The Problem

Dengue fever is the fastest spreading mosquito-borne viral disease in the world today, prompting the World Health Organisation (WHO) to include the virus in the world’s top 10 public health threats. It costs the Health Services of low to middle-Income countries around $8 billion annually.

The Solution

D-MOSS, the Dengue MOdel forecasting Satellite-based System, is the first functional dengue fever early warning system that uses satellite Earth Observation (EO) data, in-situ observations, and seasonal climate forecasts to issue forecasts of dengue fever on a regular basis. The D-MOSS dengue fever early warning system produces accurate forecasts allowing Ministries of Health to take proactive action to reduce cases before outbreaks occur.

How it works?

  • Step 1: Working with Ministries of Health to introduce the D-MOSS dengue fever early warning system
  • Step 2: National stakeholders upload the latest dengue fever case numbers
  • Step 3: National and regional stakeholders receive forecasts of dengue fever outbreaks for their areas of responsibility.The forecast is driven by satellite data, seasonal meteorological forecasts and recently reported cases
  • Step 4: National stakeholders undertake national planning of resources 5-6 months in advance, using the forecasts to aid decision-making
  • Step 5: Regional stakeholders are guided by the forecasts in targeting the spraying of mosquito breeding sites 1-2 months in advance
  • Step 6: Regional stakeholders are guided by the forecasts in issuing community-level warnings to reduce standing water and take action to avoid mosquito bites 2 weeks to 2 months in advance

Bridging the digital divide

D-MOSS provides low to middle-income country stakeholders with a leading-edge digital tool to aid mosquito-borne disease control; the first of its kind in the world to be accessible through an internet browser.

Impact and highlights

  • Provided dengue fever forecasts for the entire population of Vietnam each month since June 2019.
  • Reduction in dengue fever incidence rates in 4 monitored Vietnamese provinces by an average of 8 cases per 100,000 people (up to a 20% reduction).
  • Provided dengue fever forecasts for the entire populations of Sri Lanka and Malaysia each month since June 2020.

Plans for expansion

Ongoing discussions to expand D-MOSS to Indian states, Singapore, Pakistan, The Caribbean, Central and South America, and Africa.
