Measles has held “eliminated” status in the United States since 2000, a designation that means there had been no year-long, uncontrolled spread of the virus within the country for decades. But that milestone is now in jeopardy.

The infection is spreading again, and the Centers for Disease Control and Prevention (CDC) has reported 1,596 confirmed cases this year, the highest annual total in over thirty years. The actual number could be higher, says Dr. Paul Offit, director of the Vaccine Education Center at the Children’s Hospital of Philadelphia.

Measles Case Surge In The US

Since August 2025, more than 100 people have been infected in the Utah–Arizona border region, forming the second-largest measles cluster in the U.S. this year. Most patients were unvaccinated, and the virus has now moved beyond small religious circles into the general population. This outbreak followed the earlier “Southwest wave,” which infected over 880 people in Texas, New Mexico, and Oklahoma, sending national measles numbers to a 34-year record high.

Experts warn that the current pattern resembles the major outbreaks seen in the early 1990s, before widespread vaccination programs curbed transmission. The largest outbreak occurred in West Texas, where 99 people were hospitalized and two unvaccinated school-age children died — the first measles deaths in the country since 2015. The Texas Department of State Health Services declared that outbreak over in mid-August. New Mexico has also reported a measles-related death, according to CNN. In response, the CDC has sent emergency teams to Utah, Arizona, Minnesota, and South Carolina to help limit the spread.

What Is Causing Measles to Increase in the U.S.?

In Mohave County, Arizona, vaccination coverage among kindergartners dropped from 91% in 2019–20 to 78% in 2024–25, with a similar decline noted in southwest Utah.

Public health experts stress that at least 95% vaccination coverage is necessary to prevent the virus from spreading. Both Utah and Arizona allow parents to exempt children from school vaccine mandates on personal or religious grounds, leaving pockets of unprotected populations.

According to The Times of India, vaccine hesitancy has deepened since the Covid-19 pandemic, fueled by political polarization and a decline in public trust toward health authorities. Notably, most of the affected towns voted heavily for Donald Trump in the 2024 election, underscoring how politics and misinformation continue to shape vaccination decisions.

Will the U.S. Lose Its Measles Elimination Status?

In November, the Pan American Health Organization (PAHO), the regional arm of the World Health Organization (WHO) will hold its annual Measles and Rubella Elimination Regional Monitoring and Re-Verification Commission meeting to review each country’s elimination status.

The WHO defines a loss of elimination status as continuous transmission lasting longer than 12 months. While there are no direct penalties, re-establishing measles as an endemic disease would mark a major public health setback, leading to avoidable deaths and straining local healthcare systems.

Countries that lose their elimination status are required to submit a corrective action plan, typically involving intensive vaccination efforts, stronger surveillance, and faster outbreak responses.

Although President Donald Trump signed an executive order in January to withdraw the U.S. from the WHO, PAHO officials said they still expect representatives from the CDC and the National Sustainability Commission to attend next month’s meeting.

In August, local health authorities declared the end of the West Texas outbreak, which had caused 762 infections over seven months, according to state data. Neighboring New Mexico also reported 100 linked cases and one adult death, bringing the total fatalities from the outbreak to three which were two children in Texas and one adult in New Mexico, all unvaccinated.

Despite these containment efforts, new clusters continue to appear in Utah, Arizona, and South Carolina, and investigators are examining whether these are connected to the Texas outbreak. If transmission persists into January, the United States could officially lose the measles elimination status it earned in 2000.

The CDC calls the elimination of measles one of the country’s most significant public health achievements, made possible through a highly effective vaccination program and improved control efforts across the Americas. However, MMR vaccine coverage in both the U.S. and Canada has been steadily falling, with sharper declines noted after the Covid-19 pandemic.

With flu infections starting to climb across Canada, doctors and public health specialists are preparing for a challenging influenza season. The concern centres on the global spread of a changing H3N2 strain that may not line up well with this year’s flu vaccine. Fresh federal figures released on Friday show that about two per cent of flu tests nationwide returned positive results last week. While that remains below the five per cent threshold Canada uses to officially declare a seasonal flu outbreak, it marks a clear rise compared to recent weeks.

Outside Canada, the current flu season has already been severe, with record case numbers reported in the Southern Hemisphere and an earlier-than-usual surge seen in parts of Asia and the United Kingdom. As winter approaches, experts say these trends could offer clues about what Canada might face. “This is the second year in a row that the Southern Hemisphere has seen higher-than-average influenza activity,” said Dr. Jesse Papenburg, a pediatric infectious disease expert at Montreal Children’s Hospital and the McGill University Health Centre, as per CTV News.

“When you look at case numbers, last year was likely the worst flu season Canada experienced in about ten years. Based on what we’re seeing so far, there’s a real possibility we could see a similar level of severity again,” he added.

Influenza A: What Is Leading To The Surge?

Some specialists believe a changing version of H3N2 is driving the early rise in cases. This form of influenza A is already known for causing more serious illness, particularly in older adults. What is raising extra concern this year is that recent mutations appear to be creating more distance between the circulating virus and the protection offered by the current flu shot. Dr. Danuta Skowronski, who leads influenza and emerging respiratory pathogen epidemiology at the B.C. Centre for Disease Control, is one of several Canadian experts closely tracking these changes, according to CTV News.

Influenza A: Experts Warn Of Vaccine Mismatch

Although the H3N2 subtype had remained relatively stable for years, Skowronski says it has recently begun showing sharper structural shifts as it spread into northern regions. These changes suggest the strain now circulating could be poorly matched to this season’s vaccine. The current flu shot is designed to protect against two influenza A strains, including H1N1 and H3N2, along with one influenza B strain. “There’s actually a fairly large gap between the H3N2 virus we’re seeing circulate and the one included in the vaccine,” Skowronski explained. “That’s not due to any error. It reflects how unpredictable and fast-changing influenza viruses can be.”

In a statement shared with CBC News, the Public Health Agency of Canada said it keeps close watch on respiratory virus trends around the world to identify patterns that could affect Canadians.

The agency also noted that flu data from the Southern Hemisphere does not always directly forecast what will happen in Canada, since seasonal patterns and population dynamics can differ.

“At this point, it’s still too early to say how severe Canada’s flu season will be,” the agency said, adding that factors such as which influenza subtype becomes dominant, the presence of other respiratory viruses, vaccine performance, and vaccination rates will all play a role.

Even if this year’s vaccine turns out to be less closely matched to the evolving H3N2 strain, all three experts emphasized that getting the flu shot remains important, especially for older adults across Canada.

U.S. health authorities have widened the approval of a closely debated medication designed to increase female libido, allowing the once-daily pill to be used by women over the age of 65. The decision, announced on Monday by the Food and Drug Administration, extends the drug’s use to older women who have already gone through menopause. The pill, Addyi, was originally cleared a decade ago for premenopausal women experiencing emotional distress linked to a low sex drive. Anisha Mathur, Founding Partner at Shepherd Law Associates, explained the development and what it means.

What Is Addyi?

Addyi, also known by its generic name flibanserin, is an FDA-approved prescription drug used to treat hypoactive sexual desire disorder, or HSDD, in women. HSDD refers to a long-term or recurring lack of sexual desire that leads to emotional distress or strain in relationships and cannot be explained by another medical condition, relationship difficulties, or medication side effects, according to the Cleveland Clinic.

Marketed by Sprout Pharmaceuticals, Addyi was once expected to become a major breakthrough in women’s health. However, the drug faced setbacks due to side effects such as dizziness and nausea. It also carries a strong safety warning about alcohol use. The FDA’s boxed warning, its strictest caution, notes that consuming alcohol while taking Addyi can lead to dangerously low blood pressure and fainting.

What Is Hypoactive Sexual Desire Disorder?

Hypoactive Sexual Desire Disorder, or HSDD, involves an ongoing reduction or absence of sexual thoughts, fantasies, and interest in sexual activity that causes significant personal distress or relationship tension. It is a common form of sexual dysfunction seen in both women and men. People with HSDD may experience low libido, little response to sexual stimulation, or a tendency to avoid sex altogether. Possible contributing factors include stress, relationship challenges, mental health conditions, certain medications, hormonal shifts, or past trauma.

The condition, which describes a distressing lack of sexual desire, has been recognised since the 1990s and is believed to affect a large number of women in the United States, based on survey data. After the commercial success of Viagra for men in the 1990s, pharmaceutical companies invested heavily in finding treatments for female sexual dysfunction. Diagnosis, however, remains complex because libido is influenced by many factors. After menopause, declining hormone levels bring biological changes and medical symptoms that further complicate assessment.

Addyi: FDA Approves Libido-Boosting Drug For Postmenopausal Women

U.S. health regulators have now expanded the approval of the controversial libido drug, allowing women over 65 to take the once-daily pill. The FDA’s announcement broadens its use to include older postmenopausal women.

According to CNN, diagnosing HSDD is challenging because sexual desire is affected by multiple physical, emotional, and psychological factors, particularly after menopause. Physicians are expected to rule out issues such as relationship stress, underlying medical conditions, depression, and other mental health disorders before prescribing the medication. The diagnosis itself remains debated, with some psychologists arguing that low sexual desire should not automatically be treated as a medical condition.

Before its approval in 2015, the FDA rejected Addyi twice, citing limited effectiveness and concerns over side effects. Its eventual approval followed a strong lobbying effort by the manufacturer and advocacy groups like Even the Score, which positioned the lack of treatment options for female libido as an issue of gender equality in healthcare.

Salad Dressing Recall: Why Are Salad Dressings Being Recalled?

According to the FDA and Costco, the recalled dressings and sauces may contain pieces of plastic, described as “plastic foreign material,” leading to a voluntary recall. The FDA noted that because many of these products were manufactured in large quantities for food service use, they were likely supplied to delis, cafeterias, and similar facilities. Distribution covered 27 states, including Arkansas, Colorado, Florida, Georgia, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Missouri, Nebraska, New Hampshire, New Jersey, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Texas, Virginia, Washington, and Wisconsin.

Salad Dressing Recall: What Does A Class II Recall Mean?

On its website, the FDA explains that a Class II recall is its second most serious category. It refers to situations where using or being exposed to the product could cause temporary or medically reversible health effects, while the chance of severe health consequences is considered low.

Salad Dressing Recall: What Should I Do If I Purchased These Products?

The FDA has not issued detailed guidance for consumers who may have bought the recalled items. As with any recall, the safest step is to avoid consuming the products and contact the retailer for information about returns or refunds. Costco stated in its advisory that customers should stop using the affected items and bring them back to their local Costco location for a full refund.
