The document describes a web-based malaria disease surveillance and mapping project in northern Botswana. The project aimed to address slow reporting times and inefficiencies in the existing paper-based system by developing (1) smartphone forms for health workers to enter and submit data in real-time, and (2) a web-based tool for aggregating, analyzing, and mapping reported cases on an interactive map. The project helped reduce reporting times from 3-4 weeks to near real-time, and allowed health officials to more immediately investigate and respond to reported outbreaks.
