D-MOSS: Dengue forecasting MOdel Satellite-based System

Half the world’s population is now estimated to be at risk from the dengue fever, a mosquito-borne viral infection found in tropical and sub-tropical climates worldwide. We are leading the development of D-MOSS, a pioneering dengue forecasting system as part of a UK Space agency funded project. This system uses Earth Observation data to give early warning for dengue fever outbreaks in six South Asian countries.  

For the first time, an Earth Observation-based forecasting system allows decision makers to identify areas of high risk for disease epidemics before an outbreak occurs, in order to target resources so as to reduce an epidemic spreading and to increase disease control.

Darren Lumbroso, Technical Director

The D-MOSS early warning system is already live in Vietnam and is being implemented in Cambodia, Laos, Malaysia, Thailand, The Philippines and Sri Lanka. It gives beneficiaries several months advance warning of likely outbreaks of dengue fever. It allows local communities to mobilise to eliminate mosquito‑breeding sites thus reducing incidents of dengue. In combination with better outbreak response, we expect it will help reduce dengue incidence over the project lifetime.
