Lice, bedbugs, fleas, mites, mosquitoes, ticks, crab lice, which we believed for a moment we had gotten rid of, once again proliferate.

Scientists point the finger at global warming, our too well insulated homes, our lifestyle changes, but also the genetic mutations of these invaders. If some parasites cause minor afflictions, others are vectors of very disabling diseases such as Lyme disease. Embark on a scientific investigation to understand the unexpected return of these bloodsuckers and the potential risks to our health.
