The Utah Department of Health says dozens of people attending business conferences in Park City were confirmed to have contracted Norovirus, a sickness that causes flu-like symptoms.

Officials say people attending two separate business conferences came down with the sickness. They believe the outbreak is over, but they still want everyone to be careful and report suspected cases.

Summit County health officials say the most common place to get the Norovirus is where large groups of people gather. It is often seen occurring on cruise ships. In Park City it occurred at two large business gathering where people ate catered food.
