Detailed Description

Rapid diagnostic testing has been shown to be an important tool in controlling the spread of the COVID-19 pandemic by identifying people when they are likely to be most contagious and reducing crowding at testing sites. In addition to employer-mandated testing, rapid antigen tests are becoming increasingly used by individuals. A method to promote frequent self-testing would help break the chain of viral transmission, slow the spread of disease, slow the spread of vaccine-resistant variants, and improve pandemic management. The ubiquity of smartphones along with their data connectivity capabilities and onboard sensors make them an attractive tool to complement rapid diagnostic tests and an important component of decentralized testing. Smartphone-based tools have shown high acceptability among healthcare workers for the real-time tracking of rapid test results.
