The USA's CDC agency (Centers for Disease Control) updated its warning to travelers "to defer all cruise travel worldwide."
The CDC's Level 3 warning was updated on October 21 due to, "widespread ongoing spread of coronavirus disease (COVID-19) has been reported in some countries. Other countries have reported sustained community spread."
The warning comes days before the CDC will announce if its "No Sail" order (banning cruise ships from operations in North America through October 31) will be extended or lifted.
The CDC noted that it typically doesn't post advisories for forms of transportation (airplanes, trains or ships), but because of the unprecedented nature of the coronavirus pandemic, and the increased risk of transmission of on cruise ships, the US Government is advising travelers to defer all cruise travel.
In addition to the warning, the agency recommends anyone with a voyage booked reschedule for a future date.
"As the COVID-19 pandemic continues, there remains a risk of infected passengers and crew on board cruise ships."
