“…Such interventions require knowledge of existing vectors, particularly in terms of abundance. However, apart from a rapid entomological investigation in 2004 following a yellow fever outbreak in Bobo-Dioulasso [15], there have been no entomological studies conducted in Ouagadougou [16,17].…”

Background: Several studies highlighted the impact of community-based interventions whose purpose was to reduce the vectors' breeding sites. These strategies are particularly interesting in low-and-middle-income countries which may find it difficult to sustainably assume the cost of insecticide-based interventions. In this case study we determine the spatial distribution of a community-based intervention for dengue vector control using different entomological indices. The objective was to evaluate locally where the intervention was most effective, using spatial analysis methods that are too often neglected in impact assessments. Methods: Two neighbourhoods, Tampouy and Juvenat in Ouagadougou, Burkina Faso, were chosen among five after a survey was conducted, as part of an assessment related to the burden of dengue. As part of the communitybased intervention conducted in Tampouy between August and early October 2016, an entomological survey was implemented in two phases. The first phase consisted of a baseline entomological characterization of potential breeding sites in the neighbourhood of Tampouy as well as in Juvenat, the control area. This phase was conducted in October 2015 at the end of the rainy season. The mosquito breeding sites were screened in randomly selected houses: 206 in Tampouy and 203 in Juvenat. A second phase took place after the intervention, in October 2016. The mosquito breeding sites were investigated in the same yards as during the baseline phase. We performed several entomological analyses to measure site productivity as well as before and after analysis using multilevel linear regression. We used Local Indicators of Spatial Association (LISAs) to analyse spatial concentrations of larvae. Results: After the intervention, it is noted that LISAs at Tampouy reveal few aggregates of all types and the suppression of those existing before the intervention. The analysis therefore reveals that the intervention made it possible to reduce the number of concentration areas of high and low values of pupae. Conclusions: The contribution of spatial methods for assessing community-based intervention are relevant for monitoring at local levels as a complement to epidemiological analyses conducted within neighbourhoods. They are useful, therefore, not only for assessment but also for establishing interventions. This study shows that spatial analyses also have their place in population health intervention research.

“…Around doubtful cases of Bobo-Dioulasso, revival for a second Blood sampling from patients obviously missed coordination and means to lead a true multi-disciplinary investigation on epidemiologic, virological and entomological plan. Confirmed cases of 2010 come mainly from Western area of Burkina recognized as an area of strong yellow fever endemicity of where cases are regularly described [5,22]. This area is frontier with Ivory Cost in its Northern part where cases of yellow fever are often described [23,24]; and also with the West of Mali (Sikasso) where one has relatively little information.…”

Countries in Southern Africa such as Uganda [7], Democratic Republic of Congo also announced confirmed cases of Yellow fever [3].…”

This last decade, Burkina Faso has been confronted with yellow fever confirmed cases, mainly from Western part of the country. In 2010, National Reference laboratory of yellow fever received 970 sera of suspected cases from the 65 Health Districts of the country. We found 11 positive results by ELISA test researching specific IgM against yellow fever. An aliquot of these eleven positive sera were sent to Dakar for confirmation by sero neutralization and RT-PCR. Eight have been confirmed by regional laboratory of Pasteur Institute of Dakar and three were classified as doubtful. Confirmed cases were manly notified by Sindou (4/8) and Mangodara (3/8) Health Districts and the last one came from Nongr-masson health District situated in the central part of the country. Three out of the four confirmed cases in Sindou Health District were resident from neighboring village in Ivory Cost. Conformed cases coming from neighboring villages of Ivory Cost were difficult to manage because of the relative lack of coordination between the two health centers responsible in two different countries. The three cases were not notified to Ivory Cost Health authorities and, in addition, they didn't benefit from the Burkina Faso response plan. The goal of this work is to present results from National Reference yellow fever laboratory in 2010 in Burkina Faso and stressing trans-frontier cases management problems in order to suggest a multinational mechanism of response to fight against this disease more effectively.

“…Our study shows that 356 six-month- to six-year-old children were vaccinated (21.3%) among the 1673 children with a health record, indicating a limited coverage. Indeed, between 2000 and 2008, yellow fever cases have been identified in the southeast of Burkina Faso, but not in or around Ouagadougou [13]. Dengue fever cases have been reported in Ouagadougou since 2008 [8,45].…”

“…In 2013, dengue was reported in healthcare centers of Ouagadougou [9]. For yellow fever, the survey carried out by Yaro et al [13] in the Southwestern part of Burkina Faso showed an increase of confirmed cases between 2003 and 2005, possibly associated with the intensification of migration between Burkina Faso and Côte d’Ivoire.…”

Dengue is an emerging infectious disease of global significance. Although this virus has been reported for a long time, its significance within the burden of diseases in West Africa is not obvious, especially in Burkina Faso. Our objective was to evaluate flavivirus presence in Ouagadougou (Burkina Faso) and the link between anti-flavivirus antibody seroprevalence and urbanization modes. A population-based cross-sectional survey was conducted and 3015 children were enrolled from Ouagadougou districts with different types and degrees of urbanization (with/without equipment and high/low building density). Flavivirus (FLAV) IgM MAC-ELISA and FLAV indirect IgG ELISA were performed. Associations between FLAV IgG presence (sign of past infection) and various independent variables were assessed using the chi-square test and a multivariate logistic regression analysis. The apparent prevalence of past flavivirus infections among the enrolled children was 22.7% (95% CI: 22.4–26.7) (n = 685). Eleven children (0.4%; 95% CI: 0.61–2.14) were positive for FLAV IgM, indicating active transmission. Factors associated with flavivirus infection were identified among the enrolled children (age, sex), householders (educational level, asset index) and in the environment (building density, water access, waste management and house appearance); however, they showed great variability according to the city districts. The water access modality did not significantly influence FLAV IgG positivity. Conversely, apparently good practices of waste management had unexpected consequences (increased risk related to municipal dumpsters). Given the scale of ongoing urbanization and the spread of arboviral diseases, close collaboration between health and city stakeholders is needed.
