Second wave of Covid-19: the large check

We might have requested him the query six months in the past, Antoine Flahault would have "intuitively" answered no. However right now, this public well being specialist is satisfied: mass testing, even when the virus is drowsy, is the precise technique to undertake. "Wherever the assessments have been deployed early and forcefully, corresponding to in Taiwan or Hong Kong, now we have seen a greater managed wave and far decrease mortality," says the epidemiologist. To keep away from any return of the epidemic, it’s essential to display screen frankly. "

In France, even when the variety of new every day circumstances of Covid-19 stays at a low degree (541 this Tuesday), the Minister of Well being, Olivier Véran makes no secret of it: the chance of a second wave is " not negligible ”, he confided to our colleagues within the World. Well being institutions, companies, integration facilities, colleges, crèches, households … the 130 lively clusters scattered in virtually all areas sound like reminders.

So the federal government is accelerating the motion. As quickly as a territory wipes the primary drops of the virus, the instruction is to check there on a regular basis. Together with, typically, individuals with out signs, opposite to its first suggestions. In Normandy, free and non-prescription screening facilities have been arrange within the car parking zone of a shopping mall or in a village corridor.

In Ile-de-France, the beginning of an experiment in 32 municipalities was given. Goal: to hold out a PCR – this lengthy cotton swab inserted within the nostrils – to almost 1.four million individuals to determine "sleeping clusters" whose awakening might be painful.

"We nonetheless need to persuade individuals to go there!" Notes a physician. At present, the Directorate Common of Well being tells us that 250,000 assessments (at round 60 euros per unit) are carried out every week in France. " Ah sure ? Weren't we alleged to be 700,000 after the deconfinement? And much more the next month… a bit like in Germany? Are we to grasp that the division instructed us to arm ourselves with reagents, with a purpose to obtain this consequence? If François Blanchecotte goes on with ironic questions, it’s as a result of the president of the Nationwide Syndicate of Biologists "now not actually understands" the present method.

"Searching for a needle in a haystack"

“Earlier than, there was a constant path: we detected a symptomatic case, then the 20 to 25 individuals round him if it was optimistic. It made sense, continues François Blanchecotte. Now it's like searching for a needle in a haystack. The long run will inform us if doing so, at random, together with geographic, has an impact on the circulation of the virus… ”

Nevertheless, in accordance with Antoine Flahault, these large-scale assessments have a optimistic impact. “It should drain individuals who wouldn’t essentially have consulted their physician for a small cough or fatigue. Nevertheless, there, if it proves optimistic, self-discipline might be triggered robotically. Everybody will say to themselves: Bblood, who’ve I seen in current days? and isolate your self at dwelling ”, is satisfied the epidemiologist.

Like many medical doctors and biologists, he now pleads for a technological growth of screenings, much less restrictive than swabs within the nostril. “If we had, for instance, dependable and cheap saliva assessments, we may actually do mass testing. "
