Bearing in mind the uncertainty factor—that we don’t really even know what we don’t know as of yet—stepping back for a dose of level-headed perspective seems like it might come in useful.
I’m a recently-retired Professor of Pathology and National Health Service consultant pathologist, and have spent most of my adult life in healthcare and science — fields which, all too often, are characterized by doubt rather than certainty. There is room for different interpretations of the current data. If some of these other interpretations are correct, or at least nearer to the truth, then conclusions about the actions required will change correspondingly.
The simplest way to judge whether we have an exceptionally lethal disease is to look at the death rates. Are more people dying than we would expect to die anyway in a given week or month? Statistically, we would expect about 51,000 to die in Britain this month. At the time of writing, 422 deaths are linked to COVID-19 — so 0.8 percent of that expected total. On a global basis, we’d expect 14 million to die over the first three months of the year. The world’s 18,944 coronavirus deaths represent 0.14 percent of that total. These figures might shoot up but they are, right now, lower than other infectious diseases that we live with (such as flu). Not figures that would, in and of themselves, cause drastic global reactions.
Initial reported figures from China and Italy suggested a death rate of 5 percent to 15 percent, similar to Spanish flu. Given that cases were increasing exponentially, this raised the prospect of death rates that no healthcare system in the world would be able to cope with. The need to avoid this scenario is the justification for measures being implemented: the Spanish flu is believed to have infected about one in four of the world’s population between 1918 and 1920, or roughly 500 million people with 50 million deaths. We developed pandemic emergency plans, ready to snap into action in case this happened again.
At the time of writing, the UK’s 422 deaths and 8,077 known cases give an apparent death rate of 5 percent. This is often cited as a cause for concern, contrasted with the mortality rate of seasonal flu, which is estimated at about 0.1 percent. But we ought to look very carefully at the data. Are these figures really comparable?
Cause for concern? Sure. Taking reasonable, appropriate precautionary measures? Of course. The kind of irrational panic response we’ve seen of late—upending society wholesale, wrecking the economy, throwing millions out of work, passively forsaking rights and liberties that can never be regained without bloodshed? Sorry, I just can’t see it. The good doctor makes a lot of sense to me here. But YMMV.

To understand where this is going, we need trend data along with overall numbers. But data on who has it is unreliable, since it’s based as much on testing as it is on infections. The only reliable trend data is on deaths (except Italy, where anyone with COVID-19 who dies of something else is called a COVID-19 death), and that only from advanced countries that are reporting accurately. What’s the trend line in deaths in the US? What’s the trend in other countries doing lockdowns? What can we learn from other places taking this seriously and doing reasonable things, like Taiwan and South Korea?
Sounds reasonable. I’ve thought along those lines pretty much for two months now.
