| This study was descriptive and analytical research which aimed to 1) to study the model of dengue haemorrhagic fever control that has the lowest expense 2) to study the prevention and the risk of dengue haemorrhagic fever of each control model 3) to demonstrate the appropriate time for dengue haemorrhagic fever prevention 4) to establish the correlation between the knowledge and the result of dengue haemorrhagic fever prevention 5) to study the equation to forecast the risk of dengue haemorrhagic fever of each control model. Data was collected between March to September 2005 from eight villages of Kantaraluk district, in which four villages were dengue-free and other four villages were dengue-exposed in 2004. Control models for dengue haemorrhagic fever prevention in this study were 1) fogging once a month 2) larviciding once a month 3) fogging and larviciding once a month 4) fogging and larviciding before and during infectious season. Each of control models was applied to two villages= a dengue-free village and a dengue-exposed village. Breteau index (BI) was collected every month in order to evalaute the risk of dengue haemorrhagic fever attraction. The knowledge of dengue haemorrhagic fever was evaluated using questionnaire.
The result showed that the average expenses for dengue haemorrhagic fever prevention per household each time in control models 1, 2, 3, and 4 were 21.38, 16.45, 36.52, and 19.02 Baht, respectively. |
