Abstract
With the coronavirus disease 2019 (COVID-19) pandemic showing no signs of abating, resuming neglected tropical disease (NTD) activities, particularly mass drug administration (MDA), is vital. Failure to resume activities will not only enhance the risk of NTD transmission, but will fail to leverage behaviour change messaging on the importance of hand and face washing and improved sanitation-a common strategy for several NTDs that also reduces the risk of COVID-19 spread. This so-called "hybrid approach" will demonstrate best practices for mitigating the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by incorporating physical distancing, use of masks, and frequent hand-washing in the delivery of medicines to endemic communities and support action against the transmission of the virus through water, sanitation and hygiene interventions promoted by NTD programmes. Unless MDA and morbidity management activities resume, achievement of NTD targets as projected in the WHO/NTD Roadmap (2021-2030) will be deferred, the aspirational goal of NTD programmes to enhance universal health coverage jeopardised and the call to 'leave no one behind' a hollow one. We outline what implementing this hybrid approach, which aims to strengthen health systems, and facilitate integration and cross-sector collaboration, can achieve based on work undertaken in several African countries.

Abstract
BACKGROUND Community drug distributors or neglected tropical disease (NTD) volunteers have played a crucial role in ensuring the success of mass drug administration (MDA) programs using preventive chemotherapy (PC) for lymphatic filariasis, onchocerciasis, schistosomiasis, trachoma and soil transmitted helminths. In recent years however, a noticeable decline in motivation of some of these volunteers has been perceived, potentially negatively impacting the success of these programs. Potential hypotheses for this change in motivation include the long duration of many MDA programs, the change in sociocultural environments as well as the changes to the programs over time. This literature review identifies factors that affect NTD volunteer performance and motivation, which may be used to influence and improve future programming. METHODOLOGY/PRINCIPAL FINDINGS A systematic search was conducted to identify studies published between January 1995 and September 2016 that investigate factors pertaining to volunteer motivation and performance in NTD drug distribution programs. Searches from several databases and grey literature yielded 400 records, of which 28 articles from 10 countries met the inclusion criteria. Quality assessment of studies was performed using the Critical Appraisal Skills Programme(CASP) checklist. Data pertaining to motivation, performance, retention and satisfaction was extracted and examined for themes. Recurring themes in the literature included monetary and material incentives, intrinsic motivation, gender, cost to participate, and health systems and community support. Of these, community support and the health system were found to be particularly impactful. Very few studies were found to explicitly look at novel incentives for volunteers and very few studies have considered the out of pocket and opportunity costs that NTD volunteers bear carrying out their tasks. CONCLUSIONS/SIGNIFICANCE There is currently great interest in incorporating more attractive incentive schemes for NTD volunteers. However, our results show that the important challenges that volunteers face (cultural, health systems, financial and community related) may have less to do with financial incentives and may actually have a larger impact on their motivation than has previously been understood. Further integration of NTD programs into existing health systems is expected to improve the NTD volunteer working environment. Relevant community engagement related to the MDA program should also provide the supportive environment needed in the community to support NTD volunteers. Programs need to consider these issues to improve working conditions for NTD volunteers.

Abstract
Background Community capability is the combined influence of a community’s social systems and collective resources that can address community problems and broaden community opportunities. We frame it as consisting of three domains that together support community empowerment: what communities have; how communities act; and for whom communities act. We sought to further understand these domains through a secondary analysis of a previous systematic review on community participation in health systems interventions in low and middle income countries (LMICs). Methods We searched for journal articles published between 2000 and 2012 related to the concepts of “community”, “capability/participation”, “health systems research” and “LMIC.” We identified 64 with rich accounts of community participation involving service delivery and governance in health systems research for thematic analysis following the three domains framing community capability. Results When considering what communities have, articles reported external linkages as the most frequently gained resource, especially when partnerships resulted in more community power over the intervention. In contrast, financial assets were the least mentioned, despite their importance for sustainability. With how communities act, articles discussed challenges of ensuring inclusive participation and detailed strategies to improve inclusiveness. Very little was reported about strengthening community cohesiveness and collective efficacy despite their importance in community initiatives. When reviewing for whom communities act, the importance of strong local leadership was mentioned frequently, while conflict resolution strategies and skills were rarely discussed. Synergies were found across these elements of community capability, with tangible success in one area leading to positive changes in another. Access to information and opportunities to develop skills were crucial to community participation, critical thinking, problem solving and ownership. Although there are many quantitative scales measuring community capability, health systems research engaged with community participation has rarely made use of these tools or the concepts informing them. Overall, the amount of information related to elements of community capability reported by these articles was low and often of poor quality. Conclusions Strengthening community capability is critical to ensuring that community participation leads to genuine empowerment. Our simpler framework to define community capability may help researchers better recognize, support and assess it.

Abstract
Le Programme Africain de lutte contre l'Onchocercose (APOC) fut lancé en 1995, comme complément au brillant programme de lutte contre l'onchocercose en Afrique de l'Ouest. En 2011, plus de 80 millions de personnes ont bénéficié de cette intervention grâce à la contribution de 268 718 Distributeurs Communautaires (DC). Ses résultats significatifs occultent le rôle des femmes DC dans cette lutte cette maladie. L'objectif de cette analyse est de déterminer la contribution des femmes DC dans le traitement de l'onchocercose sous directive communautaire en Afrique sub-saharienne, et d’évaluer leur acceptation dans ledit programme. Comme stratégie de recherche, nous avons identifié toutes les études pertinentes de Janvier 1995 à Décembre 2012. Des recherches ont été effectuées dans les bases de données suivantes: Medline, Embase (Excerpta Medica Database), CINAHL (Cumulative Index to Nursing and Allied Health Literature), LILAS (Latin American and Caribbean Literature on Health Sciences). Nous avons également consulté les sites d'APOC et de l'OMS AFRO. Deux auteurs ont indépendamment évalué la pertinence des articles potentiels à l'aide des critères d'inclusion et d'exclusion bien définis. Six (6) des 25 études ont rempli les critères d'inclusion. Une étude a montré que 81% des populations où il y avait des femmes DC ont reçu l'Ivermectine par rapport à 78% des villages où n'exerçaient pas de femmes DC. Une autre étude a montré qu'il y a eu une prise de conscience croissante dans les IDC en faveur de l'acceptation de la participation des femmes à la distribution communautaire de l'Ivermectine. De plus, 70% des membres de la communauté interrogés dans certaines zones endémiques, ont déclaré que les femmes étaient plus engagées, persuasives et plus patientes que les hommes dans la distribution de l'Ivermectine. Au terme de cette étude, les évaluations qui ont été effectuées donnent à penser que les femmes peuvent jouer un rôle important dans la lutte contre l'onchocercose. Toutefois, des préoccupations subsistent quant aux considérations de mise en œuvre en faveur dudit rôle. Les conclusions ont aussi des implications pour la recherche future sur l’élaboration d'un cadre d’évaluation et de comparaison des interventions impliquant les DCs hommes et femmes.

Abstract
BACKGROUND Community participation is a major principle of people centered health systems, with considerable research highlighting its intrinsic value and strategic importance. Existing reviews largely focus on the effectiveness of community participation with less attention to how community participation is supported in health systems intervention research. OBJECTIVE To explore the extent, nature and quality of community participation in health systems intervention research in low- and middle-income countries. METHODOLOGY We searched for peer-reviewed, English language literature published between January 2000 and May 2012 through four electronic databases. Search terms combined the concepts of community, capability/participation, health systems research and low- and middle-income countries. The initial search yielded 3,092 articles, of which 260 articles with more than nominal community participation were identified and included. We further excluded 104 articles due to lower levels of community participation across the research cycle and poor description of the process of community participation. Out of the remaining 160 articles with rich community participation, we further examined 64 articles focused on service delivery and governance within health systems research. RESULTS Most articles were led by authors in high income countries and many did not consistently list critical aspects of study quality. Articles were most likely to describe community participation in health promotion interventions (78%, 202/260), even though they were less participatory than other health systems areas. Community involvement in governance and supply chain management was less common (12%, 30/260 and 9%, 24/260 respectively), but more participatory. Articles cut across all health conditions and varied by scale and duration, with those that were implemented at national scale or over more than five years being mainstreamed by government. Most articles detailed improvements in service availability, accessibility and acceptability, with fewer efforts focused on quality, and few designs able to measure impact on health outcomes. With regards to participation, most articles supported community's in implementing interventions (95%, n = 247/260), in contrast to involving communities in identifying and defining problems (18%, n = 46/260). Many articles did not discuss who in communities participated, with just over a half of the articles disaggregating any information by sex. Articles were largely under theorized, and only five mentioned power or control. Majority of the articles (57/64) described community participation processes as being collaborative with fewer describing either community mobilization or community empowerment. Intrinsic individual motivations, community-level trust, strong external linkages, and supportive institutional processes facilitated community participation, while lack of training, interest and information, along with weak financial sustainability were challenges. Supportive contextual factors included decentralization reforms and engagement with social movements. CONCLUSION Despite positive examples, community participation in health systems interventions was variable, with few being truly community directed. Future research should more thoroughly engage with community participation theory, recognize the power relations inherent in community participation, and be more realistic as to how much communities can participate and cognizant of who decides that.

Abstract
Background Lymphoedema and hydrocoele are the two most common clinical manifestations of lymphatic filariasis (LF). In order to effectively target morbidity management strategies, more information is rapidly needed on morbidity burden across all endemic countries. The purpose of this study was to develop and test an SMS tool (MeasureSMS) which enables trained community-based health workers to report basic information on all cases they identified. Methods The tool was trialled in Chikwawa district, Malawi and Ahanta West district, Ghana in 2014. Salaried health surveillance assistants (HSAs) identified and reported cases in Malawi whereas volunteer community health workers (CHWs) were used in Ghana. Health workers were trained in recognising lymphoedema and hydrocoeles and submitting individual case data using MeasureSMS, after which they undertook a LF morbidity survey. After the reporting period, a random sample of reported cases was visited by a physician to verify the health workers’ diagnoses. The proportion of correctly diagnosed cases i.e. the positive predictive value (PPV) was then calculated. Results HSAs in Malawi successfully reported 256 unique cases by SMS from 107 communities (166 hydrocoele, 88 lymphoedema, 2 with both), resulting in an estimated adult prevalence of 17.7 per 10,000 and 33.0 per 10,000 for lymphoedema and hydrocoele respectively. In Ghana, despite being less experienced in using SMS, CHWs successfully reported 360 unique cases by SMS from 33 communities (169 hydrocoele, 185 lymphoedema, 6 with both), resulting in an estimated adult prevalence of 76.9 per 10,000 and 70.5 per 10,000 adults for lymphoedema and hydrocoele respectively. The verification exercise resulted in a PPV for lymphoedema and hydrocoele diagnosis of 90 % (n = 42, 95 % CI 76.5 – 96.9) and 92 % (n = 49, 95 % CI 79.5 – 97.4) in Malawi and 94 % (n = 34, 95 % CI 78.9 %–99.0 %) and 47 % (n = 59, 35.1 %–61.7 %) in Ghana, indicating that non-invasive methods for diagnosing hydrocoeles needed to be further emphasised. Conclusions The study concludes that given the appropriate education and tools, community-based health workers are exceptionally well-placed to participate in quantifying LF morbidity burden, and other NTDs with observable symptoms. This concept has the potential to enable national programmes to more effectively monitor their community impact in an efficient, timely and cost-effective way.

Abstract
The African Program for Onchocerciasis Control (APOC) was launched in 1995 with the main goal being to boost the fight against onchocerciasis in Africa. In 2011, over 80 million people benefited from this intervention thanks to the contribution of 268.718 Community-Directed Distributors (CDD). These significant results obscure the role of women CDD in this fight. Indeed, the insufficient involvement of female CDD has been identified as a concern by the APOC partners early in the program. The present study aims to assess the contribution and performance of women involved in a strategy to control onchocerciasis by community-directed treatment with ivermectin in sub Saharan Africa. We searched the following electronic databases from January 1995 to July 2013: Medline, Embase (Excerpta Medica Database), CINAHL (Cumulative Index to Nursing and Allied Health Literature), LILAS (Latin American and Caribbean Literature on Health Sciences), International Bibliography of Social Sciences, Social Services Abstracts, and Sociological Abstracts. Two research team members independently conducted data extraction from the final sample of articles by using a pre-established data extraction sheet. The primary outcome was the contribution of female CDD in the control of onchocerciasis by community-directed treatment with Ivermectin. Of 25 hits, 7 papers met the inclusion criteria. For the management of onchocerciasis, female CDDs are elected by the health committee from the communities they will serve. The significant proportion of those treated (about 61%) were women, although only 24% of CDDs were women. Many community members reported that women were more committed, persuasive and more patient than men in the distribution of ivermectin. Some studies have identified underutilization of female CDD as one reason for the limited effectiveness or, in some cases, pure failure related to the distribution of Ivermectin interventions in the fight against onchocerciasis in sub-Saharan Africa. Evidence from this review suggests that female CDD contribute to the treatment of onchocerciasis with Ivermectine in sub-Saharan Africa. Large-scale rigorous studies including Randomized controlled trials (RCTs) are needed to compare Community-Directed intervention involving men and women CDDs.

Abstract
Background Less is known about mass drug administration [MDA] for neglected tropical diseases [NTDs] than is suggested by those so vigorously promoting expansion of the approach. This paper fills an important gap: it draws upon local level research to examine the roll out of treatment for two NTDs, schistosomiasis and soil-transmitted helminths, in Uganda. Methods Ethnographic research was undertaken over a period of four years between 2005-2009 in north-west and south-east Uganda. In addition to participant observation, survey data recording self-reported take-up of drugs for schistosomiasis, soil-transmitted helminths and, where relevant, lymphatic filariasis and onchocerciasis was collected from a random sample of at least 10% of households at study locations. Data recording the take-up of drugs in Ministry of Health registers for NTDs were analysed in the light of these ethnographic and social survey data. Results The comparative analysis of the take-up of drugs among adults revealed that although most long term residents have been offered treatment at least once since 2004, the actual take up of drugs for schistosomiasis and soil-transmitted helminths varies considerably from one district to another and often also within districts. The specific reasons why MDA succeeds in some locations and falters in others relates to local dynamics. Issues such as population movement across borders, changing food supply, relations between drug distributors and targeted groups, rumours and conspiracy theories about the 'real' purpose of treatment, subjective experiences of side effects from treatment, alternative understandings of affliction, responses to social control measures and historical experiences of public health control measures, can all make a huge difference. The paper highlights the need to adapt MDA to local circumstances. It also points to specific generalisable issues, notably with respect to health education, drug distribution and more effective use of existing public health legislation. Conclusion While it has been an achievement to have offered free drugs to so many adults, current standard practices of monitoring, evaluation and delivery of MDA for NTDs are inconsistent and inadequate. Efforts to integrate programmes have exacerbated the difficulties. Improved assessment of what is really happening on the ground will be an essential step in achieving long-term overall reduction of the NTD burden for impoverished communities.

Abstract
In areas of Nigeria where onchocerciasis is endemic, community-directed distributors (CDD) distribute ivermectin annually, as part of the effort to control the disease. Unfortunately, it has been reported that at least 35% of the distributors who have been trained in Nigeria are unwilling to participate further as CDD. The selection and training of new CDD, to replace those unwilling to continue, leads to annual expense that the national onchocerciasis-programme is finding difficult to meet, given other programme priorities and the limited resources. If the reported levels of attrition are true, they seriously threaten the sustainability of community-directed treatment with ivermectin (CDTI) in Nigeria. In 2002, interviews were held with 101 people who had been trained as CDD, including those who had stopped serving their communities, from 12 communities in south-eastern Nigeria that had high rates of CDD attrition. The results showed that, although the overall reported CDD attrition was 40.6%, the actual rate was only 10.9%. The CDD who had ceased participating in the annual rounds of ivermectin blamed a lack of incentives (65.9%), the demands of other employment (14.6%), the long distances involved in the house-to-house distribution (12.2%) or marital duties (7.3%). Analysis of the data obtained from all the interviewed CDD showed that inadequate supplies of ivermectin (P<0.01), lack of supervision (P<0.05) and a lack of monetary incentives (P<0.001) led to significant increases in attrition. Conversely, CDD retention was significantly enhanced when the distributors were selected by their community members (P<0.001), supervised (P<0.001), supplied with adequate ivermectin tablets (P<0.05), involved in educating their community members (P<0.05), and/or involved in other health programmes (P<0.001). Although CDD who were involved in other health programmes were relatively unlikely to cease participating in the distributions, they were more likely to take longer than 14 days to complete ivermectin distribution than other CDD, who only distributed ivermectin. Data obtained in interviews with present and past CDD appear vital for informing, directing, protecting and enhancing the performance of CDTI programmes, in Nigeria and elsewhere.

Abstract
Community-directed treatment with ivermectin (CDTI), for the control of onchocerciasis, was launched in Uganda in 1997. In East Africa, as in other endemic areas, the refusal to take the drug reduces treatment coverage and therefore poses a serious threat to attempts to eliminate onchocerciasis as a disease of public-health importance. In early 2003, an attempt was therefore made to determine the factors associated with refusal to take ivermectin during mass treatment in 2002, by interviewing the individuals, from three Ugandan villages with CDTI, who had been eligible to receive ivermectin. The subject's socio-demographic characteristics, history of adverse reactions and participation in CDTI-related activities were explored, as potential 'risk' factors for refusing ivermectin in the treatment round in 2002. When odds ratios (OR) for refusal and their associated 95% confidence intervals (CI) were calculated, the villagers aged 18-35 years were found more likely to have received ivermectin in 2002 than their older counterparts (OR = 0.55; CI = 0.33-0.93). Individuals with an inter-current medical condition were also more likely to have received ivermectin in 2002 than the other villagers (OR = 0.56; CI = 0.32-0.99). Worryingly, the ingestion of ivermectin at any time before the 2002 treatment round was strongly associated with refusal to take ivermectin in that round (OR = 7.72; CI = 2.00-29.81), although there was no evidence that the adverse effects of treatment were significantly reducing coverage.

Abstract
The community-directed interventions (CDI) strategy achieved a desired coverage of the ultimate treatment goal (UTG) of at least 90% with ivermectin distribution for onchocerciasis control, and filled the gap between the health care services and the communities. However, it was not clear how its primary actors--the community-directed health workers (CDHW) and community-directed health supervisors (CDHS)--would perform if they were given more responsibilities for other health and development activities within their communities. A total of 429 of 636 (67.5%) of the CDHWs who were involved in other health and development activities performed better than those who were involved only in ivermectin distribution, with a drop-out rate of 2.3%. A total of 467 of 864 (54.1%) of CDHSs who were involved in other health and development activities also maintained the desired level of performance. They facilitated updating of household registers (P<0.05), trained and supervised CDHWs, and educated community members about onchocerciasis control (P<0.001). Their drop-out rate was 2.6%. The study showed that the majority of those who dropped out had not been selected by their community members. Therefore, CDI strategy promoted integration of health and development activities with a high potential for sustainability.

Abstract
Over a comparatively short period of time, the development and distribution of ivermectin (Mectizan) has radically altered the consequences of infection with Onchocerca volvulus. To achieve this required the fostering of many partnerships and the development of new tools and methods. The long-term commitment of Merck, the World Bank and other sponsors, as well as governments and non-governmental organizations, has been crucial. Yet the enthusiasm with which communities have taken up the delivery of ivermectin among themselves is perhaps the greatest reason for the success of this programme. The present challenge is sustaining the methods that have brought success so far, and making them part of health services and disease control programmes in some of the world's most impoverished and unstable areas. A major part of this challenge is continuing the commitment to controlling onchocerciasis as memory of the disease is fading, and while the hope of elimination or eradication for most endemic countries remains distant.

Abstract
This paper reviews the issues relating to compliance and participation among the men and women of three countries within the remit of the African Programme for the Control of Onchocerciasis (APOC): Cameroon, Nigeria and Tanzania. Project-monitoring data from 109 focus-group discussions, 6069 household-survey respondents and 89 interviews with ivermectin distributors were analysed to gain an insight into the attitudes and behaviours of men and women in relation to ivermectin treatment and their participation in the programme. Although there are no statistically significant gender differences in coverages for ivermectin treatment, culturally prescribed gender relationships influence the ways in which men and women express and experience treatment-related behaviours. Gender roles also affect participation in the programme. Decision-making in communities on the selection of distributors tends to follow socio-cultural hierarchies based upon patriarchy and gerontocracy. Relatively few ivermectin distributors (21%) are women. Although they receive less support than their male counterparts, the female distributors are just as willing to continue ivermectin distribution in the community, and they perform as well or better than men in this regard. The terms 'community-directed', 'community participation' and even 'compliance' obfuscate important gender differences that are inherent in the implementation of onchocerciasis control. Development of strategies that recognize these gender differences will have important implications for long-term adherence to treatment and for the overall quality and sustainability of the programme.

Abstract
Over the period 1997-2000, an evaluation was made, in 10 districts of Uganda, of the onchocerciasis-control programme based on community-directed treatment with ivermectin (CDTI). This programme is supported by the Ministry of Health, the African Progamme for Onchocerciasis Control (APOC) and The Carter Center Global 2000 River Blindness Programme. The data analysed came from: (1) monthly and annual reports; (2) annual interviews, in randomly-selected communities in selected districts, with heads of household, community leaders and ivermectin distributors; (3) participatory evaluation meetings (PEM); (4) participant observation studies; and (5) key informants. The percentage of treated communities in the 10 study districts achieving satisfactory treatment coverage [i.e. > or = 90% of the annual treatment objective (ATO)] rose from 46.0 in 1997 to 86.8 in 2000. This improvement was largely attributable to the adoption of collective CDTI decision-making by community members, avoidance of paving monetary incentives to the ivermectin distributors, and the satisfaction with the programme of those who had been treated. Coverage improved as the numbers of community members who were involved in choosing the method of distribution and in selecting their own community-directed health workers (CDHW) increased. Health education was also critical in improving individual members' involvement in decision-making, and in mobilizing other community members to take part in CDTI. Involvement of kinship groups, as well as educated community members as supervisors of CDHW, also helped to increase coverage. In a regression model, satisfaction with the programme was revealed as a significant predictor of the achievement of the target coverage (P<0.001). Cost per person, as an indicator for sustainability, varied with the size of the population under treatment, from at least U.S. $0.40 when the district ATO was <15,000 people, to U.S. $0.26 with an ATO of 15,000-40,000 and less than U.S. $0.10 when the district ATO exceeded 40,000 people. These results cast doubt on the validity of the current APOC indicator for sustainability, of a cost of no more than U.S. $0.20/person for all CDTI projects, whatever the size of the population to be treated. Although some women were involved in decision-making, their current involvement as supervisors or CDHW was minimal. Most of the present data were obtained through monitoring and operational-research activities that have been carried out, in an integrated fashion, within the Ugandan CDTI programme since its launch. It is recommended that assessment, monitoring and evaluation be widely used within all CDTI efforts. Operational research should remain focused and appropriate and directly involve the personnel who are executing the programme.
