Several factors contribute to the difficulty of precise measurement in epidemiology:
Data Quality: Data on disease prevalence and transmission rates can be incomplete or inaccurate due to underreporting, misdiagnosis, or delayed reporting. Population Dynamics: Populations are not static; migration, birth rates, and death rates all affect the accuracy of epidemiological measurements. Behavioral Factors: Human behavior is unpredictable and can change rapidly, affecting the spread of disease in unforeseeable ways.
