A) Breakdown in public health measures

C) Decreasing human resistance

Ans: A, B, E
Feedback: Many factors contribute to newly emerging or re-emerging infectious diseases. These include travel, globalization of food supply and central processing of food, population growth, increased urban crowding, population movements (eg, those that result from war, famine, or man-made or natural disasters), ecologic changes, human behavior (eg, risky sexual behavior, IV/injection drug use), antimicrobial resistance, and breakdown in public health measures. Emerging diseases are not caused by the aging population or decreased human resistance.
