Large-scale Data Collection Made Easy

IASO has become a trusted name for health data management with implementations in 12 countries and two large-scale multi-country projects, in support to the Global Polio Eradication Initiative and UN nutrition programs.

Effortless Geo Data Management
Oversee, refresh, and authenticate diverse organizational units – such as regions, districts, and health facilities, Master Lists and manage several geo data sources
Structured Data Collection Simplified
Build your Excel data collection forms (ODK format) and connect them to specific organization unit types (Region, District, Health Facility, etc.) for precise data organization and error prevention
DHIS2 Data Integration
Import or export your data from DHIS2, and continuously enrich DHIS2-based health programs with data collected via IASO
Microplanning and Campaign Digitization
On the field, the IASO mobile application will lead end-users to their pre-assigned data collection points or zones, even when data collection activities take place offline
Analyse and Visualize with Ease
Export your data or plug third-party BI tools (such as Power BI, Tableau, Superset) to create impactful visualizations decision-makers can rely on
Digital Public Good
IASO is recognized as a Digital Public Good by the Digital Public Good Alliance and listed as a Digital Square Software Global Good, a testament to its proven impact

Meet Raoul Nembot Mekoueng

Cameroon EPI Data Manager


“As an EPI (Expanded Program on Immunization) Data Manager, my responsibility is to make sure that vaccination campaigns in the field run to plan, even in situations with limited time and resources assigned.

Vaccinators sometimes have to go to very remote areas, so everything needs to be thought through in advance, as they will not always have access to internet or mobile data connection. 

For this, geo-enabled microplanning is key – it needs to be crystal clear for each team and field agent who should go where, how many children are required to be vaccinated, and the equipment available in order to be prepared to precision before heading to the field. Every detail counts as even the smallest error can lead to wasted time and resources.

Once in the field, the EPI data managers want to hear from the front-line colleagues and collaborators to identify issues or gaps in the system, and assist wherever needed.

That is why IASO was selected as the best-fit solution for Cameroon July 2023 measles vaccination campaign. To kick things off, we updated the Cameroon georegistry via IASO web and mobile App with all of the key information needed: target population, on-site equipment available, etc. The coverage for that campaign reached 93%, with 4.9 million children vaccinated by 9,000 teams on the field and 900 IASO end users.

With a freshly updated georegistry in place, the EPI could generate digital maps that in turn replaced our hand-drawn and non-validated sketched versions. All information was then available in a central repository. The data entered was done so for each team and for each locality, which now allows us to measure the vaccination and geographical coverage of each community and to be sure that no child has been left behind.

As an EPI data manager, I could monitor progress of the vaccination campaign across different dashboards to directly spot issues by drilling down into data loopholes. Once identified, I could then pick up my phone and call directly the assigned field agent for support – a big win for the optimization of the feedback loop and solution design. 


This use case is now being replicated to other vaccination campaigns.”
