Dehydration occurs when your body loses more fluids than you take in, preventing normal body functions.
A medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature.
A wound infection occurs when bacteria enter a break in the skin, causing inflammation, pus, and delayed healing.
Illness caused by eating contaminated food. Common in emergency situations where food storage is compromised.
Infections of the upper or lower respiratory tract, common in crowded shelter environments after disasters.
A life-threatening condition where the body's temperature regulation fails, causing body temperature to rise to dangerous levels.
Injuries caused by prolonged compression of body parts, common in building collapses and natural disasters. Can lead to life-threatening complications.
A condition where body tissues don't receive enough oxygen. Can occur in fires, confined spaces, high altitudes, or during chemical incidents.
Health effects from contact with hazardous chemicals, including industrial spills, gas leaks, or chemical weapons. Severity depends on the substance and exposure level.
Health effects from exposure to ionizing radiation, which can occur from nuclear accidents, dirty bombs, or medical facility incidents. Effects range from skin damage to systemic illness.
An intestinal inflammation causing severe diarrhea with blood or mucus. Common in disaster settings where sanitation and clean water are compromised.
An acute diarrheal infection caused by ingestion of food or water contaminated with Vibrio cholerae. Can cause death within hours if untreated. Common in post-disaster settings.
A fracture is a break in the continuity of a bone. In disaster situations, fractures are common due to falling debris, collapses, and accidents. Proper immobilization is critical to prevent further injury.
Burns are tissue damage caused by heat, chemicals, electricity, or radiation. Severity is classified by depth (superficial, partial-thickness, full-thickness) and percentage of body surface area affected.
Uncontrolled bleeding is a leading cause of preventable death after trauma. Rapid control of hemorrhage with direct pressure and tourniquets can be life-saving.
Cardiac arrest is the sudden loss of heart function, breathing, and consciousness. Without immediate CPR and defibrillation, death occurs within minutes. Every minute without CPR reduces survival by 10%.
Shock is a life-threatening condition where the body's organs don't receive enough blood flow and oxygen. It can result from bleeding, burns, dehydration, allergic reactions, or spinal injury.
Sprains are stretches or tears of ligaments, while strains affect muscles or tendons. Common in emergency situations involving physical exertion, falls, and debris navigation.
An asthma attack is a sudden worsening of asthma symptoms caused by airway inflammation and constriction. Can be triggered by smoke, dust, stress, or allergens common in disaster environments.
A stroke occurs when blood flow to part of the brain is interrupted or reduced, depriving brain tissue of oxygen. Every minute of delay means more brain cells die. Use the FAST test to identify stroke.
A heart attack occurs when blood flow to the heart muscle is blocked, causing tissue damage. Stress, physical exertion, and disrupted medication access during disasters increase risk.
Anaphylaxis is a severe, potentially life-threatening allergic reaction that can occur within seconds of exposure to an allergen. Immediate epinephrine administration is critical.
Tetanus is a serious bacterial infection caused by Clostridium tetani, which enters through wounds. The bacteria produce a toxin that causes severe muscle spasms. Disaster environments with debris increase wound contamination risk.
Snake bites can be venomous or non-venomous. In disaster situations where people are outdoors or in damaged shelters, encounters with snakes increase. Proper first aid can prevent serious complications.
Frostbite is tissue injury caused by freezing of skin and underlying tissues. Most commonly affects fingers, toes, nose, ears, cheeks, and chin. Can cause permanent damage and require amputation.
Carbon monoxide (CO) is a colorless, odorless gas that kills hundreds each year. After disasters, improper use of generators, grills, and heaters indoors causes mass CO poisoning events. CO is a leading cause of poisoning death post-disaster.
Hypoglycemia occurs when blood sugar drops below normal levels. In disaster situations, disrupted meal schedules, lost medications, and stress make diabetics particularly vulnerable. Can become life-threatening rapidly.
Drowning is respiratory impairment from submersion in liquid. Floods, storm surges, and water rescue situations create high drowning risk. Even near-drowning victims need medical evaluation for secondary complications.
Seizures are sudden, uncontrolled electrical disturbances in the brain. Can be caused by epilepsy, head trauma, high fever, hypoxia, or drug withdrawal. In disaster settings, head injuries and disrupted medication access increase seizure frequency.
A hypertensive emergency is severely elevated blood pressure that causes organ damage. Stress, disrupted medication access, and dietary changes during disasters can trigger dangerous blood pressure spikes.
