[EN VIDÉO] Coronavirus versus influenza: the differences between them, their similarities At the start of the pandemic, Covid-19 was compared to influenza, with some calling it “the flu.” However, it is not. Since then, scholars around the world have collected their observations, relying particularly on observations of the Chinese.
In Brazos County, Texas, he catches a man Covid-19 Last February. He owns a black Labrador and a shorthair kitten, both of which were positive for the English type du SARS-CoV-2February 12, 2021, two days later Find out Their master. These pets They are the first animals to test positive To a variable Corona Virus.
The English variant has struck a dog and a cat in Texas
The Department of Veterinary Medicine began at Texas A&M University Summer 2020 project Led by Sarah Hammer, an epidemiologist. The goal is to understand the transmission of SARS-CoV-2 between humans and animals and its associated effects Health effects Of the latter, but also whether they could form a potential reservoir for virus. For this, scientists take samples from pets in homes affected by the Coronavirus.
In this specific case, the two animals showed no Sign of disease During the sample. The Genome It was sequenced by National Veterinary Services Laboratories and reconfigured on March 11th. It is indeed the English variant of the B.1.1.7 line. At the time of the result, the animal’s owner indicated that she had had bouts of sneezing without her gravity.
And it seems that the owner was the one who hit his four companions. Scientists are advising people who have tested positive for the Coronavirus to stay away from their animals, as appropriate for humans.
« Work by Texas A&M University indicates that pets can also be infected with SARS-CoV-2 variants. And because this virus can be transmitted between humans and animals, it is important for people with Covid-19 to stay away from other pets and animals, as they would for others to prevent the virus from spreading to animals. “Dr. Casey Barton Behravish, Director, explains One health office at Center for Disease Control.
COVID-19: Will our pets be saved?
Article published April 20, 2020 by Nathalie Mayer
In China, residents of provinces infected with SARS-CoV-2 have reportedly been ordered to dispose of their pets. Objective: to reduce risks Radioactive contamination Through infected dogs and cats. Does this scale make sense? Not sure, Pasteur Institute warns.
It is now widely accepted that an a bat It forms the primary reservoir for SARS-CoV-2 Coronavirus In charge of Epidemic From Covid-19. But the question that always arises is which role Pets Can play in a spread. Can they get sick? Acting as middlemen? Amplifiers? To provide a preliminary answer to these questions, researchers from the Pasteur Institute and the Veterinary School in Alfort (France) conducted a study On dogs and cats.
Recently Chinese study Not yet validated by peers – It has been suggested that SARS-CoV-2 can infect cats in particular. Who can even contaminate each other Across From Respiratory Drops. However, dogs spare. The findings of the researchers after inoculating the Corona virus in animals in the laboratory.
Little risk of infection
To find out the situation in real conditions, researchers at the Pasteur Institute tested 9 cats and 12 dogs, many of whose owners showed clinical signs compatible with the disease. Coronavirus infection. And two of them were even positive. Some animals showed signs of being infected. But none of them can be tested positive for SARS-CoV-2 by the method PCR. A method that makes it possible to detect the presence of the Corona virus in an individual and thus diagnose sick animals. The Serological tests – which are used to identify individuals who have developed immunity Against Coronavirus So I Was Sick – Also Not FoundAntibody In their blood.
The researchers confirm that these are preliminary findings. They still allow us to suggest our pets, basically Dogs and catsIt is not easy to be infected with the Coronavirus. Including when they live in close contact with an infected human.
No, pets do not transmit Corona virus to humans
There ” Not proof The health agency said on Wednesday that pets and livestock can transmit the new coronavirus ConsideredConfirming that it was ” Unlikely The virus is transmitted from humans to animals.
Futura article with AFP-Relaxnews was published on 16/03/2020
Dog condition test faiblement is positive » The new virus in Hong Kong at the end of February, when its master himself infected, raised questions about human and animal infection. So I brought ANSES (National Agency for Food Safety, Environment and Occupational Health) together ‘ Emergency “A team of experts is studying this issue and related pollution before swallow Meat.
« at Mild Scientific knowledge available, there is no evidence that pets and livestock play a role in the spread of SARS-CoV-2 », Concludes ANSES. Although a file SARS-CoV-2 CoronavirusThe disease that causes Covid-19 disease was born in bats before passing another ClassThen it is transmitted to man, his passage. ” From humans to other animal species seems currently improbable Reassured the experts.
They particularly highlight the fact that There is no virus From the same group as this new coronavirus has not been detected in a pet. Indeed, if in some species, the receptor that SARS-CoV-2 binds to is present to enter cells, this presence is not sufficient to allow Virus multiplication, ANSES explains, yet recommends additional studies to determine factors that allow this Repetition.
No contamination through the digestive system
Experts also believe that the detection of the virus in the nasal and oral cavities dog From Hong Kong not evidence of animal infection, indicating the possibility of Negative pollution (The survival of the virus on A. mucous Without repeating it). However, they call for additional studies to be conducted on this point.
With the exception of contamination of the farm animal, ANSES also excludes the possibility of virus transmission by eating meat obtained from such an animal. For experts, the only possible way to contaminate food is to treat it with a someone sick. The report says that in the current state of knowledge, pollution through the digestive system has been excluded. On the other hand, inflammation of the respiratory system during chewing. It cannot be ruled out ».
The agency calls for good hygiene practices and indicates that cooking at 63 ° C for four minutes can divide by 10,000 risk of contaminating a food product.
