(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.
It comes as South Carolina is dealing with the largest outbreak recorded since measles was declared eliminated within the U.S. in the year 2000.
A total of 20 states have reported cases so far including Arizona, California, Florida, Georgia, Idaho, Kentucky, Minnesota, Nebraska, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, South Dakota, Utah, Virginia, Washington, and Wisconsin.
Last year had a record breaking 2,276 cases nationwide, the highest number since 1992. There were also three measles deaths, the first in a decade.

(NEW YORK) — Nearly half of Americans — 152.3 million people — now live in places with unhealthy levels of ozone or particle pollution (PM2.5), two of the most dangerous air pollutants.
The American Lung Association’s 2026 “State of the Air” report finds that more than 129 million people live in counties with failing grades for ozone pollution. This type of pollution forms when sunlight interacts with compounds emitted from cars, industry and chemicals, creating harmful ground-level ozone in the air.
About 62 million people live in counties with failing grades for daily particle pollution spikes, which consist of tiny particles in the air produced by sources like car exhaust, power plants, construction, fires and dust, according to the report.
Exposure to dirty air was not equal, the report found.
People of color were more than twice as likely to live in areas failing all major pollution measures, according to the report.
“[In] areas where people have fewer socioeconomic resources … there’s a snowball effect because many of these areas may have less access to healthy food, less safe places to work out outside and less access to health care,” Dr. Afif El-Hasan, a board-certified pulmonologist and an American Lung Association spokesperson, told ABC News.
Many of these areas with high pollution are also underserved areas or have lower socioeconomic means, El-Hasan said.
Breathing in contaminated air not only makes people sicker; it affects family dynamics, finances and just about every other aspect of life, the report’s authors say.
Children are disproportionately affected as well. About 33.5 million of them are living in counties that received failing grades for at least one major air pollutant.
“Children who grow up in areas with polluted air are going to have decreased lung development compared to children who grow up having been exposed to clean air,” El-Hasan said. “Ultimately that leads to adults who have lower lung capacity than they would otherwise have — and that’s not reversible.”
And because the pollution compromises the body’s defenses, infections like the cold, flu and even COVID may be more severe in people who live in high-pollution areas, the findings suggested.
Despite decades of progress under the Clean Air Act, which was signed into law in 1970, the report found that air pollution is intensifying in many parts of the country.
Ozone pollution has worsened and now affects more people than in the past.
Climate change helps drive this trend by fueling extreme heat, drought and wildfires, the study suggested. And, while particle pollution has shown slight improvements, it still exposes far more people than historic low levels seen in the mid-2010s.
If you live in a place with poor air quality, there are steps you can take to protect your health, according to the American Lung Association.
Limit time outdoors on poor air quality days and check daily conditions. Use a high-quality mask like an N95 respirator and keep indoor air clean with filtration when pollution levels are high. Exercise indoors on bad air quality days.
Studies have also shown that staying up to date on vaccines, including flu and COVID shots, can also offer some protection.
Additionally, it’s critical the U.S. maintains the gains it has made on air quality over decades of stronger public health policies, El-Hasan said.
“Air does not respect borders — it will go everywhere,” El-Hasan said. “People should understand that what they do in terms of making sure policies are protecting air locally — it doesn’t just help you. If we are all helping keep our local air clean, it will help the rest of the nation as well.”

(NEW YORK) — So-called “night owls” may face a higher risk for heart attack and stroke, a new study published Wednesday finds.
Researchers found that “evening type” people had poorer cardiovascular health scores than those who were neither “morning type” or “evening type” people and had an associated 16% higher risk of heart attack and stroke.
The study, published in the Journal of the American Heart Association, analyzed survey and biometric data from more than 320,000 British adults aged 39 to 74.
Participants were asked whether they considered themselves a “definite morning” person, a “definite evening” person or somewhere in between, termed “intermediate.”
Researchers then calculated each person’s heart health using the American Heart Association’s Life’s Essential 8 (LE8) score. These factors include four health behaviors — diet quality, physical activity, sleep duration and nicotine exposure — and four health factors, including blood pressure, body mass index, blood sugar and blood fat levels.
“These are the factors the American Heart Association has identified as cardiovascular disease risk factors,” Kristen Knutson, associate professor of neurology and peventive medicine at Northwestern University Feinberg School of Medicine specializing in sleep and circadian rhythm research and fellow at the American Heart Association, told ABC News.
“Different people will have them in different combinations, but they are all correlated with one another,” she added.
Evening people were 79% more likely to have poor overall heart health compared with those in the intermediate group, the study found. Morning people did slightly better than the intermediate group, with a 5% lower risk of having a poor LE8 score.
Researchers found the evening people had a 16% higher risk of both heart attack and stroke. Researchers estimated that about 75% of this higher risk was explained by other LE8 factors, rather than sleep timing alone.
“It isn’t being a night owl that’s a problem,” Knutson said. “I think being a night owl who’s trying to live in a morning lark’s world is a conflict between one’s internal clock and their social clock.”
The higher risk appeared to be due to certain lifestyle behaviors and other health factors, the study found.
Nicotine use had the strongest impact on heart health, explaining 34% of the link between late bedtime and heart disease. Shorter sleep duration accounted for 14% of the extra risk, high blood sugar for 12% and body weight and diet each accounted for about 11% of the increased risk.
Behavioral effects of being a night owl were stronger in women than in men — women were 96% more likely to have lower LE8 scores compared to 67% in men, though they did not have a higher risk of heart attack or stroke.
“Women are further stressed by that lifestyle because they’re having to still get up and be the primary caregiver for family members,” Dr. Sonia Tolani, preventative cardiologist, Associate Professor of Medicine, and co-director of the Columbia University Women’s Heart Center, told ABC News.
Heart disease remains the leading cause of death in the U.S., according to the Centers for Disease Control and Prevention. The researchers concluded prevention efforts should focus on improving lifestyle habits when spending more time awake at night.
“The most obvious way is to quit smoking and that’s not new advice,” Knutson says. “But sleep regularity, meaning trying to go to bed at about the same time every day and not jumping around the clock — particularly on days off — can really help lead to regular timing of other behaviors like light exposure, meals, exercise activity.”
“Prioritize the low-hanging fruit” recommended Tolani. If an hour at the gym is not doable, “maybe you can find a way to do a 10-minute walk or cut a little bit of salt from your diet. Just try to make small changes,” she said.

(WASHINGTON) — President Donald Trump’s surgeon general nominee, Dr. Casey Means, indicated she supports vaccines but stopped short of recommending certain shots during her confirmation hearing before the Senate Health, Education, Labor and Pensions (HELP) committee on Wednesday.
Means, who has a medical degree but does not hold an active medical license, appeared hesitant to say that some vaccines, such as the flu vaccine, prevent serious disease.
When asked by HELP committee chair Sen. Bill Cassidy, R-La., if she would encourage mothers to vaccinate their children with the measles, mumps and rubella (MMR) vaccine amid widespread illness in the U.S., Means said, “I absolutely am supportive of the measles vaccine, and I do believe vaccines save lives and are important part of the public health strategy.”
However, she stressed personal autonomy and said each patient or parent needs to have a conversation with their doctor or pediatrician before taking any medication.
Later in the hearing, Sen. Tim Kaine, D-Va., asked Means for her opinion on the efficacy of the flu vaccine.
“Do you believe that there is evidence that the flu vaccine prevents serious disease and prevents hospitalization or deaths in children?” Kaine said.
“I believe that all patients should talk to their doctor–” Means began answering.
“And so do I, and that’s not what I’m asking,” Kaine interjected.
“I support the CDC’s guidance on the flu vaccine,” Means replied, adding that she believes the shot reduced the risk of hospitalization “at the population level.”
Earlier this year, the Centers for Disease Control and Prevention announced that it was changing the childhood immunization schedule, removing the universal recommendation for multiple shots, including the flu vaccine.
Means was originally scheduled to testify before the HELP committee in October, but her appearance was postponed for four months after she went into labor.
If confirmed, Means would become the nation’s top doctor, leading more than 6,000 members of the U.S. Public Health Service, including physicians, nurses, scientists and engineers working at various federal health agencies.
Means’ views largely mirror those of Health and Human Services Secretary Robert F. Kennedy Jr., with a focus on tackling the chronic disease epidemic, creating a healthier food supply and expressing vaccine skepticism.
