This strategy includes screening guests and crew before they board a ship, surveillance of any illnesses that may arise on a cruise, constant sanitation of public areas, effective communication with guests and crew in the event of an outbreak of illness, isolation and treatment of any ill guests or crew members, electronic reporting systems that enable us to effectively track data on illnesses and report them to the relevant authorities, and appropriate disembarkation of any guest or crewmember who requires hospitalization or medical treatment that cannot be provided onboard the ship.
