123 passengers infected on cruise ship: CDC

The Centers for Disease Control and Prevention (CDC) reported that more than 100 passengers and crew on the Queen Victoria cruise ship had developed a gastrointestinal illness.

The Cunard Cruise Line ship departed on January 22 and is scheduled to return on February 12. The Centers for Disease Control and Prevention's Vessel Sanitation Program (VSP) said.

Of the ship's total 1,824 passengers, 123 reported contracting the disease during the voyage. Of the 967 crew members, 16 people became ill. The cases are for the entire trip so far and do not represent the number of active cases.

The cause of the disease is unknown, but symptoms include diarrhea and vomiting.

According to the CDC, the cruise line and its crew reported increased cleaning and disinfection procedures that are consistent with the ship's outbreak prevention and response plan. Sick passengers and cabin crew are isolated.

“VSP is monitoring the situation remotely, including reviewing the ship’s response to the outbreak and sanitation procedures,” the notice said.

According to ABC News, the flight left Fort Lauderdale, Florida, and is scheduled to go to San Francisco before ending in Honolulu.

“Cunard confirms that a small number of guests reported symptoms of gastrointestinal illness on board Queen Victoria. They immediately activated enhanced health and safety protocols to ensure the safety of all guests and crew on board,” the company said in an email statement.

The company said that the measures taken so far have been effective.
