The Mexican resort of Cozumel welcomed the first arrival of a cruise ship carrying passengers since the coronavirus pandemic essentially collapsed the industry.

Officials in the Caribbean coast state of Quintana Roo welcomed Royal Caribbean's Adventure of the Seas as it arrived from Nassau in the Bahamas at the arrival at the world's busiest stopover for cruise ships.

The cruise line requires all passengers 16 and over to be fully vaccinated. Those who don't have to get Covid-19 tests.

Gov. Carlos Joaquin said about 5% of passengers aboard the ship -- about 150 youths or those with chronic health conditions -- haven't been vaccinated and would be subject to special rules. State and federal health officials were on hand to oversee the arrival.

Mexico has not instituted any testing requirement for incoming passengers, and anecdotal evidence suggests tourists are attracted to Mexico's Caribbean resorts in part because there has been no lockdown and health precautions are largely voluntary. Many visitors shed their masks when they reach their hotels or beach clubs.

The state has seen a recent upsurge in Covid-19 cases, in part linked to increased travel around Easter week, and partial reductions at businesses like hotels and restaurants have been implemented to stem the upsurge.
