As we have seen the coronavirus spread across the world and affecting people, I feel powerless working from home on my day to day job as a backend engineer.

I wonder what application could help reduce the impact of the crisis.

I believe the South Korean and China have introduced some apps to mitigate the disease but that comes with some privacy concerns.

I wonder if an open source solution could be develop mitigating the privacy concern. I don't have any expertise with this but I'm thinking encryption / blockchain / federate ...

This app / servicer could then be used by countries with less technically advanced countries as the virus spread.

Does anyone know if such project exist or would be interest in starting something like that ?
