The state of Louisiana has decided to end its indoor mask mandate after emerging from its latest and worst coronavirus spike of the pandemic, authorities said on Tuesday.

Louisiana has seen a sharp decline in new COVID-19 infections, Governor John Bel Edwards said. The decision marks one of the first mask mandates enacted for the delta variant-fueled outbreak to be scrapped.

“I stand here today optimistic, relieved that the worst of the fourth surge is very clearly behind us now,” Governor Edwards said, according to Associated Press.

The state will still have some face-covering rules in place for Louisiana’s K-12 schools. Edwards said children have greater exposure risks, with students under 12 unable to yet get vaccinated against the coronavirus.

School districts that maintain tight quarantine regulations for students who come into close contact with someone who tests positive for COVID-19 won’t be required to have a mask mandate. Those districts that don’t require all exposed students to be sent home will have to keep students masked up.

The new regulations take effect on Wednesday.

Despite the governor’s decision, Louisiana State University said it will keep its indoor mask mandate through the end of the semester. New Orleans also indicated it won’t necessarily follow Edwards’ lead.

Edwards reinstated the mask mandate in August when Louisiana had the nation’s highest per capita COVID-19 infection growth and hospitals were inundated.

Since then, new cases and hospitalizations have fallen dramatically, and Louisiana now has one of the nation’s lowest rates of new infections.

Still, Louisiana continues to have one of the lowest coronavirus immunization rates in the country — with only 47% of the state’s population fully vaccinated.

“We will remain vulnerable in Louisiana to another surge until we can get more of our friends, family, and neighbors vaccinated,” said Dr. Joe Kanter, the governor’s chief public health adviser.
