The Difference between Logarithmic and Exponential – Covid-19

Now, more than ever, it is important to know the difference.

“Flatten the curve” works for linear graphs. But we’re increasingly seeing exponential growth plotted on logarithmic graphs.

The notion of “flattening the curve” has become the popular way that people have come to understand quarantine measures. The idea is that the curve depicting coronavirus infections is rising sharply, but that if we socially distance and quarantine ourselves, we can flatten the peak of that curve and prevent the medical system from being overwhelmed.

But this idea is being plotted in two different ways: linearly and logarithmically. Logarithmic graphs make more sense for exponential curves like coronavirus cases and deaths, but they also must also be read differently than linear graphs.

Looks like New York and Detroit are pretty hot spots

People on Spring Break in Florida for the past couple of weeks were famously unconcerned with social distancing measures implementing in other areas of the country to help stem the tide of COVID-19 infections and save lives. Using cellphone location data from just the phones of the people gathered on a single beach in Fort Lauderdale, Florida, this video shows just how far those people spread across the country when they went home, possibly taking SARS-CoV-2 with them. They go everywhere.



Covid-19 Net New Deaths in Italy

Something to look at in the coming days. As Net New Deaths in Italy decline, we may be able to expect to see the same result within 10 days here in the States.

Confirmed cases include presumptive positive cases.

Recovered cases outside China are estimates based on local media reports, and may be substantially lower than the true number.

Active cases = total confirmed – total recovered – total deaths.

Point level: County level – US; Province/State level – China, Canada, Australia; Country level – other countries. All points (except for Australia) shown on the map are based on geographic centroids, and are not representative of a specific address, building or any location at a spatial scale finer than a province/state. Australian dots are located at the centroid of the largest city in each state.

Note: All cases of COVID-19 in repatriated US citizens from the Diamond Princess are grouped together. These individuals have been assigned to various quarantine locations (in military bases and hospitals) around the US. This grouping is consistent with the CDC.

Why it matters:

  • 50% of all confirmed cases have recovered as of 3/11/2020
  • Covid-19 is highly contagious, like the Spanish Flu of 1918, but far less deadly
  • Unlikely the Spanish Flu (a very similar H1N1 Avian strain of Influenza), the case fatality rate was 2.5% – but remember, that was 100 years ago.
  • The case fatality for Covid-19 is .6% – AND is it not deadly in most adults, so therefore, because fucking basic math, less fatalities will occur
  • Adults between the ages of 18 – 60 can be asymptomatic and should avoid contact with older adults (70+) especially those with Pre Existing Immunodeficient conditions
  • Avoid contact with people that have recently traveled to Iran, Italy, China, or the Pacific Northwest United States
  • The only reason to get tested is if you have been in contact with elderly Immunodeficient persons, you yourself have the flu, or you have traveled to or been in contact with people have
  • Wash your damn hands
  • Don’t touch your damn face
  • Be a smart person. Basic common sense will keep you alive and healthy
