Louisiana whooping cough cases for 2025 higher than last year's total, LDH reports
BATON ROUGE, La. (Louisiana First) — Louisiana's health department reports an increase in whooping cough cases that could lead to a record high this year.
Compared to 153 total state cases in 2024, the Louisiana Department of Health (LDH) has identified 164 cases in the first four months of 2025. Nationwide, over 8,400 cases have been reported this year by the U.S. Centers for Disease Control and Prevention.
LDH reported that 40 people have been hospitalized with whooping cough, or pertussis, since September 2024, with 70% of those being babies younger than 1 year old. Two babies in Louisiana have reportedly died with the rise in cases.
Experts said whooping cough peaks every two to five years, occurring around this time of the year and in the fall. State Epidemiologist Theresa Sokol described the surge in cases as a 'return' to disease activity patterns before the COVID-19 pandemic.
'What I can tell you is that we had a very low number of cases during the pandemic because people were practicing mitigation measures that decrease the spread of respiratory diseases,' Sokol told Louisiana First News.
Sokol said symptoms can appear like a common cold before coughing fits possibly develop one to two weeks later. She said coughing 'can be so strong that people make a high-pitched whoop.'
Babies are at a greater risk of whooping cough complications and death. Health officials said the bacteria that cause the disease are often unknowingly spread to babies by family members or caregivers. Sokol said babies' symptoms can differ from adults, showing as apnea and causing them to turn blue and struggle to breathe.
Vaccines for pregnant women and people, including children and teens, in close contact with babies are recommended. Sokol said the department recommends people review their immunization histories and talk to health care providers about the pertussis vaccine.
'We feel like this is especially important now because of the increased pertussis activity that we've been seeing recently in Louisiana,' Sokol said.

Activists protest possible Medicaid cuts outside KS Rep. Derek Schmidt's Topeka office
TOPEKA (KSNT) — Kansans are speaking out against lawmakers who are voting to cut Medicaid. The GOP-led One Big Beautiful Bill Act passed the US House by a razor thin margin. 215 House members voted to pass it, while 214 voted against it. Local Kansas activists are calling out Rep. Derek Schmidt, a Republican who voted to pass the bill. A group of protesters gathered outside of Schmidt's office in Topeka Thursday afternoon and expressed concerns about cuts to Medicaid. 'Today is life or death,' protester Dillon Warren said. 'We voted someone in there that we shouldn't have. He doesn't support us.' The Congressional Budget Office estimates that if the bill passes, at least 7 million people will lose Medicaid coverage. For that reason, many Kansas voters are making their voices heard. Chiefs and Royals stadium bill deadline approaching as Kansas and Missouri fight for the teams 'We need Medicaid for medical equipment,' protester Rick Macias said. 'These chairs are $200,000 if not more. So, it's very important that Medicaid sticks around.' 27 News reached out to Schmidt, who was unavailable for comment. A spokesperson for the congressman provided 27 News with a written statement. 'Congressman Schmidt is a strong supporter of Medicaid for people the program is designed to help: those who are disabled, in nursing homes, pregnant, raising small children, or otherwise in need. Unfortunately, some states have abused the program by providing benefits to illegal aliens, millions of healthy young adults who choose not to work, or people who are not eligible to receive taxpayer-funded benefits from the program. That is the main reason why Medicaid spending has exploded by more than 50 percent since just 2019: an unsustainable rate of growth that puts benefits for Americans who need them most at risk. By addressing this abuse of the program, Congressman Schmidt is protecting both the traditional Medicaid recipients who rely on benefits and the taxpayers who pay the bills.' Spokesman for Rep.

Migratory birds develop antibodies to bird flu, officials say
(WAVY) – Wildlife officials are keeping a close eye on the spread of avian influenza after along the North Carolina coast earlier this year — most of them brown pelicans. The outbreak has since been linked to the H5N1 strain of bird flu, a virus that continues to mutate and occasionally jump to other species, raising concern among experts. Miranda Turner, a wildlife health biologist with the North Carolina Wildlife Resources Commission, said the area is a prime wintering ground for birds — making it easier for disease to spread. 'When you bring a lot of animals together and you have them traveling from different locations, it's a really good way to transmit diseases,' Turner said. In Hampton Roads, bird flu outbreaks aren't new. Lisa Barlow, president of T recalls treating sick and dying Canada geese during a 2021 outbreak on the Lafayette River. 'We dealt with about three to four dozen Canada geese that came in sick and dying,' Barlow said. 'Only six survived the flu, and even those had to be euthanized due to severe neurological symptoms.' Barlow described birds arriving unable to hold their heads up, their beaks caked in mud. Many died within 24 hours. As the virus continues to affect wildlife, it's not just birds at risk. , including seals, cats and even cattle. Experts say it's mutated at least several times since it was first identified. 'I mean, anything that can do that — it's kind of frightening, but amazing,' Barlow said. Despite the concerning spread, health officials emphasize the risk to humans remains low. According to the Centers for Disease Control and Prevention, 70 human cases have been reported nationwide, including one death. Most infections have been among people with repeated exposure to infected animals, such as poultry or dairy farm workers. 'There's really low risk,' Turner said. 'Still, it's a good idea to clean bird feeders regularly and wear gloves or a mask if you handle injured wildlife.' Barlow also urges caution for those who come across sick birds. 'If you do want to help, wear gloves, protect yourself,' she said. 'Common sense goes a long way.' Meanwhile, as migratory birds continue to interact and spread the virus, some are developing natural antibodies, according to Turner. 'They're bouncing back and creating herd immunity,' she said. Last week, the Associated Press reported the in funding meant to support Moderna's development of a bird flu vaccine. The vaccine, which uses mRNA technology similar to the COVID-19 vaccine, had shown early promise in clinical trials. For now, wildlife officials say they expect to see more outbreaks in the years ahead, especially during peak migration periods. 'Because this virus is so common in migratory birds, it is likely that we will continue to see cases here and there every winter,' Turner said. As of right now, there have been no confirmed human cases of H5N1 in Virginia and although the risk remains low for humans, for birds it can be extremely deadly – leading to large die-off events like the ones we saw near Cape Hatteras. 'Unfortunately, this was the first kind of major large scale mortality event… while it looks really bad at that small scale of seeing 300 brown pelicans die – it's not impacting their population as a whole or the species as a whole,' adds Turner. Turner also explains that the surviving pelicans are still there, 'The brown pelicans that did survive that event were still nesting on that island successfully and are doing well. So really, it's a short scale kind of scary looking event, but nothing that raises alarm for biologists in the long term.' Copyright 2025 Nexstar Media, Inc. All rights reserved.

New coronavirus discovered in China ‘only small step' from infecting humans
A new coronavirus discovered in China is only a small step from mutating and causing another global pandemic, experts have warned. Scientists believe the variant, called HKU5-CoV-2, may infect a broader range of animals than Covid-19 – which caused millions of deaths – and may have more potential for jumping between species. US researchers fear that HKU5-CoV-2, found in China, in February, could also infect humans, leading to a widespread outbreak. The new study, published in Nature Communications, looked at a lesser-known group of coronaviruses called merbecoviruses, which includes HKU5 and MERS-CoV, which is responsible for the deadly Middle East Respiratory Syndrome. The team from Washington State University looked at how the new pathogen interacts with human cells. They found that a small change in the virus's spike protein could allow it to attach to human ACE2 cells in people's throats, mouths and noses. HKU5-CoV-2 can infect and replicate inside human cells in both the airways and gut. According to the World Health Organisation, about 35 per cent of people infected with Middle East Respiratory Syndrome die. Since 2012, some 27 countries have reported cases, leading to 858 known deaths due to the infection, which spread from camels. But when HKU5 was discovered in February, scientists warned against exaggerating the risks because it does not enter human cells as readily as Sars-CoV-2, which caused Covid-19. HKU5 was first detected in bats by scientists from the Chinese laboratory where some say Covid originated in 2019. Prof Michael Letko, a virologist who co-led the study, said: 'HKU5 viruses in particular really hadn't been looked at much, but our study shows how these viruses infect cells. 'What we also found is HKU5 viruses may be only a small step away from being able to spill over into humans.' When Covid-19 emerged it was widely blamed on markets in China where different breeds of wild animal are kept caged and often slaughtered close to other animals. Meat is sold at the open-air stalls. Critics said the markets were the perfect breeding ground for new zoonotic diseases – those that spread to humans – to emerge. The scientists, whose experiments studied how the new pathogen interacts with human cells, believe the virus would have to carry certain mutations if it were to infect humans. 'These viruses are closely related to MERS, so we have to be concerned if they ever infect humans,' Prof Letko said. 'While there's no evidence they've crossed into people yet, the potential is there and that makes them worth watching.'
