A Call-to-Action

The World Malaria Report 2020 has identified insecticide resistance (IR) in malaria mosquitoes as a biological threat that could derail efforts towards malaria control and elimination.

Our Solution

IR Mapper is a joint initiative of Vestergaard, KEMRI-CGHR and ESRI Eastern Africa to provide up-to-date insecticide resistance data and guide the deployment of vector control tools.

IR Mapper

Data science against malaria

Resistance monitoring is key in efforts to mitigate the effects of insecticide resistance in malaria endemic countries. Since 2012, IR Mapper has committed to consolidating and visualising data on insecticide resistance from peer reviewed published literature, with monthly updates. Data are centralised onto user-friendly, filterable maps to aid in informing the deployment of the most effective insecticidal tools in target geographical areas.

Unique & responsive

In 2020, IR Mapper partnered with the Geospatial Modelling of Insect Vectors group (GMIV), within the Big Data Institute at the University of Oxford, to address gaps in data in Sub-Saharan Africa. IR Mapper was able to use their maps that predict localised variation in insecticide resistance and the probability that malaria vector populations will exceed resistance thresholds to fill its own gaps relating to monitoring activities.
