This is Don Samuels' COVID19 Cumulative Page
Updated: Sept 5, 2020 1200 MDT
Data from Arizona, Florida and
Georgia can not be trusted due to interference from
Starting April 26, this page will no longer be the home covid
page, but rather the "cumulative" page
New: US data transitioned from Johns Hopkins to New York Times.
Given the lunacy of voting in Wisconsin, I added in Wisconsin to
see if there will be a bump 14 to 21 days from April 7
Thanks for reading. Please give me
For regular readers,
please take a look at the Rolling 6 Day
average of reported deaths

This page is to show COVID 19 progression in ways I have not found
elsewhere on the web.
The graphs below shows number of deaths of the US and Italy. The US
is offset from Italy by the number of days shown in the graph. This
allows a possible glimpse into the future of where the US will be by
The data comes from Johns Hopkins (more on that below)
Exponential line changed from 1.35 to 1.33 which seems to be
where the US is.
Here is the US graph:
US not flattening as fast as Italy. Rolling graph here may be better to look at
NY is the US version of Italy. All state
graphs will show NY
Here is Colorado, first because that is where I
Polis has extended lockdown until April 26.
- Note does not include the latest update that the first death
was early February, not early March
Don't read too much into Idaho, small number of deaths.
April 7, 2020, day 20 was primary day for Wisconsin
France (for Dominique)
Ireland vs Italy
Smaller country, trend lower than Italy
I added Norway to this plot as some people/organizations believe
that the soft lockdown of Sweden is working. Norway is a similar
country to Sweden, with half the population, same genetic makeup and
has a stronger lockdown in place. It while the delta in the trend
here is striking, it shows up even better on the rolling average charts
The Johns Hopkins data is an csv file that
can be brought into excel. There is also sql capability.
Unfortunately their field format changes frequently so one has to
look at the data today to see if it is in the same format as
yesterday in order to chart.
I have chosen to plot total deaths as that number is much more
reliable for comparison of countries than "confirm positives". In
my stupid state of Colorado, there is for all intents and purposes
no testing at all. A number of the positive results that are
posted on the Colorado government website are classified positive
based on symptoms only, and they do not break out how many are
from the Reverse Transcription-Polymerase Chain Reaction test or
from symptoms. Deaths, while not 100% accurate should be a more
reliable indicator. As the deaths climb, so does the demand on the
health care infrastructure.
The Johns Hopkins death data is here (at least as of March 25):

You can go up a few directories here:
and work your way through other data and other visualizations.
Another site I use, which is updated between midnight and 2am
London time is here:
Hundley Lag Charts
The Financial Times Chart
Neat graphs out of University of Washington showing peaks by
state, and I think updated either real time or daily
I will add more as I find good ones, and try and update the
above chart daily.
