Question

which of the following is not a factor that contributes to the emergence of infectious diseases?
improved sanitation
urbanization
global travel
climate change
question 2 (1 point)
what is the term for an infectious disease that is constantly present in a population?
endemic
outbreak
pandemic
epidemic

Explanation:

• First question: Improved sanitation reduces the spread of infectious diseases by reducing exposure to pathogens (e.g., clean water reduces water - borne diseases). Urbanization (crowded living conditions), global travel (facilitates pathogen spread across regions), and climate change (changes vector - borne disease ranges) contribute to infectious disease emergence.
• Second question:
• An endemic disease is constantly present in a population (e.g., malaria in some tropical regions).
• An outbreak is a sudden increase in cases in a limited area.
• A pandemic is a global outbreak.
• An epidemic is a widespread outbreak in a region.

Answer:

1. Improved sanitation
2. Endemic
