BackgroundIn regions where access to clean water and the provision of a sanitary infrastructure has not been sustainable, cholera continues to pose an important public health burden. Although oral cholera vaccines (OCV) are effective means to complement classical cholera control efforts, still relatively little is known about their acceptability in targeted communities. Clarification of vaccine acceptability prior to the introduction of a new vaccine provides important information for future policy and planning.MethodsIn a cross-sectional study in Katanga province, Democratic Republic of Congo (DRC), local perceptions of cholera and anticipated acceptance of an OCV were investigated. A random sample of 360 unaffected adults from a rural town and a remote fishing island was interviewed in 2010. In-depth interviews with a purposive sample of key informants and focus-group discussions provided contextual information. Socio-cultural determinants of anticipated OCV acceptance were assessed with logistic regression.ResultsMost respondents perceived contaminated water (63%) and food (61%) as main causes of cholera. Vaccines (28%), health education (18%) and the provision of clean water (15%) were considered the most effective measures of cholera control. Anticipated vaccine acceptance reached 97% if an OCV would be provided for free. Cholera-specific knowledge of hygiene and self-help in form of praying for healing were positively associated with anticipated OCV acceptance if costs of USD 5 were assumed. Conversely, respondents who feared negative social implications of cholera were less likely to anticipate acceptance of OCVs. These fears were especially prominent among respondents who generated their income through fishing. With an increase of assumed costs to USD 10.5, fear of financial constraints was negatively associated with anticipated vaccine acceptance as well.ConclusionsResults suggest a high motivation to use an OCV as long as it seems affordable. The needs of socially marginalized groups such as fishermen may have to be explicitly addressed when preparing for a mass vaccination campaign.

Summaryobjectives To document peoples' perceptions of the benefits of taking ivermectin, as an important predictor of sustained compliance with long-term ivermectin treatment, and to identify the sociodemographic correlates of perceived benefits of ivermectin treatment.methods Multisite study in Cameroon, DRC, Nigeria and Uganda. A structured questionnaire was administered to 1600 persons randomly selected from household treatment records. Community leaders, community-directed drug distributors (CDDs) and health workers were interviewed using in-depth interview guides, while focus group discussions (FGDs) were held with community members to capture factors that reflected their perception of benefits of community-directed treatment with ivermectin (CDTI). Case histories of persons with special experiences with onchocerciasis were collected.results In this study, 84.7% of respondents indicated that ivermectin treatment has many benefits. The social benefits of CDTI included improved ability to work, peer acceptance and improved school attendance. Other individual benefits included self-respect ⁄ esteem, election to political office and improved relationship in the homes. The health benefits included improved skin texture and less ill health. Important demographic factors that influenced perception of the benefits of taking ivermectin, include marital status (P = 0.012), age (P = 0.029) and length of stay in onchocerciasis-endemic communities (P < 0.001). Another factor was individual perception of susceptibility to onchocerciasis infection (P < 0.0001).conclusion A programmatic focus on the benefits of CDTI could provide a basis for motivating communities to comply with long-term treatment with ivermectin. The results illustrate the importance of capturing beneficiaries' perceptions towards CDTI as a resource for producing health education materials for increasing the sustainability ivermectin distribution in endemic countries.

Forms of onchocerciasis-related stigmatisation, following over 10 years of implementation of community directed treatment with ivermectin (CDTI), were documented through a survey conducted between September and November 2009 to look at perceived changes in stigma over the past 7-10 years. We documented people's perceptions towards stigma before and after the introduction of CDTI from 1600 structured interviews with households selected from the community treatment registers; in-depth interviews with 57 community leaders, community directed distributors and health personnel; 33 focus group discussions with male and female community members in different age groups (18-24, 25-54 and ≥55 years) and 13 case studies. People with onchocercal skin disease (OSD) with rough skin, swellings and rashes were the most stigmatised. People still fear sexual intimacy with infected persons. In the past, people with OSD were considered unclean and stigmatised because of fear of OSD transmission and embarrassment. People who had lived in the community less than 5 years tended to stigmatise OSD patients more than those people who had lived in the community for longer than 5 years. The youth stigmatised the most. Although stigmatisation persists, avoidance of people with OSD decreased from 32.7% to 4.3%. It is notable that treatment availability has improved relationships between healthy people and those with OSD symptoms in endemic communities and this can be attributed to CDTI. Health education should be emphasised in the communities during distribution.

Abstract. Rotavirus and oral cholera vaccines have the potential to reduce diarrhea-related child mortality in low-income settings and are recommended by the World Health Organization. Uptake of vaccination depends on community support, and is based on local priorities. This study investigates local perceptions of acute watery diarrhea in childhood and anticipated vaccine acceptance in two sites in the Democratic Republic of Congo. In 2010, 360 randomly selected non-affected adults were interviewed by using a semi-structured questionnaire. Witchcraft and breastfeeding were perceived as potential cause of acute watery diarrhea by 51% and 48% of respondents. Despite misperceptions, anticipated vaccine acceptance at no cost was 99%. The strongest predictor of anticipated vaccine acceptance if costs were assumed was the educational level of the respondents. Results suggest that the introduction of vaccines is a local priority and local (mis)perceptions of illness do not compromise vaccine acceptability if the vaccine is affordable.

Although the depiction of a child leading a blind man is the most enduring image of onchocerciasis in Africa, research activities have hardly involved children. This paper aims at giving voice to children through drawings and their interpretation. The study was conducted in 2009 in Cameroon, Democratic Republic of Congo (DRC), Nigeria and Uganda. Children aged 6–16 years were asked to draw their perceptions of onchocerciasis and community-directed treatment with ivermectin (CDTI) in their communities. A total of 50 drawings were generated. The drawings depicted four main aspects of onchocerciasis: (1) the disease symptoms, (2) the negative consequences of onchocerciasis among children and in the community generally, (3) the ivermectin distribution process, and (4) the benefits or effects of taking ivermectin. Out of the 50 drawings, 30 were on symptoms, 7 on effects of the disease on children, 8 on distribution process, and 5 represented multiple perceptions on symptoms, drug distribution processes, benefits, and effects of treatment. The lack of clarity when treatment with ivermectin can be stopped in endemic areas requires working with children to ensure continued compliance with treatment into the future. Children's drawings should be incorporated into health education interventions.
