Earlier in the Olympics, about 1,200 security workers were sequestered over norovirus fears, forcing the military to step in to help with security.
Norovirus is a common, infectious bug that causes symptoms including diarrhea and vomiting but doesn't require medical treatment.
There are signs all over the Olympics reminding people to wash their hands and use hand sanitizer.
