  Covid-19: New variant 'raises R number by up to 0.7'

name="Ro"
Plotting the number of cases is useful since a straight line indicated Ro is near 1.0.
However, reporting the percentage of positive tests is much more informative then
the number of positive tests, since the number of positive tests depends heavily
on the number of tests taken.  A constantly straight line increase of cases only
indicates that there is a large populace of vulnerable people who have not contracted
the disease.  It only indicates that the health care facilities will not become even
more overtaxed.

2020 April 23:
https://www.worldometers.info/coronavirus/coronavirus-cases/#active-cases shows
an inflection point and concave down portion after April 1in spite of more tests.
and https://covid19.healthdata.org/united-states-of-america shows a leveling from
April 7 to April 20  so things are somewhat stabelized, however we should not
relax until Ro is well below zero and the number of active cases can be controlled
with contact tracing.
