How do we get out of lockdown? The president has set a date, 11 May, but the plan is a bit short on details at the moment.

There are signs of tension, reports of vandalism and some clashes with police in parts of the banlieue, where some large families live in cramped conditions and many young people have strained relations with the forces of law and order.

Last night shots from home-made mortars were fired at the police station in Champigny, which is situated on a housing estate in the Bois l’Abbé neighbourhood. There were two incidents, one just before 1.00am, the other at 3.30am, according to reports.

A CRS riot police officer was slightly injured and a police vehicle damaged.

The attackers fled the scene and have not been caught.

Videos have been posted online, including one apparently filmed by the attackers.

Raphaël, the council employee who phones to check on Mum every day, says that isolation is taking its psychological toll on some of the elderly people he talks to. One old lady was desperately sad not to have been able to hold her great grand-daughter, who has been born while lockdown has been in place.

The latest news is that lockdown exit is likely to be applied differently in different parts of the country – so there should be relatively tough restrictions in the Paris region for some time yet.

The president is considering a déconfinement that varies according to how local authorities judge the situation in their area, sources have told Le Monde, which comments that “Emmanuel Macron is not as Jacobin as people think”, according to his supporters.

In hypercentralised France it really is quite daring to leave such initiatives to the regions. But it makes sense, given the disparate effect of the epidemic.

Along the Atlantic coast the rate of hospitalisation it between 0.9 and 1.9 per 1,000, with rural areas less affected than those where the cities of Rennes and Bordeaux are situated.

Val-de-Marne, where I live, seems to have the highest rate in the country, at 14.9 per 1,000, although Paris has a higher per capita death rate – 6.0 per 1,000, compared to 5.8 per 1,000 here.

Although the proportion of their population in hospital is lower, the death toll in Haut Rhin and Territoire de Belfort, in the east, is even grimmer, 8.5 and 10.0 respectively.

Paris has the highest total of deaths – 1,288, compared to 817 in Val-de-Marne, 646 in Haut Rhin and 140 in Territoire de Belfort.

Whichever way you look at it, the Paris region, with its tightly packed population and high infection rate, is going to have to enforce more precautions than the rest of the country.

Those will probably include enforcing wearing masks on public transport. The worldwide controversy over their value continues, however, with the WHO repeating its assertion that they are not useful to people who are not infected while the French Académie de Médécine has called for them to be made obligatory in all public spaces as from now.

In any case, it will be back to business as almost usual on 11 May. Economy Minister Bruno Le Maire wants all shops to reopen, but not bars and restaurants. On the other hand, there might be regional disparities, he says.

National health boss Jérôme Salomon says that social distancing and other precautions will be with us “for a long time”.

Some 61,700 lives have been saved by France’s lockdown, according to a study published yesterday. The health service, especially in Ile de France and the Grand Est, would have been swamped, with 100,000 intensive care beds needed, it estimates.

The report in Le Monde prompted one grumpy early-riser to denounce the publication as “propaganda and disinformation”. Not being under lockdown is “not a synonym for an orgy or a Covid party”, the commenter said, pointing out that the death toll was not nearly that high in countries that have not instituted lockdown.

But there are other variables, notably the extent of testing in Asian countries that were better prepared than Europe. And, as Le Monde points out, the recent rise in the death toll in New York, which was slow to enforce lockdown, and in Sweden, where it has not been implemented, show that the measure “has saved numerous lives”.

France’s Covid-19 death toll now officially stands at 21,344, 544 in the past 24 hours. 29,741 people are in hospital, down 365, 5,218 in intensive care, down 215. 40,657 people have been discharged from hospital.
