“The overall sensitivity of canine detection was 97% and even reached 100% in asymptomatic people compared to RT-PCR”, according to a study by the AP-HP (Assistance Publique – Hôpitaux Paris) and the D’Alfort National Veterinary School.
A method as reliable and much more pleasant than a swab in the nostrils. A study by researchers from the AP-HP (Assistance Publique – Hôpitaux Paris) and the Ecole nationale vétérinaire d’Alfort, published on Wednesday in the American scientific journal PLOS-ONE (Biblioteca Publică de Științe) and spotted by BFMTV,“It confirms scientifically the ability of dogs to detect an olfactory signature of Covid-19 “, details APHP.
This study was conducted from March 16, 2021 to April 9, 2021 in Paris, on participants aged 6 to 76 years.
“335 people were tested, 143 were symptomatic and 192 asymptomatic. 109 tested positive for nasopharyngeal RT-PCR, 78 for symptomatic participants and 31 for asymptomatic participants, ”it was reported. “The global sensitivity of canine detection has been 97% and even reached 100% in people who are asymptomatic compared to RT-PCR, “said the researchers. these dogs were trained to detect Covid-19.
Then to clarify how this test was performed: “Axillary sweat samples were collected via compresses lay under the armpits for two minutes study participants. They were then sealed in jars and then they were sniffed by at least two different dogs. If at least two dogs were sitting in front of a jar, the sample was considered positive. If “a dog showed great interest in the sample” but did not sat “not immediately”, the sample was also considered positive.
This method of detection, even if it were to be used, would nevertheless pose certain constraints. In fact, dogs are about to enter Covid-19 instantly. In addition, in the face of too many people, these animals can get scared. Finally, they also run the risk of being infected by viruses.
