Abstract

Dengue is becoming an endemic disease in Eastern Sudan with repeated outbreaks during last two decades. This study aimed to investigate an effective method for community participation in dengue vector control (Aedesaegypti) in Kassala city. The study was conducted during May to December 2011. A cluster was composed in eight neighborhood; each cluster was formed of three grouped houses.  One of these grouped houses was allocated randomly into one of three study arms: arm1 intervention of community volunteers; arm 2: intervention of house holder education and arm 3: Control. In arm 1, sixteen volunteers (two per cluster) inspected the water containers of houses weekly. In the house hold arm 2, householders received two educational sessions for breeding site of vectors source elimination and management of their water containers. In the control arm, houses did not receive any interventions. Bimonthly Entomological survey was conducted for eight months in each cluster of the study. The covering situation of inspected water containers was also recorded. From 9537 inspected containers, 545(5.71%) containers were found positive for aquatic stages of Aedes. aegypti. Zieers (localwater containers) composed 436 (80%) from the positive containers. ANOVA analyses were done between the three arms and no significant differences were found. Those entomological indices declined in community volunteers and householders arms. Also, the percentage of covering Zieers increased from 14.1% to 64.7% in community volunteer’s arm and from 12.1% to 32.6% in house holder arm. In control arm there was a fluctuation in all parameters. The arm of Community volunteers may be more effective in increasing the awareness of covering containers and decline of the entomological indices. Thus, it may be used as an approach for community participation in Dengue vector control in Kassala city.
