Antenatal care as a platform for malaria surveillance: Utilizing community prevalence measures from the New Nets Project to validate ANC surveillance of malaria
The study aims to leverage the planned cross-sectional surveys and strengthened routine data conducted by the New Nets Project in each country to assess (1) whether the malaria infection prevalence data collected during ANC surveillance correlates with these estimates of community infection prevalence in children 6 to 59 months and (2) if intervention coverage data (particularly ITN ownership and use) collected from ANC surveillance are valid and representative of the population as a whole.
These additional data could catalyze a new model of surveillance for malaria, and greatly simplify evaluation of the impact of new interventions, as ANC surveillance could potentially replace or supplement cross-sectional household surveys, and provide more granular and timely data.
The specific objectives of this ANC surveillance pilot are to:
- Determine the prevalence of malaria infection and coverage of malaria control interventions among pregnant women attending their first ANC visit.
- Assess correlations between ANC surveillance parasite prevalence from this study, parasite prevalence collected by the New Nets Project during cross-sectional household surveys, and malaria incidence measured from health facilities.
- Analyze the correlation between health seeking and net use/access in the ANC surveillance and health seeking behavior compared to the cross-sectional survey responses.
