Which term describes illnesses with sudden onset and short duration affecting the body?

• A. Chronic illnesses
• B. Life expectancy
• C. Acute Infectious Diseases
• D. Globalization

Answer: (C)

Illnesses that come on suddenly and last for a short time are described as acute. The idea is rapid onset paired with a brief course. The term that matches this description among the options is acute infectious diseases, since it conveys both the sudden start and the typically short duration of such illnesses caused by pathogens. The other options don’t fit: chronic illnesses are long-lasting, life expectancy is a measure of how long people are expected to live rather than a description of illness duration, and globalization is unrelated to illness timing.
