The resurgence of measles in the U.S., with over 1,900 confirmed cases reported in 2026 alone, highlights critical gaps in vaccination coverage and outbreak management.

With decreasing MMR vaccine rates among kindergartners and pockets of unvaccinated populations, enhanced surveillance and targeted public health interventions are urgently needed to maintain herd immunity and prevent further outbreaks.

This underscores the importance of policy efforts focused on improving vaccine access and community engagement.

Big changes are coming to Medicaid cost sharing under the 2025 reconciliation law.

For the first time, states will be required to charge fees to adults on Medicaid expansion, potentially raising their out-of-pocket costs and creating new barriers to coverage. Early evidence links such cost sharing to reduced use of care and worse health outcomes, especially among those with chronic conditions. This shift could deepen health inequities for vulnerable populations.

Learn more about how these policies might impact access and affordability.

This brief explains current Medicaid cost sharing rules and changes made to cost sharing rules by the 2025 reconciliation law, reports on cost sharing amounts states currently impose on ACA expansion adults, and highlights literature on the impact of cost sharing.

Hantavirus infections are rare but can quickly escalate from mild flu-like symptoms to severe lung or kidney disease, with a fatality rate reaching up to 38%. This virus spreads through contact with wild rodents and their droppings, posing a serious risk if you're exposed.

There's no vaccine yet, making prevention focused on rodent control crucial. Learn how to spot symptoms and protect yourself here:

Medicaid coverage rules are a patchwork quilt across the U.S. Income limits for eligibility swing dramatically by state and demographic, leaving many unsure if they qualify. This guide breaks down who qualifies where, helping you avoid denied benefits and surprise medical costs.

The state you live in could make all the difference.

Medicaid eligibility varies by state, so explore income limits, covered groups, and state-specific benefits to confirm your eligibility before applying.

The federal government has released sweeping final regulations to reshape how health insurance exchanges and brokers operate under the ACA starting in 2027. These include tightened marketing rules to protect consumers, expanded eligibility for hardship exemptions, and new standards allowing plans without traditional networks.

These policies could mean more choice and cost control—but also complexity—in health coverage for millions.

What happens when health becomes part of the culture war?

A new study in Nature Human Behaviour suggests that political identity is now tied to health in ways public health can no longer ignore. Using long-term medical data and death records, researchers found that conservative Americans in one national cohort became less healthy than liberals during the 2010s and were more likely to die in the early 2020s.

The gap was not only about COVID-19. The researchers found that conservatives had higher deaths from internal causes such as heart disease, cancer, stroke, and diabetes. They also found evidence that right-leaning Americans report lower trust in doctors, less willingness to follow medical advice, and more skepticism about medications for chronic conditions.

This does not mean politics “causes” poor health. The authors are careful to say more research is needed. But the findings point to a serious public health challenge: if trust in medicine breaks down along political lines, then prevention, treatment, and emergency communication all become harder.

The takeaway is not to shame people. It is to rebuild trust. Public health messages need to meet people where they are, work through trusted messengers, and make care feel practical, respectful, and relevant.

Using individual-level medical data and death records, this study finds that conservatives in the USA experienced worse health and higher mortality than liberals during the 2010s. No significant gaps in biomarkers or mortality were present before the 2010s.

Mental health is often discussed as if it lived only in the brain. But our minds are shaped by much more than brain chemistry.

Food, sleep, movement, stress, social connection, technology, trauma, neighborhood conditions, and access to care all shape how people feel and function.

A recent podcast conversation between Secretary Kennedy and Dr. Ellen Vora raised important questions about the mind-body connection, nutrition, social media, exercise, and whole-person mental health care. Those questions deserve serious attention.

But public health has to push the conversation one step further.

It is not enough to tell people to eat better, sleep more, get outside, or put down their phones. We also have to ask who has access to healthy food, safe parks, affordable care, stable housing, supportive schools, and a real community connection.

A whole-person approach to mental health should not become another form of individual blame. It should help us build conditions where health is actually possible.

Imagine strawberries bursting with richer color and stronger aroma, packed with health-boosting compounds — all without sacrificing size, sweetness, or growth. Scientists have boosted a gene that could transform fruit quality sustainably, challenging old assumptions about genetic tweaks.

Could this mean better produce without the usual trade-offs? Read more:

A surprising genetic twist shows that boosting a seemingly ordinary “housekeeping” gene can dramatically improve fruit quality without any trade-offs. By increasing the activity of a tRNA-related gene in strawberries, researchers unlocked richer color, stronger aroma, and higher levels of health...

Ozempic and similar weight-loss drugs are hailed as breakthroughs, yet new research uncovers a dark side: people using these drugs face more social judgment than those losing weight through diet or even those who don’t lose weight. This stigma, rooted in ideas about “easy” weight loss, could worsen mental health and access to support.

What does this mean for how we treat weight management?

GLP-1 weight-loss drugs like Ozempic and Wegovy are often celebrated as game-changing solutions—but new research reveals a surprising social twist. People who lose weight using these medications may actually face more judgment than those who lose weight through diet and exercise—or even those wh...
