District of Columbia average daily new cases

The chart below shows the trend of new case discovery for District of Columbia. Flattening the curve of new daily cases will help alleviate the burden on hospitals and healthcare workers and help ensure that patients that need critical care can get it.

Note: If testing is insufficient the above curve will underrepresent true case discovery. Nationwide daily testing per million residents is currently 336.1. Reported District of Columbia testing per million residents per day is 692.3.

District of Columbia average daily deaths

Deaths from COVID-19 are likely better reported than the true number of positive cases. As a result, the trend in average daily deaths from COVID-19 might be a more telling measure of progression through the outbreak than daily average positive cases.

COVID-19 testing statistics in District of Columbia

All measures below are rolling 7 day averages except Total Tests and Total Tests per 1M residents which are cumulative counts of COVID-19 tests as of the date reported. Testing statistics are dependent on high quality reporting of negative test results by states. I'm only showing this data for states that don't have implausibly low testing rates and that have an A reporting grade from the COVID Tracking Project.

A final word on this analysis

In order to manage the outbreak, states need to increase their testing capacity. As testing increases, the number of detections as a fraction of total tests (positive rate) should hopefully decrease over time. If a state is able to test widely enough (at least 300 tests daily per million residents, probably more) to drive the positive rate down (less than 5%) there may be the potential to manage a regional outbreak with isolation, contact tracing and quarantine South Korea has.

Please take my calculations and amatuer epidemiological speculations with a huge grain of salt as I'm moving quickly to get what I hope are meaningful measures online. There may be errors in my data and my thinking!

These statistics were inspired by posts on Calculated Risk and the Bondad Blog regarding metrics to track for COVID-19.

Last but not least, thanks to the folks at COVID Tracking Project for making this data available to everyone.
