Dozens of Passengers Sailing from Baltimore Fall Ill on Cruise Ship

For the second time in two trips, dozens of passengers sailing from the Port of Baltimore have become sick on a cruise ship.

The passengers boarded Royal Caribbean's Grendeur of the Seas on April 5 for a seven-day cruise to the Bahamas, WTOP reports.

Royal Caribbean spokeswoman Cynthia Martinez told The Associated Press that passengers were responding well to over-the-counter medication being administered on the ship.

The Centers for Disease Control and Prevention said on its website that about 100 passengers and crew members fell ill with vomiting and diarrhea. Martinez said a norovirus was believed to be the cause.

The CDC said more than 100 passengers and crew members got sick on the Grandeur's last cruise from Baltimore from March 28 to April 5. The agency said the cause was a norovirus.
