NIH director Dr. Jay Bhattacharya to take over as acting head of CDC
(WASHINGTON) — Dr. Jay Bhattacharya, director of the National Institutes of Health (NIH), will take over as acting director of the Centers for Disease Control and Prevention, a White House official and sources familiar with the matter told ABC News.
Bhattacharya will continue in his current duties as NIH director until a permanent CDC director is nominated and confirmed, according to the White House official.
He replaces Jim O’Neill, who served as acting director of the CDC from late August 2025 until he stepped down last week.
O’Neill will be nominated as the next head of the National Science Foundation, according to the White House official.
(NEW YORK) — Long-term alcohol use has been linked to higher risks of colorectal cancer, according to a study published Monday in the journal Cancer.
Researchers found that those with heavy lifetime alcohol consumption have up to a 91% higher risk of developing colorectal cancer compared with those who drank very little. That risk significantly increased with consistent heavy consumption, whereas those who quit drinking may have demonstrated decreased risk of precancerous tissue.
“The longer someone drinks, the longer their colon and rectum are exposed damage and impaired repair, both major mechanisms of cancer,” Dr. Lynn M O’Connor, section chief of colon and rectal surgery at Mercy Medical Center and St. Joseph Hospital in New York, told ABC News.
The study followed more than 88,000 adults with no prior history of cancer. Participants reported their alcohol use beginning in early adulthood and were followed for nearly a decade to track cancer outcomes.
Compared with those who averaged one drink or less per week over their lifetime, those who consumed over 14 drinks a week had a 25% higher risk of developing colorectal cancer. The link was even stronger for rectal cancer, where one’s risk nearly doubled.
Rectal cancer is “often more difficult to treat and more involved clinically, which makes screening and early identification all the more important,” Dr. Jeffrey Farma, a colorectal cancer specialist, told ABC News.
The results come as colorectal cancers are on the rise, especially in younger people.
“We’re seeing an uptick in rectal cancers. If alcohol affects the lower part of the colon differently —we need to understand why,” Dr. Fola May, a GI specialist and associate director of the UCLA Kaiser Permanente Center for Health Equity, told ABC News.
In the study, researchers found the highest risks among people who drank heavily at every stage of life. Those who consistently exceeded recommended drinking limits across each stage of adulthood had a 91% higher risk of colorectal cancer compared with lifelong light drinkers or those with gaps in heavy drinking.
“These numbers are not guarantees, but signals to do something before it’s too late,” May said. “Colorectal cancer is one of the few cancers we can actually prevent or catch early, but fewer than 70% of eligible people get screened.”
The study also looked at adenomas —polyps that can develop into cancer. While heavy drinking was not strongly linked to adenoma risk, those who quit drinking had significantly lower odds of developing nonadvanced adenomas compared to light drinkers.
“These are modifiable risks. The choices people make over time matter, and the body can respond when those risks are reduced,” Farma said.
The results align with a growing body of evidence linking alcohol, a well-recognized carcinogen, to colorectal cancer.
Colorectal screening is recommended for all adults starting at age 45 according to the United States Preventative Services Task Force. Screening tools include annual stool tests, CT scans every five years, or colonoscopies every 10 years.
“Everyone should be screened. It saves lives, and people are dying unnecessarily when they put it off,” May said.
Those who may be at higher risk may need to be screened at an early age or more often than typically recommended.
“If you’ve had prolonged heavy drinking and you develop symptoms like bleeding or persistent changes in bowel habits, you need to be evaluated — even in your 30s,” Farma said. “That’s how we catch this early and save lives.”

(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.
(NEW YORK) — Maternal mortality rates in the United States have dropped to their lowest levels in recent years, according to new data published on Thursday.
The report, from the Centers for Disease Control and Prevention’s National Center for Health Statistics, compared maternal deaths in 2023 and 2024, with maternal deaths defined as the death of a woman during pregnancy or within 42 days of pregnancy termination.
In 2024, 649 women died of maternal causes in the U.S., with a rate of 17.9 deaths per 100,000 births, according to the report.
By comparison, 669 women died in 2023 with a rate of 18.6 deaths per 100,000 births, the report found.
This is also the lowest rate seen since 2018, which had a maternal mortality rate of 17.4 deaths per 100,000 live births.
Data showed significant racial/ethnic disparities. Black women had the highest mortality rate at 44.8 deaths per 100,000 live births.
This was three times higher than the mortality rate for white women of 14.2 deaths per 100,000 live births. Hispanic and Asian women also had lower rates of 12.1 deaths per 100,000 and 18.1 deaths per 100,000, respectively.
Research has shown that Black women are more likely to have pre-existing cardiovascular disease and are more likely to experience adverse pregnancy outcomes, both of which increase the risk of maternal mortality.
Between 2023 and 2024, rates for Black, white and Hispanic women declined while the rate for Asian women rose, but neither the decreases nor the increase was “significant,” according to the report.
There were also disparities by age. Women aged 40 and older had the highest maternal mortality rate of 62.3 deaths per 100,000 live births in 2024.
This was 4.5 times higher than the mortality rate for women younger than age 25, which sat at 13.7 per 100,000 and 3.7 times higher than the rate for women between ages 25 and 39, sitting at 16.5 per 100,000. The report describes the differences in the women aged 40 and older group with the younger groups as “significant.”
More than 80% of pregnancy-related deaths are preventable, according to the CDC. The report did not examine why the maternal mortality rate declined, but the CDC has taken steps to support efforts to prevent pregnancy-related deaths.
Among these are Hear Her, which is a national campaign that shares messages about signs and symptoms during and after pregnancy that warrant seeking urgent medical care.
Additionally, the CDC conducts national surveillance through the Pregnancy Mortality Surveillance System, which is used to better understand the risk factors for and causes of pregnancy-related deaths in the U.S.
