I don&#8217;t have the attention span to have thrived in that particular profession.<\/p>\n<p>As another disclaimer, even though I&#8217;m going to talk about COVID-19, I&#8217;m not claiming to be anything other than your typical armchair numbers person inspired by a global pandemic to ponder infectious disease. Except I guess it&#8217;s more like &#8220;standing desk&#8221; or &#8220;floor-sitting&#8221; numbers person, because I don&#8217;t own much furniture. But that&#8217;s another story.<\/p>\n<p>All that to say,\u00a0<a href=\"https:\/\/www.oregonlive.com\/coronavirus\/2020\/04\/oregon-got-half-the-20000-coronavirus-tests-the-governor-touted-theyre-not-being-put-to-use-either.html\">this article<\/a>\u00a0is inspiring a digression on orders of magnitude and the importance of context in interpreting numbers. The highlight is that the Governor of Oregon erroneously claimed a deal with Quest to buy 20,000 test kits (turns out the deal was for &#8220;just&#8221; 10,000):<\/p>\n<blockquote><p>Brown hastily announced a deal that wasn\u2019t finalized and trumpeted an eye-popping number of tests that didn\u2019t prove to be accurate.<\/p><\/blockquote>\n<p>Oregon, like much of the country, has a testing and tracing problem that it does not appear to be solving, which I think is what the author of the article really wanted to say. I&#8217;m not going to try for a precise definition of &#8220;eye-popping&#8221; here, but I do imagine the term would satisfy the following:<\/p>\n<ul>\n<li>If <em>x<\/em> is an &#8220;eye-popping&#8221; number, than <em>x\/2<\/em> is also an eye-popping number.<\/li>\n<li>If <em>x<\/em> is an &#8220;eye-popping&#8221; number, then <em>x<\/em> is probably at least an order of magnitude larger than 20,000.<\/li>\n<\/ul>\n<p>For context, 20,000 is approximately the number of tests Oregon had already completed at the time of the article&#8217;s writing (April 8). This is not a particularly large number relative to Oregon&#8217;s population (~4.2 million) or relative to its geographic location in the context of this pandemic (sandwiched between our dear neighbors Washington and California, two of the first &#8220;hot spots&#8221; in the nation). Or relative to the length of time the disease has probably been spreading locally.<\/p>\n<p>Which is to say, if Oregon had conducted 40,000 targeted tests as part of an early and ongoing test and trace program, I guess we wouldn&#8217;t be in bad shape here. Provided we had combined that with giving resources (e.g., food, basic sanitation supplies, housing) to those under quarantine.<\/p>\n<p>But, together with the rest of the US, we didn&#8217;t. Are we even in catch up mode? I don&#8217;t have a beef with the gist of the above article, which goes on to point out that Oregon, at least, doesn&#8217;t seem to actually be ramping up its test and trace capabilities. Despite what the governor had claimed.<\/p>\n<p>As the news devotes more and more time to antibody tests and visions of the recovered &#8220;reopening the economy&#8221;, it&#8217;s worth pointing out that even in the areas that are hardest hit, the group of people who have been infected with and recovered from COVID-19 is really quite small and we don&#8217;t yet know if the immune response is robust or lasting.<\/p>\n<p>Put another away, most people are still susceptible to infection, and those who have already been infected and recovered may be susceptible to reinfection far sooner than we&#8217;d like.\u00a0(And here I don&#8217;t mean a measly &#8216;most&#8217;, but more like oh, I don&#8217;t know, well over 99% of humanity.)<\/p>\n<p>Oh, and let&#8217;s not forget that viruses mutate.<\/p>\n<p>This <a href=\"https:\/\/www.vox.com\/2020\/4\/13\/21215133\/coronavirus-testing-covid-19-tests-screening\">Vox article<\/a> is worth a read.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>As a full disclaimer, I&#8217;m terrible at arithmetic.
