The current leading causes of death in the United States are which type?

• A. Chronic illnesses
• B. Infectious diseases
• C. Acute injuries
• D. Genetic disorders

Answer: (A)

Long-term, noncommunicable illnesses account for the majority of deaths in the United States. The leading causes—heart disease, cancer, chronic lower respiratory diseases, stroke, and Alzheimer’s disease—are chronic conditions that develop and progress over years, often linked to aging and modifiable risk factors such as smoking, poor diet, inactivity, and obesity. Because these diseases accumulate over time, they produce the highest mortality burden compared with other categories. Infectious diseases, while important, historically do not rank as the top cause of death; acute injuries and genetic disorders contribute as well but not at the scale of chronic illnesses.
