Public health is essential during the early stages of any crisis, when conditions are unstable, and risks escalate quickly. Disasters often disrupt clean water supplies, destroy sanitation systems, and leave families in overcrowded shelters. These conditions allow diseases to spread rapidly, turning an already dangerous situation into a major health emergency. Humanitarian organizations act fast by launching public health measures such as vaccination campaigns, hygiene promotion, and water purification efforts. These lifesaving actions prevent outbreaks, reduce mortality, and help stabilize affected areas.
