I already have a prototype, i just need to improve it.
The Open Coronavirus project offers, for this time interval, a digital solution for monitoring, diagnosing and containing SARS-CoV-2 infection that allows quarantine measures to be applied in a controlled manner at focal points or hotspots, thus minimizing the general quarantine of the population, reducing the overload of health systems, and at the same time facilitating the progressive resumption of daily activity in the shortest possible time.
The system will have 3 applications:
Citizen App. Collaborative Mobile app to control spread of SARS-CoV-2.
The application allows you to request a test, and receive the ensuing results. Will be made possible by a personalised QR code to identify the user.
Anonymous cross paths of the user (with Bluetooth Low Energy) will be logged into his mobile to control possible infections and to enable SARS-CoV-2 monitoring by health authorities.
The app uses Bluetooth Low Energy technology which is able to track possible COVID-19 exposure. Every citizen has the application installed and with bluetooth connected.
This is how the Bluetooth LE system works:
When two citizens are physically close their phones will exchange anonymous identification codes through Bluetooth LE. Each of these encounters will be stored in the phone's memory.
The proximity of the the two phones is measured based on the intensity of the bluetooth signal. It will also store the amount of time that you were with the individual who is COVID-19 positive to know your level of exposure to the virus.
This information will only be stored for a limited period of time as a protection to citizens' privacy. You can figure the amount of time using the tool but it is recommended to be set to between 14 and 37 days which is the amount of time in which a diagnosed carrier would have been able to infect others with COVID-19.
In the case that a citizen is tested positive for COVID-19, the application would update your QR status to red and perform the analysis to determine which people you could have been in close proximity to.
The system will upload to a server all potentially contagious encounters and would send a push notification to those individuals so that they would be aware of the potential risk and/or to encourage them to have a diagnostic test.
Centralised Data Management Software where health & epidemiologic control authorities will track the spread of SARS-CoV-2.
