The study areas consist of 20 distinct clusters which create geographic boundaries that enable researchers to study them without interference from other study areas. The study included 20 clusters which consisted of 10 clusters from Kheybar Health Center and 10 clusters from Qods Health Center. The study used random allocation to assign clusters to the two study arms at a 1:1 ratio between intervention and control groups. The research study will invite all eligible households from the chosen clusters to participate in the research study, Blinding description: Clusters will be randomly assigned to either the intervention arm or the usual care arm using a computer-generated random sequence. An independent statistician who has no role in participant recruitment and intervention delivery will perform the randomization process. Allocation concealment will be ensured at the cluster level. The allocation sequence will be kept in sealed, opaque envelopes and will not be disclosed until clusters have been enrolled. N/A Educational intervention using risk communication and social motivation framework to prevent the spread and spread of invasive Aedes mosquitoes. Intervention 1: Intervention group: The intervention will establish a community-based program which depends on the Risk Communication and Community Engagement (RCCE) framework as its foundational element. The program will run for 2 months and it will include these program components: 1.Risk communication: Delivery of culturally tailored messages addressing Aedes mosquito risks, dengue and other Aedes-borne diseases, modes of transmission, symptoms, and prevention strategies. 2.Community engagement: The community leaders together with health volunteers and local organizations will actively work to create a situation where people will join together to share accountability. 3.Behavioral motivation: The manual offers people practical steps which will help them remove mosquito breeding areas that include stagnant water near their homes while teaching them how to continue their preventive practices. 4.Communication channels: The program will use household visits and group sessions together with printed educational materials and digital and social media platforms which are suitable for the local community. The program will provide all activities through trained community health workers CHWs and primary health care staff who will implement activities according to standardized manuals and supervision protocols. Intervention 2: Control group: The usual care group will receive ongoing standard vector control and health education services which the local health system provides. The health centers use passive information delivery to their customers together with standard environmental health methods which do not include community engagement and do not use RCCE framework for their environmental health work. No - There is not a plan to make this available Justification or reason for not sharing IPD is Despite of anonymity of the obtained consent from participants, we assured them that their personal information would not be made public.
