Carnival tightens Covid policies 
Carvinal Cruise Line is requiring all passengers to wear masks in some indoor areas and get tested for Covid before their trip. From August 7, passengers have to wear masks in areas like the lifts and casino. Beginning August 14, both vaccinated and unvaccinated guests will have to show proof of a negative COVID-19 PCR or antigen test taken within 72 hours of the start of their cruise.  

“These new requirements are being implemented to protect our guests and crew while onboard, and to continue to provide confidence to our home ports and destinations that we are doing our part to support their efforts to protect public health and safety," Christine Duffy, the president of Carnival Cruise Line, said in a statement.  

The change comes after a "small number of positive cases" of Covid-19 were detected aboard the company’s Carnival Vista ship, CNN reported. 

In line with other cruise companies 
Carnival is currently operating a series of cruises in which 95% of its passengers and crew must be vaccinated. The company exempts children under 12 and some adults from the requirement. Those who want an exemption must apply online.  

The new rule comes after the U.S. Centers for Disease Control and Prevention urged all Americans to wear masks indoors in areas at risk of high coronavirus transmission. Other cruise companies  have also adopted strict measures to reduce the spread of new Covid variants. Royal Caribbean requires all guests to get tested for COVID-19 for specific cruises. Cunard and Fred. Olsen require face masks indoors but not outside. For people who travel with MSC Cruises, the face-covering rule also applies in public areas.
