Royal Caribbean on Friday barred all travelers holding Chinese, Hong Kong or Macau passports from boarding its ships due to concerns over coronavirus.

The ban applies to anyone holding one of those three types of passports regardless of when the person was last in their home regions, the company said in a statement.

Additionally, regardless of nationality, any guest or crew member who has traveled to mainland China, Hong Kong or Macau, or been in contact with someone who has, less than 15 days before boarding won't be allowed to board the company's ships.
