The captain of the cruise ship “MSC Opera,” which is set to arrive at the Greek island of Corfu on Thursday, has reportedly told more than 2,000 passengers not to leave the vessel, due to the diagnosis of a covid19 coronavirus case on board. One of the previous vacationers who were on board the ship was tested and found positive for the Covid19 coronavirus. Passengers from the ship were in Athens on Wednesday, but they were summoned and told to return to the vessel as soon as possible after the discovery, due to “security reasons.” The tourists were informed about the positive case of one of the passengers, who is not onboard any longer.
