Some say the US is doing better fighting the #coronavirus . Yes and no. Thread.
This chart shows NEW DAILY cases in the US states, stacked. Very much up and to the right. We& #39;re adding now 35k cases/day. That& #39;s half an official Hubei. [1/9]

Good news: 18 states have a decreasing or stable # of new daily cases. You can see them in the chart: they& #39;re all the bottom ones up to the grey one (CA).
Bad news: 32 are still accelerating their # of daily cases [2/9]
Bad news: 32 are still accelerating their # of daily cases [2/9]
So are we good or bad? Let& #39;s look at Chart 2.
Horizontal axis: daily growth in new cases. 50% means today you had 100 new cases and tomorrow you& #39;ll have 150. It gives you a sense of how bad the situation is officially. [3/9]

Vertical axis: % tests that are positive. 3% means you& #39;re testing a lot of people, so you know well the situation. 40% means you have no idea, because you& #39;re not testing enough. So higher up means you don& #39;t really know what& #39;s happening in your state.

Let& #39;s take a few examples.
North Dakota has only 3% of positives. The # of new cases is down 10% every day. Fantastic. They see cases going down, and it probably reflects reality. Plus they have less than 200 cases total, so it might be a state with things under control. [5/9]

North Carolina grew over the last 3 days at 80% day over day in new cases. That& #39;s like multiplying by 60x in a week. Their testing is at 6% of positives, so maybe they& #39;re seeing all this growth just because they& #39;ve ramped up testing. In any case, doesn& #39;t look good. [6/9]
New York is still growing at 15% new cases day over day, and their testing is still 40% positives, so they& #39;re still undercounting. This is bad. [7/9]
Georgia and Mississippi are decreasing by ~10% every day. That sounds awesome! Except they have no idea because 24% of their tests are positive. So it might just be wishful thinking, luck, not enough testing, or bad testing. They don& #39;t know. [8/9]
