Every cruise ship operating in US with passengers has COVID-19 cases: CDC
COVID-19 cases have been reported on every cruise ship operating in U.S. waters with passengers, according to the U.S. Centers for Disease Control and Prevention.
More than 90 ships are currently being investigated by the CDC or have been investigated and are still being observed by the agency.
In order to meet the threshold for a CDC investigation, a ship must report COVID-19 cases in more than 0.10% of passengers or have a single crew member test positive in the previous seven days.
The only ships in U.S. waters that have not met this criteria, according to the CDC, only have crew members on board.

2022 Grammy Awards postponed due to omicron variant
The 2022 Grammy Awards have been postponed due to the surge in COVID-19 cases linked to the omicron variant.
"After careful consideration and analysis with city and state officials, health and safety experts, the artist community and our many partners, thx have postponed the 64th Annual GRAMMY Awards Show," CBS and the Recording Academy said in a joint statement.
The statement continued, "The health and safety of those in our music community, the live audience, and the hundreds of people who work tirelessly to produce our show remains our top priority. Given the uncertainty surrounding the Omicron variant, holding the show on January 31 simply contains too many risks."
A future date for the Grammys has yet to be announced.
The awards show was scheduled to be held at the Arena in Los Angeles and hosted by "The Daily Show's" Trevor Noah.
This is the second year in a row that the Grammys has been postponed. Last year, the show was held in March after its original date was canceled in January.
