Cruise ship returns with more than 100 sick passengers

A Holland America cruise ship returned Monday from a 10-day trip to Mexico with at least 104 passengers and six crew members who had suffered from a gastrointestinal illness. The passengers and crew members are believed to have come down with norovirus, which can produce nausea, vomiting and diarrhea and lasts about 24 to 48 hours, said Holland America Line spokesman Erik Elvejord.
