Cruise Ship Horror: 150+ Passengers Infected with Virus.

A norovirus outbreak on a Celebrity Cruises ship in May left 152 passengers and 25 staff members sick, according to a CDC investigation. This is one of 12 notable instances of gastrointestinal illness on international cruise ships reported by the CDC so far this year, which is significantly higher than in previous years. The predominant symptoms were diarrhea, vomiting, abdominal cramps, and headache. Norovirus can be especially challenging to control on cruise ships because of the close living quarters, shared dining areas, and rapid turnover of passengers.
