RESUMO
Emerging infectious diseases are a growing threat in sub-Saharan African countries, but the human and technical capacity to quickly respond to outbreaks remains limited. Here, we describe the experience and lessons learned from a joint project with the WHO Regional Office for Africa (WHO AFRO) to support the sub-Saharan African COVID-19 response.In June 2020, WHO AFRO contracted a number of consultants to reinforce the COVID-19 response in member states by providing actionable epidemiological analysis. Given the urgency of the situation and the magnitude of work required, we recruited a worldwide network of field experts, academics and students in the areas of public health, data science and social science to support the effort. Most analyses were performed on a merged line list of COVID-19 cases using a reverse engineering model (line listing built using data extracted from national situation reports shared by countries with the Regional Office for Africa as per the IHR (2005) obligations). The data analysis platform The Renku Project ( https://renkulab.io ) provided secure data storage and permitted collaborative coding.Over a period of 6 months, 63 contributors from 32 nations (including 17 African countries) participated in the project. A total of 45 in-depth country-specific epidemiological reports and data quality reports were prepared for 28 countries. Spatial transmission and mortality risk indices were developed for 23 countries. Text and video-based training modules were developed to integrate and mentor new members. The team also began to develop EpiGraph Hub, a web application that automates the generation of reports similar to those we created, and includes more advanced data analyses features (e.g. mathematical models, geospatial analyses) to deliver real-time, actionable results to decision-makers.Within a short period, we implemented a global collaborative approach to health data management and analyses to advance national responses to health emergencies and outbreaks. The interdisciplinary team, the hands-on training and mentoring, and the participation of local researchers were key to the success of this initiative.

BACKGROUND: Health information systems are crucial to provide data for decision-making and demand for data is constantly growing. However, the link between data and decisions is not always rational or linear and the management of data ends up overloading frontline health workers, which may compromise quality of healthcare delivery. Despite limited evidence, there is an increasing push for the digitalization of health information systems, which poses enormous challenges, particularly in remote, rural settings in low- and middle-income countries. Paper-based tools will continue to be used in combination with digital solutions and this calls for efforts to make them more responsive to local needs. Paper-based Health Information Systems in Comprehensive Care (PHISICC) is a transdisciplinary, multi-country research initiative to create and test innovative paper-based health information systems in three sub-Saharan African countries. METHODS/DESIGN: The PHISICC initiative is being carried out in remote, rural settings in Côte d'Ivoire, Mozambique and Nigeria through partnership with ministries of health and research institutions. We began with research syntheses to acquire the most up-to-date knowledge on health information systems. These were coupled with fieldwork in the three countries to understand the current design, patterns and contexts of use, and healthcare worker perspectives. Frontline health workers, with designers and researchers, used co-creation methods to produce the new PHISICC tools. This suite of tools is being tested in the three countries in three cluster-randomized controlled trials. Throughout the project, we have engaged with a wide range of stakeholders and have maintained the highest scientific standards to ensure that results are relevant to the realities in the three countries. DISCUSSION: We have deployed a comprehensive research approach to ensure the robustness and future policy uptake of findings. Besides the innovative PHISICC paper-based tools, our process is in itself innovative. Rather than emphasizing the technical dimensions of data management, we focused instead on frontline health workers' data use and decision-making. By tackling the whole scope of primary healthcare areas rather than a subset of them, we have developed an entirely new design and visual language for a suite of tools across healthcare areas. The initiative is being tested in remote, rural areas where the most vulnerable live.

BACKGROUND: Communication can be used to generate demand for vaccination or address vaccine hesitancy, and is crucial to successful childhood vaccination programmes. Research efforts have primarily focused on communication for routine vaccination. However, vaccination campaigns, particularly in low- or middle-income countries (LMICs), also use communication in diverse ways. Without a comprehensive framework integrating communication interventions from routine and campaign contexts, it is not possible to conceptualise the full range of possible vaccination communication interventions. Therefore, vaccine programme managers may be unaware of potential communication options and researchers may not focus on building evidence for interventions used in practice. In this paper, we broaden the scope of our existing taxonomy of communication interventions for routine vaccination to include communication used in campaigns, and integrate these into a comprehensive taxonomy of vaccination communication interventions. METHODS: Building on our taxonomy of communication for routine vaccination, we identified communication interventions used in vaccination campaigns through a targeted literature search; observation of vaccination activities in Cameroon, Mozambique and Nigeria; and stakeholder consultations. We added these interventions to descriptions of routine vaccination communication and categorised the interventions according to their intended purposes, building from an earlier taxonomy of communication related to routine vaccination. RESULTS: The comprehensive taxonomy groups communication used in campaigns and routine childhood vaccination into seven purpose categories: 'Inform or Educate'; 'Remind or Recall'; 'Enhance Community Ownership'; 'Teach Skills'; 'Provide Support'; 'Facilitate Decision Making' and 'Enable Communication'. Consultations with LMIC stakeholders and experts informed the taxonomy's definitions and structure and established its potential uses. CONCLUSIONS: This taxonomy provides a standardised way to think and speak about vaccination communication. It is categorised by purpose to help conceptualise communication interventions as potential solutions to address needs or problems. It can be utilised by programme planners, implementers, researchers and funders to see the range of communication interventions used in practice, facilitate evidence synthesis and identify evidence gaps.

INTRODUCTION: Leprosy and lymphatic filariasis (LF) are among the most disabling neglected tropical diseases (NTDs) that affect the citizens of Mozambique, especially in the Northern provinces. The irreversible impairments caused by these NTDs often lead to psychosocial consequences, including poor mental wellbeing, stigma and reduced social participation. Limited data on these consequences are available for Mozambique, which are urgently needed to better understand the true disease burden and support advocacy for scaling up interventions. METHODS: A cross-sectional mixed-methods study was conducted. Mental distress was assessed with the Self Reporting Questionnaire (SRQ-20), participation restriction was assessed with the Participation Scale Short (PSS) and perceived stigma was assessed with the Explanatory Model Interview Catalogue affected persons stigma scale (EMIC-AP). Additionally, semi-structured interviews were conducted with persons affected by leprosy or LF. RESULTS: In total, 127 persons affected by leprosy and 184 persons affected by LF were included in the quantitative portion of the study. For the qualitative portion, eight semi-structured interviews were conducted. In both disease groups, mental distress was found in 70% of participants. Moreover, 80% of persons affected by leprosy and 90% of persons affected by LF perceived stigma. Moderate to extreme participation restriction was found in approximately 43% of persons affected by leprosy and in 26% of the persons affected by LF. Persons affected by leprosy and LF felt excluded from society and experienced financial problems. More severe disabilities were associated with more severe outcomes for mental wellbeing, participation restriction and stigma. By contrast, participation in a self-care group was suggested to have a positive impact on these outcomes. CONCLUSION: The findings provide evidence that persons affected by leprosy and LF must not only confront physical impairments but also experience significant disability in the psychosocial domain, including mental distress, participation restriction and stigma. These challenges must be urgently addressed by NTD programmes to promote the inclusion and wellbeing of persons affected by NTDs.

INTRODUCTION: Leprosy, or Hansen's disease, remains a cause of preventable disability. Early detection, treatment and prevention are key to reducing transmission. Post-exposure prophylaxis with single-dose rifampicin (SDR-PEP) reduces the risk of developing leprosy when administered to screened contacts of patients. This has been adopted in the WHO leprosy guidelines. The PEP4LEP study aims to determine the most effective and feasible method of screening people at risk of developing leprosy and administering chemoprophylaxis to contribute to interrupting transmission. METHODS AND ANALYSIS: PEP4LEP is a cluster-randomised implementation trial comparing two interventions of integrated skin screening combined with SDR-PEP distribution to contacts of patients with leprosy in Ethiopia, Mozambique and Tanzania. One intervention is community-based, using skin camps to screen approximately 100 community contacts per leprosy patient, and to administer SDR-PEP when eligible. The other intervention is health centre-based, inviting household contacts of leprosy patients to be screened in a local health centre and subsequently receive SDR-PEP when eligible. The mobile health (mHealth) tool SkinApp will support health workers' capacity in integrated skin screening. The effectiveness of both interventions will be compared by assessing the rate of patients with leprosy detected and case detection delay in months, as well as feasibility in terms of cost-effectiveness and acceptability. ETHICS AND DISSEMINATION: Ethical approval was obtained from the national ethical committees of Ethiopia (MoSHE), Mozambique (CNBS) and Tanzania (NIMR/MoHCDEC). Study results will be published open access in peer-reviewed journals, providing evidence for the implementation of innovative leprosy screening methods and chemoprophylaxis to policymakers. TRIAL REGISTRATION NUMBER: NL7294 (NTR7503).

INTRODUCTION: Front-line health workers in remote health facilities are the first contact of the formal health sector and are confronted with life-saving decisions. Health information systems (HIS) support the collection and use of health related data. However, HIS focus on reporting and are unfit to support decisions. Since data tools are paper-based in most primary healthcare settings, we have produced an innovative Paper-based Health Information System in Comprehensive Care (PHISICC) using a human-centred design approach. We are carrying out a cluster randomised controlled trial in three African countries to assess the effects of PHISICC compared with the current systems. METHODS AND ANALYSIS: Study areas are in rural zones of Côte d'Ivoire, Mozambique and Nigeria. Seventy health facilities in each country have been randomly allocated to using PHISICC tools or to continuing to use the regular HIS tools. We have randomly selected households in the catchment areas of each health facility to collect outcomes' data (household surveys have been carried out in two of the three countries and the end-line data collection is planned for mid-2021). Primary outcomes include data quality and use, coverage of health services and health workers satisfaction; secondary outcomes are additional data quality and use parameters, childhood mortality and additional health workers and clients experience with the system. Just prior to the implementation of the trial, we had to relocate the study site in Mozambique due to unforeseen logistical issues. The effects of the intervention will be estimated using regression models and accounting for clustering using random effects. ETHICS AND DISSEMINATION: Ethics committees in Côte d'Ivoire, Mozambique and Nigeria approved the trials. We plan to disseminate our findings, data and research materials among researchers and policy-makers. We aim at having our findings included in systematic reviews on health systems interventions and future guidance development on HIS. TRIAL REGISTRATION NUMBER: PACTR201904664660639; Pre-results.

BACKGROUND: Communication interventions for childhood vaccination are promising strategies to address vaccine hesitancy, but current research is limited by the outcomes measured. Most studies measure only vaccination-related outcomes, with minimal consideration of vaccine hesitancy-relevant intermediate outcomes. This impedes understanding of which interventions or elements are effective. It is also unknown which outcomes are important to the range of stakeholders affected by vaccine hesitancy. Outcome selection shapes the evidence base, informing future interventions and trials, and should reflect stakeholder priorities. Therefore, our aim was to identify which outcome domains (i.e. broad outcome categories) are most important to different stakeholders, identifying preliminary core outcome domains to inform evaluation of three common vaccination communication types: (i) communication to inform or educate, (ii) remind or recall, and (iii) enhance community ownership. METHODS: We conducted a two-stage online Delphi survey, involving four stakeholder groups: parents or community members, healthcare providers, researchers, and government or non-governmental organisation representatives. Participants rated the importance of eight outcome domains for each of the three communication types. They also rated specific outcomes within one domain ("attitudes or beliefs") and provided feedback about the survey. RESULTS: Collectively, stakeholder groups prioritised outcome domains differently when considering the effects of different communication types. For communication that aims to (i) inform or educate, the most important outcome domain is "knowledge or understanding"; for (ii) reminder communication, "vaccination status and behaviours"; and for (iii) community engagement communication, "community participation". All stakeholder groups rated most outcome domains as very important or critical. The highest rated specific outcome within the "attitudes or beliefs" domain was "trust". CONCLUSION: This Delphi survey expands the field of core outcomes research and identifies preliminary core outcome domains for measuring the effects of communication about childhood vaccination. The findings support the argument that vaccination communication is not a single homogenous intervention - it has a range of purposes, and vaccination communication evaluators should select outcomes accordingly.

BACKGROUND: Improved communication about childhood vaccination is fundamental to increasing vaccine uptake in low-income countries. Mozambique, with 64% of children fully vaccinated, uses a range of communication interventions to promote uptake of childhood immunisation. OBJECTIVES: Using a taxonomy developed by the 'Communicate to Vaccinate' (COMMVAC) project, the study aims to identify and classify the existing communication interventions for vaccination in Mozambique and to find the gaps. METHODS: We used a qualitative research approach to identify the range of communication interventions used in Mozambique. In-depth semi-structured interviews were carried out with key purposively selected personnel at national level and relevant documents were collected and analysed. These data were complemented with observations of communication during routine vaccination and campaigns in Nampula province. We used the COMMVAC taxonomy, which organises vaccination communication intervention according to its intended purpose and the population targeted, to map both routine and campaign interventions. RESULTS: We identified interventions used in campaign and routine vaccination, or in both, fitting five of the seven taxonomy purposes, with informing or educating community members predominating. We did not identify any interventions that aimed to provide support or facilitate decision-making. There were interventions for all main target groups, although fewer for health providers. Overlap occurred: for example, interventions often targeted both parents and community members. CONCLUSIONS: We consider that the predominant focus on informing and educating community members is appropriate in the Mozambican context, where there is a high level of illiteracy and poor knowledge of the reasons for vaccination. We recommend increasing interventions for health providers, in particular training them in better communication for vaccination. The taxonomy was useful for identifying gaps, but needs to be more user-friendly if it is to be employed as a tool by health service managers.

OBJECTIVES: We present a comprehensive taxonomy of outcomes for childhood vaccination communication interventions. Adding to our earlier map of trial outcomes, we aimed to (1) identify relevant outcomes not measured in trials, (2) identify outcomes from stakeholder focus groups, and (3) organize outcomes into a taxonomy. STUDY DESIGN AND SETTING: We identified additional outcomes from nonvaccination health communication literature and through parent and health care professional focus groups. We organized outcomes into the taxonomy through iterative discussion and informed by organizational principles established by leaders in core outcome research. RESULTS: The taxonomy includes three overarching core areas, divided into eight domains and then into outcomes. Core area one is psychosocial impact, including the domains "knowledge or understanding," "attitudes or beliefs," and "decision-making." Core area two is health impact, covering "vaccination status and behaviors" and "health status and well-being." Core area three is community, social, or health system impact, containing "intervention design and implementation," "community participation," and "resource use." CONCLUSION: To our knowledge, this taxonomy is the first attempt to conceptualize the range of potential outcomes for vaccination communication. It can be used by researchers selecting outcomes for complex communication interventions. We will also present the taxonomy to stakeholders to establish core outcome domains.

BACKGROUND: Understanding stakeholders' (parents', communities' and health workers') perspectives of communication about childhood vaccination, including their preferences for its format, delivery and content, is an important step towards designing better communication strategies and ensuring more informed parents. Our objectives were to explore stakeholders' views, experiences and preferences for childhood vaccination communication in Cameroon. METHODS: In 2014, in the Central and North West Regions of Cameron, we gathered qualitative data for our case study using the following methods: semi structured interviews; observations and informal conversations during routine immunization clinics and three rounds of the National Polio Immunization Campaign; document analysis of reports and mass media communications about vaccination; and a survey of parents. We conducted a thematic analysis of the qualitative data to identify themes relating to views, experiences and perceptions of vaccination information and its delivery. Survey data were analysed using simple descriptive statistics. RESULTS: All of the parents interviewed felt that vaccinating their child was important, and trusted the information provided by health workers. However, many parents wanted more information. Parents did not always feel that they could ask questions during vaccination appointments. All participants felt that health workers and vaccination clinics were important sources of information. Social mobilisation activities such as door-to-door visits and announcements during religious services were important and accepted ways of communicating information, especially during vaccination campaigns. Information communicated through mass media and text messages was also seen as important. In general, stakeholders believed that more consistent messaging about routine vaccination through community channels would be helpful to remind parents of the importance of routine vaccination during ongoing rounds of vaccination campaigns against polio. CONCLUSIONS: This study confirms that parents regard information about childhood vaccination as important, but that health services need to be organized in ways that prioritize and facilitate communication, particularly about routine vaccination.

BACKGROUND: Schistosomiasis is a parasitic disease which affects almost 300 million people worldwide each year. It is highly endemic in Mozambique. Prevention and control of schistosomiasis relies mainly on mass drug administration (MDA), as well as adoption of basic sanitation practices. Individual and community perceptions of schistosomiasis are likely to have a significant effect on prevention and control efforts. In order to establish a baseline to evaluate a community engagement intervention with a focus on schistosomiasis, a survey to determine knowledge, attitudes and practices relating to the disease was conducted. METHODOLOGY/PRINCIPAL FINDINGS: A representative cross-sectional household survey was carried out in four districts of Nampula province, Mozambique. Interviews were conducted in a total of 791 households, using a structured questionnaire. While awareness of schistosomiasis was high (91%), correct knowledge of how it is acquired (18%), transmitted (26%) and prevented (13%) was low among those who had heard of the disease. Misconceptions, such as the belief that schistosomiasis is transmitted through sexual contact (27%), were common. Only about a third of those who were aware of the disease stated that they practiced a protective behaviour and only a minority of those (39%) reported an effective behaviour. Despite several rounds of MDA for schistosomiasis in the recent past, only a small minority of households with children reported that at least one of them had received a drug to treat the disease (9%). CONCLUSION/SIGNIFICANCE: Poor knowledge of the causes of schistosomiasis and how to prevent it, coupled with persisting misconceptions, continue to pose barriers to effective disease prevention and control. To achieve high levels of uptake of MDA and adoption of protective behaviours, it will be essential to engage individuals and communities, improving their understanding of the causes and symptoms of schistosomiasis, recommended prevention mechanisms and the rationale behind MDA.

OBJECTIVES: The objectives of this article are to (1) comprehensively catalog outcomes measured in trials of childhood vaccination communication interventions and (2) analyze patterns and trends in outcome selection. To achieve these objectives, we developed a Trial Outcomes Map for vaccination communication. STUDY DESIGN: We searched the Cochrane Central Register of Controlled Trials for trials of childhood vaccination communication interventions, extracting verbatim all outcome information from included trials. Through thematic grouping, we categorized outcomes based on conceptual similarities, forming a Trial Outcomes Map. RESULTS: We identified 112 relevant trials containing 209 outcomes. Thematic analysis revealed three overarching Outcome Categories: consumer-, vaccination-, and health system-related outcomes. These categories contain 21 Outcome Types (eg, "knowledge," "cost"), measured using 66 different Outcome Variables. Vaccination outcomes were measured most frequently and health system-related outcomes least frequently. Consumer outcomes are increasingly measured in more recent trials. CONCLUSION: The number of measures used for the same outcomes complicates data synthesis and interpretation. Despite recent trends toward including consumer outcomes, intermediate outcome measurement is lacking, hampering understanding of how and why vaccination communication interventions do or do not work. This Map may improve outcome consistency in future trials and will contribute to a forthcoming core outcome set.

The aim of this study was to contribute to the better planning of measles elimination actions in Mozambique, by considering the impact of vaccination actions over the period 2000 to 2011. Descriptive and ecological studies and case records made available by the Ministry of Health were used to analyze measles vaccination coverage. Statistical analysis was performed using time series and spatial analysis. Vaccine coverage rates ranged from 82% to 99%. Coverage rates in Maputo city were under 70% and in Niassa province they were over 100%. Coverage showed a clustered pattern in the districts. The measles incidence rate was 1.58 per 100,000 inhabitants (0.00-40.08 per 100,000 inhabitants); districts bordering neighboring countries presented high incidence rates. Although measles morbidity and mortality has decreased in Mozambique, vaccine coverage has been insufficient to interrupt measles transmission. Enhanced surveillance, including investigation of cases and outbreaks, and improvements in measles vaccination are recommended in order to achieve a homogenous coverage rate of ≥ 95% for both routine and mass vaccination campaigns.

O objetivo deste estudo foi analisar as ações de eliminação do sarampo em Moçambique, considerando o impacto do programa de vacinação ao longo do período de 2000-2011. Foram revisados os dados de vacinação e os casos de sarampo disponíveis no Ministério da Saúde. Análise de séries temporais e técnicas estatísticas de análise espacial foram aplicadas. As coberturas variaram entre 82% e 99%. Nas províncias, a cidade de Maputo teve as coberturas abaixo de 70%, e a província de Niassa teve as coberturas acima de 100%. As coberturas apresentaram um padrão espacial que se modificou com o tempo. A taxa de incidência de sarampo no país foi de 1,58 (0,00-40,08 distritos) por 100 mil habitantes. Os distritos que fazem fronteiras com os países vizinhos tiveram as elevadas taxas de incidência. As coberturas de rotina são insuficientes, e a circulação de sarampo continua em Moçambique. O país necessita alcançar coberturas homogêneas e maiores que 95% em crianças menores de um ano, manter as campanhas de vacinação e melhorar a vigilância e o tratamento de casos.

O sarampo e a rubéola são doenças infectocontagiosas causadas por vírus, para as quais existem vacinas eficazes para o seu controle e eliminação. O objetivo do presente trabalho foianalisar os dados de sarampo e rubéola e as ações de controle dessas doenças em Moçambique. Foram utilizadas três fontes de dados: Sistema de informação do Ministério da Saúde de Moçambique, inquérito de mães e responsáveis de crianças nas unidades sanitárias edados do estudo HTLV-1 realizado pelo Instituto Nacional de Saúde. Foi realizada análise espacial para as coberturas de vacinação e incidência de sarampo. Também foram descritoscasos de sarampo e rubéola confirmados no período de 2006 até 2010 e compararam-se as prevalências de soropositividade para sarampo e rubéola em crianças HIV positiva e HIV negativas. Os resultados indicam que a vacinação e a vigilância de sarampo têm um progresso assinalável no país, mas essas atividades ainda mostram-se insuficientes para eliminar a doença. Para rubéola, o país não tem ações específicas de controle. A prevalência de soropositividade de sarampo foi de 30 por cento em crianças HIV positivas e 87 por cento em crianças HIV negativas; a soropositividade da rubéola foi de 47 por cento para o grupo de crianças HIV positivas e 4 por cento em crianças HIV negativas. As crianças infectadas por HIV eram mais suscetíveis a infecção de sarampo em relação ao grupo de crianças HIV negativas, e os distritos localizados nas fronteiras tiveram as taxas de incidência de sarampo mais elevadas. Recomendações: 1) Implantar a vigilância de casos de Síndrome de Rubéola Congênita. 2) Incluir a rubéola no sistema de vigilância epidemiológica. 3) Introduzir a vacina contra rubéola no calendário de vacinação. 4) Incluir crianças a partir de 6 meses de idade na vacinação em massa contra sarampo. 5) Formar e capacitacitar o pessoal envolvido nas atividades de vacinação. 6) Estabelecer mecanismos de identificação de grupos vulneráveis para sarampo e definir ações específicas para reduzir o risco de infecção. 7) Melhorar a qualidade dos dados do sistema deinformação verificando se são completos, corretos e oportunos. 8) Promover o uso dos dados para tomadas de decisão, particularmente ao nível local. 9) Reforçar a mobilização social para a vacinação de rotina.
