Epidemiologists use various methods to study host populations, including:
Surveillance: Continuous monitoring of disease incidence and prevalence in a population. Cohort Studies: Following a group of individuals over time to assess disease development. Case-Control Studies: Comparing individuals with a disease (cases) to those without (controls) to identify risk factors. Cross-Sectional Studies: Analyzing data from a population at a single point in time to determine disease prevalence and associated factors.
