1. Data Quality: Inaccurate or incomplete data can lead to misleading conclusions.
2. Changing Patterns: Diseases can mutate or change their patterns, making it difficult to track their progression.
3. Resource Limitations: Limited resources can hinder the ability to collect and analyze data comprehensively.
4. Ethical Issues: Ensuring patient confidentiality and obtaining informed consent can be challenging.
