Dengue in Trinidad: a survey of knowledge, attitudes, practices and beliefs in two communities in Trinidad, West Indies

ABSTRACT

This study was conducted to test the Health Belief Model as it relates to dengue fever in two urban communities, namely Curepe and Woodbrook, Trinidad using a knowledge, attitude, practices and beliefs questionnaire and entomological investigations. The knowledge of dengue symptomatology, its prevention and control suggested a high level of awareness about dengue and its aetiological agents among residents of both commuities, but the connection between the vector Aedes aegypti (L.) and dengue fever transmission was poorly understood. The major determinants for cues to action were demographics, prevention of water treatment and garbage collection and disposal. Data from the present study gave clear indications of the need for health education programs, defining what garbage is and the further studies using the transtheoretical model of change (Prochaska Model). With these tools a holistic approach to vector control using community participation, health education and conventional vector control strategies may be adopted for the prevention and control of dengue and its vector.
