Starting Monday, France's residents and visitors must show a "Pass Sanitaire" -- or COVID health pass -- that gives the individual's vaccination status or negative test result. The pass is needed for long-distance travel by plane or train and to get into businesses including restaurants, malls and retirement homes.

The passes can be digital or in paper form. It's not required for kids under 12, but after Aug. 30, it will be required for those children ages 12 to 17.

In hard-hit Louisiana, where the positivity rate is about 15%, Gov. John Bel Edwards told "GMA 3"there's no indication the state has reached the peak of this surge.

Louisiana has more than 2,700 COVID-19 patients in hospitals, the governor said, noting that during the previous surge's peak, hospitalizations only reached 2,100.

"We are having the worst situation in terms of the pandemic across the board here in Louisiana. And unfortunately, we don't see anything that indicates that we have peaked," he said. "Cases continue to go up, hospitalizations, and 20% of new infections over the past couple of weeks have been in children under 18."

The governor has reinstated a mask mandate for August as cases skyrocket.

Edwards noted that "the two sectors of the economy hit hardest by COVID related to oil and gas because the demand fell so much for those products, and then to tourism because people stopped traveling."

"This is a very serious blow. But we believe and hope that this is going to be a relatively temporary change, not unlike the one that we had last March, and that sometime over the next several weeks, we will get past this surge and then continue to get people vaccinated and that the confidence will increase," he said.

The proportion of hospitalized COVID-19 cases among vaccinated people has risen sharply since spring, coinciding with the sudden rise of the delta variant, according to the CDC's internal briefing slides reviewed by ABC News.

The finding doesn’t mean the vaccines aren’t working. People are still considerably less likely to wind up in the hospital or die if they are vaccinated, health officials have said.

The reality of more breakthrough cases also could be tied to the larger number of Americans getting vaccinated. While breakthrough cases remain relatively uncommon, the more people in the U.S. who are vaccinated increases the chances for breakthrough cases to be counted.

According to the CDC, vaccinated individuals who end up hospitalized tend to be elderly, medically vulnerable or live in long-term care facilities. They also are more likely to be asymptomatic and are hospitalized for reasons other than COVID-19.

On July 17, CDC Director Rochelle Walensky estimated that 97% of hospitalizations were occurring among people who weren’t immunized.
