Since December 2017, WHO has documented:
- more than 10 400 attacks on health care
- across 29 countries and territories,
- resulting in more than 5700 deaths and 8500 injuries. 

Every attack puts lives at risk, deprives people of essential care and undermines the ability of health systems to respond when people are in need of urgent care.

Stop attacks on health care.

In 2026 alone, 911 health workers and patients have lost their lives to attacks on health care across 19 countries and territories. And nearly 1486 others have suffered injuries.

Often health workers put their duty of care above their own safety. Their loss leaves behind a grieving family, community, and a fragile health system.

Today is World Humanitarian Day.

We repeat.
HEALTH IS NEVER A TARGET.

Stop attacks on health care.

The #Ebola outbreak in #DRC remains a public health emergency of international concern, following the advice of today’s @WHO Emergency Committee meeting.

We call for the cooperation of all governments and all partners, working together as one, to scale up efforts even further, and raise the resources needed to protect communities over the coming months.

Updated recommendations to the government of DRC and other countries at risk will be issued in the coming days.

Strong country leadership is essential to achieving #HealthForAll.

That's why @WHO is building its new WHO Representative (WR) Talent Pipeline to identify and prepare the next generation of public health leaders to serve as WHO's most senior representatives at country level: https://t.co/kSLOElYCKT

We're looking for experienced public health leaders with strong international experience and a commitment to working with governments and partners across diverse country contexts.

For today's youth the digital world isn't separate from real life, it's part of it.

The content they consume, the interactions they have, and the experiences they navigate online can influence their mental health, sleep, diets, learning and relationships.

Recognising this doesn't mean banning screens.

It's about creating safer digital environments and equipping young people with the support, trust and guidance they need to thrive, both online and offline.

Vaccines protect people at every stage of life: from a child’s first days through adulthood and beyond.

In early childhood, immune systems are still developing, leaving young children more vulnerable to serious illness. That’s why most routine vaccines are given in the first two years of life, offering protection when it matters most.

As children grow into their teenage years, booster doses help keep that protection strong and respond to new and emerging health risks.

During pregnancy, vaccination plays a crucial role in protecting both parent and baby. Recommended vaccines help pass protective antibodies to babies before birth, giving them a safer start in life.

In adulthood and older age, the immune system naturally becomes less robust. Vaccines help reduce the risk of severe illness and hospitalization, helping people stay healthy and live longer.

Vaccination is about care, prevention and giving every generation the chance to learn, grow and thrive.

Catching cancer early and starting care right away can make a lifechanging difference for a child.

Early diagnosis consists of:
- knowing the symptoms
- accurate and timely diagnosis
- quick access to treatment

Let’s give every child diagnosed with cancer the brightest future.

Human papillomavirus (HPV) is the leading cause of cervical cancer.

Vaccination, along with regular screening, can prevent most cases.

The #HPV vaccine is safe and highly effective in preventing HPV infections that can cause cervical cancer and other HPV-related cancers.

🚨 Misusing antibiotics can affect everyone.

AntimicrobialResistance (AMR) occurs when bacteria, viruses, fungi and parasites no longer respond to medicines. Drug-resistant bacteria can spread and make infections harder to treat.

Let’s handle antibiotics with care and protect our communities!

#Alcohol is a depressant.

It might seem like a quick fix, but it interferes with brain chemistry and fuels anxiety. It affects serotonin and dopamine – the brain chemicals that regulate mood.

What feels like calm is often just numbness. You deserve support that helps you heal.

Did you know?

Nearly 20 million children in 2025 were unvaccinated or under-vaccinated. For every 3 children not fully vaccinated:

👉🏽2 never received a single dose
👉🏽1 started their vaccination but never completed the schedule.

Vaccination schedules can help you know when your child needs each dose, so they get protection when it matters most.

Not sure what’s next?

Check your child’s vaccination schedule or ask a health care provider.

Staying up to date with vaccines is one simple way to help protect your child’s health.
