Can hidden malaria reservoirs be unmasked?
NCT ID NCT07770048
First seen Aug 18, 2026 · Last updated Aug 19, 2026 · Updated 1 time
Summary
This study in Odisha, India, aims to understand why malaria transmission persists in some areas despite control efforts. Researchers will follow about 3,000 residents to measure hidden infections that don't cause symptoms and may be missed by standard tests. They will also look for new biomarkers to improve detection and study mosquitoes around homes to see how transmission continues.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- This research could lead to better tools for detecting hidden malaria infections and strategies to interrupt transmission in regions where malaria persists despite control efforts.
- What could go wrong
- As an observational study, it won't test a new treatment or intervention. Findings may be specific to this region and may not directly translate to other settings.

Who is studied
Community residents living in selected rural villages in three districts of Odisha, India (Keonjhar, Boudh, and Malkangiri), representing different malaria transmission settings. Participants include males and females aged 12 months to 69 years who are enrolled through household-based community surveys and followed longitudinally to assess malaria infection, transmission dynamics, and biomarkers of infection. There are no restrictions based on residency duration, pregnancy status, social class, or underlying health conditions. For participants with severe anemia, study procedures are limited to finger-prick blood sampling in accordance with the study protocol.
