Recently, there has been a very tumultuous debate about a key point — how many people do we expect to get Long Covid after their initial infections? Headlines abound with terrifying statistics implying that nearly everyone will eventually get this condition, that more than 1/3 of Covid-19 sufferers are still suffering, and that we are all essentially doomed to be sick.

However, the reality is far more complex. A lot of this depends on definitions, and when you look at the data the proportion of people who have Long Covid is a very complicated topic, and may well be quite a lot lower than you’ve heard. Of course, a small proportion of a very large number is still a lot of people suffering, but the actual percentage may be quite a lot lower than scariest headlines suggest.

Let’s look at the evidence.

Definitions

Definitions matter in epidemiology. An expansive definition of a disease will always include more people, but may also reduce the usefulness of the term. A narrow one may be more useful clinically, but will exclude people who may be suffering a milder version of the same illness.

Take the ongoing debate about what constitutes hypertension (high blood pressure). On the one hand, setting the bar lower includes more people who will go on to develop serious…
