Does lockdown really decrease Covid deaths?

It has become clear that a hard lockdown does not protect old and frail people living in care homes – a population the lockdown was designed to protect. Neither does it decrease mortality from Covid-19, which is evident when comparing the UK’s experience with that of other European countries.

PCR testing and some straightforward assumptions indicate that, as of April 29, 2020, more than half a million people in Stockholm county, Sweden (which is about 20–25 per cent of the region’s population) have been infected. 98 to 99 per cent of these people are probably unaware or uncertain of having had the infection; they either had symptoms that were severe, but not severe enough for them to go to a hospital and get tested, or no symptoms at all. Serology testing is now supporting these assumptions.

Lockdown only pushes severe cases into the future – it will not prevent them

These facts have led me to the following conclusions. Everyone will be exposed to Sars-CoV-2, and most people will become infected. Covid-19 is spreading like wildfire in all countries, but we do not see it – it almost always spreads from younger people with no or weak symptoms to other people who will also have mild symptoms. This is the real pandemic, but it goes on beneath the surface, and is probably at its peak now in many European countries. There is very little we can do to prevent this spread: a lockdown might delay severe cases for a while, but once restrictions are eased, cases will reappear. I expect that when we count the number of deaths from Covid-19 in each country in one year from now, the figures will be similar, regardless of measures taken.

Measures to flatten the curve might have an effect, but a lockdown only pushes the severe cases into the future – it will not prevent them.
