Myanmar is one of the five countries with documented cases of emergence of artemisinin resistance. This project aims to develop a robust satellite data driven early warning system (Myanmar Malaria Early Warning System, MMEWS) that enables spatially-explicit monitoring and forecasting of potential surges in malaria burden in Myanmar. This approach quantifies malaria outbreak potential using an IPCC-defined risk-assessment framework which includes hazard, exposure, and vulnerability components. Data fusion from moderate (Landsat) and coarse (MODIS) resolution optical sensors supports the 8-day dynamic spatially explicit (resolved to village level) assessment of malaria burden potential. This project is developed by a team of experts in satellite remote sensing, geospatial modeling, and malariology and offers support for medical intervention and other decision-making activities in the Yangon office of the Institute for Global Health and regional partners and stakeholders. (December 2020 Update).
- The Malaria Burden Potential model runs in two modes – retrospective and forecasting – where differences are found in implementation of gap-filling methods for satellite observations.
- The full-scale model is assembled and executed retrospectively for five consecutive years (2016-2020) at the specified in the requirements spatial (240m country wide with localized zoom in at 30m) and temporal (8-day) resolutions (Figure 1).
- Model coding is optimized to enable in-country operations with locally available computing resources.
- The alternative web-based system delivery platform has been established, and the team has completed historic runs (2016-2020) and initiated porting data into the WebGIS platform.
