The Indiana University Fairbanks School of Public Health has been doing an ongoing study of the prevalence of covid-19 in the state of Indiana. Their latest numbers really surprised me. As of November 20, they estimate that only 10.6% of the state has been infected. The reason this surprised me is that it would mean about 715,000 people have been infected, and we had about 280,000 confirmed cases on 11/20. So, it would seem to imply that since the start of the pandemic, testing in Indiana has successfully caught about 1 out of 2.5 cases (I understand the lag with testing and getting results, but just keeping it simple). That goes against basically everything I have read. I acknowledge that there is state by state variance on how many cases have been caught, but 1 out of 2.5 sounds like an awfully damn good success rate. I was wondering if I'm missing something and there's some word gaming, like does a confirmed case not always equal an infection, but I don't know.
If the 10.6% is somehow right, and I have my doubts, it's bad news as the state has already had well over 5k deaths and vaccines are still weeks to months away.
