Coronavirus dashboard for March 22 This is a new daily or nearly daily update I hope to post, including the most important metrics to show how controlled – or out of control – the cononavirus pandemic is. Hopefully the numbers will move ever closer to the tipping point where the epidemic is under control.In order to bring this pandemic under control, and prevent both health and economic catastrophes, in my opinion the US needs 2 weeks of China (total lockdown, preventing community spread) followed by 1 month of South Korea (extremely aggressive testing). The metric to be watched for testing is a ratio of 15 tests administered for every infection found (the ratio at which South Korea turned the corner). Here is the update through yesterday (March 21)

Here is the update through yesterday (March 21)
Number and rate of increase of Reported Infections (from Johns Hopkins via arcgis.com)
- Number: up +7,123 to 26,747 (vs. +5,374 on March 21)
- Rate of increase: day/day: 36% (vs. 34.6% baseline exponential average per Jim Bianco) (and vs. 38% on March 21)
Jim Bianco’s excellent exponential projection from March 10, of a daily 34.5% growth in reported infections for the next 10 days has been almost exactly correct. I am using this as a baseline against which we can tell how well “social distancing” strategies are working as well as State-mandated partial and total lockdowns.
In the last five days, the rate of exponential growth has actually risen from about 28% to 40% and even 50%, probably due to increased testing being able to uncover more infections.
- Number: 44,068, up +7,414 vs. March 21 day/day
- Rate: increase of 27% vs. number of tests previous day
Comparison of rates of increase in documented infections vs. testing
- Infections +36% vs. Tests +27% day/day
Result: Infections continue to increase a faster rate than tests: i.e., we are falling further behind in testing.
Ratio of tests to positives for infection (from COVID Tracking Project)</strong
- Number: 44,068 new tests vs. 6,165 new diagnosed infections
- Ratio: 7.1:1
In South Korea, where aggressive testing has led to a near-total disappearance of new cases, the inflection point where the number of new daily cases plateaued was reached when the ratio of tests to new cases found reached 15:1. Any ratio less than that suggests that not enough testing is being done. Yesterday’s ratio of 7.1:1 is poor. We are way behind in the number of tests we are administering.
