Despite its importance, epidemiology faces several challenges:
Data Quality: Ensuring accurate and comprehensive data collection can be difficult, particularly in resource-limited settings. Confounding Variables: Identifying and adjusting for confounders that may distort the true relationship between exposure and outcome. Ethical Considerations: Balancing the need for data with the rights and privacy of individuals. Emerging Infectious Diseases: Rapidly evolving pathogens can outpace public health responses, requiring constant vigilance and adaptability.
