Right now there are dozens and dozens of infected people walking around infecting other people, visiting shops and restaurants, touching their faces, then touching handles, faucets, items, silverware, etc. They don't know they have it and might not even start showing signs for two weeks. Until then, they're unaware they're passing it around. There are dozens more infected people right now flying on airplanes where they're likely infecting the entire planeload of people, flying in and out of countries, then they all disperse upon landing. Only a matter of time before it spreads like wildfire in our big cities. It's looking increasingly likely this a lab strain and not from 'bat soup', too.
