A new stomach flu virus just came to U.S. with more than 140 outbreaks in the country so far, and it's symptoms are very harsh! It is very easily transmittable through air, touching infected people in any way, and can even spread through contaminated objects. So if you touch a pen, or a cup, that's been exposed to the virus, you'll likely get it. There is no vaccine for it yet, and it may take up to 10 years to produce. The best way to protect yourself is to wash your hands a lot and thoroughly.
