Covid Tracker
Below are the current cumulative cases and deaths in Maryland, the DC area,
and selected other counties that are important to me.
Notes and Caveats
Doubling Time refers to the prejected number of days that cases or deaths will
be expected to double. The longer the timeframe the better. As a comparison:
- The sharpest growth rates in cases in Japan, Singapore, and Hong Kong
came when cases were doubling after 7+ days, while China, Spain, and Italy were
doubling very 2 days.
- At their worst, deaths in Lombardy (N. Italy), Madrid, and Catalonia
(Spain) were doubling in 1.5 days. Wuhan was doubling about every 2 - 2.5 days
Cases provide more information to be able to judge the rate of spread, but
the availability of test kits varies by state and county, so the data is unreliable.
Deaths are (thankfully) low in most counties, so predicting a rate of growth is
difficult. Take Doubling Times with a healthy grain of salt until the cumulative deaths
reach 10 - 20.
