Some passengers sick on another cruise out of Charleston

CHARLESTON, S.C. (AP) — Some passengers have come down with a stomach bug aboard a cruise ship that was hit by a virus on its previous trip last month.

Celebrity Cruise spokeswoman Cynthia Martinez says 55 of the nearly 1,900 passengers on board the Celebrity Mercury have fallen ill.

More than 400 passengers and crew got sick during a cruise that ended in Charleston, S.C. on Feb. 26. The vessel sailed again last weekend after a one-day delay to allow a crew to sanitize the ship.

The Centers for Disease Control and Prevention said tests showed last month's outbreak was caused by norovirus, which can spread quickly in closed quarters. Symptoms include nausea, vomiting, diarrhea and stomach cramps.

The CDC Vessel Sanitation Web site lists three other ships scheduled to return from cruises today with reports of intestinal illnesses. They are the Celebrity Cruise Millennium sailing from Puerto Rico, the Royal Caribbean International Jewel of the Seas on a cruise out of Miami and the Holland American Line Maasdam out of Fort Lauderdale.
