The United States is facing a COVID-19 surge this summer as the more contagious delta variant spreads.

More than 613,000 Americans have died from COVID-19 and over 4.2 million people have died worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.

Just 57.9% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.

The CDC on Tuesday, citing new science on the transmissibility of the delta variant, changed its mask guidance to now recommend everyone in areas with substantial or high levels of transmission -- vaccinated or not -- wear a face covering in public, indoor settings.

Delta variant leaves vaccinated, unvaccinated with similarly high viral loads: CDC 

Data shows that the delta variant leaves vaccinated and unvaccinated people with similarly high viral loads, CDC Director Dr. Rochelle Walensky said in a statement Friday.

"High viral loads suggest an increased risk of transmission and raised concern that, unlike with other variants, vaccinated people infected with Delta can transmit the virus," Walensky said. 

"This finding is concerning and was a pivotal discovery leading to CDC’s updated mask recommendation" this week, Walensky said.

Florida gov. says parents can decide if their kids wear masks in school

Florida Gov. Ron DeSantis said Friday that parents in the state can decide if their children will wear masks in school, despite the Centers for Disease Control and Prevention’s recommendation this week that students wear masks.

DeSantis called the CDC’s guidance a "callous disregard for the physical, emotional and academic well-being of our children."

DeSantis said, "Very soon I'll be signing an executive order which directs the Florida Department of Education and the Department of Health to issue emergency rules protecting the rights of parents to make this decision about wearing masks for their children."

The governor added that his children will not wear masks in school.

Four of the passengers -- who were not traveling together -- are vaccinated. The other two are unvaccinated minors who were traveling together, the cruise line said.

One person has mild symptoms. The other five have no symptoms, the cruise line said.

"The guests were immediately quarantined, and their immediate travel party and all close contacts were traced and all tested negative," Royal Caribbean said. "Each guest and their immediate travel parties disembarked in Freeport, The Bahamas, and separately traveled home via private transportation."

This cruise started in the Bahamas on July 25. Everyone over 16 must be fully vaccinated and test negative before boarding, the cruise line said.
