 Humanitarian needs in Haiti have reached unprecedented levels since armed confrontation spiral in Port-au-Prince. These are five things to know about the escalation of this humanitarian crisis. 1. Health structures in the worst-hit areas are overcrowded by injured patients. Orders had to close due to insecurity. 2. Medical supplies are running dangerously low, including medicines and hospital beds. 3. Human restrictions due to insecurity remain a major obstacle to deliver desperately needed humanitarian aid. 4. Healthcare staff are unable to get to their workplaces, leaving hospitals understaffed. 5. Access to food, water, and fuel is now cut off in many communities with devastating consequences for the most vulnerable. Our call is simple. People's access to essential services and supplies must be guaranteed. The medical mission must be respected at all times and in all circumstances.
