@AstorAaron It's hard to know. Our positivity rate actually been pretty similar than the US as a whole! Wild guess is that we're ascertaining 2x better than the rest of the US, so catching about 1 in 5 cases. So maybe ~50% attack rate by the time the wave is over but probably not yet. — PolitiTweet.org
