Which area is included among the PBH's five areas?

• A. Epidemiology and stats
• B. Biomedical Sciences
• C. Agricultural science
• D. Social and Behavioral Sciences

Answer: (A)

Public health practice relies on five core areas that together cover the key ways we study and protect population health. One of these areas is Epidemiology and Biostatistics, which centers on understanding how diseases spread, who is affected, and why, using data to describe patterns and to test whether interventions work. This focus on measuring disease and analyzing health data is essential for surveillance, outbreak detection, risk-factor identification, and evaluating public health programs, making it a fundamental part of the PBH framework.

Agricultural science isn’t part of those core five domains, though it can influence health outcomes indirectly. Biomedical Sciences and Social and Behavioral Sciences are also recognized parts of the five, but the term Epidemiology and Stats specifically highlights the data-driven, population-level methods that are central to guiding public health actions.
