How many years of life are lost to covid?

A few weeks back I wrote an article about how high the risk of dying from covid is. I mentioned that a senior representative of the World Health Organization (WHO) had recently said that the WHO’s best estimate was that roughly one in 750 people who get infected die of the disease. I also mentioned a study published by the WHO, authored by professor John Ioannidis at Stanford University, which was based on antibody data. That study estimated that the mortality rate for covid was around 0,23% overall, which would mean that roughly one in 430 people who are infected overall die of the disease, and 0,05% for people under 70, which would mean that if you’re under 70, the risk of dying of covid is about one in 2,000. read more

New evidence on the effectiveness of lockdown

A few weeks back I wrote an article about an observational study published in Lancet that, among other things, looked at whether there was any correlation between stringency of lockdown and the number of people who died of covid. It didn’t find any correlation, which suggests that lockdowns don’t work. That study did have some major limitations however. read more

Does lockdown prevent covid deaths?

A very interesting article was recently published in Lancet that sought to understand which factors correlate, on a country level, with covid related outcomes. The study was observational, so it can only show correlation, not causation, but it can still give pretty strong hints as to which factors protect people from covid, and which factors increase the risk of being harmed. read more

How accurate are the covid tests?

One of the most frequent questions I’ve been getting recently is how accurate I think the covid tests are, and in particular the PCR tests. As it happens, a systematic review has recently been published in Evidence Based Medicine that looks at the covid tests (both PCR and antibody), so I thought it would be interesting to look in to the evidence together. This article gets a bit technical and math-heavy in places, so please bear with me. I think the payoff is worth it. read more

A history of the Swedish covid response

The Swedish response to the covid pandemic has become one of the most talked about topics of the last six months, and there’s a lot of misinformation floating around. Since that’s the case, and since I keep getting asked what the situation on the ground is really like in Sweden, I figured I’d write up a little history, covering the key events from a Swedish perspective, and detailing exactly which restrictions were put in place at what time point, and why. read more

Covid-19: A Swedish care home doctor’s perspective

This is a guest post written by a colleague who works as a care home doctor in a small Swedish town. In other words, he is responsible for the wellbeing of frail elderly people living in care homes. He has treated a lot of patients with covid-19. Since the situation may be different in some other countries, I think it is useful to know before reading the article that in Sweden, people stay in their own homes until they are very close to the end of their lives. 50% of people who move in to care homes are dead within six months. read more
