Outbreaks of infectious diseases can happen on cruise ships because people spend time close together and with travelers from many countries. Disease can spread between ships when crew members from a ship with an outbreak transfer to other ships. Infected people may also travel on cruise ships between countries. For these reasons, outbreaks of COVID-19 on cruise ships pose a risk for rapid spread of disease beyond the voyage and into communities across the globe. Because of the unprecedented nature of the COVID-19 pandemic and the high risk of COVID-19 spread on cruise ships, the US government issued a No Sail Order for cruise ships in waters subject to US jurisdiction and has advised US travelers to defer all cruise travel. The No Sail Order is published in the Federal Register. CDC continues to work to control COVID-19 on cruise ships at sea while also protecting against further introduction and spread of COVID-19 into communities. The COVID-19 pandemic is constantly evolving, and aggressive efforts are needed to contain the spread. CDC will continue to evaluate and update our recommendations as the situation evolves.
