  Another way to say it, almost 2 of 3 tests are positive :-(

  Also one of lowest test rates in the world, only testing people with serious symptoms

  Occasionally in some states the positivity rate is as high as 100%.

  Yes, and Peru is doing even worse I am afraid :-( Here is a representation of the percentages. https://twitter.com/Marco_Piani/status/1274793727568023556?s=20 … similar to what you have here. https://ourworldindata.org/grapher/covid-19-daily-tests-vs-daily-new-confirmed-cases-per-million?xScale=linear&yScale=linear&zoomToSelection=true&time=2020-04-24..&country=CAN~CRI~CUB~SLV~MEX~PAN~USA … Probably I will have to include some higher-percentage slopes :-(

  #COVID19 Worldwide: Trajectories in the Cases vs Tests (per capita) plane Somebody (in)famously said that the more you test, the more cases you find, so more cases found while increasing testing would not indicate a worse spread of the virus. pic.twitter.com/D2TkPAYcan

  And this situation is hardly going to change. @HLGatell along with Mexican authorities say testing is not useful to fight against Covid-19, that there is not sufficient evidence of this. Outrageous, right?

  The govmt policy is to test in order to confirm (rather than establish) a covid diagnostic. That's why "confirmed cases" is a meaningless figure in MX. It measures (limited) testing capacity, not number of cases.
