Population-level health updates, prevention guidance, surveillance, and official advisories from public-health authorities.
CDC’s “Activity Levels” and “Illness Severity” indicators are designed to show community trends in respiratory virus spread and hospital burden. This guide explains what the levels can—and can’t—tell you, how wastewater fits in, and what practical “protect more” steps families and schools can take without panic.
A measles exposure notice is a reason for fast, calm action. Check documented immunity, confirm the exposure date, and contact a clinician or local health department quickly so you do not miss the short post-exposure window.
Parents and caregivers should stop using recalled Nara Organics infant formula right away, watch exposed babies for symptoms of infant botulism for one month, and seek emergency care promptly if signs such as poor feeding, trouble swallowing, floppy muscles, or breathing problems appear.
With U.S. measles cases at 2,030 as of June 4, 2026, now is a practical time to check who in your family needs one MMR dose, who needs two, and what to do if you are exposed before summer travel or camp.
CDC says emergency room visits for tick bites are higher than usual in many parts of the country. The best response is simple: prevent bites, remove attached ticks quickly, and watch for rash, fever, or other symptoms in the days and weeks afterward.
CDC says adults 75 and older, and adults 50 to 74 at higher risk of severe RSV illness, should get one RSV vaccine dose before the next respiratory virus season. The shot can be given any time, but late summer or early fall is the best window for most people who qualify.
U.S. measles activity is still climbing, and the biggest risk is to people who are not protected against the virus. Families, schools, childcare centers, and workplaces can lower the chance of spread by checking vaccination records, watching for symptoms, and acting quickly after a possible exposure.
OSHA updated its heat hazard program ahead of summer. Here’s what that means for inspections, who faces higher risk, and signs of heat illness.
New U.S. guidance says women 65 and older should be screened for osteoporosis, and some younger postmenopausal women should be screened sooner.
New CDC data show seasonal allergies affect about 1 in 4 U.S. adults and 1 in 5 children. Here’s how to spot them, treat symptoms, and know when to get care.
The 2025-2030 Dietary Guidelines talk a lot about “real food,” but the bigger everyday question is whether healthy choices become easier to afford, find, and fit real life. That is where the Advisory Committee’s health-equity lens may matter most.
The new federal dietary guidelines matter far beyond your kitchen. For most people, the clearest takeaway is to cut back on highly processed foods, sugary drinks, and refined carbs before fixating on the newer, more debated protein and dairy shifts.
The March 2026 Star Princess outbreak offers a practical lesson for cruise travelers: do not board while sick, report even mild vomiting or diarrhea quickly, and do not assume deep cleaning alone can stop norovirus.
Measles is still vaccine-preventable, but it spreads quickly when travel-related cases reach communities with lower local vaccination coverage. CDC says confirmed U.S. cases remain high in early 2026, and a new JAMA Network Open study suggests delayed early childhood shots can be an early warning sign that a child may also miss MMR on time.
CDC’s 2026 measles numbers show more than an outbreak headline. They show how quickly measles can find weak spots in community immunity, and why infants, some pregnant people, and people with severe immunocompromise may depend on others’ protection.
A new CDC analysis found that only about 1 in 4 U.S. women ages 18 to 44 reported enough leisure-time activity to meet both federal cardio and muscle-strengthening goals. Here’s what the guidelines actually mean in plain language, why strength training is often the missing piece, and how to start without an all-or-nothing approach.
If you think someone is overdosing on opioids, do not wait to see if they wake up. Updated U.S. first-aid guidance says to call 911, give naloxone if available, support breathing, start CPR if the person is not breathing normally, and stay until help arrives.
No, 10,000 steps a day is not an official U.S. fitness rule. Federal guidance still focuses on weekly activity minutes plus strength training, while newer studies suggest meaningful health benefits can begin below 10,000 steps for many adults.
A February 2026 recombinant mpox report has not changed the basic advice for most people in the United States: you cannot tell the strain by looking at a rash, and a new unexplained sore or skin lesion still needs medical evaluation.
Nearsightedness is becoming more common in U.S. children. Here’s what federal data show, why outdoor time matters, and which treatments can actually slow worsening—plus what families should know about exams, costs, and insurance.
The CDC has released its 2026 U.S. immunization schedules. Here’s what changed, how to read the color‑coded tables, who should review their records, and what the updates mean for insurance coverage, schools, and preventive care.
Most of the United States moved clocks forward on March 8, 2026, losing an hour of sleep. Research suggests that even this small shift can temporarily affect heart health, mood, driving safety, and workplace injuries—especially in a nation already short on sleep.
