Intervention(s)
|
Feedback of for dengue immunological status and entomological indicators informs community-led pesticide-free interventions (for example, cleaning and sealing water tanks). Gender stratified focus groups and then community meetings will discuss possible interventions, based on this evidence. A small community action research team (CART) in Mexico and local brigadistas in Nicaragua (three to five people in each community) will receive training in pesticide free vector control and provide the continuity from season to season.
The duration is two dengue seasons - two years.
|
|
Primary Outcome(s)
|
Measured after the first dengue season (year 2) and in the third year, at the end of this phase of the trial:
1. Childhood recent dengue infection (age 4 - 9 years) as estimated by saliva IgG (two samples with 4-fold increase in titre)
2. Entomological index (pupal density)
|
|
Secondary Outcome(s)
|
Measured after the first dengue season (year 2) and in the third year, at the end of this phase of the trial:
"CASCADA" of intermediate outcomes:
1. Conscious knowledge regarding dengue, its prevention and control
2. Attitudes (in relation to different options for dengue control; is it worth doing this or that action)
3. Subjective norms (what neighbours do) and positive deviations from a negative norm
4. Intention to change behaviour in the future and to implement preventive action
5. Agency (collective and individual self-efficacy - feel capable of carrying out the actions in a sustained manner and with one's own resources)
6. Socialisation (discussions about dengue, its prevention, control and consequences)
7. Action (interventions, practices)
8. Health literacy, resilience, social capital
