Despite seeing increasingly stable weekly numbers, the pandemic isn’t behind us. As we cautiously reopen the world, we must continue to observe the data and respond accordingly healthline.com/health-news/h…

Immersive exposure like this matters. Seeing health systems, policy, and innovation up close—across different contexts—changes how future leaders think about scale, delivery, and impact.
We are now into our second week of the UCL MBA Health Study Tour in the UAE, as part of this year's Global Health Challenge trip, and the learning continues to be both immersive and eye-opening. #UCLGBSH #MBAHealth #StudyTour #BusinessAndHealth #TheFutureOfHealth

Substance use is no longer a marginal issue—it’s a major driver of mortality and disability across the Americas. Strengthening prevention, early intervention, and treatment has to be a public-health priority, not an afterthought.
Drug use disorders among the top 10 risk factors contributing to all-cause mortality and disability in the Region, according to findings published in the @rpsp_pajph. PAHO urges countries to strengthen drug prevention programs. 🔗: Read more: paho.org/en/news/14-1-2026-d…

Quality carbs matter. Whole grains, vegetables, fruits, and pulses deliver fibre and nutrients that support long-term metabolic and cardiovascular health. Simple guidance, real impact.
Are you getting quality carbohydrates? Carbohydrates should come primarily from 🌾 whole grains 🥕 vegetables 🍌 fruits 🫘 pulses These are great sources of dietary fibre and nutrients bit.ly/3PULXwl #HealthyDiets

Foundational public health skills matter. Accessible, free training in epidemiology is critical for strengthening health systems—especially across the Americas.
Do you know our online course on Introduction to Epidemiology for Health Systems in The Americas? #PAHOVirtualCampus This #FreeCourse explains basic public health and epidemiology concepts. 🔗: campus.paho.org/en/course/ep…

Important reminder for parents and caregivers: when a child has an injury that hurts and swells, assume a fracture until proven otherwise.
Broken bones in kids: In children, injuries that hurt and swell up should be considered broken bones until proven otherwise. #HarvardHealth #TipoftheDay

Cutting back on sugary drinks is one of the simplest, most effective health moves we can make — small daily choices add up fast.
Sugar is addictive and keeps you hooked on unhealthy drinks like sodas & energy drinks. Drinking sugar-sweetened beverages is linked to weight gain and obesity. Break the cycle today for a healthier life! Limit intake of sweets & sugary drinks for a healthier lifestyle: 🥤 Fizzy drinks 🥤 Juice drinks 🥤 Liquid & powder concentrates 🥤 Flavoured water 🥤 Energy & sports drinks 🥤 Ready-to-drink tea & coffee 🥤 Flavoured milk drinks

Important reminder. After a head injury, symptoms like severe headache, vomiting, or confusion aren’t something to “wait out.” Getting checked quickly can make a real difference.
When head injury requires immediate care: If you have a severe headache, vomiting or feel confused after a head injury, you need medical evaluation right away. Have someone drive you to an urgent care center or emergency department. #HarvardHealth #TipoftheDay

Understanding how PrEP works matters. Clear, science-based information empowers people to make informed choices, reduce risk, and take control of HIV prevention — whether they’re using PrEP now or considering it.
Do you understand how PrEP works? 💊 #PrEP is a powerful tool for HIV prevention. Whether you’re using it, considering it, or just curious, knowing its science helps you make informed choices and feel more confident about protecting yourself. 🔗: paho.org/en/better-prep

Seasonal influenza and RSV circulating at the same time puts real pressure on health systems. Preparedness matters: strong surveillance, vaccination coverage, workforce readiness, and clear public communication are what make the difference when respiratory threats overlap.
🔴 PAHO urges countries across the Americas to remain vigilant and strengthen health system preparedness in response to the simultaneous circulation of seasonal influenza and respiratory syncytial virus. 🔗: paho.org/en/news/10-1-2026-p…

Early diagnosis and sustained treatment turn HIV from a fatal disease into a manageable condition—and restore dignity, longevity, and quality of life. Progress toward zero AIDS deaths is real, but only if access, continuity of care, and stigma reduction remain front and center.
Meet Mariana from Argentina 🇦🇷. With early diagnosis and continuous treatment, she overcame advanced #HIV disease and is now able to have a good quality of life. Recovery is possible. Let’s achieve Zero #AIDS Deaths by 2030! 🔗: paho.org/en/topics/advanced-…

Violence against children is widespread, takes many forms, and is entirely preventable. If a billion children are affected each year, this isn’t a side issue—it’s a global systems failure that demands urgency.
Each year, a billion children globally are estimated to suffer some form of violence, such as ✋ physical or emotional abuse ✋ child maltreatment (inc. corporal punishment) ✋ bullying ✋ sexual violence ✋ online violence Childhood violence is preventable and must stop NOW.

A timely agenda. Fiscal policy, prevention, and cancer control don’t usually get discussed in the same breath—but they should. Taxes on harmful products and early prevention are among the most cost-effective levers health systems have.
📣 Join our press conference on global health issues, with special focus on taxes on sugary drinks and alcoholic beverages, and on cervical cancer prevention and control, tomorrow at 13:30 CET (Geneva time)! @drtedros

A useful framing. Genomics isn’t destiny—it’s context. Understanding the “pages” helps us design better prevention, fairer care pathways, and smarter policy, especially as genomics moves from the lab into everyday health systems.
#Genomics can be explained through a simple metaphor: that each one of us is a unique book filled with pages that describe why we are the way we are. Genomics is the study of these pages. It’s how we can use our diversity to improve our future. Find out more about WHO's work on genomics: bit.ly/4sD9EdB

A simple but often overlooked point: good outcomes usually start with good basics. Clean, timely care—and knowing when not to over-intervene—still does a lot of the heavy lifting in medicine.
Certain wounds less likely to leave scars: If a wound is "clean"—even, straight, and free of dirt and bacteria—it will generally heal well and is less likely to produce a scar. #HarvardHealth #TipoftheDay

Mindfulness isn’t about clearing the mind—it’s about training attention. Small, regular moments of awareness can improve focus, emotional regulation, and resilience over time. Simple practice, real impact.
Cultivating mindfulness: Try a basic mindfulness practice. Sit quietly and focus on your natural breathing or the sounds around you. Allow thoughts to come and go without judgment, repeatedly returning your focus to the breath or sounds. #HarvardHealth buff.ly/iBeIT7Y

In strength training, quality beats speed. Slowing down reps shifts the focus to control, form, and true muscle engagement—small adjustments that compound into better strength over time. Harvard Health Publishing
Slowing down your repetitions using time under tension may help build stronger muscles. #HarvardHealth buff.ly/IFle5dR

Cervical cancer is one of the clearest examples of prevention working end-to-end. Vaccination, screening, and treatment are proven—what’s required now is consistent access and execution so elimination becomes reality.
January is cervical cancer awareness month! ✅Get informed ✅Get screened ✅Get vaccinated #CervicalCancer can be prevented & treated, if caught early bit.ly/47GIbzd #EndCervicalCancer
