I am wondering why don't people create a database where COVID-19 patients themselves can upload their data to help finding the answers. The dimensions I am thinking about is beyond basic "severeness" and "time to recover" but also nutrition/supplement informations or health condition informations, fitness, being too exhausted for a longer time / lack of sleep before sympthoms arise.

I know many of this is personal information and I also know it is hard to verify these pieces of information, but I think there are many people who are willing to help with their data, but there is no platform for that.

I don't know how to do this this is just the idea.

Edit: South Korea has already tested more than 140.000 people, (https://www.google.hu/amp/s/www.businessinsider.com/south-korea-coronavirus-testing-death-rate-2020-3%3famp ) it would be really interesting to see their data.
