An awful lot of people cannot afford a lockdown, ministers

So the lockdown continues. Why exactly is unclear. Dominic Raab said on Thursday that ‘the measures will have to stay in place until we clearly have the evidence that we have moved beyond the peak’.

This is a change from previous policy. Until now we have been told we were flattening the curve to ensure that the health service can cope with peak demand and save lives. This did not require moving ‘beyond the peak’ before easing restrictions, just flattening the peak to a manageable level.

What Raab surely should have been talking to us about is health service capacity and projections of whether it will now be sufficient. Have we now slowed the virus enough and boosted the health service enough to mean it won’t be overloaded? If so, we need to get the lockdown lifted, because it is insanely costly – now estimated by the government to have shortened 150,000 lives. The government and their advisers act as if they can afford to add extra weeks of lockdown just to be on the safe side. Maybe they can afford it personally but an awful lot of people cannot. The lack of urgency within government to get this thing over is palpable and deplorable.

Bizarrely, the government still seem to be citing the reported cases statistics as an indication of the number of infections and the spread of the virus, despite this having been thoroughly discredited by many experts.

At least, though, chief scientific officer Patrick Vallance did admit for the first time that the virus has probably already spread to far more of the population than is reflected in the reported cases. He also claimed, however, that most of the figures that have come out for this in different countries so far are ‘low single digit percentages’. It’s unclear what his source is for this, as in Germany it looks to be around 10 per cent, if the widespread testing they have done is anything close to representative of the general population.

Vallance also claimed that asymptomatic cases ‘could be around 30 per cent’, despite that the three main studies on this so far, in Vo, ItalyIceland and the Diamond Princess cruise ship, all show between 48 and 75 per cent asymptomatic cases. It’s a shame these briefings don’t come with references as the government at times seem to be reading different studies from the rest of us.

As far as I can gather, the basic issue now is a fear that if lockdown is relaxed the infection rate will shoot up again and overwhelm the health service. At the heart of this are two very questionable beliefs that are held almost as articles of faith by those currently managing the crisis. The first is that the Wuhan coronavirus if left to itself would very quickly spread to almost the entire population, leaving a large number of people dead, many of them avoidably so had they had access to life-saving medical attention. The second is that the severe lockdown we have imposed is effective in preventing this from happening.

Both of these beliefs bear little relation to the facts. Since, as looks likely, the Wuhan virus had been in many countries for weeks before it was detected, and lockdowns were imposed very late in its spread, there is little reason to think such measures bear much responsibility for limiting its growth. The lack of any clear relationship between the severity of lockdown measures in a country and the impact of the virus further supports this point.

What seems more likely is that for reasons inherent in the behaviour of the virus it does not spread to everybody, or everybody in one go, just as only 17 per cent of those living in close quarters on the Diamond Princess tested positive for the virus and only 15 per cent of the populations of Gangelt in Germany and Shenzhen in China were infected.

This would explain why the proportion of positive tests typically increases only slowly and tends to have a limit (different for each country) rather than continuing an exponential explosion until everyone has it. In Germany’s case that limit is around 10 per cent, and the slowing of the rate of increase (beginning on 13 March) occurred well before any lockdown measures were put in place (on 22 March) or had chance to make a difference.

The problem with believing that only the strictest lockdown measures are what are standing between you and a catastrophic spread of the virus is it leaves you fearing that you cannot lift them at all until you have an effective treatment or vaccine. After all, if only 10 per cent of the population has had it so far, and you believe that the only thing stopping the other 90 per cent catching it in short order (and at least one per cent of those dying, even more if the health service collapses) is your lockdown, then you will think that ending the lockdown is the height of irresponsibility. This seems to be where many people’s thinking is right now, including the government and their scientific advisers, and perhaps explains their wariness despite the monumental economic and social costs of continuing the restrictions.

This is why it is so important that people recognise that that is extremely unlikely to happen. This coronavirus did not spread exponentially to the whole population before the lockdown, it grew slowly towards a limit, and it will not do so afterwards. I’m no virologist so I can’t say why that is the case, and the virologists themselves don’t yet have a full understanding either, though they do say that coronaviruses have a typical prevalence of 5 to 20 per cent. But like most people I can read a graph, and I can see how the proportion of positive tests slows towards a low limit even before lockdown measures are imposed, and that tells me all I need to know right now. It tells me this virus does not keep on going but reaches a natural limit, and does so independent of political interventions.

Have the lockdowns slowed it down further? Presumably, to some extent. In a way that doesn’t really matter, at least for this outbreak. What matters is that government and the public come to see, sooner rather than later, that you don’t need a lockdown to avert a catastrophic contagion. Until we get to that point – which might only come by looking at how other places with less severe measures fare – expect restrictions in some form to stay in place.

  1. Could it be that for genetic or environmental/lifestyle reasons (or a combination) a certain proportion of the population is quickly vulnerable to being infected by Covid-19 and that, once a certain number of this group has been infected (and either survived or died), the rate of transmission naturally dips? It’s speculation of course by a layman and there must be any amount of factors which mean that one cannot view people’s immune systems as broadly similar on/off switches which would allow you to model transmission through a whole population in simplistic mathematical terms.

    But it’s vital that our UK government gets the clearest picture both of what has actually happened already in the population and (therefore) what can be expected depending on the various future policy options. And, as has been highlighted, a policy in which a lot of people are reduced to dire levels of poverty and stress for the disproportionate sake of avoiding the merest blip in mortality figures (if such a blip is even noticeable at all) would turn out to be a very serious misjudgement.

    The problem as I see it is that the government has attached itself so tightly to one frightening narrative that it could find it very hard to change tack if it should discover that their lockdown and consequent economic damage had little real effect on the progress of the virus. However, things are so serious that I would gladly accept a bit of spin about how essential the lockdown had been if it allows the government to step back and rescue the economy from a disaster that promises to ruin countless lives.

    A sound testing program cannot come soon enough. Can we hope that, once it becomes possible, the government is capable of organising it at lightening speed and acting rationally on its results? Let’s hope so!
