Coronavirus showed its rampage on each passing day. Casualties due to pandemic virus crossed 1 million marks across the world.
All nations are in worrisome on how to handle the virus. It seems that vaccine to virus becomes long way to go. European Nations battles on second wave of coronavirus. Germany and UK are experiencing coronavirus resurgence. Positive cases are increasing day by day in some countries. Governments made their own possible approaches to contain the virus like plasma therapy and herd immunity.
Finland is doing another experiment to control the virus. It uses sniffer dogs at Airports to trace the coronavirus suspects. These dogs have an important job, sniffing out Covid-19 patients at Helsinki airport. Officials say they can detect cases in seconds with nearly 100% accuracy. The dogs can smell the pandemic virus before a patient has symptoms. The dogs give a positive diagnosis by scratching, lying down or barking. Scientists are not exactly sure how the dogs detect the virus, but it could be a sweat odour.
Finland's Helsinki-Vantaa airport is running a trial that lets people volunteer to be tested for the virus by the dogs. Passengers singled out by dogs are told to get a standard test to confirm if they are infected. Finland is second country after United Arab Emirates using the dogs to find out covid-19 cases. Scientists said any breed could in theory be trained a process that takes between two and 10 weeks raising the prospect of pet canines joining an army of Covid sniffers. Around the world from the UK to Finland, Spain, Brazil, Lebanon and Australia teams of researchers are training dogs to sniff out Covid-19.
