Measles in the U.S.: Latest Maps and Cases
Measles continues to spread in West Texas and New Mexico, with more than 250 people infected — many unvaccinated school-age children. Two cases in Oklahoma, for which state officials have not provided a location, have also been linked to these outbreaks. Eleven other states have reported isolated measles cases, typically linked to international travel.

The Texas outbreak began in late January, when local health officials reported two cases in Gaines County, a rural agricultural area on the western edge of the state.
The outbreak quickly escalated. Measles has spread into neighboring counties and infected at least 223 people as of Tuesday, including 29 people who have been hospitalized and an unvaccinated young child who died, the first such death in the United States in a decade.
New Mexico also declared an outbreak in Lea County, which borders Gaines County. While the cases in New Mexico have not officially been connected to the Texas outbreak, officials have said they are “undoubtedly related.”
Measles outbreaks in Texas and New Mexico
Last week, an unvaccinated resident of Lea County who tested positive for the virus died, though officials have not yet confirmed that measles was the cause of death.
In both states, most measles cases have spread among people who are unvaccinated or with unknown vaccine status.
For years, Gaines County has had low childhood vaccination rates, largely because of the area’s large Mennonite community. While there is no religious doctrine that explicitly forbids vaccines, the insular Christian group has historically avoided interacting with the health care system and has a long tradition of using home remedies and supplements.
Roughly 82 percent of the kindergarten students in the county had received the measles-mumps-rubella vaccination, or M.M.R., last year, which is far below the 95 percent coverage needed to prevent outbreaks in a community.
Texas public schools require children to have received certain vaccines, including the M.M.R. shot, but parents can apply for an exemption for “reasons of conscience,” including religious beliefs. Last year, Gaines County had one of the highest exemption rates in the state.
Vaccination rates can vary widely by school district. The Loop Independent School District in Gaines County is a small district with one school and the lowest rate of measles vaccination in the affected Texas counties. Only 46 percent of kindergarten students had received their M.M.R. vaccine in the 2023 school year, down from 82 percent in 2019.

Change in measles vaccination rates in affected Texas counties
In Lea County, N.M., the M.M.R. vaccination rate for children and teens is relatively high, at about 94 percent. But the rate among adults is much lower: 63 percent have received one shot of M.M.R., and only 55 percent have received both shots, according to local health officials, though they noted that there may be vaccinated adults whose records have not been added to the system. Adults make up more than half of reported cases in New Mexico.
Measles is one of the most contagious known infections. In a hypothetical community where nobody had immunity from the virus and each infected person infected 18 others, a small outbreak would quickly grow out of control:
Every vaccinated person would help slow the spread of the virus and limit the outbreak:
For the outbreak to end quickly, each infected person would need to infect fewer than one other person, on average. In this example, 17 of 18 people would need to be vaccinated — more than 94 percent of the community:
And while measles symptoms often resolve on their own within a few weeks, the virus can be extremely dangerous in rare cases. It may cause pneumonia, making it difficult for children to get oxygen into their lungs.
The infection can also lead to brain swelling, which can cause lasting damage, including blindness, deafness and intellectual disabilities. For every 1,000 children who get measles, one or two will die, according to the Centers for Disease Control and Prevention.
The virus also causes “immune amnesia,” making the body unable to defend itself against illnesses it has already been exposed to and leaving patients more susceptible to future infections.
Once someone is infected with the virus, doctors have little control over how serious a measles infection becomes — there is no antiviral for measles to stop its spread in the body, only “supportive care” to help manage symptoms. That’s why experts recommend that people get two doses of the M.M.R. vaccine, which are 97 percent effective at preventing infection.
Measles was officially declared eliminated — which means the virus is not continually spreading — in 2000, in large part because of aggressive vaccination campaigns. Experts now fear that status may be at risk, as childhood vaccination rates have been falling nationally.

A new report by the American Heart Association (AHA) included some troubling predictions for the future of women’s health.
The forecast, published in the journal Circulation on Wednesday, projected increases in various comorbidities in American females by 2050.
More than 59% of women were predicted to have high blood pressure, up from less than 49% currently.
The review also projected that more than 25% of women will have diabetes, compared to about 15% today, and more than 61% will have obesity, compared to 44% currently.
As a result of these risk factors, the prevalence of cardiovascular disease and stroke is expected to rise to 14.4% from 10.7%.

Not all trends were negative, as unhealthy cholesterol prevalence is expected to drop to about 22% from more than 42% today, the report stated.

Dr. Elizabeth Klodas, a cardiologist and founder of Step One Foods in Minnesota, commented on these “jarring findings.”
“The fact that on our current trajectory, cardiometabolic disease is projected to explode in women within one generation should be a huge wake-up call,” she told Fox News Digital.
NEARLY 90% OF AMERICANS AT RISK OF SILENT DISEASE — HERE’S WHAT TO KNOW
“Hypertension, diabetes, obesity — these are all major risk factors for heart disease, and we are already seeing what those risks are driving. Heart disease is the No. 1 killer of women, eclipsing all other causes of death, including breast cancer.”

Klodas warned that heart disease starts early, progresses “stealthily,” and can present “out of the blue in devastating ways.”
The AHA published another study on Thursday revealing one million hospitalizations, showing that heart attack deaths are climbing among adults below the age of 55.
The more alarming finding, according to Klodas, is that young women were found more likely to die after their first heart attack than men of the same age.
DOCTOR SHARES 3 SIMPLE CHANGES TO STAY HEALTHY AND INDEPENDENT AS YOU AGE
“This is all especially tragic since heart disease is almost entirely preventable,” she said. “The earlier you start, the better.”
Children can show early evidence of plaque deposition in their arteries, which can be reversed through lifestyle changes if “undertaken early enough and aggressively enough,” according to the expert.

Klodas suggested that rising heart conditions are associated with traditional risk factors, like smoking, high blood pressure, high cholesterol, diabetes, obesity and a sedentary lifestyle.

Doctors are also seeing higher rates of preeclampsia, or high blood pressure during pregnancy, as well as gestational diabetes. Klodas noted that these are sex-specific risk factors that don’t typically contribute to complications until after menopause.
The best way to protect a healthy heart is to “do the basics,” Klodas recommended, including the following lifestyle habits.

Klodas especially emphasized making improvements to diet, as the food people eat affects “every single risk factor that the AHA’s report highlights.”
“High blood pressure, high blood sugar, high cholesterol, excess weight – these are all conditions that are driven in part or in whole by food,” she said. “We eat multiple times every single day, which means what we eat has profound cumulative effects over time.”
“Even a small improvement in dietary intake, when maintained, can have a massive positive impact on health,” a doctor said. (iStock)
“Even a small improvement in dietary intake, when maintained, can have a massive positive impact on health.”
The doctor also recommends changing out a few snacks per day for healthier choices, which has been proven to “yield medication-level cholesterol reductions” in a month.

“Keep up that small change and, over the course of a year, you could also lose 20 pounds and reduce your sodium intake enough to avoid blood pressure-lowering medications,” Klodas added.
“Women should not view the AHA report as inevitable. We have power over our health destinies. We just need to use it.”

Nearsightedness (myopia) is skyrocketing globally, with nearly half of the world’s population expected to be myopic by 2050, according to the World Health Organization.
Heavy use of smartphones and other devices is associated with an 80% higher risk of myopia when combined with excessive computer use, but a new study suggests that dim indoor lighting could also be a factor.
For years, scientists have been puzzled by the different ways myopia is triggered. In lab settings, it can be induced by blurring vision or using different lenses. Conversely, it can be slowed by something as simple as spending time outdoors, research suggests.
Nearsightedness occurs when the eyeball grows too long from front to back, according to the American Optometric Association (AOA). This physical elongation causes light to focus in front of the retina rather than directly on it, making distant objects appear blurry.
The study suggests that myopia isn’t caused by the digital devices themselves, but by the low-light environments where they are typically used. (iStock)
Researchers at the State University of New York (SUNY) College of Optometry identified a potential specific trigger for this growth. When someone looks at a phone or a book up close, the pupil naturally constricts.
COMMON VISION ISSUE COULD LEAD TO MISSED CANCER WARNING, STUDY FINDS
“In bright outdoor light, the pupil constricts to protect the eye while still allowing ample light to reach the retina,” Urusha Maharjan, a SUNY Optometry doctoral student who conducted the study, said in a press release.

“When people focus on close objects indoors, such as phones, tablets or books, the pupil can also constrict — not because of brightness, but to sharpen the image,” she went on. “In dim lighting, this combination may significantly reduce retinal illumination.”
High-intensity natural light prevents myopia because it provides enough retinal stimulation to override the “stop growing” signal, even when pupils are constricted. (iStock)
The hypothesis suggests that when the retina is deprived of light during extended close-up work, it sends a signal for the eye to grow.
In a dim environment, the narrowed pupil allows so little light through that the retinal activity isn’t strong enough to signal the eye to stop growing, the researchers found.

In contrast, being outdoors provides light levels much brighter than indoors. This ensures that even when the pupil narrows to focus on a nearby object, the retina still receives a strong signal, maintaining healthy eye development.

The team noted some limitations of the study, including the small subject group and the inability to directly measure internal lens changes, as the bright backgrounds used to mimic the outdoors made pupils too small for standard equipment.
Researchers believe that increasing indoor brightness during close-up work could be a simple, testable way to slow the global nearsightedness epidemic. (iStock)
“This is not a final answer,” Jose-Manuel Alonso, MD, PhD, SUNY distinguished professor and senior author of the study, said in the release.

“But the study offers a testable hypothesis that reframes how visual habits, lighting and eye focusing interact.”
The study was published in the journal Cell Reports.
