After arriving back to Charleston with more than 400 sick passengers struck with a norovirus, the Celebrity Mercury sailed back out on February 27 with 1,900 new passengers. Since then, 55 passengers have fallen ill.
The Post and Courier reports the illness seems to be another stomach bug. This specific cruise voyage was delayed for one day so crew members could make sure the ship was fully sanitized before any new passengers boarded.
The Centers for Disease Control and Prevention said the symptoms of the passengers on the last voyage were nausea, vomiting, diarrhea, and stomach cramps.
