The Problem

Reveal aims to solve the outreach problem of health campaigns be it for malaria, vaccine-preventable diseases, or neglected diseases which have consistently low-population coverage. Reveal's data shows that more than 40% of households are routinely missed.

The Solution

Reveal provides end-to-end health campaign planning and delivery by putting the power of maps and spatial intelligence in the hands of community health workers to provide last-mile healthcare.

How it works?

  • Step 1: Configuration. Consolidating map layers (satellite imagery, household footprints, administrative hierarchies, point files, health catchments) and importing them to the Reveal system. Field team members are added to the system.
  • Step 2: Microplanning. Government stakeholders interact with the Reveal planning user interface (UI) to select organizational units to receive the campaign. Populations protected and commodities (e.g. number of vaccinations) required are calculated automatically.
  • Step 3: Once the micro plan is approved in the system, teams are automatically "tasked" through the Reveal mobile client. Using the mobile application, the user (community health worker or similar) goes to houses, villages, and points of interest within their intervention area, seeing their location in relation to each geographic entity.
  • Step 4: Once arrived at a target location (within X meters, configurable), the user can select the house.
  • Step 5: Data about household and family members is recorded, as well as the type of intervention delivered.
  • Step 6: Campaign progress (and coverage against population) and data are visualized on the mobile and web map.

Bridging the digital divide

The mobile application can operate offline and in areas of limited connectivity. Training materials including short video tutorials provide digitally illiterate individuals with basic training on how to operate the system. A helpdesk is available to support end users at both basic and also more advanced levels.

Impact and highlights

  • Increased malaria intervention coverage by 30% and decreased malaria incidence by 15% more (Zambia).
  • Reduced cost per malaria case averted by 63% (from $118 down to $44) in target areas of Zambia.
  • For every dollar spent, the use of Reveal has prevented nearly three times the number of cases compared to standard intervention.

Plans for expansion

Planning to expand to a total of 15 countries over the next 1-2 years.
