March 31. US Coronavirus Projections

March 31.  US Coronavirus Projections

From the White House Coronavirus Task Force briefing today, presented by Dr. Dolores Birx, shows how Washington and California have a slower growth rate because they started early on programs of social separation.  They believe that when all states follow this, they will flatten the curve of deaths per day.  This will reduce the 1.5 to 2.2 million deaths down to 100,000 to 240,000, or even below.  The IMHE lower projections assume that the social separation works for all of the states.  California is the bottom blue curve, which almost is mistaken for the X-axis.  The next low curve is the yellow Washington curve.  The top blue curve is New York, the the orange curve below that is New Jersey.

Today, the US passed four thousand deaths, to 4,079.  NY State led with 1,550, out of which 1.096 were in New York City.  New Jersey was next with 267, Michigan with 259, Louisiana with 239, Washington with 225, and California with 175.

The usual table of cases has the Domain, the number of Cases, and the daily Percent Increase.
