In Massachusetts, USA, five schools have started using dogs to help look for coronavirus in schools. Experts have experimented with dogs in trying to identify many illnesses and diseases as they have incredible sense of smell, which is far more developed than human smell. Also studies have shown that in some cases trained dogs can detect coronavirus more quickly than covid tests. The sniffer dogs named Huntah and Duke are two young Labradors that have been trained to recognise the smell someone infected with Covid-19 gives off. The dogs walk around empty classrooms, corridors and the cafeteria after the children have left the room. If they detect the presence of coronavirus they will stop, sit down and put their paw up on the desk or chair they think has the smell. The school has seating plans for classrooms and lockers and a system of children scanning a barcode at the table they sit at, in the lunch area. This means they can work out who was sat in the chairs and areas that are identified by the dogs. Children and staff identified are then tested to confirm if they have virus and follow the school’s Covid-19 procedures. When the dogs aren’t working they can meet and play with the pupils, which the younger children really enjoy, says Rick Medeiros, who manages the five schools. According to Mr Medeiros the system is working really well and other schools across the USA have now started using dogs too. This is an amazing innovation and one that should be emulated by several other countries as it will help reduce the spread of the covid virus with less human resource expended.
