South Korean Olympic organizers quarantined more than 1000 workers after some tested positive for the norovirus,a stomach bug that causes nausea, vomiting and diarrhea.Norovirus is a virus that’s exceptionally contagious, it can be spread by simply touching surfaces.And it can survive for days or even weeks on a variety of surfaces, it only takes a small amount of the virus to infect someone.
It can be spread by vomiting and because it can aerosolize to some extent, people can pick up enough that way,it can be spread through the stool if you accidentally get a little bit of feces on something.
The virus spreads quickly between people especially in close quarters like cruise ships and nursing homes, it can spread wherever there are crowds.The norovirus can also be passed on through contaminated food and water if the person handling it has the virus or gets fecal matter on the food or in a drink.
Symptoms normally last for a few days but afterwards it causes fatigue, the antidote is cleanliness.Lots of hand washing and disinfecting any surfaces that might be contaminated especially kitchens and bathrooms and keeping your fingers away from your face. If all goes well, the athletes can just focus on their sports.
