Wayne County health officials confirmed today that the outbreak of vomiting and diarrhea that sent nearly 100 people to area hospitals Sunday from a hockey tournament at the Taylor Sportsplex was caused by a fast-spreading norovirus.

The Detroit Free Press reports the Sportsplex reopened Thursday, and "the majority of individuals who suffered norovirus symptoms have recovered or have nearly recovered — they’re showing the classic progression of the virus running its course." Wayne County Department of Health spokeswoman Mary Mazur said.

The city-owned building was shut down Sunday night so that water and air testing could be performed, and the entire building has been disinfected, Mazur said Friday. It had been scheduled to reopen Wednesday, but managers of the facilities "decided to err on the side of caution" and gave an additional day to the clean-up and testing, she said.
