VOICED : El Salvador entrena perros para detectar covid-19 en aeropuerto

The video discusses how dogs are being trained to detect COVID-19 at airports, specifically in El Salvador. These dogs can identify the virus by sniffing samples containing the sweat of infected individuals. The training focuses on three key parameters: autonomy, motivation, and concentration, which enhance the dogs' ability to detect not only COVID-19 but also other diseases like cancer, malaria, and dengue. The dogs' heightened sense of smell allows them to detect even the faintest odors, making them effective for early detection, including in asymptomatic individuals.
