Countries in the greater Horn of Africa are facing food insecurity not seen in decades with millions of people at risk of starvation. The region is reeling from the worst drought in 40 years and other climate shocks, years of conflict and instability, the impact of the pandemic and rising global food prices. A hunger crisis is a health crisis. Displacement often leads to an increase in infectious diseases, and malnutrition makes people more likely to get sick. Many families have left their homes in search of food, water and pasture for animals. Uprooted, they often lack access to health services just when they are needed most. This is why health response images are included in this photo gallery.
