Influence of Socio-Spatial Determinants on Knowledge, Attitudes and Practices Related to the Plague in Populations Living in Endemic Areas in the Central Highlands of Madagascar
Résumé
Background: Plague is endemic to the central highlands of Madagascar. Sporadic human cases or outbreaks can occur annually in these areas. In Madagascar, the association between endemicity and the knowledge, attitudes and practices (KAP) of populations with regard to this disease remain poorly documented. The aim of this study was to assess KAP related to the plague of populations living in the central highlands. Methods: A cross sectional survey was conducted among the general population from June to August 2017. Based on the reported cases of plague between 2006 and 2015 in two central highland districts, a KAP questionnaire was administered to the population. Based on the proportion of correct answers provided by respondents, KAP scores were classified into three KAP categories: low (< Mean - SD), average (Mean ± SD) and good (> Mean + SD). Multivariate analyses were performed to determine the associations between population KAP scores related to plague with socio-demographic and epidemiological factors. In addition, individual interviews and focus groups with health professionals were conducted to assess plague perception. Results: A total of 597 individuals participated in the survey. Around 20% (n=119) had a good KAP score, 62% (n=370) an average KAP score and 18% (n=108) a low KAP score. Among the 119 respondents with a good KAP score, 80% (n=95) of them resided in Ambositra district and 20% (n=24) resided in Tsiroanomandidy district. According to the health professionals in the two districts, populations in endemic areas are well aware of the plague. A significant association with a lower KAP score was found in populations without mobile phone, having no contact with a former plague case and living in Tsiroanomandidy district (p<0.05). Conclusion: The results of the study showed the need to adapt plague control interventions to the local context to allow a better allocation of human and financial resources. This will minimize delays in patient management care and increase community resilience to plague epidemics.
