Canine units are trained in Mérida for Covid detection – The Yucatan Times


On the strength of the positive results obtained during the Covid-19 pandemic, the Mérida Unit of the Center for Research and Advanced Studies (Cinvestav) will develop in the medium term a project for a “Canine training school for the biodetection of transmissible viral diseases “. ”.

Dr. Victor Manuel Vidal Martinez, researcher of this unit, mentioned that for a month two dogs sniffed 250 people daily, reaching five thousand, and three individuals were detected infected with SARS-CoV-2, including the cases were confirmed by laboratory tests.

He added that this week he will take one of the dogs with Dr. Matilde Jiménez Coello, specialist of the Regional Research Center “Dr. Hideyo Noguchi” of the Autonomous University of Yucatán (Uady), to develop the project “Detection of Covid-19 using trained dogs”.

He clarified that the filters for the detection of various pathologies are not only useful for Covid-19, but also for the detection of the vine virus, that is, the pathology that affects the grape that produces grapes. Red wine.

The Cinvestav researcher acknowledged that the cost of having a dog training school is high, but there is interest in dog training in Yucatán and pointed out that in the medium term there will be a branch of the school currently located in Hermosillo, Sonora.

He said virus disease detection can be implemented in airports, hotels, restaurants and schools.

He recalled that in November 2021, work had been announced to characterize and isolate the volatile compounds (which become vapors or gases) present in the sweat of people positive for Covid-19, to develop a formulation that will allow more effective training of dogs accustomed to detecting the disease.

“Dogs are able to detect in seconds whether a person has Covid-19, making them an affordable alternative for use in industries, shopping malls, airports or at sporting events attended by many people. “, did he declare.

Vidal Martinez mentioned that with the data obtained, dogs have a 71% to 85% success rate in identifying Covid-19 positive cases from sweat samples, which is above the limit. maximum detection of antigen tests, which is 72%.

Additionally, dogs trained at the Obi-K19 school (in Hermosillo) have been found to be able to identify the new coronavirus infection in people up to three days before it is detected by methods diagnosis and the first symptoms appear, so the use of canines to prevent the spread of the disease could be of greater help.
