Verified step by step guidance1
Step 1: Understand the question is asking about the branch of science that studies the timing (when diseases occur) and the mode of transmission (how diseases spread).
Step 2: Review the definitions of each option: Immunology studies the immune system; Microbiology studies microorganisms; Pathology studies disease mechanisms and effects on the body; Epidemiology studies the distribution and determinants of health-related states or events in populations.
Step 3: Identify that the focus on disease occurrence patterns and transmission aligns with the study of populations rather than individual organisms or immune responses.
Step 4: Recognize that Epidemiology specifically investigates the incidence, distribution, and control of diseases in groups of people, including how diseases spread and when outbreaks happen.
Step 5: Conclude that the branch of science described in the question is Epidemiology.
