Regarding to the effectiveness of controlling Aedes larvae in households after the campaign, BI decreased 28.9%, HI decreased 37% and CI decreased 28%. The risk containner before the campaign were water containers (59%) and after the campaign waste items (44%). The percentage of households had used the protection containners after the campaign is too low: 22.5% cover containners tightly, 7.6% fish.
