Perceived Risk of Dengue in Ones' Living Environment as a Determinant of Behavior Change through Social Mobilization and Communication: Evidence from a High Risk Area in Sri Lanka.

BACKGROUND: The aim of this study was to assess community knowledge and behavioral impact of the social mobilization and communication strategy applied in a dengue high-risk area in Sri Lanka. METHODS: A group of adults visiting selected primary care facilities in Colombo district were interviewed to collect socio-demographic data, attributes of knowledge regarding dengue and the responsive behaviors adopted by them following the dengue control program though the media and social marketing campaigns. These attributes were classified as 'good', 'fair,' or 'poor' by developing a composite scale for analysis and interpretation of data. RESULTS: The primary source of information was television in the majority. The overall knowledge of the disease, vector and control methods was poor. The overall level of contribution to dengue control activities was good. CONCLUSION: Awareness of the disease and its complications had not contributed to favorable behavior changes. While the social mobilization and behavior change campaign in Sri Lanka had low impact on knowledge and behaviors, a better understating of community perceptions of DF and how these perceptions are formulated within the social and cultural context; would be useful to improve uptake. This knowledge would be valuable for program planners to strengthen dengue control activities in SL and other similar settings across the region.

Malaria is an important differential diagnosis in visitors returning from Sri Lankan National Safari Parks.

Diagnostic confusion may occur between dengue and malaria when febrile patients with thrombocytopenia return from travel to previous malaria endemic areas. Laboratory tests should include blood smear examination for malaria parasites even though current malaria endemicity in Sri Lanka is low.
