Les zoonoses : vers une recrudescence des virus transmis de l'animal à l'homme ?

Added: 2026-05-21

[00:00:00]Waking up with a doctor at your bedside is reassuring; he's there.

[00:00:04]Hello Dr. Daniel Simea.

[00:00:08]Hello Frédéric. Hello everyone.

[00:00:10]Yes, I say reassure us because it's true that right now, well, there are concerns.

[00:00:16]We wanted to talk about [unclear], which is an infectious disease that has passed from animals to humans. This is the case with an virus. Let's take a look at its evolution. Are we out of this or not?

[00:00:28]In any case, we're not going in there.

[00:00:30]We don't know if we're out of it, but for now, fortunately, it seems to be a concern that is receding a little, but it is indeed a good example of all these infections that pass from animals to humans either through a virus, a bacterium, or a parasite.

[00:00:53]So there are zoonotic pathogens.

[00:00:57]Let's remember why this term exists, what exactly does it mean?

[00:01:01]You've already said that a little bit, haven't you?

[00:01:03]Yeah.

[00:01:04]Yes. Yes. The zoo, that's life, that's animal life, right? When you go to a zoo, that's what it means. And above all, it means that we are part of this living system, right? Uh, infections, lesions, uh, which affect humans from animals, show us that we are in constant and permanent interaction and that we are part of nature. There is a concept that is rising at the moment which is the concept, it is an Anglo-Saxon term of one else, we could say one health but it is the international term which means that we are part of the environment and when we modify the environment, when we modify it too much well we expose ourselves to a boomerang effect and in particular a resurgence of these infections, of these zonoses which which are not new, you know. which are lost in the mists of time but which risk becoming increasingly important.

[00:02:08]Yes. And we know a little about how it spreads to humans. What is there in direct contact? Food, water, the environment – there are all modes of contamination.

[00:02:18]If we think of the disease of lime for example with thics, well it is a bite from the parasite that will infect us. If we think of avian flu, well, it's obviously transmitted via the respiratory route, or the anvirus that has occupied us these past few days. It can also be transmitted via the respiratory route, and it can also be transmitted via the digestive route, like Laeria. You know this disease, they say it infects cheeses but before infecting the cheese it infects the young animals and it is through the young animals that Laeria passes into the milk and it passes into the cheese with poor preparation conditions of course. So all routes of contamination are possible and it's true that this is a concern. We should also [clears throat] interview much more, much more I think [clears throat] at the highest level, interview veterinarians, my fellow veterinarians who are really the doctors of life, right. We, uh, doctors, we only treat one type of animal. They have a vision of life that is often much more relevant.

[00:03:31]Well, we'll be talking about that tomorrow with Annor Brami, another veterinarian.

[00:03:36]It will be at the same time. We'll make the connection then. I will ask him the question on your behalf. Just to explore one of your points a little.

[00:03:44]Daniel Sima, you say that the origin of ceos lies in the modification of our environment. That is to say [grunting] for example, let's take the point of view of bird flu or just the flu. The flu is [clears throat] not quite a zonosis since transmission now occurs between humans, but birds in general serve as a reservoir for the flu virus and for avian flu of course the risk is always above us.

[00:04:19]Well, in these cases, intensive farming does indeed increase the possibility for these viruses to multiply, to form what is still called, using a very French term, a cluster, and therefore to pose a problem with all the economic consequences as well. We see this with avian flu.

[00:04:40]Yeah, that's a concrete example. Thank you Dr. Daniel Simeeka for this awakening at our bedside. It is 6:29 am. Ah.
