I've been using this Live Science web page which appears to be fairly regularly updated and sources States data and news reports: https://www.livescience.com/coronavirus-updates-united-states.html https://www.livescience.com/coronavirus-updates-united-state... It's been pretty much on the ball. I've been maintaining a spreadsheet with States-level department of health Covid-19 situation page data and the totals roughly tally. As of 13:00 GMT March 12: 1,300+ positive cases, 38 deaths. You could multiply the positive number by factor of 10 say to get a rough estimate of the total number of persons tested to this point (~13,000 let's say) that individual states, private labs, and the CDC have checked. (Hard to say though as only about 1/3 to 1/2 of states release full data and some are under-reporting (Nebraska and Texas afaict)) Another niggle is that it can (does?) take more than one "test" to perform a test.
