Three basic test types are the focus here, and it’s these we will need to have mass-produced and distributed to a significant percentage of the population. Anything less risks prolonging lockdown or making the relaxing of lockdown a gamble. The gamble may pay off, but it may also end up with a death toll in the millions.

Whether you back “gamble!” or “don’t risk lives!” – and where this preference changes, along the infection + fatality + recovery progress line – it’s a question for individuals and its answer is more about your own personality and outlook than any objective data. Some are more gung-ho about life’s ups and downs (everything is a risk, get living). Others are more socially minded about doing the best for the most (all in it together, we’ll beat this if we unite). Whatever.

Here’s the data. Three test types. A bunch of approved, clinical trial and in the pipeline tests. Best thing we can all do, gung-ho or group-first, is keep a close eye on the facts – not just the numbers but the medical supply chains, testing most of all – and hold to account anyone presuming to take authority (be it the President, State Governors, City Mayors, federal, state and city officials). Keep an eye on where the money is going. Keep an eye on where the supply chains aren’t working. Keep an eye on where the institutions are working and where they’re failing. Get loud about any incompetence, corruption, grift, bullshit misdirection, bogus propaganda, etc.

Stay safe.
