The genesis of the virus crucial to understand how it “invaded” us, according to the WHO – Insurance for dogs


The origin of the new coronavirus remains at this stage uncertain, but it is nevertheless essential to understand how the virus “invaded the human race” in a few months, explains a senior official of the WHO in an interview with AFP.

In late March, President Donald Trump and his Chinese counterpart Xi Jinping concluded an informal truce in the war of words between the two great powers on the origin of the disease.

But the truce quickly shattered.

The Trump administration, which accuses the Chinese authorities of having delayed alerting the world to the epidemic, now openly suspects China of having hidden a laboratory accident which would have been at the origin of the pandemic. What Beijing denies.

Without saying a word, Sylvie Briand, head of infectious risk management at the World Health Organization, nevertheless considers “interesting to know the origin of the virus to understand how it evolved”.

“It is a virus of animal origin transmitted to humans. And so we have to try to understand what made the adaptation of this virus allow it to invade the human species”, he analyzes. her in front of WHO headquarters in Geneva.

The first cases of SARS-CoV-2, the virus causing Covid-19 disease, were reported in late December in the Wuhan region of China. Since then, the pandemic has killed nearly 300,000 people.

Many researchers believe that the new coronavirus was born in bats, but scientists believe that it passed through another species before being transmitted to humans.

“The virus has multiplied in these animals, has transformed a little bit as these passages and finally resulted in a form of virus” transmissible to humans, said Sylvie Briand, who directed the program WHO influenza during the H1N1 pandemic in 2009.

– ‘Thousands of direct debits’ –

Tracing the origin of the virus, by finding its intermediate hosts, would, according to this French scientist, “prevent the phenomenon from happening again and avoid ping-pong phenomena” of transmission between humans and animals.

Because “each time there are these passages from one species to another, the virus can modify a little bit and that can have an impact for example on treatments (…) or vaccines which can no longer be effective enough, “she explains.

For the moment, many unknowns persist. And this, although there have been “thousands and thousands of samples” made, in particular on “many animals in the Wuhan market” but also on dogs in Hong Kong, she noted, stressing that these analyzes take time.

These samples are taken by the countries, underlines Ms. Briand, but the WHO “encourages them to share information between them” to speed up research.

Sylvie Briand, head of infectious risk management at the World Health Organization (WHO), on May 12, 2020 in front of the organization’s premises in Geneva (AFP – Fabrice COFFRINI)

The United States and Australia have called for an international investigation into the origin of the virus. More diplomatic, the WHO called on Beijing to “invite” to investigate the matter.

Shortly afterwards, China proposed in early May the creation of a commission under the aegis of the world health authorities to assess the “global response” to Covid-19, and only after the epidemic had ended.

The Chinese authorities have stressed that the approach should be validated beforehand by the World Health Assembly of WHO or its executive board – the two main organs of the international organization based in Geneva and which meet next week at their annual meeting.

These debates should also focus, according to Ms. Briand, on the need to “refine” the WHO health alert system, which only allows to declare whether there is an international health emergency or not while the previous procedure was in six phases, the last of which was the pandemic.

“We have to come up with a system that can launch alerts so that people prepare, but at the same time tell them if it is imminent or if it will happen in a few weeks or a few months and tell them better what they should prepare for, “she says.

Cymes presents dog screening experiences – Insurance for dogs


A very interesting experiment is carried out by the national veterinary school of Maisons-Alfort to detect people infected with the coronavirus. It was initiated by a professor from Alfort, Dominique Grandjean. The idea is disconcertingly simple. This is’use dogs’ noses to find out if someone has the disease, Covid-19, has symptoms or is asymptomatic.

We all know that dogs have a finely smelling smell that escapes us, poor humans. It is even the most developed sense of man’s best friend. The dog has 200 million olfactory cells when man has only 5 million. As they say, there is no photo.

This is why customs officials use dogs to detect, for example, the presence of drugs or banknotes in the luggage of traffickers. We even noticed that dogs are able to detect the presence of cancer cells in a human body. When there is a tumor somewhere, it releases metabolites, and a trained dog is able to react if it senses something. It would therefore not be the first time that these animals have entered the medical world to refer doctors.

The smell of coronavirus

However, all this requires a prerequisite: the coronavirus must have an odor. For the moment, the study is in progress. It started in early May and should deliver its first conclusions in a few days. But initial findings indicate that lThe dog reacts differently when there is a positive sample.

The tests are done in using the sweat of infected people. A dozen dogs are currently in training, mainly in Corsica since it is the Ajaccio gendarmerie which is at the forefront on the subject. The interest of the operation is that it would eventually set up mass screening, why not at airports. The idea may seem attractive on paper, but does not take into account other parameters.

Long dog training

First, the number of dogs likely to be used for public health. Difficult to assess how much it would take, but it is obvious that the ten dogs currently in training will not be enough.

Second, you don’t train a dog in this kind of exercise in 5 minutes. It takes time to make the animal understand that if it detects an infected person, it will be entitled to an additional pâté. Because if the dog has olfactory capacities superior to ours, as far as the brain is concerned, we are still far ahead. We can’t have it all.

Man, Animal, Climate and Environment – Insurance for dogs


One day, Man and Animal …

One day, and globally all over the world, Man domesticated the dog. It was over 12,000 years ago. Both shared the same prey, the same shelters. A friendship was created which continues to this day. The man was hunter-gatherer and moved in small tribes of about 70 members, according to the seasons, the flora and fauna that fed him, his tribe and his four-legged companion.

One day, another day, Man became interested in the seasonal plants that he could cultivate and produced every 3 to 6 months. It was 6 to 8,000 years ago. And Man cultivated cereals (barley, corn, millet, quinoa, sorghum, wheat, …), bulb vegetables (peas, lentils, beans, peanuts, …), fiber plants (flax, hemp, cotton, …) And cucurbits.

One day, therefore, from a nomad, Man became sedentary. He created fixed dwellings and protections against unwanted animals and the possible assault of other men by wanting his reserves.

And so, Man domesticated large mammals: sheep, goats and pigs 10,000 years ago, cows 8,000 years ago, horses and donkeys 6,000 years ago. And also the gallinaceae and the pigeon.

Thus, 4.000 years before JC, the Man had fixed what marks it still today: the fixed dwelling and its protection (village then city), its food of culture (cereals and vegetables with bulbs) and of breeding to which we must add the production of some “free” trees and fruits at the start and the abundant and available sea and freshwater animals (fish and crustaceans).

One day, therefore, Man prospered and multiplied. And when there were too many, he migrated. Thus the Gauls were 10 million around 400 and 300 BC. J.C, which brought them to Rome (-390), Delphi (-279) and Asia Minor. Depending on whether the climate was favorable, it multiplied (for example low Middle Ages, 1000-1500), or when the climate was unfavorable, it decreased by famine or disease (for example high Middle Ages, 500-900).

For thousands of years, humans have chosen and improved the flora and animals around them. He had domesticated some complementary herbivorous mammals, the other animals being generally considered as harmful or wild.

Environment and Nature

Man has therefore shaped, globally on Earth, the environment that surrounds him. Few wild spaces, free from human intervention. The Man intervened on all the spaces which were useful to him and which he could modify to his taste. The flora and fauna meet its needs and pleasures.

The Environment has encroached on Nature until it almost disappears. Nature is spontaneous, without the intervention of Man. The Environment is nature organized by Man.

Nature and the Environment have no borders, no barriers. Nature is not exempt from developing diseases in humans. In the XIVth century, the black plague would have been born in Asia from a drought which would have pushed the gerbils towards Chinese cities then the black rats towards the cities of Europe. Migratory birds displace non-zoonotic viruses which affect, for example, birds. It was said during confinement that Nature resumed its rights by seeing un-domesticated, wild animals, walking in the streets of cities, by seeing plants growing in deserted streets, by hearing the songs of birds.
Man believes he dominates the environment. This is not the case.

The Covid-19

We have learned a lot from the Covid-19 from human, animal, climate and environmental reports.

  1. Many pandemics or recent diseases have arisen from animals, most often from bats (paradoxical anagram: virus strain). Zoonosis, an infectious disease that spreads from vertebrates to humans, uses an intermediate host (pangolin for Covid-19, great ape for AIDS)
  2. To feed his animals, Man widens his Environment and cultivates new lands, therefore deforests most often and uncovers hosts of Nature and imbalance of ecosystems composed of Animals, plants, soils, reservoirs fauna harboring a biodiversity of microbes, some of which could be pathogenic for humans. Everyone remembers that the drying up of the wetlands of Alsace made the frogs and storks disappear.
  3. Now Nature is a whole that is balanced. Animals, insects and birds whose ecosystems are disturbed are getting closer to humans, vulnerable to unknown infectious agents. Among the zoonoses, have known tuberculosis, brucellosis, rabies and even small pox. And today SARS-Cov1 (or SARS, from 2002 to 2004 in Guangdong Province in China) and SARS-Cov2 are zoonoses. Tomorrow, with the notable acceleration of pandemics, there may be a Sars-Cov3 or a mutation of Covid-19 into Covid-20, the appearance of a new pathogenic microbe from an ancestor that was not not even a zoonosis transmitted from Man to Animal!

Man, Animal, Climate and Environment

Let’s go back: Man has bonded with the Animal. Not all animals. Man, Animal and Nature have a balance which is broken by the Environment created by and for Man.

In this balance, the climate can be versatile. But Man, by expanding his environment, especially through the city and transport, is upsetting the climate. We agree that in the current climate change, warming is linked to human activity which impacts on its environment. This warming can, for example, develop Chikungunya, Nile disease, and Zika in Europe and strongly impact humans. The drought in some regions can displace the terrestrial and aerial fauna towards other regions. The melting of the 20 million km² permafrost in the north of the northern hemisphere (North America, Siberia, Greenland). can move, attract or disperse species with consequences unknown to date for humans. Rising seas and oceans can change coasts and coasts and invade many cities. Etc. Man has a definite impact on Nature.

With the Covid-19, Man has shown that he is not capable of mastering everything. The Anthropocene – time when Man dominates Nature, commonly dated since the discovery of the steam engine – and the Covid-19 crisis reveal to Man that he cannot dominate Nature to this day, except at live in a totally closed universe, like a bubble, a huge greenhouse, where everything would be under his control. As it is not the case, Man must live with Nature.

The momentum that preceded Covid-19 for the past 30 years has been broken. It is called into question on energy sources, raw materials, the expansion of urbanized and concrete areas, etc. which impact Nature with pollution, the reduction of the living spaces of fauna and flora species, even transform Man by urbanizing it and weakening it towards nature [une question reste ouverte à ce jour : l’Homme plus en contact avec la Nature a-t-il été moins contaminé par le Covid-19 que l’Homme urbain ?]. The destruction of Nature is accelerating, entire “wild” areas, very many species are endangered.

Wanting to resume the movement as left in the fall of 2019 would be a profound and even fatal error.
The world of yesterday is not the answer. We must invent the world of tomorrow. You have to invent it now, today. In a year, when yesterday’s machine has been restarted, it will be too late.
The answer to Covid-19 is that the world of tomorrow is a balance between humans, animals, climate and the environment. It remains to locate this balance. It is not a question of planting a tree to give oneself a good conscience, but of imagining how this balance can live with what Man wishes according to his experiences and his knowledge.
What future do we want? Get to work quickly!

I’m going back to diving …

Sniffer dogs soon operational to detect the Covid-19? – Insurance for dogs


Dogs are already used to screen for various types of cancer (breast, prostate, etc.). Professor Dominique Grandjean, from the Maisons-Alfort Veterinary School, therefore had the idea of ​​using these animals to detect SARS-CoV-2, which is the source of Covid-19. This experiment aims to determine if the viral disease gives off a specific odor through sweat.

The dog is able to learn many orders and to adopt reflexes when facing them. The policyholdersdog insurance know this very well. This is the reason why this animal is used in many activities (hunting, rescue, drug detection, etc.).

Recently, Dominique Grandjean, who heads the veterinary service of the Pompiers de Paris, has started a test to find out if dogs can detect the coronavirus. These are canines already used to looking for people, explosives, etc. The experiment involves making them sniff a sweat sample from a patient infected with the disease. No treatment has yet been administered to prevent odor interference.

A practical and inexpensive screening method

Viral pathologies most often present an odor that trained dogs are able to recognize. If it turns out that this is also the case with Covid-19, it is possible to train canids to detect this disease. In fact, British researchers are already exploring this avenue.

>> CLICK HERE TO COMPARE ANIMAL INSURANCE <<

In France, Professor Grandjean has carried out similar tests. He believes that dogs can be trained in 5-10 days. As a result, the results will be available in several weeks and are likely to be conclusive.

The Hexagon already has nearly 3,000 sniffer dogs. They could be used to identify individuals infected with the coronavirus in public places such as airports and train stations.

Professor Grandjean specifies:

It would be an additional screening tool, not the only one of course, but given the number of tests that will have to be performed after the deconfinement, we may be very happy to have these dogs. We will not have them for May 11, but we can hope, if it works, to make them operational in the weeks that follow.

The first advantage of this solution lies in its cost. Indeed, it does not require massive investments. Otherwise, canine screening is particularly safe. In the case of cancers, for example, reliability is close to 100%. However, it is only about 70% with PCR tests used in Covid-19 research.

A promising track

The first test took place in Paris during the last week of April 2020. It involved 4 fire dogs already trained in olfactory screening. In particular, they have been trained to search for people and to identify and memorize the smell of drugs or explosives. Faced with familiar scents, they start to bark or lie down.

>> CLICK HERE TO COMPARE ANIMAL INSURANCE <<

Since May 1, the experiment has been carried out with other canines working with firefighters and gendarmes in Ajaccio (Corse-du-Sud). Concretely, this involves adding the smell of the coronavirus to those with which these animals are already accustomed. Professor Grandjean explains:

A dog that is looking for explosives is already initiated into forty molecules, if we add the Covid, it will ultimately only be a 41st for him to assimilate, it’s in his ropes, we don’t no need to start all the memorization work from the beginning […].

The training is therefore very fast, as the specialist adds. However, SARS-CoV-2 must involve specific molecules which will be found in sweat. For the time being, the experts are still at the experimental stage. As Professor Grandjean points out:

We presume, but even if it seems logical, we are not sure of anything yet, because there have been no publications on it.

In any case, these tests attract attention. Belgium, the United Arab Emirates and Morocco have already approached Professor Grandjean to find out more about his project.

The link between deforestation and the emergence of infectious diseases remains too little understood – Insurance for dogs


By overexploiting the environment, humanity reveals microbes “hidden in the shadows”. But this subject is the subject of too little research, alert researchers.

The exact origin of the SARS-CoV-2 coronavirus, which causes Covid-19 disease, has yet to be determined. If this research is still ongoing, scientists have suspected for months a recombination between the viruses of two different animal species, probably the bat and the pangolin, and which has caused a zoonosis, an infection of animal origin transmissible to humans. ‘To be human.

However, the deeper man enters wilderness areas, the more we exert pressure on flora and fauna, and the more likely these emerging infections will occur. This hypothesis, still debated in the scientific community, has gained momentum in recent weeks and has been reinforced by an analysis published in Frontiers in Medicine by experts from the Centers for Disease Control and Prevention (United States) . According to them, the more the natural habitats shrink, the more the wild animals concentrate on smaller and smaller territories or migrate towards inhabited areas, thus favoring interspecies infections. “Humanity must change the way it treats nature, or else more deadly pandemics than the Covid-19 will unfold,” they warn.

Kennel Cough

(BB + Pi) : It is a respiratory disease that mainly affects young dogs in collective breeding or in pet stores. Vaccination is particularly recommended for animals living in communities. The disease is caused by the association of several viruses and bacteria. Available vaccines protect against Parainfluenza virus (Pi) and a bacteria called Bordetella bronchiseptica (BB).

Spikelets

What is a spikelet?

Spikelets constitute the inflorescence of the large plant family of grasses. They are made up of glumes. These are weeds (wild oats, wild oats …) that are found everywhere.

The spikelet is the plant seed which, at a certain level of desiccation (dryness), detaches from the stem (it is the ginning) and is disseminated by the wind or the coat of the animals.

The spikelet is therefore dangerous when the desiccation of the grasses is significant, from June to September.

In veterinary medicine, there is a tendency to group any plant foreign body under the term spikelet.

How can it affect the dog?

When the spikelet is detached from its plant, it can fall on a dog’s coat and then risks progressing either through natural orifices (nostrils, ear canals, etc.) or through folds of skin. The spikelet then becomes a foreign body for the dog.

The spikelet peduncle is particularly traumatic and can puncture external tissues or mucous membranes. It is a very invasive foreign body.

What are the symptoms ?

The damage caused by the spikelet in dogs depends on its location and its stage of progression.

Three major locations are listed: the ear canal, the interdigitated spaces (between the fingers) and the eyes. But all other locations are possible: anal glands, nasal cavities, vulva, trachea …

Spikelets can be responsible for mild to severe disorders. Sometimes it is just a nuisance for the dog but it can also cause a significant local inflammatory reaction, even secondary lesions.

The ear canal is the most common location of the spikelet in dogs. It causes typical reactions: the animal shakes its head, moans if touched on the ear because the pain is severe. Then appear signs of otitis: purulent discharge, tilted head … Without intervention, the spikelet can continue to progress in the ear canal and perforate the eardrum.

When the spikelet is positioned between the fingers, it causes untimely licking of the tip of the leg and can then generate an abscess. After a few days, the dog will show lameness.

In the event of ocular localization, the animal will present signs of pain and discomfort (discharge, intense blinking of the eyelids …). Untreated, the spikelet can cause a corneal ulcer.

How to solve this problem ?

The management of a spikelet requires the intervention of a veterinarian.

When the spikelet has entered the ear canal, the treatment will consist of removing it using an otoscope and forceps. The veterinarian will then look for other spikelets, assess the damage to the ear canal and treat the reaction otitis.

Interdigitated spikelets may require a little surgery to manage the fistulas they have generated.

Likewise, spikelets located at eye level may require general anesthesia for their removal.

How to prevent spikelet “attacks”?

Several risk factors are known for this problem, in particular the breed of the dog and more particularly the nature of the coat and the wearing of the ears. Cocker spaniel, English springer, setters, bobtail, briard … are thus predisposed.

The way of life also plays a role with an influence of the activities of the animal (hunting) and its urban or rural housing.

Prevention involves careful monitoring of dogs when returning from walks in the summer season and prompt conduct at the veterinarian in the event of signs suggestive of a spikelet.

Dogs trained to detect coronavirus in humans: how does it work? – Insurance for dogs


How many people can France test each week after deconfinement? The figure is not yet clear, even if the government expects 700,000 tests per week from Monday, May 11.

So maybe to test, the government can turn to … dogs. In fact, five Malinois shepherds from the Seine-et-Marne firefighters are currently being trained by the Maisons-Alfort veterinary school to sniff the virus.

According to Dominique Grandjean, professor at the veterinary school, the breed of the dog does not matter in this experiment.

“All dogs are able to work like that and use their noses. The canine breed has such an olfactory faculty that the breed does not matter. We have a dominant Belgian Malinois shepherd, German shepherds, but we might as well have labradors, hunting dogs .. ”, he explains.

The first step is first to verify that people with coronavirus have a “special” odor.

“It was based on a study by Alabama, it was a few years ago. They had successfully used dogs to screen for cattle diseases. We had to determine what types of samples we were going to do to train the dogs. We turned to sweat because it is the only excreta that does not carry the virus in infected people. So we take the sweat under our arms. Then we train the dog, that is, put the smell in his nose. And then we will start to compare with smells, sweats that come from negative patients and we will see what is going on, “he explains.

Check the reliability of the tests

In procedure, it’s much the same as when a dog is trained to detect explosives. If the test and training of the dogs have not been completed, a first positive result should be noted. “We know there is a specific scent. And that was the big stranger, “he said.

“What will take longer is the validation phase. We will have to multiply the samples, that we multiply the passages of the dogs and that we note each time that we have a false positive or a false negative. And we will have to see what reliability we can have, ”says Dominique Grandjean.

The experiment is conducted simultaneously on three sites: Maisons-Alforts, South Corsica and Beirut in Lebanon.

Covid-19: dogs to detect carriers of the virus thanks to their scent – Insurance for dogs


Eight dogs from the Ajaccio fire and rescue services in Corsica are trained to detect the presence of coronavirus in the sweat of infected people. After several weeks, they may be able to identify in a crowd of people affected, a hope that nurtures several teams of researchers around the world.

“We already know that dogs have the ability to smell certain diseases. We also know that some viruses do have a specific smell.” It is on the basis of this observation that Dominique Grandjean, professor of the veterinary school of Maison-Alfort, in the Paris suburbs, interviewed there by 20 Minutes, launched a study to assess the capacity of dogs of the emergency services to identify people contaminated by Covid-19.

In the urine, stool, tears, saliva and sweat

Diabetes, malaria or certain cancers – lung, prostate – can be identified by certain dogs specially trained for this purpose. Experiments have been carried out on several occasions, with dogs which are trained by confronting the odor in question in the same way as for the search for people or explosives. The idea of ​​Professor Grandjean, also head of the veterinary service of the Paris fire brigade, is to reproduce this principle for the coronavirus.

A contaminated person, he observes, shows traces of his presence “in the urine, stool, tears or even saliva and sweat”, which are all vectors through which he evacuates the intruder. For this experience, the Maison-Alfort team and its partners decided to work on sweat, via samples taken from Covid hospital centers.

A game for broken animals to memorize smells

“The samples are placed in sterile jars then in a small hatch, near the dog’s favorite toy. Accompanied by his master, he comes to breathe this smell before recovering his toy”, describes Dominique Grandjean at our colleagues. Toy, because he has to choose a game and because the success of the dog will be sanctioned by a reward.

The first eight dogs are trained, by the Ajaccio firefighters, at the rate of a hundred presentations, each day, of pads impregnated with the sweat of patients. One more smell to memorize for animals that have several dozen in memory, for their work, nothing insurmountable according to the national veterinary school.

Research in Great Britain and the United Kingdom

The French, who are also associated with a Lebanese university, are not the only ones to work on this hypothesis. In Great Britain, Medical Detection Dogs, an association, pilots with two research and teaching institutions research of the same type, imagining after six to eight weeks of training having operational dogs. And being able to use them “to detect Covid-19 in airports at the end of the epidemic to quickly identify people carrying the virus”.

In the United States, the University of Pennsylvania is conducting a test with eight labradors., Which mentions shopping centers, hospitals, in general all the places with a lot of crowds. According to English researchers at the University of Durham, they could “sort” up to 250 people per hour, people who could be directed towards adequate care and more “classic” control.

In France, the first results of Pr Grandjean’s study are announced for mid-May. According to what it will be, the training of the dogs of the various rescue services – firefighters, Civil security – will be envisaged and their deployment planned, which could make it possible to hinder a resumption of the pandemic. This is all the hope pursued …
