December 2014 and July 2015), with a total of 10,604 respondents. We created composite variables for exposures (information sources: electronic, print, new media, government, community) and outcomes (knowledge and misconceptions, protective and risk behavior) and tested associations by using logistic regression within multilevel modeling. Exposure to information sources was associated with higher knowledge and protective behaviors. However, apart from print media, exposure to information sources was also linked to misconceptions and risk behavior, but with weaker associations observed. Knowledge and protective behavior were associated with the outbreak level, most strongly after the peak, whereas risk behavior was seen at all levels of the outbreak. In future outbreaks, close attention should be paid to dissemination of information. |
US Centers for Disease Control and Prevention and its partners' contributions to global health security
Tappero JW , Cassell CH , Bunnell RE , Angulo FJ , Craig A , Pesik N , Dahl BA , Ijaz K , Jafari H , Martin R . Emerg Infect Dis 2017 23 (13) S5-S14 To achieve compliance with the revised World Health Organization International Health Regulations (IHR 2005), countries must be able to rapidly prevent, detect, and respond to public health threats. Most nations, however, remain unprepared to manage and control complex health emergencies, whether due to natural disasters, emerging infectious disease outbreaks, or the inadvertent or intentional release of highly pathogenic organisms. The US Centers for Disease Control and Prevention (CDC) works with countries and partners to build and strengthen global health security preparedness so they can quickly respond to public health crises. This report highlights selected CDC global health protection platform accomplishments that help mitigate global health threats and build core, cross-cutting capacity to identify and contain disease outbreaks at their source. CDC contributions support country efforts to achieve IHR 2005 compliance, contribute to the international framework for countering infectious disease crises, and enhance health security for Americans and populations around the world. |
Relevance of global health security to the US export economy
Cassell CH , Bambery Z , Roy K , Meltzer MI , Ahmed Z , Payne RL , Bunnell RE . Health Secur 2017 15 (6) 563-568 To reduce the health security risk and impact of outbreaks around the world, the US Centers for Disease Control and Prevention and its partners are building capabilities to prevent, detect, and contain outbreaks in 49 global health security priority countries. We examine the extent of economic vulnerability to the US export economy posed by trade disruptions in these 49 countries. Using 2015 US Department of Commerce data, we assessed the value of US exports and the number of US jobs supported by those exports. US exports to the 49 countries exceeded $308 billion and supported more than 1.6 million jobs across all US states in agriculture, manufacturing, mining, oil and gas, services, and other sectors. These exports represented 13.7% of all US export revenue worldwide and 14.3% of all US jobs supported by all US exports. The economic linkages between the United States and these global health security priority countries illustrate the importance of ensuring that countries have the public health capacities needed to control outbreaks at their source before they become pandemics. |
National survey of Ebola-related knowledge, attitudes and practices before the outbreak peak in Sierra Leone: August 2014
Jalloh MF , Sengeh P , Monasch R , Jalloh MB , DeLuca N , Dyson M , Golfa S , Sakurai Y , Conteh L , Sesay S , Brown V , Li W , Mermin J , Bunnell R . BMJ Glob Health 2017 2 (4) e000285 Background: The 2014-2015 Ebola epidemic in West Africa was the largest ever to occur. In the early phases, little was known about public knowledge, attitudes and practices (KAP) relating to Ebola virus disease (Ebola). Data were needed to develop evidence-driven strategies to address gaps in knowledge and practice. Methods: In August 2014, we conducted interviews with 1413 randomly selected respondents from 9 out of 14 districts in Sierra Leone using multistage cluster sampling. Where suitable, Ebola-related KAP questions were adapted from other internationally validated questionnaires related to infectious diseases. Results: All respondents were aware of Ebola. When asked unprompted, 60% of respondents could correctly cite fever, diarrhoea and vomiting as signs/symptoms of Ebola. A majority of respondents knew that avoiding infected blood and bodily fluids (87%) and contact with an infected corpse (85%) could prevent Ebola. However, there were also widespread misconceptions such as the belief that Ebola can be prevented by washing with salt and hot water (41%). Almost everyone interviewed (95%) expressed at least one discriminatory attitude towards Ebola survivors. Unprompted, self-reported actions taken to avoid Ebola infection included handwashing with soap (66%) and avoiding physical contact with patients with suspected Ebola (40%). Conclusion: Three months into the 2014 Ebola outbreak in Sierra Leone, our findings suggest there was high awareness of the disease but misconceptions and discriminatory attitudes toward survivors remained common. These findings directly informed the development of a national social mobilisation strategy and demonstrated the importance of KAP assessment early in an epidemic. |
Knowledge, attitudes, and practices related to Ebola virus disease at the end of a national epidemic - Guinea, August 2015
Jalloh MF , Robinson SJ , Corker J , Li W , Irwin K , Barry AM , Ntuba PN , Diallo AA , Jalloh MB , Nyuma J , Sellu M , VanSteelandt A , Ramsden M , Tracy L , Raghunathan PL , Redd JT , Martel L , Marston B , Bunnell R . MMWR Morb Mortal Wkly Rep 2017 66 (41) 1109-1115 Health communication and social mobilization efforts to improve the public's knowledge, attitudes, and practices (KAP) regarding Ebola virus disease (Ebola) were important in controlling the 2014-2016 Ebola epidemic in Guinea (1), which resulted in 3,814 reported Ebola cases and 2,544 deaths.* Most Ebola cases in Guinea resulted from the washing and touching of persons and corpses infected with Ebola without adequate infection control precautions at home, at funerals, and in health facilities (2,3). As the 18-month epidemic waned in August 2015, Ebola KAP were assessed in a survey among residents of Guinea recruited through multistage cluster sampling procedures in the nation's eight administrative regions (Boke, Conakry, Faranah, Kankan, Kindia, Labe, Mamou, and Nzerekore). Nearly all participants (92%) were aware of Ebola prevention measures, but 27% believed that Ebola could be transmitted by ambient air, and 49% believed they could protect themselves from Ebola by avoiding mosquito bites. Of the participants, 95% reported taking actions to avoid getting Ebola, especially more frequent handwashing (93%). Nearly all participants (91%) indicated they would send relatives with suspected Ebola to Ebola treatment centers, and 89% said they would engage special Ebola burial teams to remove corpses with suspected Ebola from homes. Of the participants, 66% said they would prefer to observe an Ebola-affected corpse from a safe distance at burials rather than practice traditional funeral rites involving corpse contact. The findings were used to guide the ongoing epidemic response and recovery efforts, including health communication, social mobilization, and planning, to prevent and respond to future outbreaks or sporadic cases of Ebola. |
Facilitators and barriers to community acceptance of safe, dignified medical burials in the context of an Ebola epidemic, Sierra Leone, 2014
Lee-Kwan SH , DeLuca N , Bunnell R , Clayton HB , Turay AS , Mansaray Y . J Health Commun 2017 22 24-30 Sierra Leone was heavily affected by the Ebola epidemic, with over 14,000 total cases. Given that corpses of people who have died from Ebola are highly infectious and given the extremely high risk of Ebola transmission associated with direct contact with bodies of people who have died of Ebola, community acceptance of safe, dignified medical burials was one of the important components of efforts to stop the Ebola epidemic in Sierra Leone. Information on barriers and facilitators for community acceptance of safe, dignified medical burials is limited. A rapid qualitative assessment using focus group discussions (FGDs) explored community knowledge, attitudes, and practices towards safe and dignified burials in seven chiefdoms in Bo District, Sierra Leone. In total, 63 FGDs were conducted among three groups: women >25 years of age, men >25 years of age, and young adults 19-25 years of age. In addition to concerns about breaking cultural traditions, barriers to safe burial acceptance included concerns by family members about being able to view the burial, perceptions that bodies were improperly handled, and fear that stigma may occur if a family member receives a safe, dignified medical burial. Participants suggested that providing opportunities for community members to participate in safe and dignified burials would improve community acceptance. |
Attitudes about vaccines to prevent Ebola virus disease in Guinea at the end of a large Ebola epidemic: Results of a national household survey

Vaccine 2017 35 6915-6923 INTRODUCTION: In 2014-2016, an Ebola epidemic devastated Guinea; more than 3800 cases and 2500 deaths were reported to the World Health Organization. In August 2015, as the epidemic waned and clinical trials of an experimental, Ebola vaccine continued in Guinea and neighboring Sierra Leone, we conducted a national household survey about Ebola-related knowledge, attitudes, and practices (KAP) and opinions about "hypothetical" Ebola vaccines. METHODS: Using cluster-randomized sampling, we selected participants aged 15+ years old in Guinea's 8 administrative regions, which had varied cumulative case counts. The questionnaire assessed socio-demographic characteristics, experiences during the epidemic, Ebola-related KAP, and Ebola vaccine attitudes. To assess the potential for Ebola vaccine introduction in Guinea, we examined the association between vaccine attitudes and participants' characteristics using categorical and multivariable analyses. RESULTS: Of 6699 persons invited to participate, 94% responded to at least 1 Ebola vaccine question. Most agreed that vaccines were needed to fight the epidemic (85.8%) and that their family would accept safe, effective Ebola vaccines if they became available in Guinea (84.2%). These measures of interest and acceptability were significantly more common among participants who were male, wealthier, more educated, and lived with young children who had received routine vaccines. Interest and acceptability were also significantly higher among participants who understood Ebola transmission modes, had witnessed Ebola response teams, knew Ebola-affected persons, believed Ebola was not always fatal, and would access Ebola treatment centers. In multivariable analyses of the majority of participants living with young children, interest and acceptability were significantly higher among those living with vaccinated children than among those living with unvaccinated children. DISCUSSION: The high acceptability of hypothetical vaccines indicates strong potential for introducing Ebola vaccines across Guinea. Strategies to build public confidence in use of Ebola vaccines should highlight any similarities with safe, effective vaccines routinely used in Guinea. |
