After the outbreak was announced on Tuesday, 1,200 security workers were sequestered in their rooms.
The number of confirmed cases of norovirus at the Winter Games has risen to 86 from 32 in just two days as Olympic officials struggle to track the source of the outbreak on the eve of the opening ceremony.
The urgent measures are conducted; epidemiologists check water and food supplies for possible contamination. The effects include nausea, vomiting, diarrhea, and stomach pain and cramps. Recovery typically occurs within 1 to 3 days. In some cases, victims also suffer fever, chills, headache, weight loss and fatigue. "The quarantine usually ends in 48 or 72 hours".
As the Winter Olympic Games officially began in South Korea on Friday, a nasty shadow was hanging over the friendly competition and expressions of goodwill - in the form of the highly contagious norovirus.
"The virus can easily contaminate food because it is very tiny and infective". Carefully wash any potentially contaminated laundry; clean toilets, other bathroom surfaces and all kitchen areas with a bleach-based solution.

Overall there are 20 Minnesotans (and one alternate) on Team USA, the third-most after Colorado (31) and California (21). None of this means the intractable issues isolating the North from South - let alone the rest of the world - are solved.
Another frequent prevention strategy is quarantine. The virus can also infect passengers on cruise ships, and people who eat food prepared by a person who is sick with norovirus.
"There is not a whole lot that we can do about it, so we just kind of hope for the best and hope that they are doing as much as they can do to prevent it", an American volunteer said. "It only takes a few viral particles to cause infection, and the virus itself can remain infectious on surfaces for fairly long periods of time", Hochman said. Because Norovirus is viral and not bacterial, it can not be treated with antibiotics.
"There's no confirmed cases and that's the most important thing here, that when the athletes come to [South] Korea they demonstrate their performance after a few years of training", Kim said. And CDC research has found that, of the norovirus outbreaks involving contaminated food, 70 percent are caused by infected food workers.
In order to prevent dehydration, the CDC suggests drinking plenty of fluids, such as water, sports drinks or oral rehydration fluids.
