A tradition we love: starting the World Health Summit at our #WHOHub in Berlin, welcoming @WHO colleagues from across the world, from HQ to regions to country offices. Great to be back. 

Wishing everyone a productive #WHS2026

[World Health Organization (WHO) @WHO]

The WHO Hub for Pandemic and Epidemic Intelligence in Berlin, Germany, is one of WHO’s key initiatives to better protect people around the world from pandemics and other health threats.

The Hub marks its fifth birthday this year by launching a new strategy to bring together countries and partners so that by 2030 new health threats can be detected and understood within 24 hours.

Thank you #Germany for the continuous support.

The three-year-long conflict in #Sudan has disrupted basic services, displaced millions, devastated the health system, and created the world's largest humanitarian crisis.

❗️Disease
❗️Malnutrition
❗️Violence
❗️Displacement

Sudan's people need peace.

#3YearsTooLong

[World Health Organization (WHO) @WHO]

Three years of conflict in #Sudan have led to a devastating humanitarian crisis. 

While WHO continues to provide aid wherever possible, we urgently need unhindered access to reach all people in need across Sudan. 

WHO is calling on all parties to silence the guns. People in Sudan need peace.

[Tedros Adhanom Ghebreyesus @DrTedros]

The two years of a deadly conflict in #Sudan have left millions of Sudanese people hungry, injured, sick and without homes.

Last summer, I visited Port Sudan, and the Adré crossing in Chad where Sudanese mothers and children are seeking refuge. Their sadness and despair still haunt me to this day.

Despite insecurity and access constraints, @WHO and partners are tirelessly trying to deliver humanitarian aid and health assistance to as many people as possible. But aid is not enough.

Sudanese people need peace. The best medicine is peace.

We urge the protection of civilians and health at all times and a commitment to lasting peace.
