In an effort to reduce the risk associated with novel coronavirus, the cruise industry's biggest association has proposed new rules that would limit embarkation for vulnerable and elevated-risk passengers. The Cruise Lines International Association (CLIA) has reportedly proposed to deny boarding to any person over the age of 70 unless they present a note from a doctor stating that they are fit to travel on board a cruise ship. Those with an underlying chronic medical condition that would make them more vulnerable to the illness would also be prohibited from embarking. More information: Maritime Executive
