Upload landscapes, reports, grey literature, white literature, or other resources describing any digital tools that have been deployed at scale to capture health data. We are particularly interested in tools that have already been deployed across multiple facilities, districts, regions, or nationally within a country, rather than pilots of tools with a limited reach. Tools that could rapidly be adapted and deployed for COVID-19 are also of particular interest. Documents from the past 5 years (inclusive of 2015) are the priority, but anything from the past 10 years (inclusive of 2010) that includes systems that are still being deployed are also within scope.
