Question

what technology is used to track disease outbreaks through geographic patterns?
a. epidemiology
b. gis
c. remote sensing
d. zoonotic surveillance
which geographic factor is most associated with the spread of vector-borne diseases like malaria?
a. climate
b. infrastructure
c. pathogen ecology
d. urbanization

Explanation:

First Question:

• Option a: Epidemiology is the study of disease spread, not a technology.
• Option b: GIS (Geographic Information System) is used to analyze and visualize geographic data, including tracking disease outbreaks by geographic patterns.
• Option c: Remote sensing collects data from a distance, not specifically for tracking disease outbreaks’ geographic patterns.
• Option d: Zoonotic surveillance focuses on diseases transmitted from animals to humans, not geographic pattern tracking.

• Option a: Climate (temperature, rainfall) affects the habitat of vectors (e.g., mosquitoes for malaria), influencing their breeding and distribution, so it’s most associated with vector - borne disease spread.
• Option b: Infrastructure affects access to healthcare but not the primary geographic spread factor of vector - borne diseases.
• Option c: Pathogen ecology is about the pathogen’s environment, not a geographic factor.
• Option d: Urbanization can impact disease spread but is not the most associated geographic factor for vector - borne diseases like malaria compared to climate.

Answer:

b. GIS
