Rare and Common Presentations and Conditions
What does the above even mean?
There are a very large number — thousands — of individually rare conditions. So even though any single given rare condition is only rarely seen, having any rare condition whatsoever is relatively common. On the other hand, there are a limited number of truly common conditions: the common cold, reactive depression, and back pain, for example.
If we consider a rare presentation of a common disease to be defined similarly, this would mean that this would likewise be about a 1 in 1500 presentation of a common condition. If 1/3 of the US population has at least one common condition at any given time, this means that about 100,000,000 persons in the US have a common condition; if 1/1500 had a rare presentation, this would in turn mean that there are only about 70,000 persons with rare presentations of common conditions per year. This is much less than the over 25,000,000 with a rare condition.
So it turns out that, based on prevalence data, the number of people with a rare but otherwise typical condition significantly outnumbers the number of people with only a rare presentation of one of the common conditions.
The anxious patient doing an unfortunate Internet search for their diagnosis may err because they choose a rare presentation of a rare condition over the common presentation of a common condition from which they suffer, and not because they find a rare condition that truly fits them best.
The machine runs on: "The Machine Stops" by yearend in 2021, we hope?
If you've never read E. M. Forster's classic The Machine Stops, written when the telephone was cutting edge tech, 2021 is the year you should.

Let us not forget that social distancing is not social. Quarantine and related distancing is a necessary evil, and necessary evils are still, well, evil.
The dysfunctions promoted by our isolation under fear of the coronavirus should not be permitted to outlast the need for isolation. There are far better solutions incoming, such as immunization.
