The science of epidemiology relies a lot on modelling because, for obvious reasons, controlled experimentation would be unethical. But in the case of Covid-19 we do have something approaching a real-life experiment – in that Sweden has declined to follow other European countries into lockdown. Instead, it has followed a policy which might be summed up as social distancing-lite. Gatherings of more than 50 people have been outlawed, closing theatres and putting an end to sports events. But children up to the age of 16 are still attending school, shops and restaurants are still open – albeit with rules preventing people standing up at the bar – and no police officer is to blow a whistle at you for sitting on a park bench.

Another day, and yet more evidence has appeared that could indicate the number of people who have been infected with SARS-CoV-2, the virus which causes Covid-19, might be vastly higher than official figures suggest. This time a Californian study suggests the figure in one county could be more than 50 times the number who knew they had had the virus. A team from Stanford university and other US universities recruited volunteers in Santa Clara County via Facebook adverts and produced a sample of 3000 representatives of the county as a whole. They were then invited for blood tests to detect the presence of antibodies to the virus. The result was positive in 1.5 per cent of cases. Adjusting for age, gender and ethnicity the results suggest that 2.

Coronavirus, we have been warned many times, has brought scammers out in force. But lobbyists are not far behind. Their activities may not be illegal, but they are pretty disgraceful nonetheless. Hardly had the coronavirus outbreak begun in January than my email inbox began to fill up with press releases claiming that the contagion was being spread by banknotes and coins — coming, er, from businesses with a vested interest in cashless payments. In Britain, the payments industry seized the moment to lobby the government — successfully — for the limit on payments via contactless cards to be raised from £30 to £45. The new limit duly came into effect on April 1.

It just keeps on getting worse. Like the death toll from Covid-19 itself, forecasts for the economy in the wake of the crisis keep on creeping upwards. Today, the Office for Budget Responsibility (OBR) forecasts that UK GDP could contract by 35 per cent by June if the lockdown continues until then, before 'bouncing back quickly'. Unemployment could rise, it says, by two million, with the unemployment rate climbing to 10 per cent. That is quite a shock given that on the eve of this crisis we were celebrating the highest employment ever and the lowest unemployment in 45 years. The 35 per cent contraction is making all the headlines today – as well it might.

This morning we have some data giving a little more insight into the great unknown of the coronavirus pandemic: just how widely among the population has SARS-CoV-2 – the virus which causes Covid-19 – spread among the general population. A team at the University of Bonn has tested a randomised sample of 1,000 residents of the town of Gangelt in the north-west of the country, one of the epicentres of the outbreak in Germany. The study found that two per cent of the population currently had the virus and that 14 per cent were carrying antibodies suggesting that they had already been infected – whether or not they experienced any symptoms.

Is there anything more ridiculous, when we have hundreds of thousands of workers sat idly at home to avoid spreading coronavirus, to be flying in fruit and vegetable-pickers from Eastern Europe? Yet that is exactly what is about to happen. Concordia, which supplies seasonal labour to UK farms from overseas, says it is looking to charter planes to bring in 10,000 workers from Bulgaria. Without them, it says, fruit and vegetables will have to be left to rot in the fields. Sure, there is nothing wrong with using migrant labour on British farms in normal times. Until a few weeks ago we had pretty well full employment; there were few Britons prepared to work in the field.

We have, of course, been transformed into a nation of hoarders and panic buyers. We know this because everyone keeps telling us. There are the queues around the block, waiting for Asda to open; the tearful nurse on Twitter who couldn’t get any food after a 48-hour shift; anecdotes galore about people loading loo rolls into their trolleys by the tree trunk-load, fighting over each consignment as it arrives. How much more civilised we all were – it has been claimed – during wartime. I’m sure there are people panic-buying and hoarding vast quantities of tinned foods, but is it all quite so bad as being made out?

It has become a received wisdom that coronavirus has forced Boris Johnson to morph into Jeremy Corbyn. Vast handouts to business, surging borrowing, open-ended commitments to NHS spending: there’s certainly a whiff of Labour policy in there. Some Conservative ministers even appear to see it that way; 'We'll find ourselves implementing most of Jeremy Corbyn's programme,' one of them told Robert Peston yesterday. But no, we have not ended up, by accident, with the government that we would have had if we had voted for Jeremy Corbyn in December. There is a world of difference between the measures that Rishi Sunak’s emergency measures and what Corbyn would have unleashed on the country.  True, borrowing is going to rise to eye-watering levels.
