The presence of a woman who helped care for an Ebola patient who died has left a Caribbean cruise ship unable to dock at foreign tourist ports and is now heading back to Texas.

One passenger said the announcement of the woman's presence has created "utter panic" on the Carnival Magic cruise ship, while others remained outwardly unfazed, sunbathing by the outdoor pool.

"People are scared,” passenger Jon Malone told ABC News as the ship was waiting miles off shore from Cozumel, Mexico. "I’ve seen people crying.”

The chaos started this morning when there was an announcement on the ship’s intercom saying "that someone who worked in the lab who handled the person in Dallas’s blood was on the ship,” Jon’s brother and fellow passenger Jeremy Malone told ABC. The cruise line said the woman is in isolation on board the ship.

"You're using the same buffet line as someone else, the same waiters, the folks that clean the state rooms. If someone was cleaning their state room and cleaned yours right after, the exposure that you have there to elevators..." he said. "It's very tight quarters and a lot of interaction. It's really difficult to control any type of virus that's on a cruise ship. It's like a floating petri dish. It spreads very rapidly."

The CEO of the cruise ship company is talking to CNN as we speak and he is talking to Richard Quest on how the employee has been isolated from the rest of the ship and that she did not have contact with the patient.
