Texas measles outbreak nears 100 cases, raising concerns about undetected spread
Some private schools have shut down because of a rapidly escalating measles outbreak in West Texas. Local health departments are overstretched, pausing other important work as they race to limit the spread of this highly contagious virus.
Since the outbreak emerged three weeks ago, the Texas health department has confirmed 90 cases with at least 16 hospitalizations, as of Feb. 21. Most of those infected are under age 18. Officials suspect that nine additional measles cases reported in New Mexico, across the border from the epicenter of the Texas outbreak in Gaines, are linked to the Texas outbreak. Ongoing investigations seek to confirm that connection.
Health officials worry they're missing cases. Undetected infections bode poorly for communities because doctors and health officials can't contain transmission if they can't identify who is infected.
"This is the tip of the iceberg," said Rekha Lakshmanan, chief strategy officer for The Immunization Partnership in Houston, a nonprofit that advocates for vaccine access. "I think this is going to get a lot worse before it gets better."
An unknown number of parents may not be taking sick children to clinics where they could be tested, said Katherine Wells, the public health director in Lubbock, Texas. "If your kids are responding to fever reducers and you're keeping hydrated, some people may keep them at home," she said.
Most unvaccinated people will contract measles if they're exposed to the airborne virus, which can linger for up to two hours indoors. Those infected can spread the disease before they have symptoms. Around 1 in 5 people with measles end up hospitalized, 1 in 10 children develop ear infections that can lead to permanent hearing loss, and about 1 in 1,000 children die from respiratory and neurological conditions.
Gaines has a large Mennonite population, which often shuns vaccinations. "We respect everyone's right to vaccinate or not get vaccinated," said Albert Pilkington, CEO of the Seminole Hospital District, in the heart of the county, in an interview with Texas Standard. "That's just what it means to be an American, right?"
Local health officials have been trying to persuade the parents of unvaccinated children to protect their kids by bringing them to pop-up clinics offering measles vaccines.
"Some people who were on the fence, who thought measles wasn't something their kids would see, are recalculating and coming forward for vaccination," Wells said.
Local health departments are also operating mobile testing units outside schools in an attempt to detect infections before they spread. They're staffing clinics that can provide treatment prophylactically for infants exposed to the virus, who are too young for vaccination. Local health officials are advising day care centers on how to protect young children and babies, and educating school nurses on how to spot signs of the disease.
"I am putting 75% of my staff on this outbreak," Wells said. Although Lubbock isn't at the center of the outbreak, people infected have sought treatment there. "If someone infected was in the [emergency room], we need to identify everyone who was in that ER within two hours of that visit, notify them, and find out if they were vaccinated."
Local health departments in rural areas are notoriously underfunded. Wells said the workload has meant pressing pause on other programs, such as one providing substance abuse education.
Zach Holbrooks, executive director of the South Plains Public Health District, which includes Gaines, said health officials were following CDC guidelines, as of last year, by advising schools to keep unvaccinated children home for 21 days if they shared a classroom or the cafeteria with someone infected. This means that many parents may need to stay home from work to care for their kids.
"A lot of private schools have closed down because of a high number of sick children," Holbrooks said.
The burden of measles outbreaks multiplies as the disease spreads. Curbing a 2018 outbreak in Washington state with 72 cases cost about $2.3 million, in addition to $76,000 in medical costs, and an estimated $1 million in economic losses due to illness, quarantines, and caregiving.
Public health researchers expect such outbreaks to become larger and more common because of scores of laws around the U.S. — pending and recently passed — that ultimately lower vaccine rates by allowing parents to exempt their children from vaccine requirements at public schools and some private schools.
Such policies are coupled with misinformation about childhood vaccination now platformed at the highest levels of government. The new director of the Department of Health and Human Services, Robert F. Kennedy Jr., has erroneously blamed vaccines for autism, pointing to discredited theories shown to be untrue by more than a dozen scientific studies.
In Kennedy's first week on the job, HHS postponed an important meeting of the CDC's Advisory Committee on Immunization Practices, without saying when it would resume. In addition, the CDC's letter template to school principals, advising unvaccinated children to remain home from school for 21 days if they've been exposed to the measles virus, is no longer on the agency's website. An old version remains posted on its archive.
As a rule, at least 95% of people need to be vaccinated against measles for a community to be well protected. That threshold is high enough to protect infants too young for the vaccine, people who can't take the vaccine for medical reasons, and anyone who doesn't mount a strong, lasting immune response to it. Last school year, the number of kindergartners exempted from a vaccine requirement was higher than ever reported before, according to the Centers for Disease Control and Prevention.
In Gaines, exemptions were far higher than the national average, approaching 20% in 2023-24. Gaines has one of the lowest rates of childhood vaccination in Texas. At a local public school district in the community of Loop, only 46% of kindergarten students have gotten vaccines that protect against measles.
Amid an outbreak that displays the toll of measles in under-vaccinated pockets of America, Texas lawmakers have filed about 25 bills in this year's legislative session that could limit vaccination further. Lakshaman said the public — the majority of whom believe in the benefits of measles vaccination — should contact their representatives about the danger of such decisions. Her group and others offer resources to get involved.
"We've got children winding up in the hospital, and yet lawmakers who've got their blinders on," she said, referring to pending policies that will erode vaccination rates. "It's just mind-blowing."

How Animal Testing in US Could Be Transformed Under Trump
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Millions of animals each year are killed in U.S. laboratories as part of medical training and chemical, food, drug and cosmetic testing, according to the non-profit animal rights organization People for the Ethical Treatment of Animals (PETA). For many animals held captive for research, including a huge range of species from dogs, cats and hamsters to elephants, dolphins and many other species, pain is "not minimized," U.S. Department of Agriculture data shows. The issue of animal testing is something most Americans agree on: it needs to change and gradually be stopped. A Morning Consult poll conducted at the end of last year found that 80 percent of the 2,205 participants either agreed or strongly agreed with the statement: "The US government should commit to a plan to phase out experiments on animals." Since President Donald Trump began his second term, his administration has been making moves to transform and reduce animal testing in country, although the question remains as to whether it will be enough to spare many more animals from pain and suffering this year. Animal Testing In US Could Be Transformed Animal Testing In US Could Be Transformed Photo-illustration by Newsweek/Getty/Canva What Is The Trump Administration Doing About It? There have been various steps taken in different federal agencies to tackle the issue of animal testing since Trump was sworn in on January 20. In April, the Food and Drug Administration (FDA) announced it was "taking a groundbreaking step to advance public health by replacing animal testing in the development of monoclonal antibody therapies and other drugs with more effective, human-relevant methods." The FDA said that its animal testing requirement will be "reduced, refined, or potentially replaced" with a range of approaches, including artificial intelligence-based models, known as New Approach Methodologies or NAMs data. A Department of Health and Human Services (HHS) official told Newsweek: "The agency is paving the way for faster, safer, and more cost-effective treatments for American patients. "As we restore the agency's commitment to gold-standard science and integrity, this shift will help accelerate cures, lower drug prices, and reaffirm U.S. leadership in ethical, modern science." The National Institutes of Health (NIH) announced it was "adopting a new initiative to expand innovative, human-based science while reducing animal use in research," in alignment with the FDA's initiative. The agency said that while "traditional animal models continue to be vital to advancing scientific knowledge," new and emerging technologies could act as alternative methods, either alone or in combination with animal models. The NIH Office of Extramural Research told Newsweek it was "committed to transparently assessing where animal use can be reduced or eliminated by transitioning to [new approach methodologies (NAMs)]." "Areas where research using animals is currently necessary represent high-priority opportunities for investment in NAMs," the agency added. It added that it will "further its efforts to coordinate agency-wide efforts to develop, validate, and scale the use of NAMs across the agency's biomedical research portfolio and facilitate interagency coordination and regulatory translation for public health protection." During Trump's first term, the Environmental Protection Agency (EPA) signed a directive to "prioritize efforts to reduce animal testing and committed to reducing testing on mammals by 30 percent by 2025 and to eliminate it completely by 2035," an EPA spokesperson told Newsweek. Although, the spokesperson added: "the Biden Administration halted progress on these efforts by delaying compliance deadlines." As a member of the House, Lee Zeldin, the EPA's current administrator, co-sponsored various bills during Trump's first term regarding animal cruelty, covering issues such as phasing out animal-based testing for cosmetic products; ending taxpayer funding for painful experiments on dogs at the Department of Veteran Affairs; empowering federal law enforcement to prosecute animal abuse cases that cross state lines; and others, the spokesperson said. What The Experts Think Needs To Be Done The Trump administration's efforts to tackle the issue of animal testing appear to be a step in the right direction, according to experts who spoke with Newsweek. "I was pleasantly surprised and quite frankly a bit shocked to read the simultaneous announcements by the NIH and the FDA regarding a new emphasis on the use of alternatives to animals," Jeffrey Morgan, a professor of pathology and laboratory medicine at Brown University in Rhode Island, told Newsweek. Morgan, who is also the director of the Center for Alternatives to Animals in Testing at Brown University, said that both agencies are moving together in the same direction on the issue "sends a unified and very powerful message to the research and biotech communities." He added that the announcements showed "a major acknowledgement of the limitations of the use of animals in research and testing." "What is especially exciting is that the NIH announcement will encourage the entry of new investigators into the field, further accelerating innovation in alternatives with exciting impacts for both discovery and applied research across all diseases," he said. He added that the FDA announcement and its emphasis on a new regulatory science that embraces data from alternatives was "equally exciting." "The demands of this new regulatory science will likewise accelerate innovation because it will establish the much-needed regulatory framework for the rigorous evaluation of data from alternatives," he said. While the administration's initiatives to shift research away from animal testing is heading in the right direction, its policies are "overdue," Dr. Thomas Hartung, a professor in the department of environmental health and engineering at Johns Hopkins Bloomberg School of Public Health, Maryland, told Newsweek. "The animal tests for safety were introduced more than 50 years ago. There is no other area of science where we do not adapt to scientific progress," he said. Hartung added that animal "testing takes too long and is too expensive to really provide the safety consumers want." He said that running animal tests for new chemicals can cost millions and take years in some cases. "Nobody can wait that long, even if they can afford the testing costs," he said. Hartung also believes the shifts in the industry to reduce animal testing have been "coming for a while," as over the last two decades, America's opposition to animal use in medical research has been increasing. "The alignment of FDA and NIH really makes the difference now, which I think is evidence of a strong relationship of their leaderships," he said. Yet in order to make a real difference, Hartung said clear deadlines are key to show that "this is not just lip service." He also said that he thought "the transformative nature of artificial intelligence in this field is not fully acknowledged." "We also need an objective framework for change to better science, such as the evidence-based toxicology approach," he said.

ChatGPT use linked to cognitive decline, research reveals
Relying on the artificial intelligence chatbot ChatGPT to help you write an essay could be linked to cognitive decline, a new study reveals. Researchers at the Massachusetts Institute of Technology Media Lab studied the impact of ChatGPT on the brain by asking three groups of people to write an essay. One group relied on ChatGPT, one group relied on search engines, and one group had no outside resources at all. The researchers then monitored their brains using electroencephalography, a method which measures electrical activity. The team discovered that those who relied on ChatGPT — also known as a large language model — had the 'weakest' brain connectivity and remembered the least about their essays, highlighting potential concerns about cognitive decline in frequent users. 'Over four months, [large language model] users consistently underperformed at neural, linguistic, and behavioral levels,' the study reads. 'These results raise concerns about the long-term educational implications of [large language model] reliance and underscore the need for deeper inquiry into AI's role in learning.' The study also found that those who didn't use outside resources to write the essays had the 'strongest, most distributed networks.' While ChatGPT is 'efficient and convenient,' those who use it to write essays aren't 'integrat[ing] any of it' into their memory networks, lead author Nataliya Kosmyna told Time Magazine. Kosmyna said she's especially concerned about the impacts of ChatGPT on children whose brains are still developing. 'What really motivated me to put it out now before waiting for a full peer review is that I am afraid in 6-8 months, there will be some policymaker who decides, 'let's do GPT kindergarten,'' Kosmyna said. 'I think that would be absolutely bad and detrimental. Developing brains are at the highest risk.' But others, including President Donald Trump and members of his administration, aren't so worried about the impacts of ChatGPT on developing brains. Trump signed an executive order in April promoting the integration of AI into American schools. 'To ensure the United States remains a global leader in this technological revolution, we must provide our Nation's youth with opportunities to cultivate the skills and understanding necessary to use and create the next generation of AI technology,' the order reads. 'By fostering AI competency, we will equip our students with the foundational knowledge and skills necessary to adapt to and thrive in an increasingly digital society.' Kosmyna said her team is now working on another study comparing the brain activity of software engineers and programmers who use AI with those who don't. 'The results are even worse,' she told Time Magazine. The Independent has contacted OpenAI, which runs ChatGPT, for comment.

Trump administration makes sweeping changes to ObamaCare, ends ‘Dreamer' coverage
The Trump administration is shortening ObamaCare's annual open enrollment period and ending the law's coverage of immigrants that entered the U.S. illegally as children, according to a final rule announced Friday. The Biden administration made it easier and more affordable to sign up for Affordable Care Act plans, causing enrollment to swell to an all-time high. The Trump administration claims those moves opened a wave of fraudulent enrollment that's costing taxpayers billions of dollars. According to the rule, the federal open enrollment period will run from Nov. 1 through Dec. 31. Currently, federal open enrollment ends Jan. 15. States operating their own health insurance exchanges will have the flexibility to set their own open enrollments, so long as they run no longer than nine weeks between the November and December dates. In addition to the shortened enrollment period, the administration said it is ending ObamaCare coverage for immigrants that came into the U.S. illegally as children, also known as 'Dreamers.' The provision will undo a Biden-era rule that was estimated to allow 147,000 immigrants to enroll in coverage. A federal judge blocked the rule from being enforced in 19 states, and it is still being litigated. The administration also banned plans from covering 'sex-trait modification' as an essential health benefit beginning in plan year 2026. The policy will apply to the five states that currently include coverage for gender-affirming care, as well as in states that do not have such coverage expressly mentioned. But many of the other changes announced Friday will only last a year, like requiring more income verifications for people to enroll in coverage on federal exchange plans. The one-year sunset is a change from when the rule was proposed in March. It's designed to give Republicans on Capitol Hill an opportunity to codify the provisions into law for the long-term and use the savings to fund their massive party-line tax and spending bill. According to the Centers for Medicare and Medicaid Services (CMS), the rule is projected to save up to $12 billion in 2026 by 'reining in wasteful federal spending, and refocusing on making health insurance markets more affordable and sustainable for hardworking American families.' For instance, the rule requires federal exchange plans to check consumers' eligibility for special enrollment periods and raise the burden of verification for people who are automatically re-enrolled in subsidized plans. The rule also requires plans to charge those people a $5 monthly premium until they confirm or update their eligibility information. The rule also ends a monthly special enrollment period for people with income below 150 percent of the federal poverty line, which CMS said 'has been exploited to enroll consumers or change their plans without their knowledge.'
