Louisiana is on track to break previous whooping cough case record


Louisiana is facing a record-breaking surge of whooping cough cases and is on track to surpass the highest number of reported cases in decades, state health officials said Wednesday.

The state has data on whooping cough, also known as pertussis, going back to the 1990s, said Teresa Sokol, state epidemiologist at the Department of Health. Previously, the highest case count was 214 cases in 2013.

“Our current trajectory with whooping cough cases this year means that we are unfortunately on track to surpass that number of cases, probably before the end of this year,” Sokol said.

During a press conference that incoming LDH Secretary Bruce Greenstein said was about transparency and protecting the public’s health, officials shared updates on both the measles and whooping cough outbreaks. While the state has successfully contained measles, whooping cough cases continue to rise, posing a significant risk to infants too young to be fully vaccinated.

Whooping cough cases rise

As of Wednesday, the state reported 170 whooping cough cases in 2025, surpassing the total of 153 cases recorded in all of last year. Since September 2024, the outbreak has led to 42 hospitalizations, with nearly 70% involving infants under one year old. Two infants have died, marking the first fatalities in Louisiana since 2018.

Newborns are especially vulnerable to whooping cough because they have immature immune systems, said Dr. Margot Anderson, a pediatric infectious disease expert at Tulane University. In older kids, the virus is usually an “annoyance,” but its lengthy contagious period makes it easy to spread.

“We used to call it the 100-day cough,” said Anderson. “They’re contagious for at least three weeks of coughing.”

Infants get their first pertussis vaccine at 2 months. To protect them, Anderson recommended what’s known as “cocooning” – keeping infants away from others until they get their first shot. She also recommended a booster shot during pregnancy to give the baby antibodies.

Five of the 42 hospitalized pertussis patients were vaccinated. Six had an unknown vaccination rate, and the remaining 31 were undervaccinated or unvaccinated.

One in three babies under the age of one who get whooping cough will be hospitalized, said Sokol.

“The younger the baby is, the more likely they’re going to have a severe illness,” she said.

Anyone who is going to be around the infant in early days, such as grandparents or siblings, should be up to date on the pertussis vaccine, which is given as part of the DTaP vaccine for children and the Tdap vaccine for adolescents and adults. Those vaccinecs also protect against diphtheria and tetanus.

It’s likely that whooping cough is going undetected in the state due to less frequent testing, said Sokol. Though Louisiana’s overall case rate for pertussis is lower than the national average, the rate of severe cases requiring hospitalization is significantly higher, at 15% compared to a national average of 5%.

Surgeon General Dr. Ralph Abraham said Louisiana residents should consult health care providers if there are any concerns about a child’s health. He advised parents to seek medical attention if a child has symptoms like high fever, not eating, not drinking, or decreased urinary output.

“I would recommend talking to your health care provider if you have questions about your immunity to these diseases, because there are tests we can do to check your immunity,” Abraham said.

For those who do not have a regular health provider, Abraham recommended visiting a parish health unit.

Measles cases closed

On May 9, Louisiana closed the investigation that stemmed from a travel-related measles case in the New Orleans area in mid-April. One additional case was found through contact tracing, but that case was already past the incubation period when it was identified. According to Dr. Pete Croughan, 75 people were exposed, about half of whom were health care workers.

Two high-risk contacts received post-exposure drugs that are typically given to people who are unvaccinated, “which almost certainly prevented additional cases,” Croughan said.

These cases coincide with a national uptick, with over 1,000 confirmed measles cases across 31 states by early May, the highest annual total since 2019.

Approximately 96% of these cases have occurred in unvaccinated or under-vaccinated individuals, according to the Centers for Disease Control and Prevention.

Some parents have asked about giving their children an early measles vaccine before the typical timeline of one year. Anderson advised that since there is no evidence of active spread of measles within the state, early vaccination is generally not necessary, except in cases where a child may travel to areas with ongoing outbreaks.

Recent state policy changes have reduced proactive vaccine promotion, ending mass vaccination events like flu shot fairs and instructing public health employees to direct residents to their health care providers rather than actively recommending vaccines.

Abraham said he would not consider holding vaccine events for pertussis, but said the department was promoting the vaccine on its website, urging residents to speak with their physicians.

Access is a problem Anderson often sees in hospitalized patients with vaccine-preventable diseases.

“We were so interested in this problem of vaccine refusers or skeptics, but oftentimes it’s that they live in Tickfaw, or somewhere really rural, and don’t have transportation,” she said.

Louisiana’s disappearing coast could shape Baton Rouge’s future

Louisiana’s disappearing coast could shape Baton Rouge’s future


BATON ROUGE, La. (WAFB) – South Louisiana’s coast has long served as a natural buffer between communities and rising water.

But since the 1930s, Louisiana has lost nearly 2,000 square miles of coastal land.

Dr. Torbjorn Tornqvist, a professor at Tulane University, said Louisiana is one of the most vulnerable coastal areas in the world because of climate change, sea level rise and subsidence.

“Louisiana is arguably one of the most vulnerable… perhaps the most vulnerable coastal zones in the world when it comes to climate change and sea level rise… and there are several reasons for that but one important reason is that we have high subsidence rates, and that means sea level rise here is a lot faster than the average around the world,” Tornqvist said.

Tornqvist is the lead author of a recently published study examining the long-term impacts of sea level rise across south Louisiana.

He said the issue is no longer limited to communities closest to the Gulf Coast.

“People are leaving the coast of Louisiana, but it’s going to accelerate over the course of the century. And those people are going to have to go somewhere, and it’s likely that a significant number are going to look at a place like Baton Rouge to move to,” Tornqvist said.

Since Hurricane Katrina, Louisiana has invested billions of dollars in large-scale restoration projects designed to reduce flood risk and strengthen the coast.

Some researchers believe those projects are important but not permanent fixes.

“We have…right now we have a pretty high-quality flood protection system that’s obviously way better than it was during Katrina and we should certainly keep investing in upkeep, but we also have to recognize that’s only going to take us so far,” Tornqvist said.

State officials say those investments remain critical as Louisiana adapts to future flood risks.

Micheal Hare, executive director of the Coastal Protection and Restoration Authority, said the state’s coastal plan is designed to balance restoration work with protection projects, including levees.

“Our 2023 master plan certainly incorporates the best science available to us to then come up with a balanced approach between how do we effectively spend money on restoration as well as money on protection projects like levees,” Hare said.

Hare said those projects will continue to evolve as future risks change. CPRA and the Army Corps of Engineers are re-evaluating portions of the West Bank and Vicinity levee system in New Orleans to meet projected future flood risks within the next half-decade.

“Morganza to the Gulf is a great example, location communities came together, they started funding it…so that protection is critical…It will constantly be maintained and constantly elevated to meet the new levels of threats and risks that are out there,” Hare said.

Coastal officials and researchers agree that what happens along Louisiana’s coast will continue to affect communities far beyond the shoreline for generations.

“And so maybe you don’t live behind the levee, but I promise you want those coastal communities to stay there and to keep working, and to stay productive and engaged…so that we don’t have to have these flood fights further north or lose parts of our economy,” Hare said.

Tornqvist said the decisions made now could shape the future of Louisiana communities.

“What’s really important to recognize is that the next few decades are basically going to decide the long-term future of cities like Baton Rouge,” Tornqvist said.

Louisiana has always lived with water. As the coast changes and sea levels rise, the challenge is how communities across south Louisiana continue adapting for generations to come.

From the Gulf Coast to Baton Rouge, the future of Louisiana’s coastline is a conversation that impacts the entire state.

Louisiana is the eighth most affordable state to retire, study says




Louisiana ranks among the top 10 most affordable states to retire, according to a new study from Retirement Living, a national journal of retirement research.

Researchers analyzed each state’s housing costs, living expenses and tax friendliness to compile the ranking. Louisiana, they say, is the eighth most affordable state for retirees.

In Louisiana, the median monthly rent for a one-bedroom apartment is $932, the median home sale price is $255,000, monthly grocery spend per capita is $272, the average price per gallon of regular gas is $4, the average Medicare Advantage monthly premium is $13.35 and the average effective property tax rate is 0.55%.

Louisiana agencies urge hurricane preparation ahead of season start


BATON ROUGE, La. (WAFB) – With hurricane season approaching, the Louisiana Coastal Protection and Restoration Authority is bringing the community together to prepare before a storm forms.

“We can’t stop disasters from happening. We can’t stop hurricanes from happening. But what we can do is equip our communities with the resources that they need to prepare for these storms ahead of time,” said Jayda Morris, CPRA outreach manager.

The agency hosted an event featuring interactive storm simulations and a full model of the Mississippi River.

“If you do it now, like on a sunny day like today, you’re ready to go for the rest of the season,” Jay Grymes said.

El Niño may reduce storms, but Louisiana still at risk

State Climatologist Jay Grymes said an El Niño pattern may reduce the number of storms in the Atlantic but warned against a false sense of security.

“In those 25 years, Louisiana, some part of the state has been impacted by 29 storms. That’s one a year, regardless of El Niño. So that should tell you something,” Grymes said.

He said the bigger concern is storms that can form in the Gulf with little warning.

“If we’re going to get a storm, it very possibly could be one that bubbles up in the Gulf and doesn’t give us five or seven days to track it coming our way. It gives us 40 hours to get ready for a landfall. So it’s imperative that you go ahead and do it now,” Grymes said.

Preparation goes beyond stocking water

Preparing now includes walking through yards, checking trees, and knowing whether everyone in the family can survive two weeks without power.

PhD students with the LSU College of the Coast and Environment gave the community a virtual reality experience that puts users inside a storm.

“If they wear the goggles or play with the Apple Vision Pro, they can understand how high will the flood be, and they can know how dangerous is the hurricane scenario,” said Yixuan Wang.

The VR simulation uses real historical data to show users what compound flooding looks like in New Orleans and surrounding areas. The goal is to make the science real for people who can’t picture what a flood map means.

“It’s just to let you understand the environment. We will add the audios, the different sound of the wind and the storm. And you can see how tense of the rainfall around you,” Wang said.

Organizers said the event is about making sure that when a storm threatens the area, families already know their plan.

Information from the event is available on CPRA’s website. Hurricane season runs through Nov. 30.
