The COVID-19 pandemic has accelerated the adoption of many innovations, including digital solutions to support access to diagnostics. These digital tools can be used by countries to expand support community-based testing and lessen the need to travel distances to clinical settings by moving testing meet patients where they are. 

This operational research study examines the utility of rapid diagnostics tests (RDTs) for COVID-19 detection in combination with an end-to-end digital health solution.This study took place between June and September 2021 at three local taxi ranks  in Johannesburg, South Africa. Over 15,000 members of the public were screened for COVID-19 risk factors via a digital questionnaire. Overall, the usage of the digital tool combined with RDTs were shown to improve decentralized service delivery, results reporting, and follow-up of COVID-19 testing at the community level.
