China News Service, December 28. According to the US Chinese website, with the spread of Omi Keron strain, the number of confirmed cases of cruise passengers and crew continues to increase.

The US Centers for Disease Control and Prevention (CDC) said on the 27th local time that the agency is investigating a possible outbreak on 68 cruise ships.

  According to reports, at least four ships were denied calls to foreign ports after cases were found on ships earlier this month.

Last Thursday, after 21 crew members tested positive for the new crown virus, Holland America Line's Line Koningsdam was denied access to Puerto Vallarta.

  According to reports, officials in Jalisco State, where Puerto Vallarta is located, initially planned to allow passengers who tested negative for the virus to disembark, but changed their minds on the grounds that “the number of confirmed cases among the crew has increased exponentially”.

  The ship departed from Santiago on December 19, carrying more than 1,000 passengers and 870 crew, and stopped at Cabo San Lucas and Mazatlan before arriving in Puerto Vallarta.

  A carnival cruise ship was "turned away" on Bonaire and Aruba last Wednesday and Thursday.

Carnival Cruise Line said that "a small percentage" of the 2,497 passengers on board was quarantined after one person was diagnosed.

  Earlier in the same week, Royal Caribbean revealed that 55 vaccinated crew members and passengers on the Ocean Odyssey tested positive for the new crown, and 48 passengers and crew members on the Ocean Symphony tested positive for the new crown.

  Cruise voyages were suspended due to the epidemic, but resumed in June.

According to the CDC, in the first four months of recovery, more than 1,300 confirmed cases were found on the cruise ship.
