(Updated 6:27 p.m. ET) -- Virtually all of the world's ocean and river cruise lines have suspended global operations due to the COVID-19 pandemic and travel restrictions around the world, in many cases even extending the dates of suspension before the original timeline ran out.

The shutdowns, which come after two months of altered itineraries, canceled cruises and port closures, are part of the cruise industry's efforts to curb the spread of coronavirus and to keep passengers, crew and communities safe and healthy,
