Perceptions, attitudes and practices towards scabies in communities on the Bijagós Islands, Guinea-Bissau.

BACKGROUND: Scabies is highly endemic among impoverished populations and has been recently included in the WHO's list of neglected tropical diseases (NTDs). Community support and behavioural changes are essential for the success of control interventions. This study aimed to explore beliefs, prevention attitudes and healthcare-seeking behaviours towards scabies in the Bijagós Archipelago of Guinea-Bissau. METHODS: Data were collected through two methods. Community key informants (community members, community health workers, healthcare workers and traditional healers) were interviewed using snowball sampling. A questionnaire covering perceptions, attitudes and practices was administered to community members using random cluster sampling. Thematic analysis of qualitative data was applied to identify themes. Descriptive statistics were used for quantitative data analysis. RESULTS: There was a satisfactory awareness about scabies, but perceptions about disease causation and transmission were imprecise. Misconceptions about personal hygiene as the primary measure for scabies prevention were recurrent. Some participants recognised the importance of early treatment to interrupt transmission. Treatment of close contacts was not considered important. Costs were the main determining factor for treatment choice between traditional healer and the local health centre. Late presentation and delayed treatment were common and associated with poverty and stigmatisation. Scabies impaired quality of life by affecting social interactions, health, fitness to work and school attendance. CONCLUSIONS: There is a need to improve education, recognition, management and affordable access to treatment. Community education, healthcare workers' training and skin NTD integrated control programmes should address the challenges highlighted in this study.

The prevalence of scabies, pyoderma and other communicable dermatoses in the Bijagos Archipelago, Guinea-Bissau.

INTRODUCTION: Skin diseases represent a significant public health problem in most low and middle income settings. Nevertheless, there is a relative paucity of high-quality epidemiological data on the prevalence of these conditions. MATERIALS/METHODS: We conducted two cross-sectional population-based skin-surveys of children (6 months to 9 years old) in the Bijagós Archipelago of Guinea-Bissau during the dry season (February-March 2018) and the wet season (June-July 2018). Following a period of training, a nurse performed a standardised examination for communicable dermatoses for each participant. We calculated the prevalence of each skin condition and investigated demographic associations. RESULTS: 1062 children were enrolled in the dry season survey of whom 318 (29.9%) had at least one skin diseases. The most common diagnosis was tinea capitis (154/1062, 14.5% - 95% CI 12.5-16.8%) followed by tinea corporis (84/1062, 7.9% - 95% CI 6.4-9.7%), pyoderma (82/1062, 7.7% - 95% CI 6.2-9.5%) and scabies (56/1062. 5.2% - 95%CI 4.0-6.8%). 320 children were enrolled in the wet season survey of whom 121 (37.8%) had at least one skin problem. Tinea capitis remained the most common diagnosis (79/320, 24.7% - 95% CI 20.1-29.9%), followed by pyoderma (38/320, 11.9% - 95% CI 8.6-16.1%), tinea corporis (23/320, 7.2% - 95% 4.7-10.7%) and scabies (6/320, 1.9% - 95% CI 0.8-4.2%). CONCLUSIONS: Our study, which utilised robust population-based cluster random sampling methodology, demonstrates the substantial disease burden caused by common communicable dermatoses in this setting. Given these findings, there is a need to consider common dermatoses as part of Universal Health Coverage to deliver 'skin-health for all'.
