( CNN ) The trip was n't so grand for many guests on board Royal Caribbean 's Grandeur of the Seas . The cruise line cut short a nine-day trip to Jamaica and elsewhere by one day after more than 200 people became ill with norovirus and a passenger experienced a medical emergency requiring medical attention on land . The ship returned to the Port of Baltimore on Monday . Gastrointestinal illness sickened 193 guests ( 9.91 % ) and nine crew members ( 1.15 % ) , Royal Caribbean spokeswoman Cynthia Martinez told CNN affiliate WBAL . The U.S. Centers for Disease Control confirmed the `` causative agent '' of the widespread illness was norovirus . The CDC 's Vessel Sanitation Program sent two environmental health officers and two epidemiologists to collect samples on board the ship in Falmouth , Jamaica , the federal agency said . The samples will be tested , and the ship 's response to the outbreak will be evaluated . `` Once all guests had debarked Grandeur of the Seas , we began an extensive and thorough sanitizing onboard the ship and within the cruise terminal , to help prevent any illness from affecting the subsequent sailing , '' Martinez wrote in an email to CNN . `` All guests today will receive a letter at boarding that asks if they have experienced any gastrointestinal symptoms within the last three days , '' Martinez said . `` Similarly , if guests are uncomfortable taking their cruise , for reasons related to personal health or otherwise , our staff assisted them in rescheduling their sailing for another time . The ship will depart today , as scheduled . '' Grandeur of the Seas had two norovirus outbreaks last year , according to the CDC 's Vessel Sanitation Program website . Overall , the CDC reported nine total norovirus outbreaks in 2014 on cruise lines that docked in U.S. ports . Passengers complained about the cruise line not giving them enough information . `` It kind of seemed like they were n't being very honest with us about the whole situation . We heard that there were three people sick . Then another person said it was over 100 , so , I mean , we never got a clear answer from any of the crew members , '' passenger Nick Canning told CNN affiliate WBAL . `` Some people were sick three days , vomiting , diarrhea , and they got shots and medication , and they said it was just a cruise from hell , '' passenger Georgia Moseback said . Passenger April Neall definitely did n't have the honeymoon of her dreams . `` I was happy to leave Baltimore and go to the islands , and now I 'm just happy to be home , '' Neall said . Future cruisers should practice the same hygiene habits at sea that are wise to practice on land to stay healthy , Carolyn Spencer Brown , editor-in-chief of Cruise Critic , wrote in an email . `` Wash your hands frequently and take advantage of the hand-washing stations throughout the ship , '' she said . `` Prior to boarding , passengers go through a health screening aimed to help avoid the possibility of any pre-cruise illnesses being brought onboard -- it 's important for cruisers to answer those questions truthfully to keep themselves , and others , healthy . Other than that , just know that passenger safety is the top priority for cruise lines , and cruise ship staff are well-equipped to prevent the spread of illness onboard as best as possible . ''
Norovirus spread throughout Royal Caribbean passengers and crew . More than 200 people have been sickened on the ship . Score: 6
