For the moment, there is no remedy capable of preventing the diffusion of the virus in the organism and, a fortiori, of preventing its attacks on the lungs of the most fragile. While chloroquine has received a lot of attention in recent weeks – despite the lack of evidence of its effectiveness – many other molecules at least as promising are currently being tested.
To accelerate the discovery of a treatment, scientists are betting on a strategy called “repositioning”. “The idea is to use drugs that already exist and that could inhibit replication of the virus”, explains Pr Xavier Nassif, Director General of the Institut Pasteur de Lille. In other words, rely on chance. “If, luckily, a drug turns out to be effective, we could directly do clinical trials in humans,
