Despite the advancements in technology and methods, several challenges remain in the early identification of health issues:
1. Underreporting: In many regions, particularly in low-resource settings, underreporting of cases can delay detection. 2. Limited Resources: Lack of sufficient healthcare infrastructure and resources can hinder early identification efforts. 3. Diagnostic Limitations: Some diseases may present with non-specific symptoms, making early diagnosis challenging. 4. Privacy Concerns: The use of digital tools for surveillance raises concerns about privacy and data security.
