I see charts of the cumulative number of infections (‘the curve’) and the number of tests administered … but comparing the daily number of tests to the cumulative number of infections is not particularly meaningful beyond seeing that the increase in infections is still rather exponential.
A better visualization compares the cumulative tests to the cumulative infections (or, for less staggering numbers, the daily tests administered and the daily number of new infections identified). No, it doesn’t appear that ‘the curve’ is flattening. I’m curious to see, however, the impact of multiple states going into lock-down has in a week or two.
Looking at a number of infections, especially compared across the globe, provides a bit of a distorted view. Comparing countries by the percent of the population that’s been identified as infected instead of the raw number of identified infections avoids the appearance that small countries are less impacted (and that highly populated countries are disproportionately impacted).
I’ve had several situations now where a group is looking to start an online video meeting. To eliminate platforms that don’t support the number of people required, I put together this quick list. Teams and Zoom are, unfortunately, something home users are less apt to be familiar with … but it really is “click to join the call” easy.
Microsoft Teams (300)
Facebook Messenger (50)
FaceTime (30, but limited to Apple products)
Google Hangouts (10)
Hangout Meet has a 250 person limit, but only if it is part of the gSuite subscription. It’s not part of our school district’s education package. Not sure if it’s part of our Township’s government package. Update: Google is now offering paid Hangout Meet features for free through 01 June.

Testing Stats: https://www.cdc.gov/coronavirus/2019-ncov/testing-in-us.html
Interesting combination of data — there have been 13,624 tests (although the data points for the past few days is currently incomplete) and 1,663 infections. That means like 87% of the people who have been tested weren’t infected. Which could be that they’ve been tested before they are infected enough, or it could be that there are a LOT of uninfected people getting tested. Since the actual number of tests is going to be higher, the percent actually infected is lower.
