Efficacy
The study has four research domains: epidemiology, entomology, social aspects, and cost-effectiveness.
For the epidemiology domain, the primary objective is to determine the protective efficacy of OlysetPlus ceiling net in reducing malaria clinical incidence in children 6 months to 14 years old over 18 months post-intervention.
For the entomology domain, the primary objective is to evaluate the impact of OlysetPlus ceiling nets on the mosquito density of the primary malaria vector species.
For the social science domain, the primary objective is to assess the determinants of social acceptability of the OlysetPlus ceiling net in both the intervention and control arms.
For the cost-effectiveness domain, the primary objective is to determine the incremental cost-effectiveness ratios (ICERs) of adding the OlysetPlus ceiling net to existing malaria control interventions under field trial conditions.
For the epidemiology domain, 1) to determine the protective efficacy of OlysetPlus ceiling nets in reducing Plasmodium infection prevalence by PCR in all age groups at 6-, 12-, and 18- months post-intervention; (2) to determine the protective efficacy of OlysetPlus ceiling nets against the time-to-first Plasmodium infection; (3) to determine the spillover effects of OlysetPlus ceiling nets in reducing Plasmodium infection prevalence in all age groups at 6-, 12-, and 18-months post-intervention; and (4) to determine the protective efficacy of OlysetPlus ceiling net in reducing Plasmodium infection incidence in children 6 months to 14 years old over 18 months post-intervention.
For the entomology domain, (1) to determine the impact of OlysetPlus ceiling nets on entomological inoculation rate (EIR) and (2) to determine the prevalence of knockdown resistance (kdr) mutations in vectors.
For the social science domain, (1) to determine the feasibility of installing the OlysetPlus ceiling and (2) to determine the appropriateness of fit of the OlysetPlus ceiling net in the context of households in Ndhiwa Sub-County.
For the cost-effectiveness domain, (1) to establish the relative contribution to costs of the distinct programmatic elements and identify the inputs that contribute the most to overall costs, and (2) to estimate the potential cost of providing OlysetPlus ceiling net at a larger scale over 3 and 5 years under operational scenarios.
