Which population is often most vulnerable during a disaster?

Individuals with pre-existing health conditions are considered the most vulnerable population during a disaster for several reasons. These individuals often rely on consistent access to medical care, medications, and support services that can be disrupted during an emergency. Disasters can lead to the destruction of healthcare facilities, loss of medical supplies, and impede access to necessary treatments, exacerbating their health issues.

Furthermore, during a disaster, stress factors such as physical injury, emotional trauma, and environmental challenges can significantly worsen their existing health conditions. For example, a person with a chronic respiratory condition may struggle even more in an environment where air quality is poor due to debris and pollutants from a disaster. Additionally, individuals with physical disabilities may face further challenges in evacuation or accessing emergency care, further highlighting their vulnerability.

In contrast, populations such as young adults, experienced responders, and high-income individuals may not experience the same level of risk. Young adults are generally healthier and more mobile, experienced responders are trained to manage crises, and high-income individuals may have better access to resources and support, including transportation and alternative housing, during a disaster.
