Use of a portable field-adapted liquid chromatographic system (C-Vue machine) to estimate the quantity of deltamethrin on insecticide-treated nets paired with WHO cone bioassays to determine ITN bioefficacy as part of three-year durability monitoring in Mali.

Background: Monitoring insecticide levels and physical integrity over time is essential for assessing the durability of insecticide-treated nets (ITNs), which largely depends on the net handling habits of users. This study determined the insecticide content and effectiveness of ITNs (Yorkool and PermaNet 2.0) at 6, 12, 24, and 36 months after a mass distribution campaign in Mali.

Acceptability of innovative department community-based health insurance in central Mali: A mixed methods study.

As the Universal Health Insurance Plan (RAMU) is gradually being implemented in Mali, community-based health insurance (CBHI) -considered one of the pillars of this programme- must innovate to meet the challenge of universal health coverage. An experimental CBHI was tested in central Mali between 2017 and 2021. This innovative CBHI professionalizes and organizes risk sharing on a larger scale than before, moving from municipalities to circles (departments).
