CLEVELAND — Members of the support team for the California delegation to the Republican National Convention have been hit with a norovirus outbreak.

Health officials say about a dozen people are affected by the virus, with symptoms including vomiting and diarrhea.

Pete Schade, health commissioner for Ohio's Erie County, says the individuals are members of the logistics team for the convention delegates.

Schade says none of the delegates appear to have been affected. He says the symptoms were first reported Thursday as logistics members arrived at a hotel about an hour west of Cleveland.

Cynthia Bryant, executive director of the California GOP, told delegation members to wash their hands frequently, avoid shaking hands and not to share food.
