San Diego (Daily Pakistan Online) - Police in the South American country of Chile have decided to enlist the help of dogs to search for corona virus patients. In order to prevent the spread of code 19 in the country, dogs have a fifty-fold greater ability to sniff than humans. Trained dogs can sniff up to 250 people an hour. Officials say the corona virus has no odor, but the infection causes metabolic changes in the patient's body, causing the dog to produce a special pattern of sweat. Corona patients can be easily identified.
