(NEW YORK) — A Texas appeals court will hear arguments on Thursday in a civil lawsuit brought against a woman accused by the state of illegally providing abortions in the Houston area.

Maria Margarita Rojas allegedly provided abortions in violation of the state’s abortion ban and was practicing medicine without a license at a network of clinics in northwestern Houston, according to Texas Attorney General Ken Paxton.

Last year, a lower court in Waller County issued an injunction against Rojas and the three clinics at which she worked, causing them to shut down.

The Center for Reproductive Rights is currently asking the appellate court to reverse that decision.

Meanwhile, prosecutors have also accused Rojas of violating the state’s abortion ban and charged her with a first-degree felony that carries a potential sentence of up to life in prison.

“[Paxton] is accusing our client of basically operating abortion clinics, which the problem is that the allegations just aren’t true and we think that the state completely failed to prove or show that any abortions were happening or that any unlawful practice was happening at the clinics,” Marc Herron, interim associate director of litigation with the CRR, who is representing Rojas in the civil case, told ABC News.

ABC News has also reached out to the attorney representing Rojas in the criminal case.

Herron said the case against Rojas is significant because it marks the first time a provider has been criminally charged in Texas for violating the state’s abortion ban.

He accused Paxton’s office of conducting a “shoddy” investigation and said Rojas was using the abortion drug misoprostol to provide miscarriage care.

In January 2025, an anonymous complaint was filed with the Texas Health and Human Services Commission, alleging that two abortions were performed at one of Rojas’ clinics, according to the appellate brief.

The Medicaid Fraud Division within Paxton’s office began investigating, with one investigator claiming to find a pill bottle of the drug misoprostol, according to the complaint. While misoprostol can be used as part of a two-drug combination to induce an abortion, it is also used to treat first-trimester miscarriages.

In filing an appeal, Rojas’ attorneys argued that mifepristone, the drug given with misoprostol to induce an abortion, was never found by investigators, nor were tools found that would be used in a surgical abortion.

They also alleged the state investigators had no “medical training or expertise” to know what misoprostol could be used for and did not consult with a medical expert during the investigation.

Herron said the effects of the investigation and of the charges have been devastating on Rojas.

“I think this is a politically motivated case and the effect has been to completely upend my client’s life,” Herron said. “She was arrested twice. She was held in jail for 10 days and had to post this exorbitant $1.4 million bond. She’s now out, but she’s got to wear an ankle monitor. There are extreme restrictions on her travel. Her midwifery license has been temporarily suspended pending the outcome of the criminal proceedings, which could take years.”

He added that the proceedings have also affected the predominantly Spanish-speaking, low-income, uninsured patients who relied on care from Rojas and her clinics.

“People who relied on Mrs. Rojas for midwifery care — she delivered babies,” Herron said. “She was a caring, devoted midwife who delivered babies and provided care to her patients, and now her patients can’t turn to her. So this has been devastating.”

According to a press release last year from Paxton, Rojas is a midwife known as “Dr. Maria.” She allegedly owned and operated multiple clinics, including Clinica Waller Latinoamericana in Waller, Clinica Latinoamericana Telge in Cypress and Latinoamericana Medical Clinic in Spring — all in the northwest Houston area.

Rojas is accused of performing “illegal abortion procedures” in her clinics, which allegedly violated the Texas Human Life Protection Act, the attorney general’s office said.

Abortions are banned in Texas except in limited, exception cases if the woman has a life-threatening condition or is at risk of “substantial impairment of a major bodily function.”

In the limited exceptions when abortion is allowed, patients are required to make two trips, one for an in-person counseling session and then 24 hours later for the abortion, according to the Guttmacher Institute, a research group that focuses on sexual and reproductive health

‘Very concerning’: How EPA rolling back greenhouse gas emissions endangerment finding could impact health

(WASHINGTON) — The Trump administration walked back an Obama-era environmental decision that has been the legal basis for establishing federal regulation of greenhouse gas emissions.

The Environmental Protection Agency (EPA) said on Thursday it was rescinding the 2009 endangerment finding, which determined that six key greenhouse gases threaten human health and welfare.

The regulations that resulted cover everything from vehicle tailpipe emissions to the release of greenhouse gases from power plants and other significant emission sources.

President Donald Trump called the move “the single largest deregulatory action in American history” and said the repealed finding had “no basis in fact” and “no basis in law.”

The endangerment finding stemmed from the 2007 Supreme Court decision Massachusetts v. EPA, which held that the EPA could regulate greenhouse gases from motor vehicles under the 1970 Clean Air Act because those gases are air pollutants.

Some environmental scientists disagree, telling ABC News that the rescission is concerning and could have major implications for health. They add that decades of research has shown the impact climate change has on human health.

“The evidence is so overwhelming,” Dr. Ana Navas-Acien, chair of the department of environmental health sciences at Mailman School of Public Health at Columbia University, told ABC News.

“The scientific evidence showing the connection between greenhouse emissions, climate change and then the related health effects — it’s massive, it’s substantial, it has been reviewed by independent organizations,” she said. “So, the fact that this body of evidence has become so well established, it just speaks to the level of rigorous science that has been done.”

How greenhouse gases, climate change impact health

Research has shown that greenhouse gases — such as carbon dioxide and nitrous oxide — drive climate change, and, in turn, can harm human health by exposing people to events including wildfire smoke, extreme heat, flooding and waterborne diseases.

For example, rising temperatures have direct harms on health by increasing risk of dehydration and causing more stress on the heart.

During heat waves, the risk of death from heart attack increases by 64%, according to a 2024 study from researchers at Yale School of the Environment.

Additionally, a 2025 study from Yale School of Public Health found that between 2000 and 2020, there were more than 3,400 preventable deaths in the contiguous U.S. due to high temperatures.

The World Health Organization has warned there will be an estimated 250,000 additional deaths around the world annually from 2030 to 2050 due to climate change-related heat exposure.

“We have recent studies showing heat exposure can lead to heart attack events … and it goes beyond just the cardiovascular system,” Kai Chen, an associate professor of epidemiology at Yale School of Public Health and faculty director of the Yale Center on Climate Change and Health, told ABC News. “It goes beyond these kinds of physical conditions or physical health, [also] impacting our mental health.”

High temperatures can also negatively impact the quality and quantity of sleep, which can raise levels of cortisol in the body.

Studies have also shown that extreme heat can exacerbate conditions such as depression, anxiety and suicide ideation. For the latter, a 2023 meta-analysis found that even a slight bump in the average monthly temperature can lead to increases in suicide and suicidal behavior.

“So, really, heat can lead to a broad spectrum of diseases,” Chen added.

In recent decades, wildfires in the western U.S. have become larger, more intense, and more destructive due to a combination of factors, including human-amplified climate change and rapid urbanization, according to the federal government’s Fifth National Climate Assessment.

The same report found that these fires are worsening air quality in many part of the country due to wildfire smoke, which is a mixture of gases, water vapor, air pollutants and fine particulate matter. The latter, known as PM2.5, is at least 30 times smaller in diameter than a human hair.

Experts say these particles are of concern because they are too small to be seen with the naked eye and can easily enter the nose and throat. They can travel to the lungs and even circulate in the bloodstream.

PM2.5 can cause both short-term health effects, even for healthy people, including irritation of the eyes, nose and throat; coughing, sneezing; and shortness of breath and long-term effects such as worsening of conditions such as asthma, heart disease or chronic obstructive pulmonary disease flare-ups.

“Recent evidence has shown that the fine particulate matter in the air can also impact dementia and cognitive function,” Chen said. “It can also affect birth outcomes, leading to pre-term birth and low birth weight. So, air pollution is a major risk factor.”

Regulating fossil fuel combustion reduced PM2.5-related deaths by approximately 54% from 1990 to 2010, according to 2018 joint study from researchers in the U.S. and China.

Short- and long-term implications

Navas-Acien believes that, in the short-term, the rescinding of the endangerment finding will lead to higher pollution levels.

“Higher pollution levels, if we allow that to happen, that means more pollutants in the air that we breathe, in the water that we drink, in the food that we eat,” she said. “And that’s going to result in a higher burden of chronic diseases and even not just chronic disease, but also like heart attacks.”

Research has shown that in the days following an increased level of air pollutants, there are more visits to emergency rooms and hospital admissions for cardiorespiratory events, according to Navas-Acien.

“So that tells you that the impacts of pollution, in the short term, are very rapid,” she added.

In the absence of federal protections, Navas-Acien and Chen said state and local leaders can take actions to reduce greenhouse gas emissions and improve air quality.

On the individual level, to protect yourself, the experts recommend frequently checking the air quality in your area, wearing a mask if air pollution levels are high and supporting the creation of urban green spaces to combat climate change.

Chen said the EPA rescinding the endangerment finding is “very concerning” because “the scientific evidence has not become weaker, but actually became much stronger, showing the health harms from the climate change stirring from the greenhouse gas emissions. This rollback of policy will actually be threatening millions of Americans’ lives.”

“Climate change is impacting our health right now,” Chen continued. “It’s not a political debate. It is science and the science is clear. We need to take action.”

(NEW YORK) — There have been at least 733 confirmed measles cases reported across the nation, the latest data from the Centers for Disease Control and Prevention showed Friday.

In just a few weeks, the United States reported four times as many cases than typically seen throughout an entire calendar year.

Before last year, which had a record breaking 2,276 cases, the U.S. averaged 180 cases annually since measles was declared eliminated in 2000.

The record numbers come as South Carolina is dealing with the largest outbreak recorded in recent memory.

Other states that have reported cases and are dealing with ongoing outbreaks include Arizona, California, Florida, Georgia, Idaho, Kentucky, Minnesota, Nebraska, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, South Dakota, Utah, Virginia, Washington, and Wisconsin.

Most of the outbreaks occurring across the country are in pockets of under-vaccinated or unvaccinated communities.

The rate of kindergartners vaccinated with the measles, mumps, and rubella (MMR) vaccine has fallen from 95% in 2019 to below 93% in 2025, CDC data shows. Herd immunity, a threshold for vaccination rates that slow a virus’ ability to spread, is typically achieved at 95% vaccination rates, public health experts say.

Declining vaccination rates have left approximately 300,000 kindergarteners unprotected from measles infection.

The MMR vaccine is given in two doses, the initial shot given after the first year of life and the second shot given after the fourth year of life.

(WASHINGTON) — Congress has approved legislation for a funding fix that fully supports the World Trade Center Health Program and prevents a projected multibillion-dollar shortfall that threatened the program’s future.

At a press conference Thursday morning, Sen. Kirsten Gillibrand, D-N.Y., highlighted the action as a critical step toward protecting long-term care for those sickened by toxic exposure after the Sept. 11 attacks.

“Fully funding the World Trade Center Health Program honors our promise to never forget 9/11 survivors and the brave first responders who put their lives on the line for our country,” Gillibrand said. 

Since its creation in 2011 through an act of Congress, the program reports it has helped over 150,000 individuals get care and medical monitoring. Gillibrand said the package will fully fund the program through 2040.

The new measure updates how the program is financed, allowing it to meet rising medical costs and growing enrollment without the risk of sudden funding gaps.

Supporters say the change provides long-term stability for the thousands of people whose health was harmed by exposure to toxic chemicals after the Sept. 11 terror attacks in New York, Pennsylvania, and Washington, D.C.

“Making sure our 9/11 first responders and survivors have the resources they need to cope with the long-term health effects from toxic exposure has been one of my top priorities for my entire service in Congress,” Gillibrand said. “I am relieved that, after years of fighting tirelessly for its passage, this funding has been signed into law.”

The World Trade Center Health Program provides medical monitoring and treatment for first responders, cleanup workers, and community members affected by 9/11-related exposure. Advocates stressed that stable funding is critical not only for current patients but also for people who may develop related illnesses years or decades later.

Doctors, responders, advocates, and survivors have long warned that the program faced a looming financial crisis.

Enrollment has continued to grow as more people develop cancers and chronic conditions linked to toxic dust and debris, while aging patients require more complex care, Benjamin Chevat, executive director for nonprofit Citizens for the Extension of the James Zadroga Act, told ABC News.

An outdated funding formula failed to reflect those realities, raising concerns that treatment could be delayed or limited, advocates cautioned.

Still, supporters say funding alone does not resolve all of the program’s challenges.

“Finally, fully funding the World Trade Center Health Program after so many years is a real accomplishment, for the 9/11 responders and survivors who walked the halls of Congress and called their representatives, and for Rep. Andrew Garbarino and Sen. Gillibrand among others who worked to get it done,” Chevat said.

The James Zadroga 9/11 Health and Compensation Act is named after a New York City Police Department officer whose 2006 death was linked to exposures from the World Trade Center disaster.

Chevat said that some challenges remain for the program.

Certification of new conditions has slowed, staffing shortages persist at some clinical sites, and administrative backlogs have delayed care for certain patients, Chevat said. Addressing these issues will ensure the program can fully deliver on its mission, he added.

Why are so many younger Americans getting and dying of colorectal cancer?

(NEW YORK) — Colorectal cancer was once viewed as being mostly diagnosed among middle-age and older adults, but that’s changing.

Research shows more adults in their 20s, 30s and 40s are being diagnosed with colorectal cancer, with incidence increasing over the last three decades.

Deaths are on the rise too, with a recent study finding colorectal cancer is now the leading cause of cancer-related deaths in men — and second in women, under age 50.

“It’s definitely incredibly concerning that these rates continue to rise and that we really don’t know why this is happening,” Dr. Andrea Cercek, a gastrointestinal medical oncologist at Memorial Sloan Kettering Cancer Center in New York City, told ABC News.

Oncologists told ABC News that it’s important to get the word out about how colorectal cancer is affecting younger adults in an effort to try and reverse the trends.

Colorectal cancer rising among younger adults
According to the American Cancer Society (ACS), incidence of colorectal cancer in adults between ages 20 and 39 has been rising about 2% every year since the mid-1990s.

What’s more, about one in five people currently being diagnosed with colorectal cancer are under age 55, ACS states.

“Two-thirds of the young patients present already as stage three and four, which is a sad fact,” Dr. Y. Nancy You, a professor of surgery in the department of colon & rectal surgery and medical director of the young-onset colorectal cancer program at MD Anderson Cancer Center in Houston, told ABC News.

Research shows it’s not only colorectal cancer cases that are on the rise among younger adults but deaths as well.

A study published earlier this month from ACS in the medical journal JAMA found that as of 2023, colorectal cancer has surpassed all other cancers as the leading cause of cancer deaths among Americans under age 50.

Since 2005, deaths from colon and rectal cancers in those under age 50 have risen by 1.1% every year, the study found.

“Whenever we see rates increasing for cancers in younger individuals, it does lead to concern as to why this is happening and also how these individuals may know that they could start screening at younger ages,” Dr. Veda Giri, a professor of internal medicine (medical oncology) and director of the early onset cancer program at at Yale School of Medicine, told ABC News.

“So, the concern comes up not only about why, but what can we do now based on our available ways of screening, detecting and treating cancers that we can now implement in this space of early onset colorectal cancer,” she added.

Why are cases, deaths related to colorectal cancer rising?
Oncologists told ABC News they’re not sure why there’s an increase in colorectal cancer among younger adults, but research is ongoing.

Giri said some the rise could be tied to a higher consumption of ultra-processed foods and processed meats along with a lower intake of fiber or other food substances.

She said a great deal of research is being focused on the gut microbiome and whether disruptions from external exposures, such as diet or environment, may play a role.

“There’s been some work going on trying to characterize obesity patterns and rise in colorectal cancer,” Giri said. “Obesity might be a proxy for things like sedentary lifestyle, eating of these ultra-processed foods, and we certainly see a spectrum of patients where some with early onset colorectal cancer may have obesity, but they’re also individuals that are not obese.”

Risk factors including smoking and heavy alcohol use and have been linked with a higher likelihood of developing colorectal cancer.

A family history of colorectal cancer or colon polyps can also raise the risk of colorectal cancer as can genetic conditions such as Lynch syndrome.

Additionally, inflammatory bowel diseases, including chronic ulcerative colitis and Crohn’s disease, can lead to long-term colon inflammation and raise the risk of colorectal cancer.

Experts believe that whatever is behind the rise, it’s likely to be caused by multiple factors rather than one factor.

“I don’t think it’s going to be a single smoking gun,” You said. “I think cancer is a complex disease. It’s heterogeneous. What makes a cell turn cancerous is probably a lot of factors.”

How to reverse the trend
In 2021, the U.S. Preventive Services Task Force lowered the recommended age at which people at average risk should start screening from age 50 to age 45.

For those with a family history of colon cancer, doctors say people should start screening at either age 40 or 10 years before the age a family member was diagnosed, whichever comes first. 

“If we can identify individuals at risk, then we could screen those individuals earlier,” Cercek said. “The problem is that we’ve lowered already screening age to 45, which captured a lot of the population, but the steepest rise is actually the 20 to 30 year olds.”

Doctors said they hope highlighting the risk younger Americans face will raise awareness and help them pay attention to any symptoms they develop.

The most common symptoms of colorectal cancer include persistent changes in bowel habits, unfinished bowel habits, rectal bleeding or blood in stool, abdominal pain or discomfort, unexplained weight loss and fatigue.

“We definitely don’t want to create like a reign of terror where any little thing will trigger a cancer worry or cancer workup,” You said. “But at the same time, I think there’s room to improve in terms of whenever somebody does present with symptoms to get them to a cancer workup faster than what is happening today.”

(NEW YORK) — At least 588 measles cases have been confirmed so far this year across the U.S., according to updated data from the Centers for Disease Control and Prevention.

This means the U.S. has seen more cases in about one month than is typically recorded in an entire year.

Only nine other years, including last year, have had higher case counts since measles was declared eliminated in 2000.

The high case counts in 2026 are largely being driven by a measles outbreak in South Carolina.

At least 17 states have also reported measles cases this year including Arizona, California, Florida, Georgia, Idaho, Kentucky, Minnesota, Nebraska, North Carolina, Ohio, Oregon, South Carolina, South Dakota, Utah, Virginia, Washington and Wisconsin.

Almost all cases are tied to ongoing outbreaks in pockets of undervaccinated or unvaccinated communities. Just three measles cases were reported among international travelers so far this year, according to CDC data.

Last year, the U.S. saw a record-breaking number of measles cases reported with 2,257 infections, the highest figure recorded since 1992. The U.S. could be on pace to surpass that record if cases continue to mount at this rate.

The CDC currently recommends that people receive two doses of the measles, mumps, rubella (MMR) vaccine, the first at ages 12 to 15 months and the second between 4 and 6 years old. One dose is 93% effective, and two doses are 97% effective against measles, the CDC says.

However, federal data shows vaccination rates have been lagging in recent years. During the 2024-2025 school year, 92.5% of kindergartners received the MMR vaccine, according to data. This is lower than the 92.7% seen in the previous school year and the 95.2% seen in the 2019-2020 school year, before the COVID-19 pandemic.

The national trends mirror those see in counties across the U.S. A recent map from ABC News — a collaboration with researchers from Boston Children’s Hospital, Harvard School of Medicine and Icahn School of Medicine at Mt. Sinai that allows people to type in their ZIP code and see the measles risk in their area — found a wide range of risks in areas across the U.S.

Some counties and ZIP codes fell into the “lowest risk,” with 85% or more of children under 5 years old receiving one or more measles vaccine dose to “very high risk” with fewer than 60% of children under age 5 receiving one or more measles vaccine dose.

Everything to know about Nipah virus amid cases being detected in India

(NEW YORK) — Several countries, including Thailand and Nepal, have increased their surveillance after cases of the deadly Nipah virus were detected in India.

So far, just two cases have been confirmed among 25-year-old nurses, a woman and a man, in West Bengal, according to the World Health Organization.

A spokesperson for the Department of Health and Human Services told ABC News earlier this week that Indian health authorities have deployed an outbreak response team and the Centers for Disease Control and Prevention is in contact with local officials. The CDC said it is “monitoring” the situation.

Despite the virus’s high fatality rate, experts have said it’s very unlikely it will lead to a global emergency.

Here’s what you need to know about the virus, including signs and symptoms, how the virus is transmitted and what treatments are available.

What is Nipah virus?

Nipah virus is a type of zoonotic disease, meaning it’s primarily found in animals and can spread between animals and people.

It was first discovered in 1999 after a disease affected both pigs and people in Malaysia and Singapore, according to the CDC.

The virus is most often spread by fruit bats, and can spread through direct or indirect contact.

The virus can also spread from person to person by being in close contact or coming into contact with the bodily fluids of an infected person.

What are the symptoms?

Symptoms typically occur between four and 14 days after exposure. The most common symptom is fever followed by headache, cough, sore throat, difficulty breathing and vomiting.

Diagnosing the virus in the early stages is often difficult because the symptoms resemble many other illnesses, the CDC has said.

The virus can lead to severe symptoms, including disorientation, drowsiness, seizures or encephalitis, which is inflammation of the brain. These can progress to a coma within 24 to 48 hours, according to the CDC.

Deaths range anywhere between 40% and 75% among all cases, the federal health agency said. Some permanent changes among survivors have been noted, including persistent convulsions.

What are the treatments available?

Currently there are no specific treatments available for Nipah virus other than managing symptoms with supportive care, including rest and fluids.

Experts said there are treatments currently under development. One is a monoclonal antibody, a treatment that uses immune system proteins manufactured in a lab. They mimic the antibodies the body naturally creates when fighting the virus.

Dr. Diana Finkel, an associate professor of medicine in the division of infectious disease at Rutgers New Jersey Medical School, previously told ABC News that the drug has already completed phase I clinical trials and is currently being used on a compassionate basis.

Researchers are also studying the potential benefit of remdesivir — the intravenous medication used to treat COVID-19 — which has been shown to work well in nonhuman primates with Nipah virus.

What is the likelihood of Nipah virus spreading?

Experts said that while anything is possible, it’s very unlikely that cases in India will lead to global spread.

“The world is small, but the likelihood that somebody’s infected, or an infected fruit bat with Nipah virus would be here, right now, is very unlikely,” Finkel previously told ABC News.

She said when people are exposed in health care settings, it’s often because proper standard precautions were not followed, such as not wearing gloves or masks.

Experts have said Nipah virus cases are also a reminder of the potentially devastating effects of habitat destruction and climate change, possibly leading to more interaction between infected animals and humans.

“You have to think about why are fruit bats that harbor this Nipah virus, why are they coming into contact with people?” Dr. Peter Rabinowitz, director of the University of Washington Center for One Health Research, previously told ABC News. “What is changing in terms of the movement of the bat populations? Are they leaving [a] habitat where there were not very many people? Are they now spending more time close to people?”
