Some back-of-envelope math from #Indiana randomized #COVID19 sampling results:
- 2.8.% prevalence w/pop. ~6.73 million means ~188.5k infected
- Testing has found ~25k infected
- So, testing is finding ~13% of all infected
- For every case we find we are missing 6-7 other cases

Nice NYTimes article about the #Indiana random sampling project: https://www.nytimes.com/2020/05/13/opinion/indiana-reopening-coronavirus-testing.html
