Carnival Cruise Line plans to make masks optional for its guests from March 1 after the U.S. Centers for Disease Control and Prevention (CDC) eased its warnings for cruise ships, the company said in a statement late on Friday.

The company said masks would be recommended but not required. It plans to offer more flexibility in pre-cruise testing requirements.

Children that are 5 years and younger will be allowed to sail without any need for vaccine or exemption.

The easing of the mask mandate follows similar action from cruise operator Norwegian Cruise Line Holdings Ltd and theme park Disney World. 

The U.S. CDC eased its warnings for cruise ships by a notch from the highest level two days earlier in response to a decline in onboard COVID-19 cases.
