The exchange of health data on a global scale is crucial for several reasons:
1. _Disease Surveillance_: Timely sharing of data facilitates early detection and response to infectious disease outbreaks, which is vital for mitigating pandemics. 2. _Policy Making_: It provides evidence-based insights that can inform policy decisions and resource allocation. 3. _Research and Development_: Access to diverse datasets accelerates the development of new treatments and interventions. 4. _Health Equity_: It helps identify health disparities and target interventions to underserved populations.
