Public perceptions of Ebola vaccines and confidence in health services to treat Ebola, malaria, and tuberculosis: Findings from a cross-sectional household survey in Uganda, 2020.

Uganda used Ebola vaccines as part of its preparedness and response during the 2018-2020 10th Ebola virus disease (EVD) outbreak in neighboring Democratic Republic of the Congo (DRC). We evaluated the public's perceptions of Ebola vaccines and compared their confidence in health services to treat Ebola versus malaria and tuberculosis as part of a survey on Ebola knowledge, attitudes, and practices (KAP) conducted in March 2020. A cross-sectional household survey was implemented in six districts in Uganda using multi-stage cluster sampling to randomly select participants. The districts were purposively selected from districts classified by the government as at high- or low-risk for an EVD outbreak. We describe perceptions of Ebola vaccines and confidence in health services to treat Ebola, tuberculosis, and malaria. Modified Poisson regression modeling was used to identify the demographic correlates of these outcomes. Among 3,485 respondents, 18% were aware of Ebola vaccines. Of those, 92% agreed that the vaccines were needed to prevent Ebola. Participants aged 15-24 years were 4% more likely to perceive such need compared to those 60 years and older (adjusted prevalence ratio [aPR] 1.04, 95% confidence interval [CI] 1.0-1.08). The perceived need was 5% lower among participants with at least some secondary education compared to uneducated participants (aPR 0.95; 0.92-0.99). Overall, 81% of those aware of the vaccines believed that everyone or most people in their community would get vaccinated if offered, and 94% said they would likely get vaccinated if offered. Confidence in health services to treat Ebola was lower compared to treating malaria or tuberculosis (55% versus 93% and 77%, respectively). However, participants from the EVD high-risk districts were 22% more likely to be confident in health services to treat Ebola compared to those in low-risk districts (aPR: 1.22; 95% CI: 1.08, 1.38). Our findings suggest that intent to take an Ebola vaccine during an outbreak was strong, but more work needs to be done to increase public awareness of these vaccines. The public's high confidence in health services to treat other health threats, such as malaria and tuberculosis, offer building blocks for strengthening their confidence in health services to treat EVD in the event of an outbreak.

SARS-CoV-2 case detection using community event-based surveillance system-February-September 2020: lessons learned from Senegal.

The COVID-19 pandemic necessitated the rapid development and implementation of effective surveillance systems to detect and respond to the outbreak in Senegal. In this documentation, we describe the design and implementation of the Community Event-Based Surveillance (CEBS) system in Senegal to strengthen the existing Integrated Disease Surveillance and Response system. The CEBS system used a hotline and toll-free number to collect and triage COVID-19-related calls from the community. Data from the CEBS system were integrated with the national system for further investigation and laboratory testing. From February to September 2020, a total of 10 760 calls were received by the CEBS system, with 10 751 calls related to COVID-19. The majority of calls came from the Dakar region, which was the epicentre of the outbreak in Senegal. Of the COVID-19 calls, 50.2% were validated and referred to health districts for further investigation, and 25% of validated calls were laboratory-confirmed cases of SARS-CoV-2. The implementation of the CEBS system allowed for timely detection and response to potential COVID-19 cases, contributing to the overall surveillance efforts in the country. Lessons learned from this experience include the importance of decentralised CEBS, population sensitisation on hotlines and toll-free usage, and the potential role of Community Health Workers in triaging alerts that needs further analysis. This experience highlights the contribution of a CEBS system in Senegal and provides insights into the design and operation of such a system. The findings can inform other countries in strengthening their surveillance systems and response strategies.

CDC's COVID-19 International Vaccine Implementation and Evaluation Program and Lessons from Earlier Vaccine Introductions.

The US Centers for Disease Control and Prevention (CDC) supports international partners in introducing vaccines, including those against SARS-CoV-2 virus. CDC contributes to the development of global technical tools, guidance, and policy for COVID-19 vaccination and has established its COVID-19 International Vaccine Implementation and Evaluation (CIVIE) program. CIVIE supports ministries of health and their partner organizations in developing or strengthening their national capacities for the planning, implementation, and evaluation of COVID-19 vaccination programs. CIVIE's 7 priority areas for country-specific technical assistance are vaccine policy development, program planning, vaccine confidence and demand, data management and use, workforce development, vaccine safety, and evaluation. We discuss CDC's work on global COVID-19 vaccine implementation, including priorities, challenges, opportunities, and applicable lessons learned from prior experiences with Ebola, influenza, and meningococcal serogroup A conjugate vaccine introductions.

Evaluation of Community Perceptions and Prevention Practices Related to Ebola Virus as Part of Outbreak Preparedness in Uganda, 2020.

INTRODUCTION: During the 2018-2020 Ebola virus disease (EVD) outbreak in the Democratic Republic of the Congo, risk communication and community engagement (RCCE) were prioritized in geographic areas in Uganda considered at high risk of introduction of EVD. To inform EVD preparedness in Uganda, we evaluated community perceptions and prevention practices related to EVD in 6 districts in Uganda. METHODS: In March 2020, we conducted a population-based survey in 6 purposively selected districts in Uganda using multistage cluster sampling. We examined differences between districts classified as high- versus low risk for EVD in terms of their message exposure from RCCE; risk perception; and EVD knowledge, attitudes, and prevention practices. RESULTS: A total of 3,485 respondents were interviewed (91% response rate). EVD message exposure was more common in the high- versus low-risk districts. EVD risk perceptions were low overall but greater in the high- versus low-risk districts. Comprehensive knowledge was significantly greater in the high- versus low-risk districts (adjusted prevalence ratio [aPR] 1.61, 95% confidence interval [CI]=1.35, 1.93). Respondents' engagement in all 3 EVD prevention practices (frequent handwashing with soap, avoiding physical contact with suspected Ebola patients, and avoiding burials involving contact with a corpse) was very low (4%). However, respondents with comprehensive knowledge were more likely to engage in all 3 EVD prevention practices compared to respondents without comprehensive knowledge (aPR 1.87, 95% CI=1.08, 3.25). CONCLUSION: Our findings suggest that while RCCE efforts as part of EVD outbreak preparedness may have contributed to higher EVD knowledge in the targeted high-risk districts, uptake of prevention behaviors was similarly low across districts. In a non-outbreak setting, implementing targeted RCCE strategies may not be sufficient to motivate people to adopt protective behaviors in the absence of a high threshold of perceived threat such as in an active outbreak.

SARS-CoV-2 infection risk among vaccinated and unvaccinated household members during the Alpha variant surge - Denver, Colorado, and San Diego, California, January-April 2021.

BACKGROUND: COVID-19 vaccination reduces SARS-CoV-2 infection and transmission. However, evidence is emerging on the degree of protection across variants and in high-transmission settings. To better understand the protection afforded by vaccination specifically in a high-transmission setting, we examined household transmission of SARS-CoV-2 during a period of high community incidence with predominant SARS-CoV-2 B.1.1.7 (Alpha) variant, among vaccinated and unvaccinated contacts. METHODS: We conducted a household transmission investigation in San Diego County, California, and Denver, Colorado, during January-April 2021. Households were enrolled if they had at least one person with documented SARS-CoV-2 infection. We collected nasopharyngeal swabs, blood, demographic information, and vaccination history from all consenting household members. We compared infection risks (IRs), RT-PCR cycle threshold values, SARS-CoV-2 culture results, and antibody statuses among vaccinated and unvaccinated household contacts. RESULTS: We enrolled 493 individuals from 138 households. The SARS-CoV-2 variant was identified from 121/138 households (88%). The most common variants were Alpha (75/121, 62%) and Epsilon (19/121, 16%). There were no households with discordant lineages among household members. One fully vaccinated secondary case was symptomatic (13%); the other 5 were asymptomatic (87%). Among unvaccinated secondary cases, 105/108 (97%) were symptomatic. Among 127 households with a single primary case, the IR for household contacts was 45% (146/322; 95% Confidence Interval [CI] 40-51%). The observed IR was higher in unvaccinated (130/257, 49%, 95% CI 45-57%) than fully vaccinated contacts (6/26, 23%, 95% CI 11-42%). A lower proportion of households with a fully vaccinated primary case had secondary cases (1/5, 20%) than households with an unvaccinated primary case (66/108, 62%). CONCLUSIONS: Although SARS-CoV-2 infections in vaccinated household contacts were reported in this high transmission setting, full vaccination protected against SARS-CoV-2 infection. These findings further support the protective effect of COVID-19 vaccination and highlight the need for ongoing vaccination among eligible persons.

WHO competency framework for health authorities and institutions to manage infodemics: its development and features.

BACKGROUND: In April 2020, the World Health Organization (WHO) Information Network for Epidemics produced an agenda for managing the COVID-19 infodemic. "Infodemic" refers to the overabundance of information-including mis- and disinformation. In this agenda it was pointed out the need to create a competency framework for infodemic management (IM). This framework was released by WHO on 20th September 2021. This paper presents the WHO framework for IM by highlighting the different investigative steps behind its development. METHODS: The framework was built through three steps. Step 1 included the preparatory work following the guidelines in the Guide to writing Competency Framework for WHO Academy courses. Step 2 was based on a qualitative study with participants (N = 25), identified worldwide on the basis of their academic background in relevant fields of IM or of their professional experience in IM activities at the institutional level. The interviews were conducted online between December 2020 and January 2021, they were video-recorded and analyzed using thematic analysis. In Step 3, two stakeholder panels were conducted to revise the framework. RESULTS: The competency framework contains four primary domains, each of which comprised main activities, related tasks, and knowledge and skills. It identifies competencies to manage and monitor infodemics, to design, conduct and evaluate appropriate interventions, as well as to strengthen health systems. Its main purpose is to assist institutions in reinforcing their IM capacities and implementing effective IM processes and actions according to their individual contexts and resources. CONCLUSION: The competency framework is not intended to be a regulatory document nor a training curriculum. As a WHO initiative, it serves as a reference tool to be applied according to local priorities and needs within the different countries. This framework can assist institutions in strengthening IM capacity by hiring, staff development, and human resources planning.

Behaviors Associated With Household Transmission of SARS-CoV-2 in California and Colorado, January 2021-April 2021.

Introduction: Mitigation behaviors are key to preventing SARS-CoV-2 transmission. We identified the behaviors associated with secondary transmission from confirmed SARS-CoV-2 primary cases to household contacts and described the characteristics associated with reporting these behaviors. Methods: Households with confirmed SARS-CoV-2 infections were recruited in California and Colorado from January to April 2021. Self-reported behaviors and demographics were collected through interviews. We investigated behaviors associated with transmission and individual and household characteristics associated with behaviors using univariable and multivariable logistic regression with generalized estimating equations to account for household clustering. Results: Among household contacts of primary cases, 43.3% (133 of 307) became infected with SARS-CoV-2. When an adjusted analysis was conducted, household contacts who slept in the same bedroom with the primary case (AOR=2.19; 95% CI=1.25, 3.84) and ate food prepared by the primary case (AOR=1.98; 95% CI=1.02, 3.87) had increased odds of SARS-CoV-2 infection. Household contacts in homes ≤2,000 square feet had increased odds of sleeping in the same bedroom as the primary case compared with those in homes >2,000 square feet (AOR=3.97; 95% CI=1.73, 9.10). Parents, siblings, and other relationships (extended family, friends, or roommates) of the primary case had decreased odds of eating food prepared by the primary case compared with partners. Conclusions: Sleeping in the same bedroom as the primary case and eating food prepared by the primary case were associated with secondary transmission. Household dimension and relationship to the primary case were associated with these behaviors. Our findings encourage innovative means to promote adherence to mitigation measures that reduce household transmission.

Behaviour adoption approaches during public health emergencies: implications for the COVID-19 pandemic and beyond.

Human behaviour will continue to play an important role as the world grapples with public health threats. In this paper, we draw from the emerging evidence on behaviour adoption during diverse public health emergencies to develop a framework that contextualises behaviour adoption vis-à-vis a combination of top-down, intermediary and bottom-up approaches. Using the COVID-19 pandemic as a case study, we operationalise the contextual framework to demonstrate how these three approaches differ in terms of their implementation, underlying drivers of action, enforcement, reach and uptake. We illustrate how blended strategies that include all three approaches can help accelerate and sustain protective behaviours that will remain important even when safe and effective vaccines become more widely available. As the world grapples with the COVID-19 pandemic and prepares to respond to (re)emerging public health threats, our contextual framework can inform the design, implementation, tracking and evaluation of comprehensive public health and social measures during health emergencies.

Data on the implementation of VaxTrac electronic immunization registry in Sierra Leone.

Following the piloting of VaxTrac, an electronic immunization registry (EIR), we conducted a rapid assessment in November-December 2017 to evaluate the use of the EIR in 10 health facilities in Western Area Urban district in Sierra Leone [1]. In this data-in-brief report, we provide additional descriptive data from the assessment of the VaxTrac EIR in Sierra Leone. The assessment comprised aggregate data on vaccine doses administered that were abstracted from VaxTrac and three paper-based sources (daily tally sheets, register of children under the age of 2 years, and a summary form of doses administered). Data were abstracted for the following six vaccine doses in the immunization schedule in Sierra Leone: 1) Bacillus Calmette-Guérin vaccine, 2) first dose of pentavalent vaccine, 3) second dose of pentavalent vaccine, 4) third dose of pentavalent vaccine, 5) first dose of measles-containing vaccine, and 6) second dose of measles-containing vaccine. We descriptively analysed the abstracted data to examine the congruity between VaxTrac records and the three paper-based sources. Bar graphs were generated to visually depict the variations in number of administered vaccine doses by data source for each health facility. We provide the aggregated data for each vaccine dose abstracted by data source from each health facility as supplemental material (Excel file). The supplementary data reveal patterns in the congruity of vaccine doses captured that have implications for policy and programmatic decisions regarding the use of VaxTrac and other similar EIRs in low resource urban settings.

Assessment of VaxTrac electronic immunization registry in an urban district in Sierra Leone: Implications for data quality, defaulter tracking, and policy.

BACKGROUND: In 2016, the Sierra Leone Ministry of Health and Sanitation (MoHS) piloted VaxTrac, an electronic immunization registry (EIR), in an urban district to improve management of vaccination records and tracking of children who missed scheduled doses. We aimed to document lessons learned to inform decision-making on VaxTrac and similar EIRs' future use. METHODS: Ten out of 50 urban health facilities that implemented VaxTrac were purposively selected for inclusion in a rapid mixed-method assessment from November to December 2017. For a one-month period, records of six scheduled vaccine doses among children < 2 years old in VaxTrac were abstracted and compared to three paper-based records (register of under-two children, daily tally sheet, and monthly summary form). We used the under-two register as the reference gold standard for comparison purposes. We interviewed and observed 10 heath workers, one from each selected facility, who were using VaxTrac. RESULTS: Overall, VaxTrac captured < 65% of the vaccine doses reported in the paper-based sources, but in the largest health facility VaxTrac captured the highest number of doses. Two additional notable patterns emerged: 1) the aggregated data sources reported higher doses administered compared to the under-two register and VaxTrac; 2) data sources that need real-time data capture during the vaccination session reported fewer doses administered compared to the monthly HF2 summary form. Health workers expressed that the EIR helped them to shorten the time to manage, summarize, and report vaccination records. Workflows for data entry in VaxTrac were inconsistent among facilities and rarely integrated into existing processes. Data sharing restrictions contributed to duplicate records. CONCLUSION: Although VaxTrac helped to shorten the time to manage, summarize, and report vaccination records, data sharing restrictions coupled with inconsistent and inefficient workflows were major implementation challenges. Readiness-to-introduce and sustainability should be carefully considered before implementing an EIR.

Evidence of behaviour change during an Ebola virus disease outbreak, Sierra Leone.

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.

Considerations for the development and implementation of electronic immunization registries in Africa.

While paper-based immunization registries are the prevalent form of documenting individual-level immunization service delivery in Africa, some countries are interested in transitioning to electronic immunization registries (EIRs) which have the potential to transform immunization data into useable information for decision making to optimize the performance of immunization programs. This report discusses opportunities and challenges in the adoption of EIRs in the African continent.

Assessment of select electronic health information systems that support immunization data capture - Kenya, 2017.

BACKGROUND: Although electronic health information systems (EHIS) with immunization components exist in Kenya, questions and concerns remain about their use and alignment with the Kenya Ministry of Health's (MOH) National Vaccine and Immunization Program (NVIP). This article reports on the findings of an assessment of select EHIS with immunization components in Kenya, specifically related to system design, development, and implementation. METHODS: We conducted a rapid assessment of select EHIS with immunization components in Kenya from January to May 2017 to understand the design, development, implementation of the EHIS including the lessons learned from their use. We also assessed how the data elements in the EHIS compared to the data elements in the Maternal and Child Health Booklet used in the existing paper based system in Kenya. RESULTS: The EHIS reviewed varied in purpose, content, and population covered. Only one system was built to focus specifically on immunization data. Substantial differences in system functionality and immunization-related data elements included in the EHIS were identified. None of the EHIS had all the data elements necessary to fully replace or operate independently from the standardized paper-based system for recording immunization data in Kenya. CONCLUSIONS: Overall, the findings of this assessment highlighted substantial variation in the EHIS with immunization components. The findings provide insights and lessons learned for the Kenya MOH NVIP, immunization partners, vendors of EHIS, and users of EHIS to consider as Kenya transitions from paper-based to electronic immunization information systems.

The role of religion and spirituality in coping with type 2 diabetes: a qualitative study among Black men.

Religion and spirituality are instrumental to coping with health; however, there is limited literature on the use of religion and spirituality among Black men with type 2 diabetes. The purpose of this study is to explore how Black men use religion or spirituality to cope with diabetes management. We conducted in-depth interviews with 30 Black men recruited from a diabetes clinic in Atlanta, Georgia as part of a larger study. This article reports on data from 12 of the 30 Black men who reported the use of religion and spirituality as a coping strategy for diabetes management. The following coping strategies were reported: prayer and belief in God, keeping me alive, turning things over to God, changing my unhealthy behaviors, supplying my needs, reading the Bible, and religious or spiritual individuals helping me. Healthcare professionals and researchers involved in diabetes management among Black men should consider these findings in their efforts.

The public health role in the primary prevention of diabetes: recommendations from the chronic disease directors' project.

AIM: The article reports on the recommendations from the Diabetes Primary Prevention Project that was initiated and funded by the Division of Diabetes Translation, Centers for Disease Control and Prevention, and developed by the National Association of Chronic Disease Directors. METHOD: Essential components of statewide programs are delineated for effective interventions for diabetes primary prevention. The recommendations were derived from a structured process that is detailed on the basis of a cross-comparison of state-level diabetes prevention initiatives in six states where such programs were most developed. RESULTS: The recommendations focus on state-level partnerships, statewide program planning, required resources, policies, benchmarks for progress, and data collection. CONCLUSION: Illustrations are provided regarding how the project influenced the six participating states in further developing their programs for the primary prevention of diabetes.

The challenges of addressing primary prevention of diabetes: a response to recommendations from the chronic disease directors' project.

The growing burden of diabetes in the United States is leading public health entities to reconsider the focus of their efforts to prevent and control the disease. In particular, they are striving to include primary prevention in their agendas. Many program reports and projects, specifically the chronic disease directors project, recommend effective ways to prevent diabetes. Science supports the need for primary prevention of diabetes, but the most effective ways to implement the chronic disease directors project's recommendations remain unclear. The purpose of this commentary is to review the programmatic challenges faced by a federal diabetes public health entity, the Division of Diabetes Translation. These include limited funding, little coordination of primary prevention efforts among disease-oriented programs, limited research on effective interventions, and the large population at risk for developing diabetes. We discuss these challenges with reference to the primary prevention of diabetes, but they have broader implications for the different public health entities (federal, state, and nongovernmental organizations) with a vested interest in diabetes because they attempt to implement similar primary prevention recommendations for other diseases.

Understanding "masculinity" and the challenges of managing type-2 diabetes among African-American men.

African-American men bear a greater burden of type-2 diabetes and its associated complications. The purpose of this analysis was to explore in greater depth themes that emerged in illness narratives of a small sample of African-American men living with type-2 diabetes. The primary theme that is the focus of this article is the lived experience of black manhood and masculinity and its intersection with the challenges of diabetes self-management. In-depth interviews with 16 African-American men who had established type-2 diabetes yielded thematic analyses of four questions: (1) What do you fear most about having diabetes? (2) In what ways have people in your life treated you differently after learning you have diabetes? (3) In what ways has knowing you have diabetes affected the way you see yourself? and (4) What are some reactions when you tell people you have diabetes? This preliminary study suggests that the requirements of diabetes self-management often run counter to the traditional sex roles and learned behaviors of African-American men, and this can contribute to nonadherence to medications and poor glycemic control. Gender identity is a key cultural factor that influences health-related behaviors, including how men with type-2 diabetes engage with the healthcare system and manage their diabetes. Understanding African-American men's gender identity is an important component of cultural competency for physicians and can be consequential in patient outcomes.

The psychosocial aspects of diabetes care. Using collaborative care to manage older adults with diabetes.

Diabetes is a chronic disease that requires managing medications, adhering to dietary requirements, and engaging in age- and abilities appropriate physical activity. This article addresses the need for a collaborative care management approach that emphasizes a partnership between older adults and health care professionals. Such an approach recognizes that patients are the experts about their lives and primary care providers are experts about diabetes. A collaborative care management approach can help primary care providers assist older adults to address psychosocial concerns, cognitive functioning, and depression. We conclude this article with a brief discussion regarding a transdisciplinary approach that takes the collaborative care management approach one step further.
