A world in crisis: confronting the drivers of health emergencies
Increasingly intense and prolonged humanitarian crises require urgent action to protect the world’s most vulnerable. In 2025, an estimated 305 million people will require humanitarian assistance. The growing scale of global challenges – such as the climate crisis, conflict, and infectious disease outbreaks – is outpacing available resources.
Every humanitarian crisis is a health crisis
Health is profoundly affected during crises
From trauma care to maintaining essential health services, humanitarian crises increase health needs and place extraordinary pressure on local health services. With such wide-ranging impacts, health must be at the heart of any humanitarian response. Without the quick and effective provision of health services, humanitarian crises can have profound and catastrophic health impacts on affected communities. In the darkest moments of a crisis, health services offer a lifeline, giving individuals and communities the strength to endure and the foundation to rebuild.
