The United States Centers for Disease Control and Prevention C-D-C, said people should avoid traveling on cruise ships regardless of their vaccination status.

This as daily Covid-19 cases continue to climb to record highs, due to the fast-spreading Omicron variant.

According to Reuters, the move delivers another blow to the cruise industry that had just started returning to the seas in June, after a long suspension of voyages, due to the pandemic.

Earlier today (December 30), the CDC raised its Covid-19 travel health notice for cruise ships, to its highest warning level, citing reports of Covid-19 outbreaks on cruises.
