Alaska COVID-19 Count Friday April 17, 2020 - 9 More Cases

As I look at today's numbers, what stands out is that the state reports over 700 more tests yesterday.
So nine new cases is just over 1% positive of those tested.  This Atlantic article says the US has, overall, a 20% "test positivity rate."  Here's an short excerpt:

According to the Tracking Project’s figures, nearly one in five people who get tested for the coronavirus in the United States is found to have it. In other words, the country has what is called a “test-positivity rate” of nearly 20 percent.

That is “very high,” Jason Andrews, an infectious-disease professor at Stanford, told us. Such a high test-positivity rate almost certainly means that the U.S. is not testing everyone who has been infected with the pathogen, because it implies that doctors are testing only people with a very high probability of having the infection. People with milder symptoms, to say nothing of those with none at all, are going undercounted. Countries that test broadly should encounter far more people who are not infected than people who are, so their test-positivity rate should be lower.  

Now, that 1% was just based on the number of tests and number of new cases reported yesterday.  Those numbers don't necessarily get reported on the days the actually happened, so that doesn't really mean much.  If we take our total number of positives - 309 - and divide by the number of tests - 9450 - we get 3.2%, which is still comfortably low.  The article says South Korea has a 2% test positivity rate, because they have tested so many people.  Australia and New Zealand are also at 2% according to the article.

So far then, we're doing pretty well.

State Charts

Above is a screenshot.  You can enlarge and focus it by clicking on it, but you have to go to the actual interactive chart below if you want to play with it.  You need to scroll right to see it all, but don't forget to scroll back to see the rest of the post.

Yesterday, with my technical difficulties, I forgot to mention that they've added a new category of tests.  They've had State Labs, Private Labs, and now they've added Hospitals.  It's in red on that chart on testing. Like all the boxes in these charts, there are tabs that allow you to see the info differently, so play with them a bit.

Cases depicted above represent permanent residency of the infected person, and may not reflect where the person is located currently, or was located when exposed or diagnosed.
